The 34°C outcome carries a 48.5% implied probability heading into July 17. That number climbed nearly twenty points in the last 24 hours alone, which tells you traders are repricing fast based on something real. The market question asks: what will the highest temperature in Chongqing be on July 17? The 34°C outcome trades at 0.49 YES and 0.52 NO. The market resolves at 12:00 UTC+8 on July 17, 2026. Total volume stands at $94,926, with $87,010 of that arriving in the last 24 hours. How the Thirty-Four Degree Contract Works This is a discrete temperature outcome market. YES pays out if Chongqing’s official high temperature on July 17 lands exactly at 34°C. Any other reading, whether 33°C, 35°C, or anything else across the eleven listed outcomes, resolves this contract NO. The resolution source is the market’s designated weather data provider. 34°C YES trades at 0.49, implying a 48.5% probability of an exact match.34°C NO trades at 0.52, implying a 51.5% probability that the day’s high lands somewhere else. A NO outcome here does not mean Chongqing stays cool. It means the peak reading misses 34°C in either direction. July is Chongqing’s most brutal month. The city routinely posts highs in the 36°C to 40°C range during peak summer. A reading at 34°C would actually sit on the lower end of what July typically delivers in this basin city. That is the core tension in this contract: the market is not debating whether it will be hot. It is debating a precise degree. Momentum and Market Signals Sponsored Partner The momentum composite here is unusually strong. A 19.5% price surge in 24 hours combined with a trend score of 59.52 and flat hourly movement suggests traders made a decisive repositioning yesterday and have since held steady. The most likely driver is updated short-range forecast data for July 17 showing surface temperatures converging near the 34°C to 35°C range rather than the 37°C to 39°C readings Chongqing more typically posts in mid-July heat waves. Total volume at $94,926 is modest. The fact that $87,010 arrived in the last 24 hours makes this effectively a new market in terms of price discovery. Liquidity sits at $102,789, which is actually deeper than total volume. That means the order book can absorb further repositioning. Still, with total volume under $100,000, a single large trade can move this price sharply. The market is pricing uncertainty, not science. The 24-hour price surge of 19.5% connected directly to new forecast data narrowing the expected high toward 34°C to 35°C range.Flat 1-hour movement since the surge indicates traders have settled at current pricing pending final forecast confirmation.Liquidity at $102,789 exceeds total volume, keeping the order book functional but thin enough to move on fresh data.The 34°C outcome competes most directly against 35°C and 33°C, which likely absorbed capital flowing out of higher-temperature outcomes.Volume under $100,000 total means this contract carries LOW confidence rating. Price reflects current best estimate, not deep consensus. Lines Analysis: Chongqing’s Forecast Window What supports 34°C landing is a forecast signal that brought traders in hard yesterday. Chongqing sits in the Sichuan Basin, a geography that traps heat and produces sharp daily highs. When regional forecasts show a moderated ridge rather than a full heat dome, readings in the 33°C to 35°C band become plausible. The data doesn’t care about the politics of whether this is a notable heat event. A 34°C high in Chongqing in mid-July is actually a relatively mild day for this city. The case against 34°C landing is straightforward: precision. Even if forecasts point toward the low-to-mid 30s, a one-degree miss in either direction resolves this contract NO. Chongqing’s July highs have historically skewed hotter than forecast models suggest, particularly when the basin holds overnight heat. A reading of 35°C or 36°C is entirely consistent with the same forecast signal that drove yesterday’s price surge. The competing outcomes at 35°C, 33°C, and 36°C are all live contracts drawing real capital. China Meteorological Administration forecast updates for July 17 will be the single most important input before resolution.Any shift in the regional pressure pattern toward a stronger heat dome pushes probability toward 36°C through 39°C outcomes and away from 34°C.Morning temperature readings on July 17 in Chongqing’s urban core will signal whether the day is tracking toward the lower or upper band.Competing outcomes at 33°C and 35°C will absorb capital if forecasts