Tribal gaming representatives urged Congress to amend the Digital Asset Market Clarity Act during a Senate Committee on Indian Affairs roundtable, arguing that prediction-market platforms should not be allowed to offer sports or casino-style event contracts without following existing gambling laws.
The Aug. 4 roundtable focused on the rapid growth of prediction markets and their possible effect on tribal sovereignty, gaming revenue and consumer protection. Tribal witnesses asked lawmakers to make clear that the Commodity Futures Trading Commission does not have authority to override the Indian Gaming Regulatory Act, tribal-state compacts or state gaming regulations.
The discussion adds pressure to an already complicated debate over the CLARITY Act, a major cryptocurrency and digital asset market-structure bill. Tribal gaming groups say the legislation could create a pathway for prediction markets to expand nationwide while avoiding the licensing, taxation and responsible-gaming rules that apply to sportsbooks and casinos.
It was also a topic of discussion at this years's Indian Gaming Association Trade Show.
Tribal Leaders Challenge Prediction Market Model
Prediction-market operators generally describe their products as financial contracts rather than gambling. Under that view, contracts tied to sports results or other events fall under federal commodities law and the oversight of the CFTC.
Tribal representatives reject that position for sports-related products. They argue that a contract based on whether a team wins, covers a spread or reaches a certain result functions like a sports wager, regardless of whether the platform calls it a derivative or an event contract.
Sen. Brian Schatz, vice chairman of the Senate Committee on Indian Affairs, made a similar comparison during the roundtable. He said consumers may experience little difference between placing a wager through a traditional sportsbook and buying a contract on a prediction-market application.
The National Congress of American Indians and other witnesses said the use of financial terminology should not determine which laws apply. Their position is that the substance of the transaction matters more than the label attached to it.
Why IGRA Is Central to the Debate
The Indian Gaming Regulatory Act, commonly known as IGRA, established the main federal framework for gaming conducted by tribes. Class III activities, which include casino gaming and sports betting, generally operate under tribal-state compacts and related regulatory agreements.
Tribal gaming organizations say prediction markets could undermine that system if they offer similar products nationwide through federal commodities law. They argue that platforms operating outside the tribal-state framework would not face the same licensing requirements, age checks, tax obligations or responsible-gaming standards.
The dispute also involves tribal economic development. Gaming revenue supports a range of tribal government services, including healthcare, education, housing, infrastructure and public safety. Martin Heinrich and other senators warned in a July letter that the expansion of sports event contracts and casino-style products could weaken tribal gaming exclusivity and state regulatory authority.
Tribal leaders are also concerned that prediction-market activity could divert customers and revenue from regulated tribal casinos and sportsbooks.
What Tribal Groups Want Changed
The Indian Gaming Association and other gaming stakeholders are seeking specific language in the CLARITY Act. Their proposed approach includes two central protections:
A savings clause stating that the legislation does not preempt, repeal or limit IGRA, tribal-state compacts, state gaming laws or tribal gaming authority.
A restriction preventing CFTC-registered entities from listing contracts based on sports results, athletic performance or casino-style games.
The proposed language would also prevent decentralized finance platforms from using regulatory exemptions to offer sports betting or casino-style products outside established gaming laws.
Tehassi Hill, vice chairman of the Indian Gaming Association and chairman of the Oneida Nation, urged lawmakers to address the issue before prediction markets grow further. Tribal representatives also backed the Prediction Markets Are Gambling Act, or S. 4160, which would prohibit CFTC-regulated entities from listing sports and casino-style event contracts.
CLARITY Act Becomes Part of Larger Fight
The CLARITY Act is designed primarily to establish a federal framework for digital assets and cryptocurrency markets. It would address issues such as digital commodity classifications, exchange registration, broker and dealer requirements, custody rules, consumer protections and anti-money-laundering obligations.
However, tribal gaming groups say parts of the legislation could affect prediction markets, particularly if digital asset or decentralized finance provisions are interpreted broadly. They fear those provisions could provide additional legal cover for platforms offering contracts that resemble online gambling.
Senate Agriculture Committee Chair John Boozman cautioned that cryptocurrency policy and prediction markets are separate issues. Other lawmakers responded that the concern comes from language already included in the legislation, particularly provisions involving decentralized finance. Committee discussions reportedly included the possibility of revising that language.
The debate reflects a wider disagreement over federal and state authority. Prediction-market companies generally favor one national regulatory system under the CFTC. States and tribal gaming interests argue that sports betting and casino-style products should remain subject to local licensing and gaming rules.
What Happens Next?
The Senate amendment effort comes as lawmakers continue negotiating the CLARITY Act. Tribal gaming representatives want Congress to add protections before the legislation advances, while some lawmakers have questioned whether prediction-market provisions should be included in a broader digital asset bill.
The issue is also connected to ongoing litigation and regulatory activity involving sports event contracts. States, tribes and gaming regulators have argued that these products may violate existing gambling laws. Prediction-market operators have maintained that their contracts are financial products governed by federal commodities law.
No final resolution has been reached. The outcome may depend on Senate negotiations over the CLARITY Act, the separate Prediction Markets Are Gambling Act and possible changes to CFTC rules.
For tribal gaming leaders, the central question is straightforward: whether a sports wager should be regulated according to its financial label or the way consumers actually use it.
