Key facts
- South Korea's media regulator has ordered access to Polymarket blocked.
- The platform was classified as an illegal gambling operator under South Korean law.
South Korea's media regulator has ordered access to Polymarket blocked, classifying the crypto prediction market as illegal gambling. The decision follows similar restrictions in other jurisdictions and comes amid broader regulatory scrutiny of digital assets.

The blocking of Polymarket by South Korea highlights the increasing regulatory scrutiny on decentralized prediction markets globally, potentially impacting their accessibility and operation in major economies. The developments also underscore ongoing efforts by US authorities to combat crypto fraud and establish regulatory frameworks for stablecoins.
South Korea's media and communications review commission has ordered access to the crypto prediction market Polymarket to be blocked, classifying it as an illegal gambling environment. The commission stated that Polymarket facilitates gambling under the Criminal Act and prohibited analogous betting activity under the National Sports Promotion Act. Polymarket's winner-takes-all structure, where users gain or lose money based on outcomes of events like politics and sports, was cited as encouraging speculative gambling. The regulator rejected Polymarket's arguments that its decentralized nature, non-custodial transactions, smart contracts, and removal of Korean-language services exempt it from South Korean law. This action places Polymarket alongside over 30 jurisdictions that have previously restricted the platform. In separate crypto news, US prosecutors alleged Edward Zimbardi raised $165 million in crypto through a Ponzi scheme, and the US Treasury advanced proposed rules for the GENIUS Act, a stablecoin law set to take effect in 2027.
