Polymarket
This market tracks the highest temperature recorded in Chongqing on May 30, 2026. On Polymarket, the leading outcome—a high of 27°C—stands at 27.5%, while a high of 28°C carries 22.5% probability. Resolution will be determined by historical weather data from Weather Underground, specifically measurements from Chongqing Jiangbei International Airport Station. Watch the actual temperature reading on May 30, 2026, as that date will trigger final settlement.
Prediction market odds on Polymarket reflect real-time aggregated trader beliefs about Chongqing's maximum temperature on May 30, often incorporating meteorological data faster than traditional analyst forecasts. While weather analysts rely on numerical models and historical patterns, prediction markets price in collective intelligence from participants with financial incentives to be accurate. Market odds tend to converge toward consensus when multiple independent forecasters align, but may diverge when new satellite imagery, atmospheric pressure changes, or seasonal anomalies emerge. Comparing Polymarket probabilities to published meteorological agency forecasts can reveal where traders see edge or disagreement with official predictions.
The market resolves at May 30, 2026, after the highest temperature in Chongqing on May 30 has been recorded and verified. Resolution hinges on the official maximum temperature reading for that calendar day in Chongqing, typically sourced from national meteorological authorities or designated weather stations. The specific outcome contract that matches the recorded temperature will be marked correct, and all other temperature-range contracts will resolve to zero. Traders should monitor official weather data releases and any clarifications from the market operator regarding which data source or station will be used as the authoritative reference for settlement.
Major weather systems, monsoon onset timing, and upper-atmosphere pressure patterns will significantly influence odds for Chongqing's May 30 high temperature. Early-season heat waves, tropical cyclone activity, or sudden cold fronts can shift probabilities sharply. Updated seasonal forecasts from meteorological agencies, real-time satellite imagery showing cloud cover and moisture, and historical May temperature anomalies will attract trader attention. As May 30 approaches, short-range weather models become more reliable, typically narrowing the range of plausible outcomes. Local air quality reports and urban heat island effects may also factor into trader positioning. Breaking news about climate patterns or regional weather events will likely trigger rapid repricing on Polymarket.
