Prediction Markets Surge to $68B Monthly Volume Amid Sportsbook Stock Decline

Prediction Market Volume Doubles With Football Season

Trading activity in sports prediction markets nearly doubled with the return of football, reaching a combined $68 billion in notional volume across tracked exchanges during the month, according to data from Aldrin Research. This surge contrasts sharply with the performance of publicly traded sportsbook companies.

Shares of Draftkings and Penn Entertainment, the two largest U.S. sportsbook operators, have both fallen to multi-year lows. The divergence suggests a potential shift in where investors and traders are directing capital within the broader iGaming sector.

Kalshi continues to hold the largest share of the prediction market, but competitors are experiencing faster growth rates. Aldrin Research data shows a significant increase in activity across various exchanges, indicating growing interest in these alternative betting platforms. The data tracked includes both sports and combined contract types.

The increased volume in prediction markets may reflect a desire for more transparent and potentially more profitable trading opportunities compared to traditional sportsbooks. It also highlights the growing sophistication of traders seeking to capitalize on event outcomes beyond simple win/loss bets.
