Wuhan May 11 Temperature: Will It Hit 31°C?

The market has already decided. Traders on this contract have priced the 31°C outcome at 99.6% probability, and the price movement over the past 24 hours tells you exactly how that conviction built. This is not a market pricing uncertainty. This is a market that has seen enough data to treat the question as settled.

Wuhan sits in central China’s Yangtze River basin, where May temperatures can swing sharply between cool overcast days and warm, humid afternoons driven by southerly airflow. The question here is precise: does the highest recorded temperature on May 11 land specifically at 31°C? Not 30°C, not 32°C. Exactly 31°C. That precision is what made this contract interesting earlier in the week, and it is what made the last 24 hours so decisive.

How the 31°C Contract Works

This market resolves YES if official weather data confirms 31°C as the highest temperature recorded in Wuhan on May 11, 2026. Resolution occurs at 2026-05-11 12:00:00. The full ladder of outcomes runs from 24°C or below through 34°C or higher, with each degree as a separate contract.

• YES (31°C): Price 1.00, implied probability 99.6%.
• NO (any other outcome): Price 0.00, implied probability 0.4%.

A NO payout requires the actual high to land on any other rung of the ladder: 30°C, 32°C, or any other value. Official temperature readings from China Meteorological Administration stations in Wuhan determine which outcome resolves. A reading of 30.9°C or 31.1°C would shift resolution to a neighboring contract. That half-degree gap on either side is the only realistic path to NO at this stage.

Momentum and Market Signals

The combined momentum signal here is striking. A 66.1% price gain over 24 hours, a 22.6% move in the last hour, and a trend score of 87.94 all point to the same driver: actual May 11 temperature data coming into alignment with the 31°C threshold. When a daily-high contract moves like this, it is almost always because observed conditions or intraday readings are confirming the outcome in real time.

Total volume stands at $38,400, with $28,376 of that trading in the last 24 hours. Liquidity sits at $13,027. Volume is below $1 million, which means this market can move sharply on even a small data update or a corrected weather reading. Thin liquidity is normal for hyper-specific daily temperature contracts. It does not undermine the signal, but it does mean price can gap quickly if conditions shift before the resolution timestamp.

• 1h change (+22.6%): Intraday readings in Wuhan are tracking at or near 31°C, pulling late capital into the YES contract.
• 24h change (+66.1%): Forecast models updated May 10 pointed to a warm but not extreme day, consistent with a 31°C high rather than 32°C or higher.
• Trend score 87.94: Reflects strong directional conviction from traders who have access to near-real-time weather data for Wuhan.
• $28,376 in 24h volume: The majority of total market capital moved in the last day, confirming this is a late-stage convergence, not early speculation.
• Open interest at $0: No unresolved positions remain on the books. Settlement is effectively in progress.

Lines Analysis: What the Data Is Saying

Here’s what the measurements are telling us. Wuhan in mid-May sits in a transitional weather pattern. Daytime highs in the 28°C to 33°C range are typical, with 31°C representing the lower-middle of a warm spring day rather than an extreme. China Meteorological Administration surface stations in Wuhan record and publish daily maximum temperatures with high reliability. The fact that traders have pushed this contract to near-certainty suggests observed or near-final data supports exactly 31°C.

The risk that keeps NO from being completely dead is measurement precision. Official temperature records in China use standard shelter readings at 1.5 meters, and daily maximums are published after the observation window closes. If the true maximum lands at 31.4°C and rounds to 31°C under the resolution methodology, YES wins. If it lands at 31.6°C and rounds to 32°C, the neighboring contract collects. That rounding boundary is the only credible scenario where this contract reprices before 2026-05-11 12:00:00.

Signals to monitor before resolution:

• China Meteorological Administration Wuhan station data published after 12:00 local time will be the definitive resolution input.
• Any correction to intraday temperature reporting from Wuhan Tianhe or central urban stations would directly affect the outcome.
• Regional weather systems moving through Hubei province before noon could push the high slightly above or below 31°C.
• Neighboring temperature contracts (30°C and 32°C) showing any late price movement would signal that traders are hedging against rounding uncertainty.

The data favors YES. The $38,400 in total volume, concentrated in the last 24 hours, reflects traders who have tracked the Wuhan forecast closely and are betting on confirmation, not speculation. The data doesn’t care about the politics of how this contract was structured. It cares about one number from one weather station on one afternoon.

LINES VERDICT

Wuhan Hits Thirty-One

The market has converged on 31°C with the kind of late-stage momentum that typically reflects observed data, not forecast confidence. Every signal points to confirmation before the resolution window closes.

What the market says: At 99.6%, traders have priced this as effectively settled. The only remaining volatility risk is a rounding boundary in official temperature reporting before the 2026-05-11 12:00:00 resolution timestamp.

Key unknown: The single event that could reprice this contract is a final official reading from China Meteorological Administration that places the Wuhan daily maximum above 31.5°C or below 30.5°C, shifting resolution to the 32°C or 30°C contract instead.

Scientific Context: Wuhan in May

Wuhan’s climate in May is shaped by its inland position in the middle Yangtze basin, where warm continental air masses from the north collide with moisture from the south. Historical May daily highs in Wuhan average between 26°C and 30°C in early May, rising toward 28°C to 33°C by mid-month. A 31°C high on May 11 sits squarely within the climatological envelope for this date. It is neither a record nor an anomaly. That normalcy is part of why the market converged so cleanly: the forecast was unremarkable, which made precision easier.

The market is pricing uncertainty, not science, but in this case the uncertainty has nearly resolved. Temperature measurement in China follows World Meteorological Organization standards. China Meteorological Administration data is considered reliable for prediction market resolution purposes. Any event that could move this contract before 2026-05-11 12:00:00 would have to involve a last-minute correction to observed station data or an unexpected convective event that pushed afternoon temperatures above or below the 31°C band.

Frequently Asked Questions

• What does 99.6% probability mean here? It means traders collectively assign a 1-in-250 chance that the Wuhan daily high on May 11 lands on any outcome other than 31°C. That is near-certainty, not absolute certainty.
• How does the NO contract pay out? The NO contract on the 31°C outcome wins if China Meteorological Administration data shows a Wuhan daily maximum of 30°C, 32°C, or any other temperature on the ladder for May 11.
• What single event would move this price? A corrected or finalized official temperature reading from Wuhan that places the May 11 high above 31.5°C or below 30.5°C would immediately shift capital to a neighboring contract.
• When does this contract resolve? Resolution is set for 2026-05-11 12:00:00, aligned with the close of the observation window for the Wuhan daily maximum temperature.
• Is volume reliable here? Total volume of $38,400 is well below $1 million, which means liquidity is thin. Price can gap sharply on a single updated data point. The signal is directionally strong but not deep-market confirmed.

This analysis reflects market conditions as of 2026-05-11 03:10:25.
