Gaming groups lobby Senate to ban sports betting on Polymarket and Kalshi via the CLARITY Act. Odds of passage drop to 44% with lawmakers focused on ethics and DeFi.
National, tribal, and state gaming groups are lobbying senators to include language in the CLARITY Act that would ban sports betting on prediction markets like Polymarket and Kalshi. The push comes as the Senate faces a deadline to advance the crypto bill before the July 4 recess. The groups are expected to intensify their efforts this week.
Banking groups have also renewed efforts to include a broad ban on stablecoin yield in the same bill. The Senate's focus has shifted instead to ethics and decentralized finance issues, according to CoinGape. Member meetings and staff-level negotiations are expected to continue throughout this week.
Sources told Crypto in America that negotiations to include the sports betting language are unlikely to gain traction. Lawmakers are focused on resolving outstanding issues like illicit finance and merging the crypto bill with the Agriculture Committee text. The Digital Chamber is meeting with senators and staff to advocate for the bill's passage. It also plans to meet with House members to discuss crypto tax legislation, including the tax discussion drafts released by the House Ways and Means Committee.
Polymarket data shows a 44% chance of President Donald Trump signing the CLARITY Act into law this year. The 44% is down from a recent high of around 74% when the Senate Banking Committee advanced the bill in May.
A ban on sports betting would remove a key use case for Polymarket and Kalshi. Both platforms have built volume around sports contracts. Polymarket's own odds market would lose a significant category. For other prediction market platforms, the read-through is similar: any legislative restriction on event contracts could limit their addressable market. The outcome of the CLARITY Act negotiations will set a precedent for how Congress treats prediction markets.
The Senate has scheduled last-minute meetings to resolve outstanding issues. Sen. Bill Hagerty has signaled that the CLARITY Act could still pass by July 4.
