South Korean police have opened an investigation into users of the decentralized prediction market Polymarket on suspicion of illegal gambling. It is the first enforcement action against a platform of its kind in the country.
What the investigation targets
The probe is focused on individuals who used Polymarket, a platform where participants wager on the outcomes of real-world events. Police allege that these activities violate South Korea’s gambling laws. No specific suspects have been named, and the number of users under scrutiny has not been disclosed.
Polymarket and decentralized prediction markets
Polymarket operates on blockchain technology without a central authority, allowing users to trade on the probability of events such as election results or sports outcomes. This investigation marks the first time South Korean authorities have taken action against a decentralized prediction market.
Legal landscape in South Korea
South Korea’s legal framework strictly limits most forms of gambling. The police investigation suggests that trading on prediction markets may be treated as illegal gambling under existing statutes. The case could set a precedent for how decentralized finance platforms are regulated in the country.
What happens next
The investigation is ongoing, and authorities have not yet announced any charges or arrests. The case may lead to broader regulatory scrutiny of blockchain-based prediction markets in South Korea.
