Polymarket Faces South Korea Block Over Gambling Laws, Setting Asia Precedent
What You Need to Know
- South Korea’s media regulator is considering blocking Polymarket, citing potential violations of gambling laws.
- South Korean law bans nearly all gambling outside state-run channels like horse racing and lotteries.
- Global prediction market trading volume tripled year-over-year to roughly $51 billion in 2025.
- Multiple countries including France, Germany, Italy, and Brazil have already restricted prediction market platforms.
South Korea’s media regulator is weighing whether to block Polymarket, the crypto prediction platform, on the grounds that it may violate the country’s gambling laws. The Korea Communications Standards Commission has invited Polymarket’s operator to submit a formal defense before any decision is made.
The KCSC, which has authority to order internet providers to block sites outright, framed this as due diligence rather than a predetermined outcome. That framing is worth taking seriously, but the regulatory direction is not ambiguous: South Korean law bans nearly all gambling outside state-run channels like horse racing and the lottery, and in June, South Korean police opened the country’s first criminal case targeting local Polymarket users, tracing transactions linked to trading around the June 3 national election. Under Article 246 of the Criminal Act, illegal betting carries fines of up to 10 million won. The KCSC decision will therefore matter well beyond Polymarket itself, because Seoul is one of Asia’s largest crypto markets and whatever framework emerges will likely apply to the entire category of prediction platforms operating there.
Prediction markets have been here before, legally speaking. The argument that these platforms are forecasting tools rather than gambling venues has not moved regulators in France, Germany, Italy, Spain, India, Brazil, Australia, Argentina, or Indonesia, all of which have imposed restrictions.
The stakes are real. Global prediction market trading volume tripled year-over-year to roughly $51 billion in 2025, according to Bernstein data, with some analysts projecting the market could reach $1 trillion by 2030. A South Korean block would not dent those numbers directly, but it would accelerate a pattern where jurisdictions treat crypto-settled event contracts as gambling by default, forcing platforms to either pursue licenses or exit markets. Spain’s Consumer Rights Ministry imposed a temporary ban on both Polymarket and rival Kalshi in May over the absence of gambling licenses, which suggests the licensing path is at least theoretically available, even if no platform has successfully navigated it yet. For investors and traders watching Asian crypto market dynamics alongside broader risk appetite signals, a formal KCSC ruling against Polymarket would mark the first major East Asian regulatory precedent for the category.
Once the commission reviews Polymarket’s formal response, its decision will either open a narrow path toward licensed operation in South Korea or confirm that the gambling label, once applied, is effectively a ban.
