Superconductor Bet Heats Up: Manifold Traders Give a Room-Temperature Breakthrough 15% Odds Before 2031. A long-dated Manifold contract asking whether the world will get a room-temperature superconductor before 2031 saw roughly 42% of its all-time volume trade in a single day, even as the price sits near 15% implied probability of YES. The sudden activity is not tied to one confirmed breakthrough in the past two weeks, but to a run of 2026 laboratory results and a coordinated research push that has traders repricing a science story that never fully cooled after the 2023 LK-99 frenzy.

What the Manifold market is asking
The contract in question is “Will we get room temperature superconductors before 2031?” on Manifold, a play-money prediction platform where users trade on the probability of future events. Manifold contracts resolve YES or NO based on a stated criterion, and prices move as traders buy shares on either side. The price of a YES share, expressed as a percentage, is read as the market’s implied probability that the event happens.
Because Manifold uses play-money mana rather than cash, its prices are not a financial signal in the way a regulated exchange quote is. They are better read as a crowd-sourced forecast. For a question as technical and long-dated as room-temperature superconductivity, that crowd skews toward physics-literate traders, which is part of why sharp moves in the volume draw attention. If you are new to how these venues price a claim, our explainer on the mechanics behind Manifold science markets covers the basics.
The odds as of September 11, 2026
As of September 11, 2026, the market showed a 15% implied probability of YES, according to Manifold. The notable event was flow, not price: about 42% of the contract’s all-time volume changed hands in the prior 24 hours. That combination, heavy trading with a price that stayed low, tells you traders were actively debating the question but did not, on balance, conclude a breakthrough had become materially more likely before 2031.
A 15% reading implies the crowd sees roughly one-in-seven odds of a validated result inside the window. For context on how to translate a percentage price into a forecast, and its limits, see our note on reading long-dated Manifold science odds.
What is actually driving the money
Based on available reporting, there was no verified new claim of a room-temperature, ambient-pressure superconductor in the one to two weeks before September 11, 2026. No preprint or press release in that window met the field’s validation bar, and none was prominently reported alongside the year’s established records. The most-supported explanation for the volume spike is renewed attention to a cluster of 2026 advances plus a formal research agenda, rather than a single step-change event.
That cluster has three parts: a new ambient-pressure temperature record set in March 2026, an artificial-intelligence-guided discovery method published in mid-2026, and a multi-institution roadmap arguing that room-temperature superconductivity is a materials and engineering problem, not a violation of physics. Each is incremental, but together they gave traders fresh reasons to revisit a dormant contract. When several traders re-enter at once, volume can spike even if the consensus price barely moves.
The 151 K ambient-pressure record
In March 2026, physicists at the University of Houston reported an ambient-pressure transition temperature of 151 Kelvin, about minus 122 degrees Celsius, in the mercury-based copper-oxide ceramic known as Hg-1223. The work by Ching-Wu Chu and Liangzi Deng was published in the Proceedings of the National Academy of Sciences on March 9, 2026, and broke a record that had stood since Hg-1223 was found to superconduct at roughly 133 K in 1993.
The team used a technique called pressure quenching. The material was compressed in a diamond anvil cell to around 300,000 times normal atmospheric pressure, then the pressure was released quickly, leaving the sample in a higher-temperature superconducting state at ambient pressure for up to two weeks. The result lifts the ambient-pressure ceiling by about 18 degrees. It is a genuine record, and it is still roughly 150 degrees short of room temperature near 300 K, which is the gap that keeps the Manifold price low.
AI enters the search
In mid-2026, an international team led by Professor Paivi Torma of Aalto University reported using machine learning combined with quantum-physics calculations to identify and then experimentally confirm two previously unknown superconductors, YRu3B2 and LuRu3B2. Rice University collaborators synthesized and tested the candidates that the models flagged. The Aalto group frames the method as a way to screen a chemical space that is effectively unlimited, potentially processing billions of candidate materials.
The team belongs to the SuperC consortium, formed in 2023 and described as the first coordinated global collaboration aimed at finding a room-temperature superconductor. Its stated target is 2033. That target date sits after the 2031 cutoff in the Manifold contract, which is one concrete reason a well-informed trader might hold the price near 15% rather than higher: the field’s own flagship effort is not promising success before the window closes.
Why “before 2031” is a high bar
The community has converged on a demanding checklist for any credible room-temperature, ambient-pressure claim. Reporting on the 2026 landscape lists five criteria: zero resistance above 273 K measured with a four-probe setup, a clear Meissner effect confirmed by SQUID magnetometry, a specific-heat anomaly at the transition temperature, independent replication by at least three groups within six months, and stability at 1 atmosphere for at least 24 hours. As of 2026, no material has satisfied all five.
