Tribal nations say sports-event contracts are unregulated sports betting that bypasses IGRA and four decades of tribal-state compacts. Here's what they're telling Congress — and why it matters.
Active Congressional Window — July 2026
The Indian Gaming Association held its 2026 Summer Legislative Summit on July 14-15 in Washington, D.C., where tribal leaders lobbied senators to amend the CLARITY Act before the August 10 Senate recess. This is the narrowest legislative window of the year.

The Indian Gaming Regulatory Act (IGRA, enacted 1988, 25 U.S.C. § 2701 et seq.) created the framework for tribal gaming. For Class III gaming — which includes sports wagering — tribes must negotiate compacts with their states and obtain federal approval. These compacts define revenue-sharing arrangements, regulatory authority, and the geographic and operational scope of gaming.
Tribes argue that CFTC-regulated prediction markets offering sports-event contracts effectively allow sports betting to reach customers nationally without triggering the compact process. Because prediction markets operate as federally regulated commodity exchanges, they are not subject to IGRA — and thus not subject to the tribal-state agreements that govern existing sports wagering.
IGA's CLARITY Act demand: Add amendments to H.R.3633 prohibiting sports and casino-style gambling through prediction markets, and affirm the legislation does not preempt IGRA.
Core Opponent
Prediction markets bypass IGRA and tribal-state compacts, threatening gaming revenues that fund tribal government services. IGA calls this 'one of the greatest threats in a generation.'
Active Litigants
Multiple states — Nevada, New York, Michigan — have sued or sought injunctions arguing prediction market sports bets violate state gaming laws. The tribal argument amplifies the state sovereignty claim.
Industry Coalition
Licensed sportsbooks and casinos operate under state licensing and tribal compacts. They argue prediction markets gain a regulatory arbitrage advantage by operating under CFTC oversight instead.
Policy Allies
IGA has noted growing coalition support from consumer protection organizations who argue CFTC customer protections were designed for institutional derivatives traders, not retail sports bettors.
IGA-NCAI Task Force
The National Congress of American Indians joined the IGA in a formal task force to educate tribal governments and coordinate advocacy surrounding prediction markets and CLARITY Act provisions.
Emerging Allies
Unions representing hospitality workers at tribal and commercial casinos have aligned with tribal interests, citing the risk of job losses if prediction markets divert gaming revenue.

On March 16, 2026, the CFTC published an Advance Notice of Proposed Rulemaking (ANPRM) seeking public comment on regulations that would apply to event contracts traded on prediction markets. The ANPRM posed 40 questions across six categories and closed April 30, 2026.
The IGA prepared model comments for tribes, stating the organization is "not convinced the CFTC is acting in the best interests of Tribal nations" and arguing that any proposed regulation would not adequately address the rapid expansion of what they characterize as unregulated sports betting and the trampling of tribal and state sovereignty.

Gross gaming revenues — reported annually by the National Indian Gaming Commission (NIGC) — fund healthcare, public safety, housing, education, infrastructure, elder services, and cultural preservation programs. Tribal leaders emphasize these are governmental revenues, not commercial profits.

Platform availability could shift
If Congress amends the CLARITY Act to ban sports-event contracts on prediction markets, platforms like Kalshi and others may need to remove or restructure sports markets. Watch the August 2026 Senate window closely.
State restrictions are ongoing
Independent of tribal advocacy, multiple states have active court orders or pending AG lawsuits restricting prediction market access. The tribal argument adds weight to state-level enforcement arguments.
House Agriculture hearing July 21
The House Agriculture Subcommittee holds a hearing on July 21, 2026 examining customer protections and market integrity in sports prediction markets — another pressure point for Congress.
CFTC rulemaking still pending
The CFTC's ANPRM is a precursor to formal rulemaking. Any new rules on sports-event contracts will need to address IGRA, state gaming laws, and the tribal objections raised in public comments.
House Agriculture Hearing: July 21, 2026
Congressional subcommittee examines customer protections and market integrity in sports prediction markets.
