Polymarket is accessible in South Korea — the platform does not geoblock Korean IP addresses. South Korea is one of the world’s most active crypto markets, with over 15 million crypto holders and exchanges that dominate global trading volume. However, Korea’s strict gambling laws create a legal grey area for prediction market participation. Here’s what Korean users need to know.
Current Status: Accessible
South Korea is not on Polymarket’s geoblocked countries list. The platform is fully accessible from Korean IP addresses. Korean users can sign up, deposit, and trade on any available market.
South Korea has one of the highest crypto adoption rates in the world — roughly 30% of the population holds digital assets. The “kimchi premium” (the price gap between Korean and global crypto markets) is a well-known phenomenon that reflects the intense demand for crypto among Korean traders. Stablecoin trading volume across Korea’s five major exchanges hit KRW 57 trillion (approximately $42 billion) in Q1 2025 alone, with Korean traders regularly using stablecoins like USDC to access international platforms.
That said, South Korea’s gambling laws are among the strictest in Asia, and prediction markets like Polymarket exist in a legal grey area. While not specifically addressed by regulators, Korean users should be aware of the potential legal implications.
The Legal Landscape
Gambling Laws
South Korea takes a hardline approach to gambling. Under Article 246 of the Criminal Act, gambling is illegal except in narrowly defined exceptions: state-run lotteries, a limited number of authorized casinos (mostly for foreigners), and legal sports betting through the Korea Sports Promotion Foundation.
Key points:
- Online gambling is explicitly banned for Korean nationals
- Penalties include fines of up to 10 million KRW and, for habitual gambling, up to 3 years in prison
- Korean gambling laws apply extraterritorially — Koreans can technically be prosecuted for gambling abroad under the Habitual Overseas Gambler Law
- Authorities actively block access to offshore gambling sites and have intensified enforcement in recent years
Prediction Markets
Prediction markets have not been specifically classified by Korean regulators. During the 2025 constitutional court impeachment ruling on then-president Yoon Suk Yeol, a wave of prediction market betting swept the country, drawing regulatory attention. Authorities have shown willingness to order ISPs to block gambling sites, restrict payment rails, and remove apps from official stores.
Whether Polymarket — as a decentralized, crypto-based platform — would be treated differently from traditional gambling sites remains untested in Korean courts.
Crypto Regulation
South Korea’s crypto regulatory framework centers on the Virtual Asset User Protection Act (VAUPA), enacted in 2023 and actively enforced since 2024:
- All crypto exchanges operating in Korea must register with the Financial Intelligence Unit (FIU)
- In 2025, the FIU blocked 17 unregistered foreign exchanges (including KuCoin and MEXC) for violating the Special Financial Transactions Act
- The long-awaited Digital Asset Basic Act (DABA) has been delayed amid disputes over stablecoin regulation, with legislative introduction now expected in 2026
- The Financial Services Commission (FSC) oversees market regulation, while the National Tax Service (NTS) handles crypto taxation
How to Deposit from South Korea
South Korea has a mature crypto exchange ecosystem with direct KRW support and strong banking partnerships. Stablecoins are the preferred method for Korean traders accessing international platforms.
Step 1: Buy USDC on a Korean Exchange
| Exchange | KRW Deposit | Banking Partner | Notes |
|---|---|---|---|
| Upbit | Bank transfer | K-Bank | Largest Korean exchange by volume; 0.05% trading fees |
| Bithumb | Bank transfer | KB Kookmin Bank | Second-largest; 0.25% base fee with tier discounts |
| Coinone | Bank transfer | Kakao Bank | Strong mobile integration |
| Korbit | Bank transfer | Shinhan Bank | One of Korea’s oldest exchanges |
| Gopax | Bank transfer | Jeonbuk Bank | Smaller but regulated |
All major Korean exchanges require real-name verified bank accounts linked to the exchange. This is a regulatory requirement — you’ll need a Korean bank account with the exchange’s partner bank to deposit KRW.
Step 2: Transfer USDC to Polymarket
- Go to Deposit on Polymarket
- Select Use Crypto and copy your deposit address
- Send USDC from your Korean exchange to the Polymarket address
- Choose Polygon for the lowest fees ($3 minimum, arrives in seconds)

Important Notes for Korean Users
- Korean exchanges require real-name verification (KYC) with a Korean phone number and ID
- You’ll need a linked bank account with the exchange’s specific partner bank
- Stablecoin withdrawals from Korean exchanges are standard — USDC on Polygon is widely supported
- The “kimchi premium” means crypto prices on Korean exchanges may differ slightly from global prices
Tax Implications
South Korea’s crypto tax situation is unusually favorable — for now.
Current Status: No Crypto Capital Gains Tax (Until 2027)
The planned 20% tax on virtual asset gains has been postponed three times:
- Originally scheduled for 2023
- Delayed to 2025
- Delayed again to 2027
As of March 2026, crypto trading profits are not subject to capital gains tax in South Korea. This includes profits from platforms like Polymarket.
What’s Coming in 2027 (Potentially)
The proposed tax framework includes:
- 20% tax (plus 2% local income tax = 22% effective rate) on annual crypto gains exceeding 2.5 million KRW (approximately $1,800)
- Applies to gains from virtual asset transfers and rentals
- South Korea has signed the OECD’s Crypto-Asset Reporting Framework (CARF), which requires 48 countries to share crypto transaction data starting in 2027
However, many analysts expect a fourth delay. Significant infrastructure gaps remain — authorities have not established systems for transaction monitoring, income classification, or cross-border enforcement. The opposition party has pushed to scrap the tax entirely.
Other Tax Considerations
- Income tax on crypto may apply if trading is classified as business income (progressive rates of 6-45%)
- Gift tax applies to crypto transferred between individuals
- Keep detailed records of all deposits, trades, and withdrawals regardless of the current tax-free status
