Atlanta temperature market FAQ

Which weather station settles the Atlanta temperature markets?

Kalshi, Robinhood, Polymarket and IBKR markets use Hartsfield-Jackson Atlanta (KATL).

How do the Atlanta temperature markets settle?

Kalshi settles Atlanta high and low markets on the official high or low for KATL's NWS climate location, as reported by The Weather Company (then the National Weather Service). Polymarket settles on the hourly data ("Show Hourly Data") of NOAA's weather.gov timeseries for KATL, in whole °F: the highest reading of the day for daily highs and the lowest for daily lows. Weather Underground's Daily Observations table is used only if NOAA's data for the day is unavailable by 11:59 PM ET the next day. Robinhood and IBKR list ForecastEx Atlanta temperature contracts, which settle on the Weather Underground Daily Observations table for KATL: the highest reading of the local calendar day for highs and the lowest for lows. The day is final once Weather Underground publishes the first observation of the next day.

What are the Kalshi, Robinhood and Polymarket tickers for Atlanta temperature?

Kalshi lists the Atlanta daily high under series KXHIGHTATL and the daily low under KXLOWTATL. Each day is its own event, such as KXHIGHTATL-26OCT16 for October 16, 2026, with one market per strike. On Robinhood and IBKR, the ForecastEx Atlanta daily high is UHATL and the daily low ULATL. Each contract is one strike on one day: UHATL_101626_80 asks whether the high exceeds 80 °F on October 16, 2026, and ULATL contracts ask whether the low is below a strike. Polymarket has no tickers. Its daily event is titled "Highest temperature in Atlanta on October 16?" with the slug highest-temperature-in-atlanta-on-october-16-2026, and the daily low event's slug starts with lowest-temperature-in-atlanta.

What are UHATL and ULATL?

They are the ForecastEx daily high and low temperature products for Atlanta, listed on Robinhood and IBKR. ForecastEx, not Kalshi, is the exchange. UHATL contracts ask whether the day's highest temperature at Hartsfield-Jackson Atlanta (KATL) will exceed a strike, and ULATL contracts whether the lowest will be below one, with strikes 1 °F apart. Both settle on Weather Underground's Daily Observations table for KATL for the local calendar day. Kalshi's Atlanta markets read the same station but settle on the official high or low for its NWS climate location as reported by The Weather Company, not on Weather Underground.

Can I trade Atlanta temperature markets on Coinbase?

Yes. Coinbase lists Kalshi's Atlanta temperature markets (KXHIGHTATL, KXLOWTATL) under the same tickers: the markets are operated by Kalshi, share Kalshi's order book and settle by Kalshi's rules, on the same station. Coinbase's prediction markets are not available to Nevada or Michigan residents.
