  "account": "The NFL's prediction-market trading on the 2026 season's opening Sunday totaled $1.8 billion, representing 59% of combined notional volume across nine exchanges, according to USA TODAY's analysis. This figure, based on notional trading volume rather than actual cash spent, indicates that NFL-related contracts made up a significant portion of market activity. Kalshi and Polymarket together accounted for about 88% of trading across these exchanges during the 30 days leading up to Oct. 14. While the NFL's share of cash-paid betting was around half in Week 1, it grew to 60% by Oct. 11, and increased to 69% for notional volume. This surge in NFL-related trading occurred alongside a 62% increase in combined notional volume on Kalshi and Polymarket US between Sept. 13 and Oct. 11. The NFL has included this $1.8 billion figure in a Supreme Court brief supporting New Jersey regulators in a dispute over whether sports contracts on prediction markets should be subject to state gambling laws.",
