NFL Backs States Against Kalshi at Supreme Court
The league urges SCOTUS to resolve whether sports prediction contracts are gambling or federal swaps.
The NFL filed a brief urging the Supreme Court to take up the Kalshi prediction market case, arguing that sports event contracts on prediction platforms constitute gambling subject to state regulation — not federally protected financial swaps.
Why It Matters
The Supreme Court's eventual ruling will determine whether prediction markets like Kalshi can offer sports contracts nationwide under federal commodities law, or whether individual states retain the authority to ban them as unlicensed gambling. As of October 2026, a circuit split exists between federal appeals courts, creating a patchwork of legal standards that leaves operators, bettors, and regulators in limbo. For anyone trading sports outcomes on prediction platforms, the stakes are direct: a ruling favouring state authority could effectively shut down sports-linked prediction contracts in states with strict gambling laws. Gambling always carries financial risk, and regulatory uncertainty amplifies that risk further.
Context
Kalshi, a CFTC-regulated prediction market, has argued its sports event contracts are legally distinct from gambling because they are classified as swaps under the Commodity Exchange Act, placing them outside state gambling jurisdiction. Several states — backed now by the NFL — counter that the functional reality of wagering on game outcomes makes these products gambling regardless of federal classification, per Decrypt's reporting. The circuit split the NFL references means different federal courts have reached contradictory conclusions, a condition that historically prompts the Supreme Court to intervene.
What's Next
The Supreme Court must first decide whether to grant certiorari — accepting the case for full review — which could happen as early as the court's current term. A decision to hear the case would set the stage for a landmark ruling on the boundary between federal commodities regulation and state gambling law.
