Traders Just Piled Into the “Avengers: Doomsday” Box Office Record Market, and It Sits at 43%. A Manifold market asking whether Avengers: Doomsday will post the biggest opening weekend of all time trades at 43% implied probability as of October 25, 2026, with roughly 38% of its lifetime volume changing hands in the past 24 hours. The catalyst is a wave of presales reporting that put the film’s worldwide advance sales above $125 million, nearly two months before its December 18 release. The bar is unusually precise: the market resolves YES only if the film’s domestic opening weekend clears $360,091,572, the record Spider-Man: Brand New Day set in July 2026.

What This Market Actually Asks
The contract is titled “Avengers: Doomsday” breaks the record for the biggest opening weekend of all time? and it is hosted on Manifold, created by the user Ziddletwix. Its resolution language is narrower than the headline suggests, and the distinction matters for anyone reading the 43% number.
The market resolves YES only if Doomsday records a domestic (United States and Canada) opening weekend gross above $360,091,572, with Box Office Mojo named as the resolution source. It does not pay out on a worldwide opening record, a December record, or a biggest-opening-of-2026 outcome. Three of those four framings have circulated in coverage this week, and they are not interchangeable. A film could post the largest global debut in history and still resolve this market NO.
Scale is worth stating plainly. The market has logged 159 trades across 40 holders. Manifold markets of this type run on mana, the platform’s internal currency, rather than cash stakes. That makes the 43% figure a useful aggregation of informed opinion but a weaker financial signal than a comparably priced contract on a cash-settled venue. Readers new to how these prices are constructed may want our primer on reading Manifold market odds.
The Odds as of October 25, 2026
As of October 25, 2026, the market prices YES at 43%. The 24-hour activity burst is the notable part rather than the level itself: approximately 38% of all volume the market has ever seen traded in a single day, which ranks it among the most active contracts on the platform over that window.
A 43% price on a question with a hard numeric threshold carries a specific meaning. Traders are not saying Doomsday will underperform. They are saying it is slightly more likely than not to land below $360.09 million domestically while still posting one of the largest openings ever recorded. Those two statements are entirely compatible, and the gap between them is where the disagreement lives.
Why the Money Moved This Week
The most concrete trigger in the past several days is presales reporting published October 24 and 25 claiming Doomsday has passed $125 million in worldwide advance ticket sales, well ahead of Dune: Part Three, which shares its December 18 date. That figure follows an earlier milestone on October 6, when trackers reported the film crossing $100 million in global presales.
One caveat deserves emphasis, because much of this week’s coverage dropped it. The $100 million and $125 million worldwide figures are tracker estimates that Disney has not officially confirmed. The only presales number the studio has put its name to is a domestic one, discussed below. Treating an unconfirmed global estimate as a verified domestic indicator is the single most common error in the current reporting cycle, and it plausibly explains part of the buying pressure.
What Disney Has Actually Confirmed
Disney CFO Hugh Johnston said at the Goldman Sachs Communacopia and Technology Conference that Doomsday had crossed $50 million in domestic presales with roughly 100 days remaining before release. Disney also reported that more than 70% of those sales were for Infinity Vision showtimes, the studio’s premium large-format presentation, which carries higher ticket prices and materially raises per-admission revenue.
The pace comparison is genuinely favorable. Doomsday crossed $40 million in domestic presales with about 100 days left on the clock, while Spider-Man: Brand New Day did not reach that mark until roughly 40 days before its opening. On velocity, the Marvel film is ahead of the record holder at the equivalent point in its rollout.
The level comparison is less favorable. Brand New Day reportedly finished with about $150 million in presales by the day before it opened. Doomsday‘s confirmed domestic figure stands at $50 million with the final, heaviest selling window still ahead. Whether it closes that gap is the open question, and the 43% price is roughly what you would expect from traders who respect the velocity but will not extrapolate it.
The Record It Has to Beat
Spider-Man: Brand New Day opened on July 31, 2026, and took $360,091,572 domestically, displacing Avengers: Endgame‘s $357,115,007 from April 2019. The margin was about $3 million, or under 1%. It also set a preview-night record of $72 million from Thursday previews, ahead of Endgame‘s $60 million.
| Film | Domestic Opening Weekend | Year |
|---|---|---|
| Spider-Man: Brand New Day | $360,091,572 | 2026 |
| Avengers: Endgame | $357,115,007 | 2019 |
| Spider-Man: No Way Home | $260,138,569 | 2021 |
| Avengers: Infinity War | $257,815,482 | 2018 |
| Star Wars: The Force Awakens | $247,966,675 | 2015 |
| Avengers: Doomsday (market threshold) | Must exceed $360,091,572 | 2026 |
The table exposes the structural problem. The two records above $350 million were set seven years apart, and the third-place film sits $100 million below them. Clearing $360 million is not a matter of being a large hit. It requires landing in the top two openings in cinema history.
