OKX is reportedly seeking a 20% stake in Coinone, a move that would test South Korea's regulatory stance on foreign exchange ownership.
OKX is reportedly pursuing a 20% equity stake in Coinone, one of South Korea's four licensed won-to-crypto exchanges. The move would give the global exchange a direct foothold in a market where retail trading intensity consistently ranks among the highest worldwide. Coinone holds a real-name account partnership, the regulatory gateway that allows Korean traders to deposit and withdraw won. For OKX, the stake represents a potential shortcut past the licensing wall that has kept most foreign platforms out of Korean won-denominated trading pairs.
South Korea's crypto market is concentrated among four exchanges that operate under the Financial Services Commission (FSC) framework: Upbit, Bithumb, Coinone, and Korbit. Coinone sits third in that group, with a market share well behind Upbit and Bithumb. A 20% stake would not deliver outright control. It would establish a significant minority position and likely include operational influence or technology-sharing arrangements.
Foreign exchanges have struggled to obtain direct licenses. The FSC requires exchanges to partner with a local bank for real-name verification, and it has shown reluctance to approve foreign-controlled entities. OKX's approach mirrors earlier attempts by global platforms to buy into existing licensed venues rather than build from scratch. The strategy reduces licensing risk. It does not eliminate the need for regulatory approval of the shareholder change. Any acquisition of a 20% stake triggers a review under the Act on Reporting and Using Specified Financial Transaction Information, which assesses major shareholder suitability, compliance history, and anti-money laundering controls.
The FSC previously blocked Binance's attempt to acquire a controlling stake in GOPAX, another local exchange, citing governance and compliance concerns. That precedent sets a high bar. OKX has faced regulatory scrutiny in other jurisdictions, a factor that could complicate the review. The outcome will depend on whether the FSC views a 20% minority stake as a passive investment or as a vehicle for foreign operational control.
A green light would signal a shift in regulatory posture toward foreign participation. A rejection would read as a continuation of the protectionist stance that has kept Upbit and Bithumb dominant. The FSC's decision on this specific shareholder change will provide a concrete read on how the regulator balances market access against its mandate to protect Korean users. OKX's compliance record and the structure of the proposed investment will be central to that assessment.
Coinone has been losing ground to Upbit, which commands roughly 80% of Korean won trading volume. A partnership with OKX could bring deeper liquidity, better technology, and access to a broader range of tokens. For OKX, the stake would provide a foothold in a market where the Korean won is often the second-most traded fiat pair for major cryptocurrencies after the US dollar.
The move also fits a broader pattern of consolidation and strategic investment in Korean exchanges. Hana Bank recently took a $670 million stake in Dunamu, the operator of Upbit, signaling that traditional financial institutions see long-term value in the country's exchange infrastructure. OKX's interest in Coinone suggests that foreign exchanges are unwilling to cede the Korean market entirely to local players and their banking partners. The competitive dynamic is shifting from a purely domestic contest to one that includes global capital and technology.
The next concrete marker is a formal filing or regulatory statement from Coinone or the FSC regarding the shareholder change. Until then, the report signals intent rather than a completed transaction. A green light from the FSC would open the door for other foreign exchanges to pursue minority stakes in Korean venues. A rejection would reinforce the framework that has kept local incumbents dominant. Traders tracking the Korean exchange landscape should monitor any regulatory commentary on foreign ownership limits, as that will determine whether OKX's stake becomes a precedent or another blocked attempt.
