Kalshi Posts Back-to-Back $5.3B Days, Topping Its October Record

Kalshi recorded back-to-back daily notional volume records of $5.33 billion on Nov. 7 and $5.36 billion on Nov. 8, surpassing its prior single-day high of $5.30 billion set on Oct. 24. Parlay-style combo contracts accounted for roughly three-quarters of volume on both record days. The surge came one day after the American Gaming Association submitted comments to federal regulators, underscoring growing scrutiny of event-contract markets as they scale. The consecutive records signal that demand for multi-leg prediction-market products is accelerating rather than fading after October's peak. Watch whether combo-driven volume holds through the coming week and how regulators respond to the AGA's push.
