Indian Gaming Association Urges Congressional Action Following Senate Roundtable on Prediction Markets

Key Takeaways

• Regulatory scale: IGA told the committee tribal governments invest more than $450 million a year in gaming regulation and employ more than 6,000 regulators.
• The question is jurisdictional: whether sports and casino-style wagering can be offered outside IGRA and the tribal-state compacts.
• The asks: advance the Prediction Markets Are Gambling Act (S. 4160), preserve IGRA authority in the CLARITY Act, and restrain the CFTC.
• The gap: national impact data is still being compiled, and depends on operators sharing proprietary figures voluntarily.

The Indian Gaming Association has urged Congressional action after Vice Chairman Tehassi Hill participated in a U.S. Senate Committee on Indian Affairs roundtable examining prediction markets’ growth and tribal implications. Hosted by Committee Chairman Sen. Lisa Murkowski and Vice Chairman Sen. Brian Schatz, the session featured a panel that delivered a unified position on protecting tribal sovereignty, governmental revenues, and long-established regulatory systems.

The association’s framing is jurisdictional rather than oppositional. Prediction markets offering sports and casino-style wagering sit outside the frameworks built under the Indian Gaming Regulatory Act and the tribal-state compacts, which IGA characterises as a federal workaround around four decades of collaborative work. Indian Country, it stressed, supports responsible innovation and legitimate financial markets.

Roundtable Panel Delivers Unified Message on Sovereignty

Vice Chairman Tehassi Hill, Chairman of the Oneida Nation, joined Mark Macarro, President of the National Congress of American Indians; Jamie Hummingbird, Chairman of the National Tribal Gaming Commissioners & Regulators; Mathura Sridharan, Solicitor General for the State of Ohio; and Dr. Harry Levant, Director of Gambling Policy for the Public Health Advocacy Institute.

The panel told senators that these markets threaten tribal revenues, consumer protections, and sovereignty. Hill emphasized the foundational role of tribal gaming. “Tribal gaming is not simply an industry. It is the economic foundation that enables Tribal governments to provide healthcare, education, housing, public safety, infrastructure, and other essential services for our citizens.”

Macarro noted that Congress never intended the Commodity Exchange Act to supersede the Indian Gaming Regulatory Act. Hummingbird detailed the licensing, auditing, responsible gaming measures, and compact enforcement that tribal commissions have built. Sridharan reminded participants that gambling regulation has historically rested with states due to their duties regarding public health, safety, and consumers. Levant shared his experience with gambling addiction and warned of increased access for young adults and vulnerable populations without regulated protections.

The Scale of Tribal Investment in Regulation

According to figures the Indian Gaming Association presented to the committee, tribal governments have spent more than four decades working with Congress, states, and federal regulators to construct one of the nation’s most comprehensive gaming oversight systems. On the association’s account they invest more than $450 million annually in gaming regulation and employ more than 6,000 gaming regulators focused on integrity, responsible practices, and consumer safeguards.

This apparatus did not emerge overnight. It reflects sustained collaboration and direct tribal funding. The roundtable highlighted how prediction markets risk eroding the economic base that supports these systems and the essential services they fund. When unregulated channels divert activity, the arithmetic of tribal-state compacts shifts without renegotiation or consultation.

If those figures hold, they describe something more than compliance spending. In my own experience advising tribal nations and operators over more than thirty years, an apparatus of that size is a structural commitment, and it produces consumer and integrity standards that a purely financial-markets overlay does not replicate. That is the substance of the panel’s argument, and I think it is the right one: a channel that sits outside the perimeter is not innovation so much as a transfer of risk onto governments that did the building.

Specific Legislative Measures IGA Has Prioritized

Hill called for immediate Congressional steps. These include advancing the Prediction Markets Are Gambling Act (S. 4160), ensuring the CLARITY Act fully preserves Indian Gaming Regulatory Act authority and tribal-state gaming compacts, and blocking the Commodity Futures Trading Commission from expanding sports and casino-style gambling via prediction markets.

The Indian Gaming Association framed these asks as necessary to maintain clear boundaries. Chairman David Z. Bean commended Hill and the panel for presenting a unified voice. “Today’s discussion demonstrated that Tribal leaders, Tribal regulators, state governments, and public health experts are united in recognizing the risks posed by prediction markets operating outside established gaming law.”

The Evidence Gap and Its Commercial Implications

During questioning on economic impacts to tribal gaming, Hill acknowledged that the Indian Gaming Association is working with tribes to compile national data. He noted that proprietary gaming data must be voluntarily shared by tribal operators. Collaborative research efforts among Wisconsin tribes illustrate the industry’s commitment to building reliable information.

This concession is material. The absence of comprehensive, aggregated impact figures represents the most candid limitation in the current tribal position. It is also the most addressable. Voluntary data sharing can be expanded through industry associations and trusted intermediaries without compromising competitive sensitivities.

For operators and suppliers, the roundtable signals that perimeter risk has moved from theoretical to immediate. Diligence reviews for new products, partnerships, or market entries should now treat potential jurisdictional overlap as a live variable. Client-partners in tribal gaming cannot assume the existing compact equilibrium will remain undisturbed if parallel channels expand without legislative clarification.

The Jurisdictional Inflection Point for Compacts

The roundtable and subsequent Indian Gaming Association statement clarify what is truly at stake. This is not a blanket resistance to financial innovation. It is a defense of the specific regulatory perimeter that Congress established through the Indian Gaming Regulatory Act and that tribes negotiated in compacts with states.

A federal commodities pathway for sports and casino-style wagering would alter revenue expectations baked into those instruments — expectations that underwrite bonds, infrastructure and essential services. Once that arithmetic moves unilaterally, renegotiation gets harder and the sovereignty question sharpens.

Operators, investors and regulators should treat this as an active inflection point rather than a hearing to monitor. A unified tribal, state and public-health position makes legislative movement more likely, and whether it arrives through S. 4160 or through refinements to the CLARITY Act, the outcome will set where the line falls between a legitimate prediction market and regulated gaming. Everyone on both sides of that line benefits from Congress drawing it precisely.
