Polymarket’s contract on whether Mitch McConnell casts a Senate vote by August 31, 2026 has fallen to a 1% chance of “Yes,” down sharply from the 22% level it held earlier in August. The event, “Will Mitch McConnell vote in the Senate by August 31?”, runs through 11:59 PM ET on August 31, 2026, and it asks a different, broader question than the one this article originally tracked: a Manifold Markets contract on whether McConnell would make a verifiable, live public appearance before August 3, 2026. That appearance market never reached 22% either — it held closer to 15%-16% through mid-July, including about 16% on July 11, 2026, when roughly 73% of the contract’s all-time volume changed hands in a single 24-hour window, before its resolution window closed at 11:59 PM ET on August 2, 2026. Both markets trace back to the same health mystery: on July 12, 2026, McConnell issued his first statement since a June 14 hospitalization, describing a fall and a mild case of pneumonia, and moved to a rehabilitation facility. Polymarket’s own market text ties the latest move to McConnell’s August 6, 2026 discharge from that facility and his plan for intensive physical therapy at home rather than a return to Washington, and it now puts the “No” side at 98.6%, citing “combined institutional and health constraints” as the stated reason. A separate Kalshi market on McConnell’s outright resignation reacted even more sharply to the July 12 statement, falling 12 percentage points, from 29% to 17%, in a matter of hours.

What the market is asking
The resolution bar for a “Yes”
The original contract lives on Manifold Markets, a play-money prediction platform where users trade shares in the outcome of real-world questions. The resolution criteria are strict: McConnell must make a live public appearance, or appear in clearly same-day public video, before August 3, 2026 — the contract’s resolution window closed at 11:59 PM ET on August 2, 2026 — with verification from an independent source such as C-SPAN, a Senate livestream, or a major news organization. A recycled photo or an unverified staff statement does not count.
That specificity matters. Many political questions are fuzzy, but this one has a clean bar: a dated, independently sourced sighting. Because the criteria are so concrete, the price becomes a fairly direct read on how likely traders think it is that McConnell is well enough, and willing, to be seen on camera within the window.
Why August 3 became the original cutoff
The August 3 deadline is not arbitrary. Under Kentucky’s 2024 vacancy law, House Bill 622, a Senate seat that becomes vacant before August 3 triggers a mandatory special election to fill the remainder of the term, while a vacancy on or after that date leaves the seat vacant until the winner of the regular November election is seated. That is almost certainly why the market’s creator drew the line at “before August 3” rather than picking a round number.
The odds and what they imply
Reading the Manifold appearance price
The Manifold appearance contract topped out at about 15%-16% implied probability of “Yes” through mid-July — 16% in one reading on July 11, 2026, as Tech Insider first reported, and 15% in another snapshot the same week — before its window closed at 11:59 PM ET on August 2, 2026. In prediction-market terms, implied probability is simply the current price of a “Yes” share read as a percentage. A reading in the mid-teens meant the crowd leaned toward “No” by roughly five-to-one, even after McConnell’s July 12 statement and his shift to a rehabilitation facility. In its final stretch, the contract showed 185 trades across 38 holders, with about Ṁ3,500 in liquidity — a small but active market for a single-event contract. That mid-teens reading now looks closer to the newer Polymarket contract’s own early-August level of 22% than to where that contract stands today: after McConnell’s August 6 discharge from rehab, it has fallen to just 1%, covered next.
Prices like this are not forecasts from a single expert. They are the weighted opinion of everyone willing to put stake behind a view, and they move as new information arrives. For readers new to the mechanics, our explainer on the way these odds are built and read walks through how a share price maps to a probability, and why a low number is a claim about likelihood rather than a certainty.
