Kalshi weather bots
Kalshi weather bots are programs that trade Kalshi's climate and weather markets, mostly the daily highest-temperature series such as KXHIGHNY (Central Park, New York), by comparing weather forecasts with market prices. Our directory lists one Kalshi weather bot, plus one for Polymarket weather markets; four more public Kalshi weather repos are linked below.
The short answer: the most-starred open-source option is the weather temperature market bot, which trades KXHIGH markets on Kalshi and weather markets on Polymarket. The other repos are smaller projects, several of them university course work using Kalshi's demo environment. Kalshi's own market-data quick start uses KXHIGHNY as its example (Kalshi: Quick Start, Market Data ↗).
In the Becker Kalshi dataset, Kalshi's climate and weather category has 48,981 markets with 284,181,004 contracts of volume; KXHIGHNY alone has 2,382 markets and 52,070,182 contracts (whole-dataset counts through Nov 2025; more weather data).
