Polymarket users referred to prosecutors in South Korea: Report

South Korean police have reportedly referred 18 Polymarket users to prosecutors in an illegal gambling investigation involving 26 people who collectively wagered about 17.6 billion won (worth $12.7 million). 

According to Asia Economy, data submitted by the National Police Agency to the office of Democratic Party lawmaker Yoon Kun-young showed that the Gangwon Provincial Police Agency had placed 26 people under investigation as of Tuesday and sent 18 of them to prosecutors. The report said the largest amount wagered by a single user was about 5.7 billion won ($4.1 million).

Police identified users by analyzing publicly available blockchain transactions, the report said. Polymarket lets users buy and sell contracts tied to the outcomes of real-world events and operates on a noncustodial, peer-to-peer structure with automated settlement. It does not maintain a conventional list of users by their real names, the report said. 

Authorities reportedly said Polymarket transactions constitute illegal gambling under South Korea’s Criminal Act because users stake assets on outcomes that cannot be predicted with certainty. The users argued that Polymarket should instead be treated as a crypto-based derivatives investment market, according to the report.
