Tribal gaming revenue hits record $46.2bn

• Tribal gaming operations generated a record $46.2 billion in gross gaming revenue during fiscal year 2025, a 5.3% increase over the prior year.
• The total spans 545 gaming facilities run by 246 tribes across 29 states, with seven of the NIGC’s eight regions posting growth.
• The record arrives as prediction markets and sweepstakes casinos increasingly compete for the same players tribal exclusivity was built to protect.

The National Indian Gaming Commission (NIGC) reported a record $46.2 billion in gross gaming revenue for fiscal year 2025, a 5.3% increase over the previous year’s total, according to the commission’s official report.

The figure reflects audited financial statements from 545 tribal gaming facilities operated by 246 tribes across 29 states, and lands at a moment when that exclusivity is under active challenge from outside the regulated framework.

Growth by region

Seven of the NIGC’s eight regions posted gains in fiscal 2025. Sacramento, which includes California, stayed the largest single market at $12.6 billion, up 4.1%.

The D.C. region, covering tribal casinos in New York, Connecticut, North Carolina, Florida, Alabama, Mississippi and Louisiana, grew fastest at 9.8%, adding almost $1 billion to reach $11.2 billion.

Portland climbed 5.3% to $4.9 billion and Phoenix matched that pace to hit $4.2 billion. St. Paul rose 2.9% to $5.3 billion, Oklahoma City added 3.3% to reach $3.7 billion, and Tulsa grew 2.5% to $3.65 billion.

Rapid City was the only region to shrink, dipping 0.9% to $439.8 million.

Concentration risk

The industry’s growth is not evenly spread. Roughly 9% of gaming operations pulled in more than $250 million in GGR for fiscal 2025, and that top tier alone generated more than half of all tribal gaming revenue.

Meanwhile, just over half of the 545 reporting facilities took in less than $25 million each, together accounting for only about 5% of the total.

That split matters beyond bookkeeping. Smaller, rural operations run on thinner margins and have less capacity to absorb a downturn or fund the tribal services their revenue supports, while a handful of large flagship casinos effectively carry the industry’s growth trajectory.

What tribes are defending

Tribal gaming’s federal exclusivity, the arrangement under which tribes hold sole rights to certain gambling activity on their lands in exchange for regulatory oversight, is facing pressure from two directions this year.

California tribes have taken a public stand against dual-currency sweepstakes platforms operating in their backyard as those products expand into markets where tribes hold compacts. Separately, casino industry workers have pressed Congress to rein in prediction markets, arguing the CFTC-regulated products are functioning as unlicensed sports betting and undercutting the compact system tribes rely on.

Some tribes are responding by pushing further into legal mobile wagering rather than waiting on federal action.

Wisconsin’s Senate has advanced a tribal sports betting bill built on a hub-and-spoke model that keeps servers on tribal land, and Minnesota lawmakers have floated a tribal-led framework with an 11-tribe coalition. Both are attempts to lock in mobile market share on tribal terms before it gets contested elsewhere.

Billy Kirkland, Vice Chair of the NIGC, said:

“The continued success of Indian gaming further underscores its importance as a means to support self-sufficiency and strong tribal governments. The agency is proud to work alongside tribal leaders to uphold a regulatory framework that protects these achievements and ensures the benefits endure for future generations.”

Sharon Avery, Associate Commissioner at the NIGC, added:

“I would like to wish the Indian gaming community a job well done on another strong year. These GGR results reflect the continued commitment of tribal regulators and operators to responsible growth and community benefit.”

The record revenue gives tribes a strong hand heading into these fights, but it does not resolve them. The NIGC itself has operated without a Senate-confirmed chair since February 2024, a gap that limits the agency’s capacity to act as a forceful federal advocate just as prediction markets and sweepstakes operators test the boundaries IGRA was designed to hold.

For an industry defined by its exclusivity, the open question is not whether fiscal 2026 will grow, but whether that exclusivity holds long enough to matter.
