The contracts are offered by Robinhood Derivatives through one of several named venues: KalshiEX LLC, ForecastEX LLC, Rothera Exchange and Clearing LLC, or North American Derivatives Exchange Inc.
Prediction markets are now tracking daily temperature highs and lows across major U.S. cities for mid-September 2026. Robinhood offers contracts through multiple exchanges where traders can bet on whether temperatures will exceed or fall below specific thresholds. Winning contracts pay $1 each, though fees and trading risks apply. Results are determined using real airport weather station data from Weather Underground.
How Airport Weather Stations Determine Winners
Each city contract ties to a specific airport station. Philadelphia uses Philadelphia International Airport (KPHL). Detroit uses Detroit Metropolitan Wayne County Airport (KDTW). Jacksonville uses Jacksonville International Airport (KJAX). Houston uses William P Hobby Airport (KHOU). Robinhood pulls daily temperature data directly from Weather Underground, not from other weather sources. This standardized approach ensures consistent settlement across all contracts.
Temperature Contracts Available Across 16 Cities
Traders can place bets on daily highs and lows in Philadelphia, Detroit, Jacksonville, Minneapolis-Saint Paul, Chicago, Atlanta, Oklahoma City, Dallas, Denver, Miami, Charlotte, Boston, Seattle, Nashville, Las Vegas, and San Antonio. Robinhood offers contracts for multiple date combinations through September. For example, Las Vegas has both high and low contracts for September 12 and 13. Boston covers lows on both dates. Each contract targets a single metric: either the day's high or low temperature.
Four Exchanges Handle Temperature Market Trading
Robinhood operates these contracts through four separate venues: KalshiEX LLC, ForecastEX LLC, Rothera Exchange and Clearing LLC, and North American Derivatives Exchange Inc. Each exchange uses the same Weather Underground airport data for settlement. Traders should verify they understand the fee structure and eligibility rules before placing bets. Weather prediction contracts carry real financial risk if temperatures move against your position.
Using Original Data Tables for Accurate Results
Robinhood warns users to rely on the original summary tables or direct Weather Underground observations rather than numbers displayed on the redesigned website. Prominent figures may not reflect the correct temperatures used for contract settlement. Always check the specific airport station code for your city. Confirming the source data before trading ensures you understand exactly which temperature measurements will determine if your contract wins or loses.
