Prediction markets post record $188B Q3 volume as appeals court lets states restrict sports contracts
- Prediction markets post record $188B Q3 volume as appeals court lets states restrict sports contracts — Combined prediction-market volume hit a record $188B in Q3 2026, up nearly 70% quarter-over-quarter and 21x year-over-year, with Kalshi's sports trading driving the surge and permanently pulling ahead of Polymarket. A federal appeals court sided with Ohio and Tennessee on September 25, classifying the sports contracts as gambling and allowing states to restrict where Kalshi sells them. (Zubiqo)
