Contact Congress about S. 4160: Prediction Markets Are Gambling Act

People could not trade sports or casino-style event contracts on federally regulated commodity markets. State gambling laws would still apply. Older contracts would not be changed by this new ban.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

Prediction Markets Are Gambling Act is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on Agriculture, Nutrition, and Forestry.

Latest action on S. 4160: Read twice and referred to the Committee on Agriculture, Nutrition, and Forestry.

Who this affects: This bill mainly affects federally registered trading platforms and clearinghouses that might offer sports or casino-style event contracts. It also affects traders who want to buy or sell those contracts on regulated commodity markets. State gambling regulators and gambling businesses would still operate under state law, because the bill does not replace state rules.

Why this matters: This bill matters because it would keep sports and casino-style betting out of federally regulated trading markets. Today, some event contracts can look like bets even when they are built as financial products. The bill would draw a clear line for sports and casino-style games. It would also leave states in charge of their own gambling rules, while leaving the treatment of other event contracts less clear.

Key provisions in S. 4160

  • Adds a new rule to the Commodity Exchange Act, the federal law for commodity trading markets. The rule clearly bans some event contracts.
  • Stops registered market entities from listing, trading, or clearing contracts tied to sports, athletic contests, or casino-style games.
  • Defines casino-style games to include slots, video poker, blackjack, roulette, craps, other casino table games, bingo, lotteries, and digital copies of those games.
  • Defines sports and athletic contests broadly. It covers live or virtual contests based on physical activity or skill, including amateur, college, and professional sports.
  • Makes this ban apply even if other rules in the same part of the Commodity Exchange Act might otherwise allow review or listing.