A new contract: Polymarket’s Senate-vote market
A higher bar than a public appearance
As of August 2026, the most current McConnell prediction-market read comes from a different platform and a different question. Polymarket alone lists roughly 500 active markets tied to McConnell as of September 2026, per Polymarket’s own count, spanning everything from the appearance and vote questions to his eventual resignation, and the flagship among them, Polymarket’s “Will Mitch McConnell vote in the Senate by August 31?” event now shows just a 1% chance of “Yes” — down from 22% earlier in the month — with the event window running through 11:59 PM ET on August 31, 2026, nearly a month later than the original Manifold contract’s August 3 cutoff. That August 31 version wasn’t even the first attempt at this question: an earlier Polymarket contract asking whether McConnell would vote by July 31 had already priced “Yes” at a flat 0% before that deadline came and went, so the near-certain “No” that later showed up on the August 31 contract was, in hindsight, a continuation rather than a new signal.
The two questions are related but not identical. The Manifold contract this article originally tracked asks only whether McConnell makes a live public appearance or same-day video; the Polymarket contract asks whether he actually casts a vote on the Senate floor, a higher bar that requires him to be well enough to resume official business, not just to be seen on camera. A “Yes” on the vote question would also satisfy the appearance question’s spirit, even though the two contracts resolve independently and on different clocks.
What today’s price implies
Polymarket is a real-money, event-contract exchange, distinct from both the play-money Manifold platform and the CFTC-regulated Kalshi exchange discussed below, and it is not available to US persons. The category McConnell’s contract sits in is far from a niche corner of the site: third-party tracker Polymarket Explorer measured $510 million in volume, 153,000 traders, and 1.81 million trades across Polymarket’s Congress-focused markets in June 2026 alone, giving the McConnell contracts a deep, liquid pool of counterparties. A 1% “Yes” price — a 99% “No” consensus, or 98.6% by Polymarket’s own count — means traders now see a Senate vote by August 31 as all but ruled out, a notably colder read than the appearance market’s mid-teens peak ever showed. Polymarket’s own market text ties that shift to McConnell’s August 6, 2026 discharge from his rehabilitation facility and his plan to continue intensive physical therapy at home rather than return to Washington, which traders appear to be reading as a sign a floor vote before the August 31 deadline is increasingly unlikely.
Polymarket’s resolution criteria for what counts as a “vote” are broad. The market defines a qualifying vote as any bill, resolution, nomination, motion, or other measure that comes before the Senate floor, not just a marquee piece of legislation. McConnell casting a single procedural vote or voting on one judicial nomination would satisfy the contract just as well as a headline bill — the requirement is simply that he votes on something, on the record, before 11:59 PM ET on August 31, 2026.
Who confirms a “Yes,” and why that matters
Polymarket lists the United States Senate as this market’s resolution source. Not a news outlet, not a staff statement, not a photo. That detail sounds procedural, but it sets a hard floor: the contract pays out only when McConnell’s name shows up against an actual roll-call or voice vote in the chamber’s own record, the same record C-SPAN and the Senate’s public site already publish for every vote taken. A sympathetic press release or an off-camera assurance from a colleague doesn’t move the needle. The market needs the government’s own record to show a vote happened, and that cuts both ways: a routine procedural motion that never makes the news would still resolve the contract “Yes,” as long as it’s logged on the floor before the deadline. That ties directly into the misinformation risk described above. When the resolution source is a public record rather than a claim anyone can make, rumors have less room to swing the price.
Why one Polymarket page reads 1% and another reads 0%
Check both parts of Polymarket’s site and the number isn’t always identical. The markets list rounds this contract to a 1% chance of “Yes.” The event page’s own crowd-sourced probability line reads 0% for “Yes.” Both are accurate. They’re just rounding a thin sliver of probability two different ways, since whole-percentage displays typically round anything under about half a point down to 0% and anything above that up to 1%. Either number leads to the same read for a trader: with the “No” side priced near 98.6%, McConnell casting a floor vote by August 31 is treated as close to ruled out, not literally impossible.
The August 6 discharge and the drop to 1%
Why “discharged” didn’t mean “returning”
The clearest catalyst for the move from 22% to 1% is dated precisely. Polymarket’s own market text says McConnell was discharged from his rehabilitation facility on August 6, 2026 and plans to continue intensive physical therapy at home rather than return to Washington. Traders appear to be reading “discharged” and “home” together: leaving a rehab facility sounds like the more favorable half of that update, but going home instead of back to the Senate is the detail that matters for a contract that only pays out on an actual floor vote. The result is a market that now prices the “No” side at 99% — 98.6% by Polymarket’s own count — a sharper consensus than the roughly five-to-one “No” lean the original Manifold appearance market ever showed.
