Tribal leaders stormed Capitol Hill Tuesday with a blunt warning: new sports event contracts traded on prediction markets could wipe out billions in revenue that funds essential government services on Native American reservations across the country.
The Indian Gaming Association delivered that message during a packed congressional briefing in the Senate Committee on Indian Affairs room, calling the fast-growing financial products the single largest danger to tribal gaming since Congress passed the Indian Gaming Regulatory Act in 1988.
These contracts let people bet on the outcome of real sporting events such as “Will the Kansas City Chiefs beat the spread against the Buffalo Bills next Sunday?” through platforms regulated by the Commodity Futures Trading Commission instead of state gaming commissions.
Two companies, Kalshi and PredictIt, already list dozens of these contracts. Tribal leaders say they are nothing more than illegal sports bets dressed up as futures contracts to dodge federal and state gambling laws.
Ernie Stevens Jr., chairman of the National Indian Gaming Association, told lawmakers the products directly compete with legal sportsbooks operated by tribes in 28 states. He warned that money flowing to Wall Street platforms will starve tribal health clinics, schools, and housing programs.
The Money at Stake Runs into Billions
Indian gaming generated $41.9 billion in revenue last year, according to the National Indian Gaming Commission. Much of that money replaces missing federal funding on reservations.
- California tribes alone sent more than $1 billion to state and local programs through revenue-sharing deals
- Oklahoma tribes fund 12,000 jobs and pay hundreds of millions in exclusive fees to the state
- Connecticut’s two tribal casinos contribute 25% of slot revenue straight to state coffers
If bettors shift even ten percent of their action from tribal sportsbooks to unregulated prediction markets, tribes could lose hundreds of millions every year.

How the CFTC Became the Surprise Battleground
The fight exploded last year when the CFTC approved Kalshi to offer election contracts and later sports contracts. A federal appeals court overturned an earlier block, opening the door wide.
Tribal leaders argue the commission overstepped its authority. The Commodity Exchange Act clearly bans wagering on elections and sporting events. They say the CFTC simply re-labeled gambling as “hedging” to justify the move.
Mark Macarro, chairman of the Pechanga Band of Luiseño Indians, put it plainly: “This is not hedging corn prices or oil futures. This is people betting on the Super Bowl with no guardrails and no revenue coming back to states or tribes.”
Lawmakers Promise Action, But Clock Is Ticking
Several members of Congress attended the briefing and left visibly concerned. Senator Maria Cantwell of Washington and Senator Tina Smith of Minnesota both pledged to look for legislative fixes before the markets grow larger.
Industry sources say Kalshi already has contracts worth tens of millions of dollars trading daily, and more platforms wait in the wings.
A growing coalition now pushes for a simple solution: Congress must close the loophole by banning event contracts on sports and elections once and for all.
| Issue | Tribal Sportsbooks | Prediction Market Contracts |
|---|---|---|
| Regulated by | State gaming commissions | CFTC |
| Revenue sharing | Yes – funds tribal & state programs | No |
| Age verification | Strict 21+ with ID checks | Often weaker |
| Problem gambling tools | Mandatory limits and self-exclusion | Limited or none |
| Tax revenue for states | Hundreds of millions yearly | Zero |
The contrast could not be clearer.
The tribal gaming industry has spent 35 years building a tightly regulated system that lifted many Native communities out of poverty. Leaders say they will fight with everything they have to protect it.
As Chairman Stevens closed the briefing, his voice carried the weight of generations: “We have survived termination, relocation, and broken treaties. We will not let Wall Street take away the one economic engine Congress promised would always belong to tribal nations.”
