The market resolves on Jun 2, 2026, after the highest temperature in Washington DC on June 1, 2026 has been recorded and verified. Resolution is determined by the actual observed maximum temperature on that date, sourced from official weather data. Once the temperature is confirmed, the corresponding outcome contract settles to its final value, and all other contracts expire worthless. Traders who correctly predicted the temperature range or exact value receive their payout based on the contract price they paid.

Several factors can shift market odds before resolution. Long-range weather models and seasonal forecasts updated by meteorological agencies will influence trader expectations. Climate patterns such as the position of the jet stream, presence of high-pressure systems, or tropical activity can signal warmer or cooler conditions. Historical temperature data for early June in DC provides a baseline. As spring 2026 progresses, real-time weather developments—including unusual heat waves or cool spells—will be priced in. Major climate anomalies or shifts in seasonal patterns closer to June 1 could trigger significant repricing of temperature outcomes.