That reframes the earlier 22% reading as a brief, early-August high point rather than a settled level. It came before the discharge news, at a moment when McConnell’s exact recovery timeline was still unknown and traders were pricing some chance that “well enough to leave rehab” would also mean “well enough to return to the floor.” The August 6 update separated those two questions: he is well enough to leave a facility, but his own camp’s plan is home-based therapy, not a trip back to Washington before August 31.
What “institutional and health constraints” means
Polymarket’s own market description is unusually specific about its reasoning. Rather than pricing “No” purely on the absence of news, the listing attributes its 98.6% “No” figure to what it calls “combined institutional and health constraints.” The health half of that phrase tracks the reporting already on the record: doctors linked McConnell’s June 14 fall to complications from his childhood polio, ruled out a stroke, heart attack, concussion, or broken bone, and diagnosed a mild case of pneumonia during his hospital stay. The institutional half is a separate, more mechanical constraint: the Senate has no formal system for proxy voting, so a senator who cannot appear on the floor cannot have a colleague cast a vote on his behalf, no matter how engaged he remains from home. That combination is why traders are pricing the contract close to a near-certainty of “No” rather than the merely-elevated range a health story alone might imply: even a faster-than-expected recovery would still need to clear the logistics of a trip to Washington and a floor appearance before 11:59 PM ET on August 31, 2026.
Why the volume spiked
A cluster of early-July reporting
The eye-catching signal at the time was not the level of the odds, it was the speed of the trading. Around 73% of the market’s entire all-time volume traded in a single 24-hour window on July 11, placing it among the most active contracts on the platform for that period. Sudden concentration of volume usually means fresh news, and in this case the news was a cluster of reporting in early July that turned a quiet absence into a national story.
On July 6, The Washington Post published a status summary noting McConnell had not appeared publicly or issued a statement since June 14. On July 7, CNN, Forbes, NBC News, Al Jazeera, and Fortune all ran detailed pieces on the hospitalization and the lack of official explanation. Then, on July 10, CNN reported that new video showed McConnell being loaded into an ambulance on a stretcher on the morning of June 14, which pushed the story back to the top of the news cycle. Each of those beats is the kind of event that sends traders into a thin market at once, and the same pattern repeated, on a smaller scale, when McConnell’s July 12 statement landed.
What the reporting actually establishes
The hospitalization and the July 12 statement
Here is what named, mainstream outlets have confirmed, separated from speculation. McConnell, the 84-year-old Kentucky Republican and former Senate GOP leader, was hospitalized on June 14, 2026. According to CNN, he was found unconscious that morning and transported by an Advanced Life Support ambulance, and police scanner audio referenced CPR at his residence. His last recorded Senate vote was June 11, 2026, three days before the hospitalization.
For nearly a month, his office declined to give a diagnosis, treatment timeline, or return date, saying only that he was “receiving excellent care” and “continues to improve.” That changed on July 12, 2026, when McConnell issued his first personal statement since the hospitalization, releasing it alongside a photo of himself holding that day’s Washington Post to establish the date. He said a fall at his Washington home left him briefly unconscious, and that he also dealt with a mild case of pneumonia during his hospital stay. According to his attending physician, doctors ruled out a broken bone, a concussion, a heart attack, a stroke, and any tumor or hemorrhage; the fall was attributed to complications from McConnell’s post-polio condition, which has caused him several falls over the past year. McConnell has since moved from the hospital to a rehabilitation facility for physical therapy and said he remains fit to serve and has “every intention of finishing the job,” though he will not return to the Senate floor to vote “quite yet.” Several senior Republicans, including Senate Majority Leader John Thune, said earlier in July that they had spoken with McConnell and described him as alert. As of July 20, 2026, McConnell had not made a live appearance or same-day video that met the appearance market’s independent-verification bar. His absence continued through the end of the window: The New York Times and The Guardian both reported on July 27, 2026 that McConnell had still not appeared in public since mid-June, and a follow-up New York Times piece on August 1, 2026 covering Kentucky’s annual Fancy Farm picnic — a political event McConnell has attended for decades — confirmed he was absent from that as well. That contract’s window has since closed and Manifold has resolved it NO; the Polymarket Senate-vote contract covered above is now the more current gauge. His office’s most recent update came on August 6, 2026, confirming his discharge from the rehabilitation facility and a shift to physical therapy at home.
