Phoenix temperature market FAQ

Which weather station settles the Phoenix temperature markets?

Kalshi, Robinhood and IBKR markets use Phoenix Sky Harbor International (KPHX).

How do the Phoenix temperature markets settle?

Kalshi settles Phoenix high and low markets on the official high or low for KPHX's NWS climate location, as reported by The Weather Company (then the National Weather Service). Robinhood and IBKR list ForecastEx Phoenix temperature contracts, which settle on the Weather Underground Daily Observations table for KPHX: 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 and Robinhood tickers for Phoenix temperature?

Kalshi lists the Phoenix daily high under series KXHIGHTPHX and the daily low under KXLOWTPHX. Each day is its own event, such as KXHIGHTPHX-26OCT16 for October 16, 2026, with one market per strike. On Robinhood and IBKR, the ForecastEx Phoenix daily high is UHPHX and the daily low ULPHX. Each contract is one strike on one day: UHPHX_101626_80 asks whether the high exceeds 80 °F on October 16, 2026, and ULPHX contracts ask whether the low is below a strike.

What are UHPHX and ULPHX?

They are the ForecastEx daily high and low temperature products for Phoenix, listed on Robinhood and IBKR. ForecastEx, not Kalshi, is the exchange. UHPHX contracts ask whether the day's highest temperature at Phoenix Sky Harbor International (KPHX) will exceed a strike, and ULPHX contracts whether the lowest will be below one, with strikes 1 °F apart. Both settle on Weather Underground's Daily Observations table for KPHX for the local calendar day. Kalshi's Phoenix 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 Phoenix temperature markets on Coinbase?

Yes. Coinbase lists Kalshi's Phoenix temperature markets (KXHIGHTPHX, KXLOWTPHX) 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.
