New York prosecutors meet Polymarket over suspicious insider trading bets
Federal prosecutors in New York have met with representatives from Polymarket, a popular prediction market, to discuss how insider-trading laws might apply to suspicious bets.
No charges yet, but the platform has allowed high-stakes bets on big global events, like one trader reportedly bet $30,000 on the kidnapping of Venezuela's president and walked away with more than $430,000.
Polymarket comeback tightens inside information ban
After being banned in 2022 for running without a license, Polymarket made a comeback last year with official approval (November 2025) and introduced stricter rules in March 2026 that ban bets based on inside information or personal influence over outcomes.
Meanwhile, rival platform Kalshi is also under pressure, facing a temporary ban in Nevada and criminal charges in Arizona.
How these cases play out could shape the future of online prediction markets in the US.