Missed votes and what they mean for a 53-47 Senate
By this update, McConnell has missed 51 Senate floor votes since his last recorded vote on June 11, 2026. In a chamber split 53-47 along party lines, a single absent Republican does not flip outcomes on its own, but it does shrink Senate GOP leadership’s margin for error on close, party-line business and leaves one fewer reliable vote available on any measure where defections are possible — the same dynamic that let four Republicans help pass the Iran-related resolution described below. McConnell’s office says he continues to engage with staff and colleagues on Senate business from home, but that engagement cannot substitute for a floor vote, which is the only action that can resolve the “No” side of the Polymarket contract before the August 31 deadline.
A separate market: Kalshi’s resignation odds
How the resignation market reacted to the July 12 statement
The Manifold contract tracked in this article asks only about a verified public appearance. A different question, whether McConnell resigns his seat outright before his term ends, trades separately on Kalshi, the CFTC-regulated exchange. That resignation market moved sharply on July 12, 2026, dropping 12 percentage points, from 29% to 17%, within hours of McConnell’s statement that he has “every intention of finishing the job” — a swing independently confirmed by market-data aggregator Octagon AI, whose own tracking of that same Kalshi contract had opened even higher, at 44.5% “Yes,” before the news cut it down, and which continued to ease to 29.5% by August 2026. Action Network, another odds tracker, had that same Kalshi contract running as high as 31% on July 8, 2026 — four days before McConnell’s statement — underscoring just how much ground the resignation odds gave up once that statement landed. The slide has kept going since: as of September 2026, Kalshi’s own contract — which has logged $3,699,103 in total trading volume — prices McConnell’s resignation at just 3%, the coldest reading any tracker has shown on the question.
The two contracts ask different questions and should not be read as interchangeable, but the reaction lines up with the reporting: traders treated the statement as evidence McConnell plans to stay in the Senate rather than step down, which cut the resignation price nearly in half. It did not resolve the appearance market this article tracks, since a written statement and photo still fall short of a verified live sighting.
A third tracker adds nuance rather than confirmation. Signal Bureau, which separately follows the resignation question, showed a last crowd price of 39.5% on July 13, 2026 — a day after McConnell’s statement and still well above Kalshi’s post-statement 17%. That gap shows not every pricing source moved as decisively as Kalshi did: some slice of the market still treated an early departure as a live possibility even after McConnell said he intends to finish his term.
That divergence proved temporary. By July 25, 2026, a Kalshi-linked tracker put the resignation market back at about 17%, down from the higher readings recorded earlier in the month, and Octagon AI’s own read kept drifting lower through August 2026, settling at 29.5% after opening as high as 44.5%. The decline didn’t stop there: tracker CoinGape put Polymarket’s own McConnell-exit probability at 11% in August 2026, and by September 2026 Yahoo News reported resignation odds had fallen to just 7% heading into the midterms, roughly matching Kalshi’s own 3% reading. Rather than settling further apart, the measures have converged hard toward the low single digits — another sign the crowd increasingly expects McConnell to finish his term rather than resign early.