The distinction between pressure regimes matters here. Hydride superconductors such as lanthanum hydride reach near room-temperature behavior, but only at pressures in the range of 170 to 200 gigapascals, which is close to the pressures found deep inside the Earth and useless for wires or magnets. At ambient pressure, the verified ceiling is the 151 K Hg-1223 result. A YES on this market requires closing a large temperature gap at usable pressure and then clearing the full validation checklist, all before 2031. That is why heavy trading did not push the price up.
The credibility overhang from LK-99 and a retraction
Two recent episodes shape how traders weight fresh claims. In 2023, a South Korean group’s preprint on a material called LK-99 went viral as a claimed room-temperature, ambient-pressure superconductor. It was not one. Multiple groups failed to reproduce superconductivity, and later analysis traced the anomalous signals to copper-sulfide impurity phases in the samples rather than to superconductivity.
Separately, a high-profile 2020 report of a carbonaceous sulfur hydride superconducting near 287 K, at very high pressure, was retracted by Nature in 2022 amid data-integrity concerns, and subsequent claims from the same group were treated cautiously by the field. Together these cases taught prediction-market participants to discount single-group, unreplicated announcements heavily. It is a direct reason the market barely moved on renewed 2026 attention: traders now wait for independent replication before repricing, a pattern also visible in other long-dated science contracts like the Millennium Prize problem markets.
Timeline of key superconductivity milestones
| Date | Milestone | Approx. Tc | Pressure |
|---|---|---|---|
| 1911 | Superconductivity discovered (mercury) | ~4 K | Ambient |
| 1993 | Hg-1223 cuprate record | ~133 K | Ambient |
| 2020 | Carbonaceous sulfur hydride (retracted 2022) | ~287 K | ~267 GPa |
| 2023 | LK-99 claim (later discredited) | Claimed ~300 K | Ambient (claimed) |
| 2025 | (La,Pr)3Ni2O7 nickelate films, onset above 40 K | ~40 to 63 K | Ambient |
| Mar 2026 | Hg-1223 via pressure quench (University of Houston) | 151 K | Ambient |
| Mid 2026 | AI-guided discovery, YRu3B2 and LuRu3B2 (SuperC) | Low-temperature | Ambient |
The table makes the trader’s dilemma visible. Ambient-pressure records are climbing, but slowly, and the only near-room-temperature results sit at impractical pressures. Room temperature is near 300 K.
Broader context for a tech and finance reader
Room-temperature, ambient-pressure superconductors would matter far beyond physics. They would cut losses in power transmission, shrink and cheapen MRI machines, and lower the cost of the strong magnets used in fusion research and maglev transport. That commercial upside is exactly why the topic recurs on prediction markets and why volume can surge on incremental news. The gap between the science story and the near-term probability is where the market does its work.
Prediction markets have become a fast way for readers to gauge crowd sentiment on binary questions, from science to policy. The same logic that prices this superconductor contract also drives markets on rate decisions, such as the Federal Reserve September 2026 rate odds, and on policy outcomes like Kalshi’s government spending contracts. In each case the price is a forecast, not a fact.
What to watch next
Three signals would justify a real repricing of this contract. First, an ambient-pressure result that pushes the transition temperature meaningfully above the current 151 K record and survives peer review. Second, any claim near 273 K at ambient pressure that clears the four-probe, Meissner, and specific-heat tests and, critically, gets independently replicated by multiple groups inside six months. Third, progress from AI-guided screening efforts like SuperC that turns candidate lists into confirmed high-temperature materials rather than proofs of concept.
Absent one of those, the base case is a market that trades actively on headlines while holding a low price. A 15% reading with a 2031 deadline reflects a field that most experts view as physically possible but not close, against a research roadmap that itself targets 2033.
Frequently asked questions
Does the 42% volume spike mean a breakthrough happened? No. Volume measures trading activity, not the outcome. The price stayed near 15%, which indicates traders debated the question heavily but did not conclude a validated breakthrough had become likely before 2031.
Is the 151 K University of Houston result a room-temperature superconductor? No. At 151 K, or about minus 122 degrees Celsius, it is a record for ambient pressure but still roughly 150 degrees below room temperature near 300 K.
Why do traders discount dramatic new claims? Because of recent history. LK-99 in 2023 was not reproducible and its signals were later attributed to impurities, and a 2020 hydride paper was retracted in 2022. Traders now wait for independent replication before repricing.
Are Manifold prices real money? No. Manifold uses play-money mana, so its prices are a crowd forecast rather than a regulated financial quote. Kalshi, by contrast, is a CFTC-regulated US exchange that uses real money.
