US Senators Move to Ban Sports Betting on Prediction Markets

New bipartisan bill targets platforms like Polymarket and Kalshi, threatening $64 billion in annual sports trades.

The Brief

  • The 'Prediction Markets Are Gambling Act' was introduced on March 23, 2026, aiming to prohibit sports-related contracts on prediction markets.
  • Weekly trading volumes on these platforms have surged to over $5.9 billion, predominantly in sports betting.
  • If passed, the bill could collapse sports contract values and increase legal uncertainty for existing positions.
  • Nearly $64 billion was traded on these markets last year, mostly in sports-related contracts.
  • Traders may pivot to non-sports events or traditional sportsbooks if the bill becomes law.

The Story

The US Senate has taken a bold step towards reshaping the landscape of prediction markets with the introduction of the 'Prediction Markets Are Gambling Act'. This bipartisan bill, introduced on March 23, 2026, specifically targets platforms like Polymarket and Kalshi, aiming to prohibit sports-related contracts. The move comes amid a surge in trading volumes, which have exceeded $5.9 billion weekly, with the majority of these trades centered around sports betting.

This regulatory push could have profound implications for the prediction market industry. With nearly $64 billion traded last year, predominantly in sports-related contracts, the passage of this bill risks collapsing the value of these contracts and introducing significant legal uncertainty for existing positions. The bill's introduction has already sent shockwaves through the community, prompting discussions about the future of sports betting on these platforms.

Beyond the immediate impact on trading volumes and contract values, this legislative move could lead to a broader reevaluation of how prediction markets operate. Traders may be forced to pivot towards non-sports events or traditional sportsbooks, potentially altering the dynamics of these markets. Additionally, the bill could spark a debate about the regulation of prediction markets more broadly, raising questions about the balance between innovation and oversight in the financial technology sector.

Market Impact

The introduction of this bill directly impacts championship futures, player performance props, and bracket prediction markets, causing immediate repricing and increased volatility. Traders should closely monitor the bill's progress through Congress, as its passage or failure will be the key catalyst resolving the current uncertainty.