Polymarket runs its own resignation market too
Kalshi and Signal Bureau are not the only venues pricing McConnell’s longer-term future, and Polymarket itself is not new to the question. An earlier Polymarket contract asking whether McConnell would retire before July resolved at a flat 0% “Yes” back in July 2025, a full year before the June 2026 hospitalization — a sign traders had already priced out an early departure long before this health scare began. Polymarket’s current version of that question, “Mitch McConnell steps down from Senate before his term ends?”, resolves by January 3, 2027 — when his current term expires — rather than tracking the August 31 vote deadline covered above. As of September 2026, that contract prices resignation at just 8% “Yes” versus 92% “No” — a sharp drop from the 27% level it held earlier, and now roughly in line with Kalshi’s own 3% reading and the 7% figure Yahoo News reported for the same question heading into the midterms. The gap is worth noting rather than resolving: Polymarket’s vote-by-August-31 contract and its own resignation contract are asking different questions on different clocks, so it is entirely consistent for traders to treat a floor vote in the next few weeks as all but ruled out (1%) while now also pricing in less than a one-in-ten chance that McConnell leaves office altogether before his term runs out in January 2027. Read together, the two Polymarket contracts suggest traders view “returns to vote by August 31” and “finishes the term without resigning” as largely separate bets, not two readings of the same underlying probability.
Who and what is involved
McConnell’s health history and political career
The central figure is McConnell himself, who led Senate Republicans from 2007 through the start of 2025 and announced in February 2025 that he would not seek reelection in 2026. His health history is part of the backdrop: a fall in 2023 that caused a concussion and a fractured rib, a separate fall in 2024, and public episodes in which he briefly froze while speaking. He also had polio as a child, which affected his mobility and which his physician has now linked to this year’s falls.
Why a 53-47 majority raises the stakes
The political stakes extend beyond one senator. Republicans hold a narrow 53-47 Senate majority, and McConnell’s absence has already had consequences. Per Fortune and Al Jazeera, his missing vote helped Democrats pass a resolution opposing President Donald Trump’s military action in Iran, with four Republicans breaking ranks. Kentucky Governor Andy Beshear, a Democrat, sent a formal letter to McConnell’s office requesting a transparent health update, arguing that speculation serves neither the senator nor his constituents.
A note on misinformation
An information vacuum invites fabrication, and this story has already produced some. Snopes debunked a fake image purporting to show McConnell in a hospital bed. That is a useful reminder for anyone trading or reading on this topic: the market’s resolution language specifically requires independent verification precisely because unverified images and secondhand staff assurances are easy to generate and hard to trust. McConnell’s own July 12 photo, dated by the newspaper he was holding, was widely read by outlets as a direct answer to that kind of doubt, even though it still falls short of the “live” bar the market itself requires. Traders pricing “Yes” on either the appearance or the Senate-vote contract are effectively betting that a credible, dated sighting or floor vote clears that bar before each contract’s deadline.

Why a tech and finance reader should care
A clean case study in price discovery
Set aside the specific politics and this is a clean case study in how prediction markets metabolize an event with a hard deadline and a binary outcome. The contract has a fixed end date, an unambiguous resolution rule, and a steady drip of public information, which is close to the ideal setup for price discovery. When 73% of lifetime volume trades in a day, as it did on July 11, you are watching a market repricing in real time as headlines land — even though, in this case, the reaction held the price in the mid-teens rather than sending it sharply higher. The newer Polymarket contract, which reframes the same underlying question around a Senate vote rather than a mere appearance, shows how quickly a related market can reprice on a single data point: an early-August reading near 22% fell to just 1% within days of McConnell’s August 6 discharge update, a colder read than the appearance market’s mid-teens peak ever showed.
It also illustrates the limits of these tools. Manifold is a play-money venue, so the dollar stakes are not comparable to a regulated exchange, and thin markets can swing on relatively few trades. Readers weighing where real-money political and event contracts trade can start with our primer on the CFTC-regulated US exchange Kalshi, and see how a similar political question behaved in our coverage of the market on Trump’s next Labor Secretary. For another live Manifold example, our writeup on the 2026 Tour de France odds shows how the same platform prices a very different kind of question, and the market on an AI perfect score at the 2026 IMO shows how deadline-driven contracts resolve.
