NO at 61% implied probability

FRAGMENTED FIELD, THIRTY-NINE LEADS NARROWLY: The 39°C contract holds the highest single-outcome probability in a multi-outcome market, but thin liquidity and Chengdu's afternoon weather variability keep NO firmly in control. Market probability: 36%.

Chengdu is baking. The Sichuan Basin city sits in a geography that traps summer heat, and July 24 is shaping up as a genuine coin-flip for anyone trading the 39°C outcome. The market currently prices that exact temperature at 36%. That means traders see more paths to a different reading than to 39°C landing precisely.

The market question asks: what is the highest temperature in Chengdu on July 24, 2026? The 39°C contract trades at 0.36 YES versus 0.64 NO. The market closes at noon local time on July 24. Total volume stands at $54,469, with $43,388 of that arriving in the last 24 hours.

How the Thirty-Nine Degree Contract Works

This market resolves on a single daily maximum temperature reading for Chengdu on July 24. One body determines resolution. The contract pays out only if the verified high lands exactly at 39°C, not above or below.

  • YES (39°C) trades at 0.36, implying a 36% probability the high lands precisely there.
  • NO trades at 0.64, covering every other outcome: 38°C, 40°C, 37°C, 41°C, or any reading that is not 39°C.

The NO contract pays when Chengdu’s July 24 high misses 39°C in either direction. A reading of 40°C or 41°C is just as much a loss for YES holders as a reading of 37°C. The Sichuan Basin tends to push temperatures into the upper 30s through July, but the difference between 38°C and 40°C on any given afternoon is the difference between a storm cell rolling in from the west or clear skies holding through the afternoon peak.

Momentum and Market Signals

The composite momentum signal is mildly positive. The 39°C contract gained 1.0% in the last hour and 3.5% over the last 24 hours, with a trend score of 42.09. That combination suggests the market is drifting upward, likely reflecting incoming short-range forecast data pointing toward high-30s heat rather than a sub-37°C or over-41°C outcome.

Total volume at $54,469 is thin. The last 24 hours account for roughly 80% of all activity, which tells us this market came alive only recently. Liquidity sits at $17,443. At this depth, a single large trade can move the price sharply before resolution tomorrow. Treat the 36% probability as directionally useful, not precise.

  • The 39°C contract gained 3.5% in 24 hours, consistent with forecast data tightening around the upper-30s range.
  • The 1h change of +1.0% adds to that picture: traders are edging toward 39°C as the most likely single outcome, not running from it.
  • Volume of $43,388 in 24 hours is high relative to total volume, signaling fresh information entered the market recently.
  • Liquidity at $17,443 means thin order books. New data or a weather model update could gap the price before noon on July 24.
  • Trader sentiment leans bearish at 64% NO, consistent with the inherent fragmentation of a multi-outcome market.

Lines Analysis: Chengdu Temperature on July Twenty-Four

The data doesn’t care about the politics, and here it is telling us something specific: 39°C is the single most likely outcome on the board, but it is not the most likely outcome in absolute terms. Chengdu’s July average highs cluster between 33°C and 36°C in normal years, but the city regularly spikes into the 38-40°C band during heat events. The current upward drift in the contract suggests short-range models are converging on the upper-30s zone. If the afternoon peak holds near 39°C without breaching 40°C, YES resolves.

What makes NO real is the temperature distribution itself. A reading of 40°C or higher is entirely plausible if the heat dome strengthens or if afternoon convection suppresses before the day’s peak. A reading of 38°C or lower is equally plausible if an isolated storm cell clips the city before 3 p.m. The Sichuan Basin’s topography accelerates local afternoon variability. Either of those outcomes collapses the YES contract to zero regardless of how close the forecast sits to 39°C.

  • China Meteorological Administration short-range forecasts for Chengdu on July 24 will be the single most important repricing trigger between now and close.
  • Any mesoscale convective system developing over the western Sichuan Basin before midday would push the temperature peak below 39°C.
  • Clear skies and sustained southwesterly flow through the afternoon would favor the 39-40°C band, keeping the YES contract competitive.
  • A model shift toward 40°C or above would redirect volume to the 40°C contract and drain the 39°C side.
  • Resolution at noon Chengdu time compresses the window. The daily maximum typically occurs between 2 and 4 p.m., so noon resolution may capture the late-morning reading, not the true daily peak.

Here’s what the measurements are telling us: the market is pricing uncertainty, not science. At $54,469 total volume, this is a thin contract with real price sensitivity to the next weather model run. The 36% probability for 39°C is the highest single-outcome probability on the board, but the NO side at 64% correctly reflects how many ways this can resolve differently. The data favors continued upward drift in the 39°C contract only if afternoon forecast models keep the high pinned below 40°C.

LINES VERDICT

FRAGMENTED FIELD, THIRTY-NINE LEADS NARROWLY

The 39°C outcome holds the highest individual probability in a crowded field, but thin liquidity and Chengdu’s afternoon variability keep the NO side firmly in control.

What the market says: At 36% implied probability, traders see 39°C as the most likely single outcome but far from certain. Thin liquidity means the price can shift sharply on any model update before noon on July 24.

Key unknown: The China Meteorological Administration’s next short-range forecast for Chengdu on July 24 is the single most important data point. A model shift of even one degree either way would reprice the 39°C contract significantly before close.

Frequently Asked Questions

It means the market estimates a roughly one-in-three chance Chengdu's July 24 high lands exactly at 39°C. All other temperature outcomes combined account for 64% of the probability.

NO pays when Chengdu's verified July 24 high is any temperature other than 39°C. That includes readings of 38°C, 40°C, or anything else on the board.

A China Meteorological Administration short-range forecast update placing the July 24 Chengdu high firmly at 39°C would push the YES price higher. A shift toward 40°C or a storm alert would drain it.

The market resolves at noon on July 24, 2026. Note that Chengdu's daily maximum temperature typically occurs between 2 and 4 p.m., so resolution captures the late-morning reading.

Thin volume means the price is directionally useful but imprecise. Liquidity of $17,443 means a single large trade can gap the price significantly before the market closes tomorrow.

We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market. It refreshes every hour.

What Could Shift These Probabilities?

Forecast Locks In Thirty-Nine

China Meteorological Administration model runs for July 24 converge on a Chengdu high of exactly 39°C, with clear skies and light winds through late morning. Traders pile into the 39°C contract as the most likely single outcome, pushing it above 45%. The thin order book amplifies the move.

Heat Pushes Past Forty

A strengthening heat dome over the Sichuan Basin drives the afternoon high to 40°C or above before noon. The 39°C contract collapses as volume shifts to the 40°C and 41°C outcomes. Traders who bought YES at 0.36 lose their full stake regardless of how close the final reading lands.

Storm Cell Keeps It Below Thirty-Eight

A mesoscale convective system moving through western Sichuan brings cloud cover and cooling before the morning peak. The high stalls at 37°C or 38°C. The 39°C contract resolves NO, and lower-temperature outcome contracts capture the volume. The market mispriced the convective risk in the short window before close.

Noon Resolution Catches the Actual Peak Early

An unusual early-afternoon heat spike pushes Chengdu to 39°C before the noon resolution cutoff, resolving YES cleanly despite later cooling. This scenario rewards traders who recognized the noon resolution window as capturing peak heat on a specific synoptic pattern, not just the historical afternoon norm.

Key macro factor: The 2026 Western Pacific heat pattern, influenced by a weakening La Nina transitioning toward neutral ENSO conditions, is sustaining above-average surface temperatures across the Sichuan Basin through late July.
