Intro

This market tracks whether Beijing's highest temperature will reach 37°C on May 30, 2026. On Polymarket, the leading outcome—a high of exactly 37°C—stands at 29.5%, while a high of 36°C carries 25.5% probability. Resolution will be determined by historical temperature data from Wunderground, using readings from Beijing Capital International Airport Station. Watch the actual weather conditions as May 30, 2026 approaches to assess whether seasonal heat patterns will push temperatures to these threshold levels.

Frequently asked questions

Prediction market odds reflect real-time trader expectations and often incorporate meteorological forecasts faster than traditional analyst reports. While weather agencies and climate analysts publish seasonal or medium-range outlooks for Beijing in late May, prediction markets aggregate diverse participant views into a single probability. Market odds tend to be more dynamic and responsive to breaking weather patterns, model updates, and atmospheric conditions. Comparing market-implied probabilities to official forecasts from China's meteorological authority can reveal whether traders are pricing in more optimistic or pessimistic temperature scenarios than institutional predictions.

The market resolves on May 30, 2026. Resolution is determined by the official highest temperature recorded in Beijing on May 30, measured according to standard meteorological protocols. The outcome depends on which temperature bracket or threshold the actual daily high falls into, as defined by the specific contract terms. Once the day concludes and official temperature data is published by China's meteorological authorities, the market settles automatically based on the recorded value. Traders should verify the exact resolution criteria and data source specified in the market terms before placing positions.

Several factors could shift market odds before resolution. Major weather pattern changes, such as shifts in monsoon timing or unexpected cold fronts, would alter trader expectations. Updated seasonal forecasts from meteorological agencies and high-resolution weather models released closer to May 30 typically drive repricing. Urban heat island effects, pollution levels, and cloud cover on the day itself influence actual temperatures. Broader climate anomalies, El Niño or La Niña conditions, and atmospheric circulation patterns also matter. As the event date nears, real-time weather observations and intraday forecasts become increasingly important price drivers, with traders adjusting positions based on the most current data available.