What a sub-1% price means for existing positions
The move from 22% to 1% (or 0%, on the event page’s rounding) isn’t just a headline number. It’s a mark-to-market loss for anyone who bought “Yes” shares before the August 6 discharge update, and the dollars involved are real: tracking site Prediction Hero put open interest on McConnell-related Polymarket contracts at roughly $1,091,103,990 as of August 2026, meaning that repricing is playing out across more than a billion dollars in outstanding positions. A share bought near the early-August high is now worth a small fraction of its purchase price on paper, with the August 31 deadline set to confirm that loss in full or, in the unlikely event of a floor vote, pay out in full. That gap between near-zero and zero is normal this close to a contract’s resolution window. Prices rarely trade at a literal 0% or 100% before a deadline, because someone has to be willing to take the other side, and a small band of traders will keep pricing in tail risk (a sudden recovery, a surprise procedural vote, an unplanned floor appearance) right up until the contract closes at 11:59 PM ET on August 31, 2026. Traders who want out before then can still sell, but only at whatever the current bid reflects, which is exactly why the 1% and 0% readings matter beyond a research footnote for anyone still holding a position.
What to watch next
Four signals worth tracking before August 31
The Manifold appearance contract’s window has already closed (11:59 PM ET, August 2, 2026), so that specific catalyst has passed. What matters now is the newer Polymarket contract, which runs through 11:59 PM ET on August 31, 2026 and asks a higher-bar question: not just whether McConnell is seen, but whether he casts a Senate vote. Watch for four things specifically: any dated appearance or floor vote — on any bill, resolution, nomination, motion, or other measure — verified by C-SPAN, a Senate livestream, or a major outlet; any further update on McConnell’s at-home physical therapy, confirmed underway since his August 6 discharge, and whether it is expected to clear him for floor votes before the deadline; any further movement from Kentucky officials, since the state’s HB 622 succession rules made the original August 3 date legally meaningful and could still matter if McConnell’s status changes before his term ends; and whether the Kalshi, Signal Bureau, and Polymarket resignation trackers — last showing 3%, 17%, and 8% respectively as of September 2026 — hold steady or converge further as new reporting emerges. Each would move the Polymarket vote contract, and its drop to a 1% “Yes” (99% “No”; 98.6% by Polymarket’s precise count) shows traders now see a floor vote before the end of August as effectively priced out, with 22 days left on the clock.
Frequently asked questions
What do the 15%-16%, 22%, and 1% figures mean? The 15%-16% range was the Manifold “Yes” price on the original appearance question (a verifiable, live appearance before August 3, 2026) through mid-July 2026; that contract’s window closed August 2, 2026 and Manifold has since resolved it “No.” The 22% figure was Polymarket’s “Will Mitch McConnell vote in the Senate by August 31?” contract in early August, before McConnell’s August 6 discharge from rehabilitation. The current figure is 1%: Polymarket’s “Yes” price as of this update, after traders read the August 6 news — discharge to home-based physical therapy rather than a return to Washington — as lowering the odds of a floor vote by August 31. The three numbers describe different questions, different platforms, or different points in time, not the same contract moving in one continuous line.
Is real money at stake? Manifold is a play-money platform, so those prices are not regulated financial contracts. Polymarket is a real-money event-contract platform, though like Kalshi it is not available to US persons. The prices on all three still aggregate opinion, but the stakes differ by platform.
What would have resolved the appearance market “Yes”? A live public appearance, or clearly same-day public video, before August 3, 2026 (by 11:59 PM ET on August 2) — the window that has now closed — verified by an independent source such as C-SPAN, a Senate livestream, or a major news organization. A recycled photo or an unverified statement did not count, which is why McConnell’s July 12 written statement and photo did not resolve the market on its own.
What happened when the appearance deadline passed? If no independently verified live appearance or same-day video occurred before the 11:59 PM ET, August 2, 2026 cutoff, the Manifold contract resolves “No.” This update did not find independently verified reporting confirming the final outcome; readers can check the Manifold market page directly for its resolved status.
Why did volume spike? A cluster of early-July reporting, capped by CNN’s July 10 ambulance video, drove the initial spike on July 11. A second, smaller wave of trading followed McConnell’s July 12 statement, though it held the appearance market in the 15%-16% range — a level that, as of this update, is actually higher than the newer Polymarket Senate-vote contract’s current 1% reading, following McConnell’s August 6 discharge update.
