Kalshi hits $6B NFL weekend record on longshot parlay flow
Kalshi set fresh records for trading volume and fee revenue on September 19 and 20, driven by longshot parlay bets on NFL matchups. The weekend generated approximately $6 billion in volume. Most parlay bettors finished with losses. The milestone lands amid expanding competition from Crypto.com, Novig, Underdog, and Robinhood. Fee revenue also reached a new high. Most parlay takers finished the weekend with significant losses.
The $6 billion figure reopens the question Kalshi first faced with its $4.9 billion Week 1 record: whether FanDuel's market-making balance sheet can sustain this pace without choking pricing or pulling capital. Most parlay bettors lost money, which feeds the CFTC's running concern that sportsbook-style presentation is luring gambling-native users into structured losses on a regulated exchange. Kalshi now has two consecutive record weekends proving it can match sportsbook scale.
That scale draws regulatory scrutiny precisely because it works. The platform must keep FanDuel committed through the playoff cycle while fending off Polymarket and Novig. Any slip in order-book depth or any product change forced by the CFTC's American-odds crackdown would accelerate trader migration. The platform that holds liquidity and regulatory standing through January owns the political cycle.
