Frequently asked questions

Prediction market odds on Polymarket reflect real-time consensus from active traders betting on Shanghai's lowest temperature on May 30. Unlike traditional analyst forecasts, which rely on meteorological models and historical data, prediction markets incorporate dynamic information and financial incentives. Traders continuously update prices based on weather patterns, seasonal trends, and emerging atmospheric data. This crowd-sourced approach often captures shifts in weather expectations faster than static forecasts, though both methods provide valuable perspectives on the likely temperature range.

The market resolves on May 30, 2026, after the lowest temperature in Shanghai on May 30 has been recorded. Resolution is determined by official temperature data for that date. Traders should monitor weather reports and official meteorological records as the event date approaches to understand how outcomes will be verified. The specific temperature threshold or range that determines each outcome is defined in the market's terms, so review those details carefully before trading to ensure your position aligns with your weather expectations.

Several factors could shift odds for Shanghai's May 30 low temperature. Major weather pattern changes, such as shifts in monsoon timing or unexpected cold fronts, typically move prices significantly. Long-range weather forecasts and seasonal climate outlooks released closer to May will influence trader positioning. Urban heat island effects and local pollution levels can also impact minimum temperatures. Additionally, any unusual atmospheric conditions or tropical cyclone activity in the region could trigger rapid repricing. Traders should monitor meteorological updates and seasonal forecasts regularly to stay informed.
