Kalshi and Polymarket US settle New York temperature on KNYC

KNYC is Central Park, New York. Kalshi and Polymarket US settle temperature contracts here. Below: the resolution source each venue names, when the station reports, and how long a reading takes to reach the public feed.

This city settles on two different stations

Kalshi and Polymarket US use KNYC (Central Park). Polymarket and IBKR ForecastEx settle the same city on KLGA (LaGuardia Airport) instead. The two sites can report different temperatures at the same moment and land in different contract buckets on the same day, so a reading from one tells you nothing definitive about the other.
