US Tribal Gaming Hits Record $46.2B, Eyes New Threat

Fact Checked

A record $46.2 billion year, set while the threat tribes fear most was already operating. The worry is what comes next.

US tribal gaming posted a record $46.2 billion in gross gaming revenue in fiscal 2025. That marks a 5% rise on the prior year. The National Indian Gaming Commission released the figures on Tuesday. They cover 545 facilities run by roughly 250 tribes across 29 states. According to the NIGC, tribal gaming has now set a GGR record every fiscal year since 2011, bar the 2020 pandemic year. However, the celebration carries a warning. Tribal leaders say prediction markets threaten future growth. Several tribes have already taken those operators to court.

A Record Year for Tribal Gaming

The scale of tribal gaming surprises many. At $46.2 billion, the sector dwarfs individual commercial markets. For context, the Las Vegas Strip produced $5.5 billion in the same period. One NIGC region alone beat the entire Strip several times over. According to the commission, tribal gaming underpins sovereign tribal governments. It funds community investment and essential services for tribal citizens. So the revenue is not shareholder profit in the usual sense. It flows into government budgets, health, and education. That framing shapes how tribes view any threat to it. NIGC leaders described the results as reflecting responsible growth and community benefit. The 15-year record streak, broken only by Covid, shows durable demand. However, past performance guarantees nothing about a market facing new competition. The record was also set under specific conditions that are now changing. Comparable market-scale context features in our report on the 2026 online casino market.

Where the Growth Came From

Growth was broad rather than concentrated. Seven of the NIGC’s eight regions grew year-on-year. Only the Rapid City region, covering the Dakotas and nearby areas, slipped, and by under 1% to $439.8 million. The Sacramento region led as usual, spanning California and northern Nevada. It produced a striking $12.6 billion, up 4%. That single region out-earned the Las Vegas Strip more than twofold. The Washington DC region grew fastest at 10%, reaching $11.2 billion. Despite its name, it covers most of the east coast from Florida to New York. Oklahoma, split into two NIGC regions, remains a tribal stronghold. The Oklahoma City and Tulsa regions each produced $3.7 billion, up 3% and 2.5%. Other regions posted steady mid-single-digit gains. St. Paul reached $5.3 billion, Portland $4.9 billion, and Phoenix $4.2 billion, each growing 3% to 5%. So the record rested on wide participation, not one runaway market. However, that breadth may not insulate the sector from a national-scale competitor.

The Prediction Markets Threat

Tribes see prediction markets as an existential risk. Gaming tribes across the US have united against the platforms. That opposition has reached the courts. Tribes in California, Wisconsin, and New Mexico have sued prediction-market operators. According to the lawsuits, the platforms violate the Indian Gaming Regulatory Act and state gambling compacts. The revenue stakes are framed dramatically. James Siva, chairman of the California Nations Indian Gaming Association, said early estimates suggest prediction markets have already siphoned about 5% of tribal gaming revenue. He warned that unchecked expansion could mean a 25% GGR loss within a year. However, these figures come from a tribal-association leader actively opposing the platforms, and warrant caution. The source itself notes the impact has not yet appeared in revenue data. The record FY25 was set even though prediction markets grew from late 2024, roughly halfway through the fiscal year. So the projected losses are advocacy warnings about the future, not measured results. That distinction matters when weighing them. Similar classification fights feature in our reports on the Dutch Polymarket ruling and Google’s ad ban. Trade coverage of the dispute, including AGBrief, tracks the litigation.

A Regulator Under Strain

The tribes’ regulator is itself under pressure. The NIGC is the only federal body dedicated solely to tribal gaming. However, it has lacked a confirmed chair or a full three-commissioner roster since February 2024. That was when longtime chairman Sequoyah Simermeyer left to join FanDuel. Commissioner Sharon Avery served as acting chair, then returned to an associate role in January. Billy Kirkland was sworn in this year, replacing a departed vice chair. According to the report, President Trump has not nominated a new NIGC chair since taking office in January 2025. So the commission oversees a record-setting sector while missing its top leadership. It also closed seven regional offices last November. As a result, some in the industry question its current effectiveness. That governance gap arrives at an awkward moment. The sector faces its most serious competitive threat precisely as its regulator runs short-staffed. At a House subcommittee hearing this week, Indian Gaming Association chairman David Bean criticised the Commodity Futures Trading Commission, accusing it of being captured by private interests and raising concerns about youth access to prediction markets. The hearing was balanced, including testimony from a former CFTC general counsel. The prediction-market regulatory questions sit in our iGaming trends 2026 report.
