Tribal gaming leaders are fighting to keep prediction markets under state and tribal control instead of handing them over to federal regulators. During a Senate Indian Affairs Committee hearing Tuesday, Indian Gaming Association Vice Chairman Tehassi Hill made the case that sports and casino gambling prediction markets should remain subject to existing state and tribal gaming laws, not fall under the exclusive authority of the Commodity Futures Trading Commission.
Hill argued Congress needs to amend the Clarity Act to explicitly block prediction markets from bypassing traditional gaming rules. The proposal would make clear that state gaming laws and the Indian Gaming Regulatory Act, rather than federal commodities law, should govern those markets. Tribal gaming groups worry that expanding federal CFTC oversight could weaken the local authority over sports wagering that states and tribes have controlled for decades.
The debate matters because prediction markets are exploding. Trading volume hit a record $50.59 billion in July alone, even as regulators fight over who gets to oversee them. The CFTC keeps asserting its authority while several states challenge that position in court. Sen. Tina Smith, D-Minnesota, suggested lawmakers could insert clarifying language into either the Clarity Act or the Farm Bill, which Congress frequently uses for policy provisions beyond agriculture.
Senate leadership is pushing to resolve this before lawmakers head home for August recess, with the November elections looming and legislative time shrinking fast. The Clarity Act, which Congress is weighing as part of broader crypto market structure legislation, could become the vehicle for settling the question of which regulator gets final say over this rapidly growing segment of the financial markets.
