The 22°C outcome for Wuhan’s highest temperature on June 8 is sitting at a 95.5% implied probability. That’s not a market pricing uncertainty. That’s a market pricing settled meteorological reality, with a few dollars left on the table for anyone who wants to bet against the thermometer.

The question is simple: will Wuhan’s peak temperature on June 8, 2026 reach exactly 22°C? The YES contract trades at $0.96, the NO contract at $0.05, and the market resolves at 12:00 UTC on June 8. Total volume is $43,957.

How the 22°C Contract Works

This market resolves YES if Wuhan’s recorded daily high on June 8 hits exactly 22°C, as determined by the resolution source. Every other temperature outcome, from 16°C or below up through 26°C or higher, resolves this contract NO.

  • YES ($0.96, ~95.5% probability): Wuhan’s June 8 high is recorded at exactly 22°C.
  • NO ($0.05, ~4.5% probability): Wuhan’s June 8 high lands at any other temperature, including 21°C, 23°C, or outside the stated range.

The NO scenario here is not about cold snaps or heat waves. A single degree in either direction, 21°C or 23°C, is enough to void this contract. That’s the narrow gate the market has already decided won’t open.

Momentum and Market Signals

The momentum signal here is about as clean as it gets. The 22°C contract gained roughly 39% in the 24 hours leading into June 8, with a trend score of 64.60. That kind of move happens when forecast data locks in and remaining uncertainty collapses. Weather models converging on a specific reading in the final 24 to 36 hours before resolution is the most likely driver.

Total volume stands at $43,957, with $38,540 of that trading in the last 24 hours. Liquidity sits at $70,359. Volume is well below $1 million, which means this contract can reprice sharply on any updated forecast data. The order book is not deep enough to absorb a surprise without moving the needle fast.

  • The 24h price change of +39.0% and trend score of 64.60 together signal a sharp convergence event, most likely tied to short-range forecast confirmation in the final trading window.
  • The 1h change of +0.0% indicates the market has stopped moving. Traders have already positioned.
  • Liquidity of $70,359 exceeds total volume, which means the order book is relatively well-stocked for a market this size.
  • The NO side at $0.05 is priced like a longshot, not a genuine two-sided market.

Lines Analysis: Reading the Wuhan Thermometer

Here’s what the measurements are telling us. Early June in Wuhan typically sits in the transitional zone between spring and the onset of summer heat. Average daily highs in Wuhan for early June historically run in the low to mid-twenties Celsius. A reading of exactly 22°C is plausible and consistent with regional climatology for this period.

What makes the NO side real is precision. This market doesn’t resolve on a range. It resolves on a single integer. Short-range forecast models can place a high with confidence in a narrow band, but the difference between a 21.5°C and a 22.5°C reading, after rounding, is the entire contract. A late afternoon wind shift, an unexpected cloud band, or a slightly warmer boundary layer could push the reading to 23°C. That’s all it takes.

  • Short-range NWP models (GFS, ECMWF) converging on 22°C in their final runs would explain the 39% price jump and are the primary signal to monitor.
  • Any model divergence in the final 6-hour forecast window could revive NO contract interest briefly.
  • The resolution source’s rounding methodology matters. A reading of 22.4°C rounds down; 22.5°C rounds up. That precision is baked into the remaining 4.5% NO probability.
  • Related markets (hottest years, earthquake counts) show no correlation to this contract. Wuhan’s June 8 high is a purely local meteorological question.

The data doesn’t care about the politics, and in this case, there aren’t any. The total volume of $43,957 is modest, but the concentration of that volume in the last 24 hours tells a clear story: traders with access to updated forecast data moved hard into YES when the models locked in. The market is pricing near-certainty, not scientific uncertainty.

LINES VERDICT

Forecast Confirmed

The 39% single-day price surge into a 95.5% implied probability reflects forecast convergence, not speculation. Short-range models appear to have settled on 22°C for Wuhan’s June 8 peak, and the market has responded accordingly.

What the market says: At 95.5% implied probability, traders have effectively closed the book on alternative outcomes. With resolution set for June 8 at 12:00 UTC, there is almost no trading window left for this contract to reprice. The thin total volume means any late forecast shift could still move the price sharply, but the window is narrow.

Key unknown: The single factor that could reprice this contract is a final-hour model update showing the Wuhan high shifting to 21°C or 23°C before the resolution cutoff. At this point, that risk is priced at 4.5%.

Scientific and Meteorological Context

Wuhan sits in central China’s Yangtze River basin, a region with well-documented temperature variability in early June. The city transitions from spring to summer during this window, with daily highs fluctuating as synoptic-scale weather systems move through. Early June highs in the low twenties are climatologically normal. The market’s convergence on 22°C reflects both forecast confidence and the seasonal baseline.

The related market asking where 2026 will rank among the hottest years on record sits at 61%. That broader climate context doesn’t directly affect a single-city daily high, but it does suggest the broader atmospheric pattern in 2026 leans warm. A 22°C June 8 high in Wuhan would be entirely consistent with that pattern.

What would move price before June 8 resolution: Nothing is likely to move this contract materially. The resolution window is hours away, volume has already concentrated, and the order book favors YES at near-maximum confidence.

Frequently Asked Questions

It means traders assign roughly a 1-in-20 chance that Wuhan’s June 8 high lands anywhere other than exactly 22°C. At $0.96 per share, the YES contract pays about $0.04 profit if correct.

The NO contract at $0.05 pays out if Wuhan’s recorded high on June 8 is anything other than exactly 22°C, including 21°C or 23°C. That’s a narrow but real window.

A short-range forecast update showing the Wuhan peak shifting to 21°C or 23°C is the only realistic repricing trigger. At this stage, that window is measured in hours, not days.

The market resolves on June 8, 2026 at 12:00 UTC, based on the official recorded daily high temperature for Wuhan.

Total volume of $43,957 is below $1 million, which flags this as a thin market. Liquidity at $70,359 is adequate relative to volume, but a concentrated trade could still move the price noticeably before resolution.

Resolution Analysis

Models Hold at 22C

Short-range NWP models maintain their 22C consensus for Wuhan through the final forecast runs before the 12:00 UTC resolution cutoff. The YES contract drifts toward $0.98 or higher as the last remaining uncertainty collapses. Thin liquidity means even a small volume of confirming trades pushes the price to its ceiling.

Late Model Shift to 23C

A final-hour forecast update from GFS or ECMWF places the Wuhan peak at 23C, driven by a slightly warmer afternoon boundary layer or delayed synoptic system passage. The NO contract reprices sharply from $0.05 toward $0.20 or higher. Thin total volume amplifies any move.

21C Reading Surfaces

A cooler-than-expected cloud band or wind shift pushes Wuhan's observed high to 21C, landing below the target. The 21C outcome contract captures resolution value instead. The NO side of the 22C contract pays out at $1.00, rewarding the 4.5% minority that held through the convergence event.

Rounding Methodology Dispute

The resolution source records a temperature of exactly 22.5C, triggering ambiguity about whether the official reported high rounds to 22C or 23C. Resolution delay or adjudication would create a brief window of extreme price volatility in both the 22C and 23C contracts. This scenario is unlikely but not zero-probability given the integer-precision structure of the market.

Key macro factor: The broader 2026 global temperature context, reflected in related markets pricing a 61% chance that 2026 ranks among the hottest years on record, is consistent with a warm early June baseline in central China, but does not directly determine a single-city daily high.
