Contract sources
Only rules already checked for this desk. No extra cities, no prices, and no scores.
Kalshi
Kalshi's live rules name a third-party weather provider first, then official sources. Kalshi's help article still says something else: the official daily climate report for daily markets, and a third-party weather provider for the separate hourly market.
polymarket.com
Temperature markets on polymarket.com use the official time series. a third-party weather site is used only if official has no data by 11:59 PM ET the next day.
Polymarket US
Polymarket US uses the official daily climate report for New York Central Park, San Francisco, Miami, Chicago Midway, and Los Angeles.
Robinhood and IBKR
Robinhood and IBKR listings follow ForecastEx. January 2026 ForecastEx terms say a third-party weather site. IBKR has no current city list.
