South Korean Police Probe Polymarket Users for Gambling

South Korean police have opened investigations into local users of crypto prediction market Polymarket on illegal gambling charges, according to a June 2026 report by The Block.

Why It Matters

Polymarket users in South Korea now face fines of up to 10 million Korean won (approximately $6,495) if authorities pursue charges. This signals that regulators in major Asian markets are actively scrutinizing decentralized prediction platforms — not just centralized exchanges. For international Polymarket users, the case sets a precedent: operating outside a licensed gambling framework can attract criminal-level consequences even when the platform itself is blockchain-based. Gambling always carries financial risk; regulatory risk now layers on top.

Context

South Korea maintains strict anti-gambling laws that prohibit most forms of wagering outside state-sanctioned operators. Polymarket, a U.S.-based decentralized prediction market running on Polygon, allows users to bet USDC on real-world event outcomes — a model that sits in a legal gray zone across many jurisdictions. As of June 2026, Polymarket has not been licensed as a gambling operator in South Korea.

What's Next

South Korean authorities will determine whether to formally charge identified users, which would clarify how the country's gambling statutes apply to decentralized, crypto-native prediction markets. Any convictions or formal rulings could prompt Polymarket to implement stricter geo-blocking in the region.
