California Tribes Win Order Barring Kalshi Sports Contracts on Their Lands

The ruling turns on a narrow but telling point: Kalshi's self-imposed geofencing was judged insufficient by a court, which suggests voluntary compliance measures may not survive scrutiny when tribal sovereignty and gaming compacts are at stake. This matters most for prediction markets whose growth strategy depends on jurisdictional workarounds, and for tribes defending exclusivity over gaming on their lands. The 21-day compliance report is the near-term signal to watch — whether it reveals technical limits in location blocking, and whether similar challenges follow in other jurisdictions, remains the open question.
