Polymarket and Montana gambling law
Montana runs its sports betting through the state lottery's Sports Bet Montana system, one of the more restrictive models in the country. That makes an independent prediction-market app a meaningfully different option for residents.
Polymarket offers its prediction markets to eligible Montana residents via the app, subject to identity and location verification.
Eligibility is confirmed at sign-up, and Montana residents should review the current in-app terms before trading.

The court sent Nevada's challenge to election contracts back to the district court.
