Prediction markets could become a larger problem for tribal gaming than a simple hit to casino revenue, according to Kevin Washburn, a Chickasaw law professor and former National Indian Gaming Commission general counsel.
In comments reported by _Tribal Business News_, Washburn said the latest tribal gaming revenue figures may not yet show the full effect because they reflect a period before prediction markets became a meaningful competitive force. He argued the bigger concern is that controversies tied to prediction markets could undermine confidence in legalized gambling more broadly.
Washburn says recent revenue data may understate the issue
Washburn said the latest NIGC revenue report may "disguise the impact a little bit" because much of the period it covers came before prediction markets expanded significantly.
He said he expects prediction markets to reduce tribal gaming revenue, but framed that as only part of the risk. In his view, a larger threat is reputational: if prediction-market scandals emerge alongside sports betting controversies, public backlash may not stay limited to one product category. According to the report, he warned that tribal casinos, commercial casinos, and state lotteries could all be affected if the public loses trust in regulated gambling.
Tribal sovereignty is also at the center of the dispute
Washburn also pointed to sovereignty concerns. He said tribes are worried that prediction markets are being accessed inside tribal casinos even though those activities may fall within exclusive tribal jurisdiction.
The article noted that tribes in New Mexico litigation have presented evidence that people were accessing prediction markets on their phones while inside tribal casinos. Washburn distinguished tribal lawsuits from state challenges by arguing that gaming on Indian lands is governed by the Indian Gaming Regulatory Act.
Supreme Court fight could eventually follow
Washburn said he expects the dispute to move through the federal appeals courts and ultimately reach the U.S. Supreme Court. He said circuit splits are likely.
For California readers, the immediate takeaway is less about a new consumer offering and more about how prediction markets may test the legal boundaries around regulated gambling and tribal gaming. The next key development will be which federal appeals cases move first and whether courts treat these contracts as compatible with existing gambling law on Indian lands.
