The Short Version
On August 18, 2026 the Korea Communications Standards Commission (KCSC) ruled that Polymarket operates a substantively illegal gambling environment under South Korea's Criminal Act and ordered domestic internet providers to block access. polymarket.com no longer opens on Korean connections. This page covers the review timeline, what changes for users, what remains legal, and how to keep following, and practicing, the same markets in Korean from here.

Timeline
May 2026. After a complaint questioning whether Polymarket's yes-or-no betting on real-world events amounts to illegal gambling, the KCSC opens a formal review.
June 2026. The Gangwon Provincial Police Agency launches a criminal investigation into Polymarket users who placed bets connected to the local elections held that month. Participation in illegal gambling carries fines of up to 10 million won (roughly $8,400).
July 2026. Regulators give Polymarket the chance to respond. It argues that its blockchain-based contracts fall outside traditional financial regulation, and points out that it has already removed its Korean-language service and does not support payments in won.
August 18, 2026. The KCSC rejects the peer-to-peer argument, classifies Polymarket as an illegal gambling operator and orders ISPs to block it. Indonesia had blocked Polymarket earlier in 2026; the platform faces restrictions of varying degrees in more than 30 jurisdictions.
The Legal Question
Everything turns on classification. The KCSC read betting on real-world outcomes as gambling under the Criminal Act, and sports markets as illegal sports betting under the National Sports Promotion Act. Polymarket defines itself as a prediction market: the price of a Yes/No contract (0 to 100 cents) is the probability the market assigns to an event, and the counterparty is another user, not the platform. The distinction is not semantic: licensing, tax and consumer protection all change with it. In Korea, however, the KCSC's reading is what applies today.
What Changes for Users
- Access. From domestic networks the site does not load. It is not a browser or wallet problem.
- Funds. The block restricts access to the domain; it is not a seizure. Positions and USDC stay in the on-chain wallet you traded with, and open positions keep resolving under market rules.
- Circumvention. This page does not explain how. Bypassing the block with a VPN breaks Korean law and Polymarket's terms, and the legal and tax consequences are yours.
What You Can Do From Here, Legally
This site is not Polymarket and takes no bets. It is an independent guide that shows the same markets with live probabilities, in Korean, explains them, and lets you practice with a $1,000 virtual account: same markets, same prices, no real money, no wallet. For a Korean reader today it is the simplest way to learn how a prediction market works, from reading the order book to exit strategies, without colliding with the KCSC ruling or Polymarket's terms.
No prediction market is licensed in Korea. Kalshi, the regulated competitor, is available to US residents only.
Why the Korean Case Matters
South Korea is the first major East Asian market to block a prediction market outright, and a rare case of a regulator investigating individual users. That Polymarket had already withdrawn its Korean service did not prevent the decision. How regulators answer the question is a prediction market gambling? will decide the sector's future, and Korea's answer is the firmest yet.
