Polymarket Adds Deposit Limits, Self-Exclusion Tools as Regulators Seek Crackdown

Polymarket introduced deposit limits and self-exclusion tools on September 30, 2026, as state and federal lawmakers press for regulation of prediction markets. The company also partnered with Birches Health to offer mental health resources for users showing compulsive trading behavior. Users can now set deposit limits that cannot be immediately reversed, place themselves on temporary or permanent exclusion lists, and access virtual gambling addiction therapy. Polymarket's new head of global safety, Malea Otranto, said the company will track usage and may adjust the tools. The measures resemble "responsible gaming" policies at sportsbooks such as DraftKings and FanDuel. Data firm TickerTracker reported sports and parlay markets accounted for more than 98% of trading volume on Polymarket's US site this month. The announcement came one week after New York sued to shut down Polymarket, alleging it circumvents state gambling law. Polymarket denies wrongdoing and filed a countersuit. A bipartisan coalition of 44 states has argued in court that prediction platforms should be regulated like gambling.
