Crypto Prediction Markets Face Sports Bet Ban

U.S. lawmakers are pushing to ban sports-event wagering on crypto prediction markets, targeting the very bet category that drove platforms like Polymarket to mainstream adoption.

Sports Bets Turned Prediction Markets Into a Crypto Phenomenon

Sports and political event contracts became the breakout use case for on-chain prediction platforms after 2024. Polymarket, the largest decentralized prediction market, saw record trading volumes as retail users flocked to wager on high-profile sporting events and election outcomes.

The surge in sports-related contracts brought a wave of new participants who had never interacted with crypto derivatives before. That retail momentum helped prediction markets become one of the fastest-growing sectors in decentralized finance, a trend that also coincided with shifting retail sentiment across broader crypto markets.

Lawmakers Move to Restrict the Wagers That Fueled Growth

Senator Jeff Merkley has introduced legislation that would ban sports betting on prediction market platforms, framing the contracts as unregulated gambling rather than legitimate financial instruments.

The bill, referred to as the PREDICT Act, would specifically prohibit officials from placing political bets and restrict sports-event contracts on platforms operating in or accessible from the United States. The legislation targets the contract categories that account for the bulk of retail trading activity on these platforms.

Multiple U.S. senators have backed the push to classify sports betting on prediction markets as a regulatory concern, arguing that the contracts blur the line between derivatives trading and gambling.

The regulatory pressure comes as prediction markets were gaining legitimacy following their accurate performance during recent election cycles. The timing creates an unusual dynamic where the sector’s most popular product faces restriction just as the broader market matures, not unlike the uncertainty that has kept Bitcoin traders cautious heading into the weekend.

What a Ban Means for Prediction Market Platforms Going Forward

If enacted, the legislation would strip prediction platforms of their highest-volume contract category. Sports-event markets have consistently ranked among the top traded categories, and removing them could significantly reduce platform activity and total value locked.

The proposal also raises migration risk. Users seeking sports-event contracts could move to offshore or fully decentralized alternatives beyond U.S. jurisdictional reach, fragmenting liquidity rather than eliminating demand. This mirrors patterns seen across crypto when DeFi protocols adapt to regulatory shifts by building new protective mechanisms.

Whether the PREDICT Act advances through committee or stalls will depend on bipartisan appetite for regulating a sector that straddles finance and entertainment. The bill’s progress through the Senate remains the key watchpoint for prediction market participants in the weeks ahead.
