The legal battle between tribal gaming operators and prediction market companies is intensifying in California.
The Indian Gaming Association (IGA) is actively supporting tribes in this fight, emphasizing the threat to tribal sovereignty posed by prediction markets. Three California tribes recently filed a federal lawsuit against prediction market firms Kalshi and Robinhood, accusing them of offering illegal sports betting on tribal lands.
The IGA hosted a webinar titled The New Normal: Prediction Markets in Real Time – What Tribes Need to Know Now, with Victor Rocha, Conference Chair of the IGA tradeshow, highlighting the fast-evolving landscape. And Brian Quintenz, Board Member at Kalshi, appeared before a Senate confirmation hearing to lead the Commodity Futures Trading Commission (CFTC), underlining the significance of these regulatory developments.
Polymarket’s return to the US market is also drawing attention, raising questions about jurisdiction and enforcement.
Jason Giles, Executive Director of IGA, and Chris Gerlacher, Political Analyst with Prediction News, joined Rocha during the webinar, with Rocha stressing the importance for tribes of understanding the current situation and its implications for tribal sovereignty.
Giles criticised the lack of public policy debates on prediction markets, such as wagers on whether Ukraine President Volodymyr Zelenskyy would wear a suit. He recalled how tribal gaming faced stricter scrutiny when it began, while current issues receive less attention from states like Utah and Texas.
Gerlacher highlighted the unusual aspect of the California lawsuit, with Kalshi being a defendant, predicting a “bloody fight” over geofencing reservations and suggesting that lobbying Congress and targeting the CFTC could be potential strategies if legal actions against Kalshi and Robinhood fail.