Why does the market use August 3, 2026 as its deadline? The date matches Kentucky’s HB 622 succession law: a Senate vacancy before August 3 triggers a mandatory special election, while a vacancy on or after that date leaves the seat vacant until the regular November election winner is seated. The Manifold contract mirrored that cutoff, closing at 11:59 PM ET on August 2, 2026.
Has McConnell been seen publicly? As of the original appearance market’s close on August 2, 2026, no independently verified live appearance had been confirmed by this update since June 14. McConnell broke his silence on July 12 with a written statement and photo explaining the hospitalization, and his office said he was in a rehabilitation facility and improving. On August 6, 2026, his office confirmed he was discharged from that facility, with plans to continue intensive physical therapy at home rather than return to the Senate floor. The newer Polymarket contract on a Senate vote by August 31 — now pricing just a 1% chance of “Yes” — is the more current gauge of his return to active duty.
Is there a separate market on whether McConnell resigns? Yes, and there are several. Kalshi runs a resignation contract that fell 12 percentage points, from 29% to 17%, on July 12, 2026, after McConnell said he has “every intention of finishing the job”; market-data aggregator Octagon AI’s own tracking of that contract had opened even higher, at 44.5% “Yes,” and eased further still to 29.5% by August 2026. A second tracker, Signal Bureau, priced the same question at 39.5% on July 13, 2026 before converging back toward 17% by July 25, 2026. By September 2026, Kalshi’s own contract — which has now logged $3,699,103 in trading volume — had fallen further still, to just 3%. Polymarket separately lists its own resignation contract, resolving January 3, 2027, which CoinGape had at 11% in August 2026 before it eased to just 8% “Yes” by September 2026 — in line with Yahoo News’s separately reported 7% figure heading into the midterms.
Does Polymarket have its own market on McConnell resigning? Yes, separate from both Kalshi’s and Signal Bureau’s resignation trackers. Polymarket’s “Mitch McConnell steps down from Senate before his term ends?” contract resolves by January 3, 2027 and, as of September 2026, prices resignation at just 8% “Yes” versus 92% “No” — down from 27% earlier and now close to Kalshi’s 3% reading and Yahoo News’s reported 7% figure, though it is a different question from the August 31 vote contract this article otherwise tracks.
What is the new Polymarket contract about? Polymarket’s “Will Mitch McConnell vote in the Senate by August 31?” asks whether McConnell casts an actual Senate vote by 11:59 PM ET on August 31, 2026 — a higher bar than the original appearance question, and a later deadline. It traded near 22% in early August before McConnell’s August 6 discharge from rehabilitation; as of this update it shows just a 1% chance of “Yes” (a 99% “No,” or 98.6% precisely).
What counts as a “vote” for the Polymarket contract? Polymarket defines it broadly: any bill, resolution, nomination, motion, or other measure that comes to a vote on the Senate floor satisfies the contract. McConnell does not need to vote on a high-profile bill — a single routine procedural motion or judicial nomination would be enough to resolve the market “Yes,” as long as it happens before the August 31, 2026 cutoff.
Why did the odds drop from 22% to 1%? Polymarket’s own market text ties the move to McConnell’s August 6, 2026 discharge from his rehabilitation facility. His plan, as described in that update, is to continue intensive physical therapy at home rather than return to Washington — language traders read as lowering the odds of a floor vote before the August 31 deadline, pushing the “No” side to 99% (98.6% by Polymarket’s own count), which the market’s text attributes to “combined institutional and health constraints.”
How many Senate votes has McConnell missed? At least 51 Senate floor votes as of this update, dating back to his last recorded vote on June 11, 2026, three days before his hospitalization. His office maintains he continues to engage with staff and colleagues on Senate business from home, but that does not count as a floor vote for either the missed-vote tally or the Polymarket contract’s resolution.
What source does Polymarket use to resolve this market? The United States Senate itself. The contract resolves against the chamber’s official record of roll-call and voice votes, not news coverage, a staff statement, or a social media post. Even a low-profile procedural vote would count, as long as McConnell’s name is logged against it before 11:59 PM ET on August 31, 2026. That’s a narrower path to “Yes” than it might sound, but a real one, since the Senate logs even minor motions and nominations in the same public record.
