South Korea Takes the Polymarket Fight Off the Streets and Into the Committee Room

Key Points

• South Korea’s Broadcasting, Media and Communications Review Committee has handed Polymarket a window to submit its legal position before regulators decide whether to push forward with a corrective request under gambling legislation.
• Enforcement attention has moved away from individual South Korean users investigated in June, now aimed squarely at the platform’s design, operating model, and compliance structure.
• A ruling against Polymarket could see local internet service providers ordered to block the platform entirely, potentially placing South Korea among the first Asia-Pacific countries to impose platform-level enforcement on a prediction market.

South Korea’s media and communications regulator has pulled the Polymarket dispute onto a different stage entirely, formally opening a platform-level review and deciding to hear the company’s own legal defence before concluding whether its prediction contracts cross the line into illegal gambling.

The Broadcasting, Media and Communications Review Committee confirmed Polymarket would be given a chance to speak for itself. “We decided to provide an opportunity for Polymarket to submit its opinion to thoroughly verify the legality of Polymarket and the way the service is operated,” the committee said, in a statement machine-translated from the original Korean. No corrective order has landed yet; what the committee wants examined, specifically the platform’s legality and the mechanics of how it actually runs, tells you this review is a different animal from the user-level probe that kicked off in June.

South Korea Stops Chasing Users and Starts Questioning the Platform

The order of events is worth paying attention to. On 5 June, the Gangwon Provincial Police opened what was reported as South Korea’s first illegal gambling investigation into domestic Polymarket users, prompted by a request from the National Police Agency. Investigators turned their attention to users who had traded positions during the 3 June South Korean elections, a market that reportedly pulled in hundreds of billions of won.

That earlier probe went after individual people. The committee’s 6 July review goes after the company, and the gap between those two approaches is not procedural. A platform-level corrective request, if the committee decides to issue one, could direct domestic internet service providers to cut access to Polymarket across every South Korean network, leaving no domestic route in.

Attorney An Chang-bo, head lawyer at Respect Law Office and legal representative for some of the users caught in the investigation, did not dress up the legal uncertainty when speaking at the time: “It appears the elements of the gambling offence are met. However, because there have been no cases of punishment for Polymarket use in Korea at all, it is difficult to predict the level of punishment.”

What Korean Law Has Actually Armed Regulators with?

South Korea’s National Gambling Control Commission Act stretches its definition of illegal gaming operations wide enough to catch online services that enable speculative gambling, and it hands regulators the authority to monitor and move against those operations. The Criminal Act stacks further pressure on top of that. A gambling offence draws fines of up to 10 million won, around $6,500. Habitual gambling can bring up to three years in prison or fines of up to 20 million won. Running a gambling venue for profit carries the full weight of the law: up to five years in prison or a 30 million won fine.

Regulators are asking whether Polymarket’s event contracts, the experience they deliver to users, and the way outcomes settle, behave like gambling in practice, regardless of whatever label the platform prefers to put on itself.

Where Polymarket Says It Already Draws the Line?

Polymarket has maintained that its access controls exist to satisfy sanctions obligations, local financial regulations, gambling legislation, anti-money laundering requirements, and Know Your Customer standards. Users in 33 countries are already locked out of the platform, among them those in the United States, United Kingdom, France, Germany, Brazil, Singapore, Japan, and Australia; the restrictions also extend into specific regions within otherwise accessible countries, covering several Canadian provinces and parts of eastern Ukraine.

South Korea does not feature on Polymarket’s published restricted list. Regulators are now weighing whether the platform’s existing geofencing holds up against Korean law, or whether the service has remained accessible in a way that sits in direct conflict with the country’s gambling rules.

South Korea Has Never Had Much Patience for Legal Grey Areas

South Korea’s gambling laws are not written with ambiguity in mind. Outside a narrow band of state-approved products, including horse racing and the government-operated Sports Toto service that caps individual bets at 100,000 won ($65), online gambling is banned. Authorities have spent years pursuing unlicensed offshore operators, and the arrival of blockchain-based platforms has not prompted any change in that posture.

Polymarket received federal regulatory standing in the United States after clearing the Commodity Futures Trading Commission in September 2025 as a designated contract market. Korean regulators have not been impressed. CFTC registration carries no legal standing under South Korea’s domestic framework, and the country evaluates services on what they do in practice, not on credentials issued by another jurisdiction.

Pressure Is Arriving from Multiple Directions at Once

The South Korean review has landed while Polymarket is already navigating a difficult stretch internationally. Bloomberg and CNBC reported that the CFTC is running a wide investigation into Polymarket’s business activities, social media operations included, after the Wall Street Journal reported that the platform pushed simulated trading videos through paid content creators without adequate disclosure. Polymarket told CNBC it had begun auditing its promotional material for compliance.

ESMA issued a public statement on 3 July 2026 putting the industry on notice that some event-based contracts could already sit within the scope of MiFID II, meaning existing retail restrictions on binary options might apply without any fresh legislation required. On-chain research firm Allium separately found that US-linked wallets moved around $571 million in political contracts on Polymarket over the past year, despite the platform’s stated restrictions on American users.

Across the Asia-Pacific region, Polymarket’s growth plans are now running into the same wall its compliance team is facing. The company was reported in May 2026 to be targeting Japanese market entry by 2030, with Mike Eidlin appointed to lead that push. An adverse South Korean ruling would not just complicate that regional strategy; it could hand regulators in Japan, Taiwan, and Singapore exactly the precedent they need to sharpen their own scrutiny of prediction market operators.

No Deadline Set, but the Next Move Belongs to Polymarket

The committee has not announced when it expects to reach a decision. Once Polymarket files its formal response, regulators will work through the company’s legal arguments on both legality and service operation before deciding whether a corrective request goes forward. If the KCSC rules against the platform, the enforcement pathway runs through domestic ISPs rather than through the courts, making it a considerably faster mechanism than any criminal proceeding. Prediction market operators elsewhere tracking this case should understand that South Korea does not need a conviction to cut off access.

Expert Analysis

South Korea moving from individual user investigations to a formal platform review is the development that actually matters here. User-level probes produce individual fines and court appearances. Platform-level corrective requests can erase access for an entire country before any courtroom is involved. Polymarket’s CFTC registration, its main compliance credential in international markets, carries zero reciprocal weight inside South Korea’s legal architecture. The committee’s stated focus on how the service “is operated” points to a functional test being applied: does this product work like gambling, whatever name it goes by? If regulators answer yes, Polymarket does not face a fine; it faces a block. Every other prediction market operator with users anywhere in Asia should be watching what happens next very carefully.
