NFL asks Supreme Court to let states regulate sports prediction markets

The NFL has urged the U.S. Supreme Court to allow state gambling regulators to oversee sports prediction contracts offered by platforms such as Kalshi and Polymarket.
In a 24-page brief filed Thursday, the league argued that contracts tied to game outcomes are bets rather than financial instruments used by businesses to hedge risk. The NFL said states have traditionally regulated gambling and asked the court to provide clarity “before another NFL season goes by,” citing concerns about preserving game integrity.
According to Fortune, nearly $2 billion was traded on NFL games through prediction-market platforms on the opening Sunday of the 2026 season, representing more than half of prediction-market volume that day. The league’s position differs from that of Major League Baseball, Major League Soccer and the National Hockey League, which have formed partnerships with Kalshi or Polymarket.
The dispute centers on whether federal oversight by the Commodity Futures Trading Commission preempts state gambling laws. In August, the Ninth U.S. Circuit Court of Appeals allowed Nevada regulators to enforce state requirements against Kalshi’s sports contracts. That ruling conflicted with an April decision by the Third Circuit, which classified Kalshi’s contracts as federally regulated swaps in a case involving New Jersey.
The Supreme Court has not agreed to hear the case. Polymarket said it supports a harmonized federal framework and is working with federal regulators and professional leagues. Kalshi did not immediately comment to Fortune.
