I Bet My Own Money on Polymarket Weather — You Get the Same Picks Free
Polyforecast sends free daily Polymarket weather trading signals. James Cole, a former climate data analyst from Denver, CO, runs five independent forecast models (GFS, ECMWF, ECMWF-AI, ICON, GEM) against every weather market on Polymarket. When the models disagree with the market price, he takes the trade with his own money and emails subscribers the same pick that morning.
