South Korea has joined a growing list of countries around the globe blocking Polymarket from its population. Korean regulators ordered internet service providers on August 18 to cut off domestic access to Polymarket after classifying its event contracts as illegal gambling. The Korea Communications Standards Commission ruled that the Polymarket platform’s winner-take-all payout model, where results depend on chance outcomes such as elections, sports, and weather, creates a prohibited environment for traders. Officials cited the Criminal Act provisions on facilitating gambling venues and the National Sports Promotion Act rules on analogous activity as the legal basis.
The Telecommunications Deliberation Subcommittee, chaired by Standing Commissioner Kim Woo-seok, approved the block following months of review. Requests from the National Police Agency and the National Gambling Control Commission triggered the examination. In the end, the commission declared access-blocking measures unavoidable to protect local traders from speculative activity tied to events beyond their control.
An earlier police probe into traders active in regional election contracts added momentum to the growing case against Polymarket. Those markets generated substantial notional volume and shifted official attention from prohibitions on individual contracts to platform-wide controls.
Rejection of Non-Custodial Claims and Platform Defenses
Polymarket submitted materials arguing that it had removed Korean-language services and does not accept local Korean fiat payments. The platform stressed its non-custodial peer-to-peer transactions and smart contracts, which avoid direct handling of trader funds. Commission members dismissed these points, stating that technical features such as decentralization, trading interfaces, and order books cannot override domestic law.
They noted that Polymarket still creates markets, sets rules, provides crypto deposit and withdrawal systems, and collects fees. Locally focused contracts, including those tracking precipitation levels within South Korea, served as further evidence of targeting Korean users. The winner-take-all structure was deemed to foster the same speculative mindset that existing gambling statutes prohibit.
The platform offered no immediate public comment after the vote. Its earlier submissions formed the core of the defense, yet they failed to alter the outcome. That has been the pattern in other country prohibition cases as well. Traders now face a practical barrier as providers execute the shutdown order.
Expanding Global Restrictions and Trader Impact
This decision places the jurisdiction among more than 39 other nations that have already limited access to Polymarket due to gambling concerns and competition with local purveyors. France directed providers to block the site in mid-July, while Australia and Germany acted earlier, citing risks of trader losses and potential manipulation. Reporting across outlets confirmed the pattern of shrinking availability for crypto-settled outcome contracts.
Traders seeking these markets face tightening access and potential shifts in liquidity. The consistent focus across rulings remains the winner-take-all design combined with real financial stakes. Platforms operating under similar mechanics may encounter parallel reviews as authorities prioritize user protection.
Coverage from specialized publications captured the sequence from subcommittee review to final vote. The dual citation of criminal and sports promotion statutes strengthened the order. Looking ahead, operators and traders will monitor any further clarifications as they adapt to the new limits on cross-border participation.