narrow further, compressing the 34°C probability window.Resolution happens at 12:00 on July 17, meaning final positioning closes before the day’s peak heat is even recorded in most time zones. Total volume at $94,926 reflects a market that found its price fast. Here’s what the measurements are telling us: forecasts shifted this contract from 0.28 to 0.49 in roughly 24 hours. That is a strong signal. But the precision requirement means even a well-calibrated forecast leaves meaningful NO probability alive. The data favors 34°C as the modal outcome right now. It does not favor it at 90% confidence. LINES VERDICT NARROW FAVORITE WITH PRECISION RISK Forecasts drove a legitimate repricing toward 34°C, but Chongqing’s basin geography and July’s heat variability mean a one-degree miss remains a real outcome. The 48.5% probability reflects exactly how much uncertainty a precise temperature target carries even when directional forecasts align. What the market says: 48.5% implied probability means traders see 34°C as the single most likely outcome while acknowledging the eleven-outcome field keeps NO firmly alive. Volume is thin enough that the final China Meteorological Administration forecast update before resolution on July 17 could reprice this contract sharply. Key unknown: The July 17 morning forecast update from China Meteorological Administration is the decisive data point. Any shift of one degree in either direction in the predicted high would push capital out of 34°C and into neighboring outcome contracts within hours of publication. Frequently Asked QuestionsWhat does 48.5% probability mean for the 34°C outcome?It means traders currently see a 48.5% chance that Chongqing's official high lands exactly at 34°C on July 17. All other temperature outcomes collectively hold the remaining 51.5% probability.How does the NO contract pay out here?NO pays out if Chongqing's high on July 17 is anything other than 34°C. That includes 33°C, 35°C, or any other listed outcome. A one-degree miss in either direction resolves NO.What data would move this market before resolution?A China Meteorological Administration forecast update shifting the predicted high by one degree would reprice this contract sharply. Morning temperature readings on July 17 are also a real-time signal.When does this market resolve?The market resolves at 12:00 on July 17, 2026. Final positioning closes at that time, before the full day's heat peak is confirmed in many time zones.Is volume deep enough to trust this price?Total volume is $94,926 with $87,010 arriving in 24 hours. That is LOW confidence by volume thresholds. Thin markets can reprice sharply on a single new forecast or large trade.How is the Smart Money Index calculated?We aggregate the live positions of the top 50 Polymarket whales (ranked by 30-day tracked volume) into one composite reading per market.

Forecast Locks In at 34°C The China Meteorological Administration issues a July 17 forecast pinning Chongqing's high at 34°C with low variance. Traders rotate capital from 35°C and 36°C outcomes into 34°C, pushing the YES price above 0.60. Morning readings on July 17 confirm the city is tracking below its typical July baseline, reinforcing the forecast signal. Basin Heat Pushes High to 36°C or Above Chongqing's Sichuan Basin retains overnight heat and the July 17 high overshoots forecast models, landing at 36°C or 37°C. The 34°C YES price collapses back toward 0.20 as capital shifts to higher-temperature outcomes. This scenario is historically consistent with mid-July basin behavior even when short-range models suggest moderation. 33°C Reading Keeps NO Alive A cooler-than-expected regional air mass pushes Chongqing's high to 33°C, resolving the 34°C contract NO but paying out the 33°C outcome. Traders holding NO on 34°C collect regardless of which lower outcome wins. This scenario requires a genuine break in the heat pattern, not just a small forecast miss. Afternoon Thunderstorm Cuts the High A convective thunderstorm develops over Chongqing during the afternoon of July 17 and suppresses the day's maximum temperature below forecast. This is a real wildcard in basin climates during summer. Depending on storm timing and intensity, the high could land anywhere from 31°C to 34°C, scrambling probability across multiple outcome contracts simultaneously. Key macro factor: Chongqing's July temperature anomalies correlate with Western Pacific subtropical high pressure positioning, which La Nina or El Nino transitions can shift by two to three degrees over a single week.
