Polymarket Temperature Markets

• Daily high. One event per city per day, titled like “Highest temperature in Miami on October 16?”, with the slug highest-temperature-in-miami-on-october-16-2026. Each temperature range is a market inside the event.
• Daily low. The same with “Lowest temperature” and a lowest-temperature-in- slug. Polymarket has listed daily lows in every city here except Auckland, Jakarta and Lagos.

Polymarket temperature markets do not use the NWS climate report (CLI) that Kalshi uses. Their rules name NOAA's weather.gov timeseries for the market's station as the resolution source: a daily high resolves on the highest reading in its “Temp” column for the day, and a daily low on the lowest. US markets use the hourly data (“Show Hourly Data”); other cities use the station's “Temp” readings. 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. Taipei is the exception: it settles on Weather Underground's Daily Observations table. Some cities use a different station than Kalshi, such as LaGuardia (KLGA) for New York and O'Hare (KORD) for Chicago.

The rules can vary by market, so check each market's resolution criteria on Polymarket for the exact source. More detail: how temperature markets settle.

The event slugs and the station each Polymarket city settles on. Replace <date> with the day, like october-16-2026.

What are Polymarket temperature event slugs?

Polymarket has no tickers. Each city has one event per day, titled like "Highest temperature in Miami on October 16?", and the event URL uses a slug built from the title: highest-temperature-in-miami-on-october-16-2026. Daily low events use lowest-temperature-in-<city>-on-<date>. Each outcome, such as a temperature range, is a market inside that event.

How do Polymarket temperature markets settle?

Not on the NWS climate report (CLI) that Kalshi uses. Their rules name NOAA's weather.gov timeseries for the market's station (weather.gov/wrh/timeseries?site=<station>) as the resolution source: a daily high resolves on the highest reading in its "Temp" column for the day, and a daily low on the lowest. US markets use the hourly data ("Show Hourly Data"); other cities use the station's "Temp" readings. 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. Taipei is the exception: it settles on Weather Underground's Daily Observations table for RCSS. The rules can vary by market, so check each market's resolution criteria on Polymarket for the exact source.

Does Polymarket use the same station as Kalshi?

Not always. In New York, Polymarket uses LaGuardia Airport (KLGA) while Kalshi uses Central Park (KNYC), so the same day can settle on two different highs. The table above shows the station for every city.

Is Polymarket US the same as Polymarket?

No. Polymarket US is a separate, CFTC-regulated US exchange with its own markets. Its daily high temperature markets settle on the NWS CLI for the same stations Kalshi uses.
