IBKR settles Denver temperature on KBKF

KBKF is Buckley Space Force Base, Denver. IBKR ForecastEx settles 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

IBKR ForecastEx uses KBKF (Buckley Space Force Base). Kalshi and Polymarket settle the same city on KDEN (Denver International) 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.
