SAN DIEGO – The Indian Gaming Association’s annual convention this week has been dominated by a singular, urgent concern: prediction markets. Tribal leaders, convening in San Diego, have voiced alarm over the rapid expansion of platforms such as Polymarket and Kalshi, perceiving them as an existential threat to the carefully constructed and heavily regulated framework of American tribal gambling.
Tribal gambling enterprises are a cornerstone of Native American economies, generating nearly $44 billion in 2024, a record according to the National Indian Gaming Commission. This substantial revenue directly funds critical social services, including healthcare, housing, and education, across Native American communities. Indian Gaming Association Chairman David Bean has directly accused prediction markets of misrepresenting their offerings to bypass existing federal, state, and tribal laws. “This is no innovation,” Bean stated on Wednesday during a news conference. “This is unlawful gambling dressed up as finance.”
Regulatory Clash Over Market Definition
The core of the dispute lies in how these platforms define their operations. Companies like Kalshi, Polymarket, and Robinhood assert that their users are engaged in futures trading, not gambling, by buying and selling “event contracts.” They argue their products are distinct and should fall under the purview of the Commodity Futures Trading Commission (CFTC), akin to traditional crop or oil markets. The CFTC is currently deliberating new regulations for prediction markets.
Conversely, the Indian Gaming Association contends that these platforms, which allow users to wager on outcomes ranging from the NCAA tournament to geopolitical events, have exploded in popularity and controversy since the 2024 election with minimal oversight. Former National Indian Gaming Commission Chairman Jonodev Chaudhuri described the mood at this year’s convention as one of “collective worry,” noting, “There’s an intensity in the discussions that is more pointed than I’ve seen perhaps ever in these rooms.”
A Hard-Won Economic Foundation
The current structure of tribal gaming is the result of decades of advocacy and legal battles. In the 1970s, during the tribal self-determination era, Native American tribes sought economic tools to alleviate poverty. This led to the emergence of bingo halls and card rooms on reservations. Patrice Kunesh, a fellow at the Brookings Institution, highlights that tribes, limited in their ability to levy taxes, leveraged this new revenue stream to rebuild their governments following prolonged federal control. “Tribes were asserting sovereignty. That rankled the states,” Kunesh explained.
A pivotal 1987 U.S. Supreme Court decision, which blocked California’s attempt to close reservation card rooms, prompted states to lobby Congress for regulatory involvement. This culminated in the 1988 Indian Gaming Regulatory Act (IGRA). Kunesh characterized IGRA as a “compromise for tribes,” a complex regulatory system that expanded the types of gambling tribes could offer, transforming ad hoc bingo operations into sophisticated, multi-billion dollar casino enterprises. The act, however, also imposed stringent standards and mandated that tribes negotiate gambling compacts with states, often requiring revenue-sharing agreements in exchange for exclusivity.
Tribal gambling has historically navigated competitive landscapes. When IGRA passed in 1988, commercial casinos were legal in only two U.S. states; that number has since grown to 27. Today, the industry also contends with legal sports betting in 39 states and the rise of online casinos. However, prediction markets are seen as a unique challenge due to their rapid, seemingly overnight proliferation with limited regulatory oversight.
Legal Challenges and Political Hurdles
In response to this perceived threat, the Indian Gaming Association has called on Congress to impose stricter regulations on prediction markets and has established a defense fund to support legal actions. Already, more than a dozen U.S. states and four tribal nations have filed lawsuits against these platforms in federal court, accusing them of violating federal law and state-tribal compacts.
Among these challengers is the Ho-Chunk Nation, one of 11 federally recognized tribes in Wisconsin with exclusive gambling rights. Ho-Chunk President Jon Greendeer described the situation as a “David and Goliath fight,” with his tribe’s social safety net at stake. “We’re taking on somebody who makes more money on one event than we do in an entire year,” Greendeer stated. The prediction market platforms, in their court filings, maintain they are operating financial markets, not casinos or sportsbooks, and are not conducting business on tribal lands.
The path to congressional action is complicated by the current political climate. The Trump administration has openly supported prediction market platforms, creating hesitancy among lawmakers. “We’re seeing some hesitancy from lawmakers who don’t want to upset the big boss,” Chairman Bean noted. With fewer than half of the nation’s 576 federally recognized tribes offering gambling, and many rural tribal casinos generating just enough revenue to cover basic government operations and social services, the financial impact of unregulated competition is a critical concern. Kunesh underscored that the costs of complying with IGRA, coupled with state revenue-sharing agreements, significantly reduce tribal net revenue, dispelling the misconception that “tribes are making money hand over fist.”
As the Indian Gaming Association initiates studies into the financial impact of prediction markets and marshals resources for potential legal battles, the confrontation underscores a fundamental tension between established, regulated industries and rapidly evolving digital financial products. The outcome of this regulatory and legal struggle will significantly shape the future economic stability of Native American communities and redefine the boundaries of what constitutes gambling in the digital age.
