Digital asset exchange OKX and brokerage firm Korea Investment & Securities are engaged in formal negotiations to acquire a 20% stake in Coinone. The acquisition structure relies on the issuance of new corporate shares by the South Korean exchange, a mechanism designed to inject direct liquidity into the company’s balance sheet without requiring the sale of positions held by current majority shareholders.
This technical configuration maintains the governance structure and administrative control within the existing board while integrating institutional capital. The details of the negotiation were disclosed on May 15, 2026, through a Yonhap News agency report, specifying that the foreign entity seeks direct access to liquidity channels on the Asian continent.
The South Korean cryptocurrency market operates under a restrictive licensing system where only five platforms hold legal authorization to process fiat transactions denominated in won: Upbit, Bithumb, Coinone, Korbit, and Gopax. The entry of international corporations into this commercial circuit faces significant hurdles due to stringent corporate compliance requirements. Unable to process independent operational permits in the short term, foreign trading venues resort to acquiring minority stakes in established infrastructures that already maintain active agreements with local commercial banks for account verification.
The distribution of investment percentages between OKX and Korea Investment & Securities responds to an ongoing legislative transition. Regulatory bodies in the Asian country are currently structuring legal frameworks focused on preventing financial monopolies. Currently, the legislative assembly is evaluating the implementation of 15-20% ownership caps for cryptocurrency exchange holdings, aiming to fragment systemic risk and ensure administrative transparency. This projected limitation aligns with the exact percentage the global exchange seeks to acquire in its foray into the peninsula.
The potential capital injection into Coinone occurs weeks after government intervention regarding the company’s risk frameworks. On April 13, 2026, the South Korean Financial Services Commission (FSC) executed a $3.5 million financial penalty against the platform and ordered a three-month partial business suspension. Authorities based the punishment on severe deficiencies within the internal anti-money laundering (AML) prevention systems, specifically pointing to a lack of rigor in identity verification controls for retail clients.
Government audits detected that Coinone’s infrastructure processed transaction volumes linked to foreign platforms operating without the corresponding commercial registration within the South Korean jurisdiction. The financial watchdog issued strengthened oversight guidelines to compel the restructuring of internal audit departments across all active virtual asset exchanges. The operational penalty from April requires the platform to rectify its cross-border transaction filters before resuming the entirety of its business lines.
Institutional consolidation in the local market
While foreign platforms negotiate minority positions, domestic financial conglomerates are accelerating the vertical integration of blockchain infrastructures through direct purchases. Hana Financial Group announced on Friday, May 15, 2026, a strategic capital deployment to integrate digital settlement operations. The banking corporation committed an investment of 1.003 trillion won, equivalent to $668 million, to acquire a 6.55% position in Dunamu Inc., the operating company of the Upbit exchange, thereby consolidating its exposure in the country’s highest-volume crypto trading entity.
This corporate absorption trend recorded its most aggressive movement during the first quarter of the year. In February 2026, consulting and capital management firm Mirae Asset agreed to purchase a 92.06% stake in Korbit, disbursing a total of 133.48 billion won, a figure hovering around $93 million. Unlike the minority positions negotiated by OKX and Hana Financial, the Mirae Asset operation transferred absolute operational control of the platform to the traditional financial corporation.
The current negotiations for fractional control of Coinone follow a market exploration phase initiated by North American competitors. During January of this year, the exchange Coinbase evaluated a capital deployment into the South Korean company while majority shareholders explored partial sale alternatives, though the conversations did not culminate in a definitive corporate agreement.
The official closing of the share transaction between Hana Financial Group and Dunamu Inc. is scheduled for the second week of June 2026.