Why the Forecasts Disagree So Widely
Doomsday is directed by Anthony and Joe Russo, who also made Infinity War and Endgame, and features Robert Downey Jr. as Doctor Doom. The published projection range is unusually wide:
- Conservative: roughly $230 million to $260 million domestic
- Midpoint: roughly $260 million to $300 million domestic
- Bullish: roughly $400 million to $450 million domestic
That spread straddles the $360 million threshold, which is precisely why the market sits near a coin flip rather than at an extreme. When credible forecasts disagree by $200 million on the exact quantity a contract resolves against, a price in the 40s is the rational output.

The December 18 Collision
Dune: Part Three opens the same day, a pairing fans have labeled “Dunesday.” Reporting suggests Doomsday could outgross it by a ratio between roughly 3.2 to 1 and 4 to 1 on opening weekend. If both films clear $100 million, it would reportedly be the first time two releases opened above that mark on the same weekend.
For the specific market in question, the competitor is a modest negative. Screen and premium-format allocation is finite, and the Infinity Vision auditoriums driving over 70% of Doomsday‘s presales are the same high-capacity venues Dune needs. A December date is also structurally different from Brand New Day‘s July slot: holiday releases historically trade a lower opening weekend for longer multi-week legs, which helps total gross and hurts the single number this contract resolves on.
Context for a Tech and Finance Reader
The franchise economics behind the bet are not in dispute. In October 2026, Avengers: Endgame reclaimed the title of highest-grossing film ever from Avatar, $2.9255 billion to $2.9237 billion, helped by a re-release timed ahead of Doomsday. That re-release, Endgame: Encore, opened to $26 million domestically and $60 million internationally for $86 million worldwide and became the first re-release since The Lion King in 3D in 2011 to top the domestic box office. It then fell about 81% to $4.4 million in its second weekend, a reminder that front-loaded demand and durable demand are different things. Brand New Day, for its part, has grossed about $2.517 billion worldwide and ranks as the third-highest-grossing film of all time.
The transferable lesson is about resolution criteria. This market is a clean case study in how a question’s precise wording, not its sentiment, determines its price. Bullish real-world news and a sub-50% contract price coexist here without contradiction, because the contract asks something stricter than the news answers. The same dynamic appears in markets on NASA mission timelines and in equity-adjacent contracts such as those tracking space-sector valuations, where traders price a narrow threshold while headlines describe a broad trend.
What to Watch Next
- Disney-confirmed domestic presales. Tracker estimates are global and unverified. An official domestic update is the number that actually moves this contract.
- Final presales versus the $150 million benchmark. Whether Doomsday approaches Brand New Day‘s pre-opening total is the most direct read available.
- Formal tracking in late November. Industry tracking typically firms up three to four weeks out, which should compress the current $200 million forecast spread.
- Premium-format screen counts. Infinity Vision allocation relative to Dune: Part Three sets the practical ceiling on opening-weekend capacity.
- Reviews and early word of mouth. These affect legs more than openings, but a poor reception can soften a three-day debut.
Frequently Asked Questions
Does 43% mean Avengers: Doomsday will flop?
No. The market prices one narrow outcome: a domestic opening above $360,091,572. Most published forecasts still put the film among the largest openings ever. A NO resolution is fully consistent with a $300 million opening weekend.
Has Doomsday already broken a record?
Not an opening-weekend record, which cannot be set before the film’s December 18, 2026 release. It has reportedly set advance-sales pace records, though the headline worldwide presales figures remain tracker estimates rather than Disney-confirmed numbers.
Why do other markets show a higher probability?
Because they ask different questions. Contracts on whether Doomsday has the biggest opening weekend of 2026 have traded above 50%, but that only requires beating other 2026 releases, not the all-time record. Comparing the two prices directly is a category error.
What exactly does the market use to resolve?
Box Office Mojo’s reported domestic opening weekend gross, measured against the $360,091,572 threshold.
Can US residents trade this market?
Manifold markets of this kind generally operate with the platform’s internal mana currency rather than cash wagers. Rules vary by platform and jurisdiction, and readers should verify current terms directly with the operator.
The Bottom Line
The Manifold contract sits at 43% as of October 25, 2026, with about 38% of its lifetime volume traded in a single day. The move tracks reporting that Avengers: Doomsday passed $125 million in worldwide presales, though only the $50 million domestic figure is Disney-confirmed. The market is not a referendum on whether the film succeeds. It is a bet on a single number, $360,091,572, that only two films in history have come within $100 million of. Published forecasts span roughly $230 million to $450 million domestic, and until that range narrows, a price near a coin flip is the honest reflection of what is actually known.
