South Korea has cut off access to Polymarket, the crypto-based prediction market, adding itself to a list of more than 30 jurisdictions that now restrict the platform. Regulators in Seoul rejected the company's argument that it operates purely as a peer-to-peer network, ruling instead that Polymarket actively manages market rules and enables crypto-facilitated gambling.
Why the P2P defense fell flat
Polymarket had leaned on its peer-to-peer structure, arguing it was simply a venue where users traded on outcomes. South Korean authorities didn't buy it. They pointed to the platform's role in setting market parameters, resolving disputes, and collecting fees—hardly the hands-off posture of a passive network. In their view, that makes Polymarket an operator, not a middleman, and the activity on it gambling with crypto assets.
The decision mirrors a growing pattern. Regulators across Europe, Asia, and the Americas have reached similar conclusions, and the list of blocked jurisdictions keeps growing.
What changes for South Korean users
From here, Polymarket is effectively off-limits to users in South Korea. The restriction follows a familiar playbook: access blocked, accounts frozen, and any remaining balances subject to withdrawal rules. The platform hasn't said how it will handle existing positions or funds held by South Korean users, but the window for new bets is shut.
This isn't just one country acting alone. With South Korea's move, the tally of restricted jurisdictions now exceeds 30. That's a lot of friction for a platform that once positioned itself as a borderless arena for predicting everything from elections to sports outcomes. The regulatory tide has turned, and the debate over whether prediction markets count as gambling or legitimate forecasting is being settled by governments, one by one.
For now, Polymarket's options look thin. It can appeal the decision, but similar fights elsewhere haven't gone its way. The next step is likely a formal response from the company, though none has been announced. South Korea's enforcement date also hasn't been spelled out publicly—so users are left waiting, and the platform is left with fewer markets to serve.
