South Korea reviews whether Polymarket is illegal gambling
The Korea Communications Standards Commission is reviewing Polymarket amid concerns the service could constitute illegal gambling under South Korean law.
According to a report by local media outlet Bloomingbit, the commission – which undertook the review after receiving a complaint – will explore whether Polymarket can be classified as illegal gambling and whether it can be deemed to encourage gambling. It also will look at other overseas regulatory cases to see how they have handled the prediction market dilemma.
The outlet noted that Polymarket is available in South Korea and offers a Korean-language service. This in itself could put it directly under the commission’s purview if it is seen as targeting Korean users, even if servers are elsewhere.
After the massive but controversial growth of prediction markets in the United States, a number of countries have deemed Polymarket to be an illegal gambling platform and blocked access, including France, Germany, Italy, India, Brazil, Ukraine and Argentina. In Asia-Pacific, Singapore, Thailand, Australia and New Zealand are among those to have taken definitive action.
Polymarket has famously faced regulatory issues in the United States, where the U.S. Commodity Futures Trading Commission in early 2022 charged its parent company with operating an unregistered trading platform and failing to register as a Designated Contract Market (DCM) or Swap Execution Facility (SEF).
After settling the case, winding down non-compliant markets and geo-blocking American users, Polymarket has since 2025 slowly re-entered the US market under a regulated structure and with CFTC approval.

The Backstory
How a niche market landed in Seoul’s crosshairs
South Korea’s review of Polymarket is the latest turn in a fast-evolving fight over what counts as gambling in the digital age. The Korea Communications Standards Commission opened a case after a complaint flagged the platform’s availability in Korean and its localization for domestic users — factors that could bring it squarely under the commission’s remit if they are seen as targeting residents. The commission is studying whether the site constitutes illegal gambling and whether it promotes gambling activity. It also plans to examine how overseas regulators have handled similar products, according to a report by Bloomingbit.
Polymarket sits at the intersection of decentralized finance, event contracts and speculative wagering, which different jurisdictions have treated in different ways. In the United States, the platform’s owner settled charges in 2022 with the Commodity Futures Trading Commission for operating an unregistered trading venue, then wound down noncompliant markets and geofenced users before gradually reentering the U.S. in 2025 under a more regulated framework. Elsewhere, the service has been blocked or curtailed entirely. That patchwork is the backdrop for South Korea’s inquiry and helps explain why regulators are focused as much on access, language and marketing as on product design.
The stakes are high. Any determination that a prediction market is gambling under Korean law would put operators and users at risk of enforcement, extend content-blocking to offshore sites deemed to be targeting Koreans and harden the compliance expectations for foreign platforms offering Korean language or payments. A softer read could still trigger labeling, warnings or tighter know-your-customer checks. Either way, the decision is likely to ripple across crypto-adjacent apps and other “financialized” content vying for mainstream users.
Crackdowns shaped by a pivot to digital crime
The Polymarket review does not come in isolation. Police and lawmakers have been racing to catch up with a surge in online gambling and cyber-enabled fraud, as organized crime groups redirect talent and capital from street-level rackets to clicks and code. For the first time, South Korean gang arrests are now skewed more toward internet offenses than traditional crimes. In 2024, 56.3% of the 2,363 organized crime members arrested were tied to digital crimes such as illegal igaming, outpacing extortion and assault, according to police data cited in an analysis of arrest patterns.
That shift matters for regulators weighing whether prediction markets encourage gambling. The more criminal groups migrate online, the stronger the case for proactive content controls, local blocking and cooperation with foreign platforms. Police say younger gang members in their 20s and 30s are fueling the pivot, using encrypted messaging, burner phones and digital payment rails to monetize at scale. Those methods bleed into adjacent online niches — marketing, streaming and social chat — and complicate the line between gray-market speculation and outright gambling.
Cross-border operations test the limits of enforcement
South Korea’s law-and-order push spans borders, reflecting how online betting outfits move servers, staff and payments across Southeast Asia. In one of its broadest operations, the National Police Agency repatriated 49 suspects from the Philippines in cases tied to fraud, cybercrime and illegal online casinos. The group included alleged operators in a multitrillion-won casino ring dating to 2018. Authorities described the transfers as a milestone in international policing and a warning to operators who believe distance or jurisdictional arbitrage insulates them from Korean law. Details are outlined in a report on the Philippines repatriations.
Domestically, investigations have exposed sprawling networks with offshore infrastructure and local user funnels. Police in South Chungcheong dismantled an eight-site operation based in the Philippines, Vietnam and Cambodia that allegedly pushed real-time betting through Telegram and splashy promotional designs. The group is accused of handling more than KRW530 billion in wagers and pocketing at least KRW27.1 billion over five years before 32 suspects were arrested, including the alleged ringleader. The probe began when teens were found hired to spam promotional messages — a telling conduit for illicit sites seeking scale. The case and the enforcement posture that followed are detailed in a breakdown of the igaming network takedown.
These cases illustrate why accessibility — language settings, local payments, social media presence — has become a regulatory trigger. When a platform offers Korean-language services, authorities are more likely to view it as targeting domestic users, regardless of where servers sit. That lens could shape how the commission interprets Polymarket’s footprint and decides whether to order access blocks or coordinate with financial regulators.
Growing youth exposure sharpens the policy response
A parallel concern driving scrutiny is the spike in gambling exposure among teens. Treatment cases for adolescent gambling addiction tripled in two years to 210 in 2024, while police logged a sharp rise in gambling offenses involving minors, according to lawmaker data. Online casinos and illegal sports betting accounted for much of the surge, with first contacts often via sports sites and social platforms. These trends, and calls for prevention alongside crackdowns, are summarized in a review of youth addiction data.
Financial institutions have joined the push, framing youth igaming as a systemic risk. Hana Bank President Lee Hosung publicly backed a relay campaign warning that “illegal online gambling targeting youth is a scam you can never win,” and nominated another bank chief to continue the initiative. Hana Financial Group’s Dodo Project, launched in 2024, targets prevention and treatment in coordination with national agencies. The sector’s involvement signals that any policy outcome on prediction markets will be judged not just on market innovation, but on spillovers to households and vulnerable users. The campaign and its context are laid out in coverage of the banking sector’s role.
What regulators will weigh next
The commission’s review is expected to test three questions. First, does a prediction market offering in Korean and accessible domestically meet the legal threshold for gambling, especially if real money is staked on event outcomes outside of financial hedging? Second, do product design and marketing encourage gambling behavior under Korean standards, particularly for younger users? Third, how have peers ruled, and what lessons travel to Korea’s setting? With countries from France to Brazil blocking access and others imposing conditional permissions, Seoul has latitude to calibrate between outright prohibition and controlled access.
Officials also are likely to consider enforcement practicality. Recent cases show authorities can reach overseas operators through joint work with neighboring governments and Interpol, but day-to-day deterrence still leans on domestic content blocks, payments friction and platform cooperation. The prediction market dilemma adds a capital markets twist: if a product resembles a derivatives venue, financial regulators may assert jurisdiction; if it’s deemed gambling, content and criminal statutes take the lead. That gray area — exposed by U.S. actions that pushed one platform to alter its market design and compliance — will inform Seoul’s path.
Whatever the decision, the signal will be loud. A finding of illegality would align South Korea with jurisdictions that have cordoned off prediction markets as gambling and could trigger broad access blocks and targeted investigations. A measured approach might permit limited, registered offerings with strict safeguards. Either way, the combination of organized crime’s digital pivot, cross-border enforcement and rising youth exposure has narrowed the window for regulatory ambiguity.
