Prediction Market NFL Trading Volume Could Reach $57 Billion This Season
DeFi Rate projects Kalshi NFL trading volume will reach roughly $3.2 billion through Week 1 and $57 billion across the full 2026–27 season. The forecast reflects the sharp expansion in prediction-market participation and NFL contract inventory over the past year, while using last season’s week-by-week trading pattern to model how volume is likely to build across the season rather than extrapolating the current growth rate indefinitely.
