OKX Ventures has acquired an approximately 20% stake in South Korean cryptocurrency exchange Coinone, becoming a joint third-largest shareholder in one of Asia’s most active and tightly regulated digital asset markets.
The investment arm of global crypto exchange OKX is taking the minority position alongside Korea Investment & Securities, one of South Korea’s largest brokerage firms. Earlier reports said OKX Ventures and Korea Investment & Securities would each invest about 80 billion won, or roughly $53 million, for stakes of approximately 19.6% in Coinone. More recent Korean reporting said OKX had been added as a new shareholder with a 20% equity stake.
The transaction is structured through a combination of secondary share purchases from existing shareholders and subscriptions for newly issued shares. After the deal, Coinone founder and chief executive Cha Myunghun is expected to remain the largest shareholder and retain management control. Com2uS Holdings and its affiliates remain the second-largest shareholder group, while OKX Ventures and Korea Investment & Securities become joint third-largest shareholders.
Strategic Entry Into South Korea
The investment gives OKX a direct foothold in South Korea, a market known for deep retail participation, high trading intensity and strict licensing requirements. South Korean crypto exchanges operate under the country’s virtual asset service provider regime and must maintain banking partnerships, real-name account systems and anti-money-laundering controls.
For OKX, buying into Coinone offers exposure to a licensed domestic platform without attempting to build a standalone Korean exchange from scratch. That is strategically important because South Korea remains one of the world’s most active crypto markets, but local regulation has made direct offshore competition difficult.
Coinone is one of South Korea’s major crypto exchanges, though it remains smaller than market leader Upbit. The new capital and strategic partnerships are expected to support upgrades to trading infrastructure, compliance systems, custody, wallet services and institutional products. Korean reports said Coinone plans to combine OKX’s global trading and infrastructure capabilities with Korea Investment & Securities’ traditional finance expertise.
The involvement of Korea Investment & Securities also broadens the strategic value of the deal. The brokerage has shown interest in stablecoin-related services and tokenized securities, two areas South Korean policymakers are preparing to regulate more actively. Coinone could therefore become a bridge between licensed crypto trading and emerging regulated digital asset products.
Regulation Drives Consolidation
The transaction comes as South Korea moves toward a more formal digital asset framework covering investor protection, exchange governance, stablecoins and tokenized finance. That regulatory shift is likely to favor exchanges with stronger capital bases, compliance infrastructure and institutional partners.
For Coinone, the investment improves its competitive position against larger domestic rivals by bringing in both international crypto infrastructure and domestic securities-market expertise. For OKX, it strengthens the company’s Asian regulatory strategy at a time when global exchanges are increasingly seeking compliant local entry points rather than relying only on offshore platforms.
The deal also reflects a broader industry trend. Large crypto firms are moving beyond pure exchange competition toward equity stakes, strategic partnerships and regulated infrastructure plays. In markets where licensing is difficult, minority ownership in local platforms can provide market access, regulatory credibility and long-term optionality.
The immediate market impact is unlikely to be visible in token prices because Coinone is privately held and the transaction is a strategic equity investment rather than a new tradable product. The longer-term significance lies in market structure. South Korea’s exchange sector is becoming more connected to global crypto capital and traditional finance balance sheets.
If the partnership succeeds, Coinone could gain stronger institutional capabilities while OKX deepens its access to Korean liquidity, regulation and customer behavior. The investment shows that in regulated crypto markets, ownership, compliance positioning and local partnerships are becoming as important as trading volume.
