Polymarket’s U.S. app turns Bitcoin bets into 15-minute rounds
Polymarket’s U.S. app now lets users trade Bitcoin’s direction every 15 minutes. Each market asks whether BTC finishes the interval higher or lower, turning prediction-market activity into a stream of rapid, recurring price calls instead of longer-horizon bets. The 15-minute crypto markets went live on September 28, 2026.
