South Korean police spent five months identifying individual Polymarket traders via public blockchain transaction records and filed gambling-related cases. The Cyber Investigation Unit of the Gangwon Provincial Police Agency launched the probe in March, opened cases in May, while the Korea Communications Commission (KCC) only ordered the blocking of Polymarket on August 18. As of September 15, police have filed cases against 26 people, with 18 referred to prosecutors. The total amount involved in the case stands at $12.7 million, and the single largest trader invested $4.1 million. South Korean police noted that since Polymarket operates as a non-custodial peer-to-peer market and does not hold a list of South Korean users’ real identities, obtaining a user roster from the operator is not practical. However, on-chain transaction records are publicly available, so the police used open-source intelligence analysis to independently identify and track users.
