A newly revised version of the CLARITY Act, released just days before a key Senate vote, has sparked significant concern among tribal gaming nations who view the changes as a threat to their sovereignty and regulatory control.
The 630-page bill update, unveiled by Senate Banking Digital Assets Subcommittee Chair Cynthia Lummis, includes provisions affecting prediction markets and decentralized finance (DeFi) that tribal operators say could undermine their authority. The bill is set for a procedural Senate vote soon; failure to pass would effectively end the legislation ahead of the midterm elections.
Tribal gaming representatives, led by Indian Gaming Association chairman David Bean, have voiced strong opposition. Bean criticized the bill for expanding the Commodity Futures Trading Commission’s (CFTC) regulatory reach, calling it the largest since the 2010 Dodd-Frank Act. He highlighted that the bill “does nothing to rein in the (Commodity Futures Trading Commission),” and instead broadens its power in ways that could conflict with tribal and state gaming laws.
One key concern is the bill’s treatment of prediction markets, which are platforms allowing bets on event outcomes. The revised text narrows DeFi provisions to spot and case digital commodity transactions, a change intended to reduce regulatory risks for prediction markets. However, tribal leaders argue this does not sufficiently protect their sovereignty or clarify that federal commodities law should not override tribal gaming regulations.
Bean emphasized that until the bill explicitly states that tribal and state gaming laws, including the Indian Gaming Regulatory Act, remain unaffected by federal commodities law—and that designated contract markets (DCMs) cannot list contracts on sports betting or casino games—tribal nations will oppose the legislation. He described the CLARITY Act as “the greatest threat to tribal sovereignty in a generation.”
For players and bettors, this legislative uncertainty could impact the availability and regulation of prediction markets, especially those linked to tribal gaming operations. It also raises questions about how federal oversight might change the legal landscape for tribal casinos and online platforms.
Senator Mike Rounds of South Dakota, a state with significant tribal gaming interests, expressed skepticism about the bill’s prospects, telling media, “Does not look good right now,“ regarding the Senate’s chances of passing the measure.
Players interested in prediction markets or tribal gaming should monitor this legislation closely, as its outcome may affect market access, regulatory protections, and the balance of authority between federal agencies and tribal governments.
