Polymarket is facing another international roadblock after South Korea moved to restrict access to the prediction market platform over concerns that it violates the country's gambling laws. South Korea's media and communications regulator approved the action after reviewing how Polymarket operates, including its market structure, trading rules, and crypto-based settlement system. The decision puts South Korea alongside a growing list of jurisdictions that have decided Polymarket's prediction market model does not fit within existing local rules.
The move also highlights a challenge that is becoming difficult for major prediction market operators to ignore. A platform can operate across borders almost instantly, but regulations remain very local. If you are building a global prediction market, that difference can quickly become a serious headache.
South Korea Wasn't Sold on Polymarket's Defense
Polymarket reportedly made several arguments for why the platform should not be treated as an illegal gambling operation in South Korea. The company pointed to its removal of Korean-language services, lack of support for payments in Korean won, and use of noncustodial transactions and smart contracts. Regulators were not convinced. South Korean officials focused more heavily on what users actually do on the platform.
The commission said Polymarket still creates and manages markets, sets trading rules, facilitates crypto deposits and withdrawals, runs settlement systems, and collects transaction fees. That distinction could matter well beyond this particular case. Regulators essentially looked past the technical structure and focused on the underlying product experience.
Polymarket's Restricted Map Keeps Getting Bigger
South Korea is hardly alone. More than 30 jurisdictions have now reportedly restricted Polymarket in some form, while Polymarket itself currently lists 39 countries as fully restricted. France, Spain, Indonesia, Argentina, and Ukraine are among the countries that have previously taken action. A few details from the South Korean decision stand out:
- Regulators began reviewing Polymarket in July.
- The review followed requests from South Korea's National Police Agency and National Gambling Control Commission.
- Authorities rejected Polymarket's argument that its peer-to-peer structure changed its legal status.
- South Korea was not yet included on Polymarket's own list of fully restricted countries following the decision.
The growing list creates a complicated international puzzle. Prediction markets might be digital products, but where you physically live increasingly determines which platforms and markets you can access.
Global Expansion is Getting More Complicated
Polymarket's regulatory situation also shows how different its international challenge is from the fight playing out inside the United States. U.S. disputes have largely centered around whether federal commodities regulation overrides state laws. South Korea does not have to work through that same federal-versus-state question.
Instead, South Korean authorities evaluated Polymarket under their own national laws and decided to block the platform. Similar decisions elsewhere could force Polymarket to approach expansion country by country rather than treating international availability as one giant market.
That becomes especially important as prediction markets grow beyond their political roots. Sports, economics, entertainment, weather and other event categories give platforms more ways to attract users, but every additional category can also create new regulatory questions.
The Trade Handle Prediction Markets Take
We have spent plenty of time watching the prediction market regulatory fight develop across the United States, but Polymarket's international problems deserve just as much attention. South Korea joining the list of restricted jurisdictions shows that regulatory questions surrounding prediction markets are becoming increasingly global.
The bigger issue is whether other countries follow a similar approach. South Korean regulators were not persuaded that smart contracts, noncustodial transactions, or a peer-to-peer structure fundamentally changed what Polymarket offers users. If that reasoning spreads, Polymarket could find that building a truly global prediction market requires navigating dozens of very different regulatory systems rather than finding one legal structure that works everywhere.
