Senate Proposes Ban on Sports Betting for Prediction Market Platforms like Kalshi and Polymarket

A bipartisan bill introduced by Senators Adam Schiff and John Curtis seeks to bar CFTC-regulated prediction market platforms from offering contracts tied to sports events, a move that could reshape the US gambling landscape. The proposed legislation targets platforms like Kalshi and Polymarket, which currently operate under federal derivatives regulations, bypassing state-level gambling laws. These platforms have grown to a combined valuation of nearly $20 billion, with sports betting making up approximately 90% of Kalshi's trading volume.

The bill reflects growing concern over consumer protections and the impact of prediction markets on traditional gambling operators. It has been supported by lawmakers who argue that these platforms exploit a regulatory gap by avoiding state licensing and consumer protection requirements. The legislation has also drawn attention to potential risks of addiction, particularly among younger demographics in states like Utah.

Traditional sports betting operators have already seen market reactions to the proposed legislation. Shares of companies like Flutter and DraftKings have risen in response to the potential shift in regulatory dynamics. This development is seen as a step toward protecting state-level gambling interests and consumer rights, with multiple states already taking legal action against prediction market platforms.

Why Did This Happen?

The bill is part of a broader regulatory and legal battle over how prediction markets should be classified and regulated. Federal regulators, specifically the CFTC, have asserted jurisdiction over these markets by classifying event contracts as a financial asset class. However, states like Nevada and Arizona argue that these markets should be treated as gambling operations and subject to state-level control.

Senator John Curtis has highlighted concerns that Utah residents are being exposed to addictive betting contracts not governed by state laws. His involvement signals a broader bipartisan concern over the societal and economic implications of prediction markets.

How Did Markets React?

The proposed legislation has already influenced market dynamics. Shares of traditional gambling operators like Entain and Flutter have seen significant gains following the announcement. This surge suggests market participants view the bill as a potential opportunity for traditional platforms to regain competitive ground.

Kalshi, which reports that sports betting constitutes a large share of its activity, faces heightened legal pressure. Arizona has filed criminal charges against the company, and Nevada has issued court orders against it. These state-level actions are intensifying the regulatory scrutiny already facing the prediction market sector .

What Are Analysts Watching Next?

The proposed legislation could significantly alter the regulatory environment for prediction markets. Analysts are watching whether the bill will pass and how it might affect the operations of platforms like Kalshi and Polymarket. If enacted, the bill would restrict these platforms from listing contracts related to sports and casino-style games .

Another key area of focus is how the CFTC will respond to the bill. The agency has already classified event contracts as a financial asset class and is seeking public feedback on how to regulate them under the Commodity Exchange Act . The outcome of this feedback process could further influence the shape of any future regulatory framework.

The bill also raises broader questions about the balance between innovation and regulation. Prediction markets offer potential benefits such as improved forecasting and risk management, but their legal uncertainty poses a significant threat to their scalability and mainstream adoption . Analysts will continue to monitor how regulators and lawmakers address these challenges in the coming months.
