Lowest temperature in Houston on May 28, 2026?

The market resolves on May 29, 2026. Resolution is determined by the official recorded lowest temperature in Houston on May 28, 2026. The specific temperature threshold or range that triggers each outcome is established at market creation and remains fixed throughout the trading period. Once the date passes and the actual minimum temperature is recorded by the designated weather authority, the outcome is determined and all shares are settled accordingly. Traders who correctly predicted the temperature range receive their winnings.

Several factors could shift odds before resolution. Extended-range weather forecasts updated in spring 2026 will provide more precise temperature predictions for late May. Seasonal climate patterns, including El Niño or La Niña conditions, influence Texas weather. Unusual atmospheric circulation patterns or tropical systems developing in the Gulf could alter expected temperatures. Historical May temperature records and anomalies in spring warming trends may prompt traders to adjust positions. As May 28 approaches, standard 10-day forecasts will become increasingly accurate, likely driving significant price movement in the final trading days.
