OKX Ventures and Korea Investment & Securities Invest in South Korean Crypto Exchange Coinone
OKX Ventures, the investment arm of cryptocurrency exchange OKX, has announced a significant $53 million (KRW 80 billion) investment for a 19.6% stake in South Korean cryptocurrency exchange Coinone, according to a company statement. This move marks one of the largest recent investments by a global crypto firm into Korea’s digital asset sector. Korea Investment & Securities (KIS), one of South Korea’s largest brokerages, will also invest KRW 80 billion for an identical 19.6% stake, pending regulatory approval.
The Investment Structure and Ownership Changes
The combined KRW 160 billion ($106 million) deal will be structured through a mix of secondary share purchases from existing shareholders and subscriptions for newly issued shares. Following the investment, Coinone CEO Cha Myunghun is expected to remain the exchange’s largest shareholder with a 27.8% stake, retaining management control. Com2uS Holdings and its affiliates will hold 25% of the shares, while OKX Ventures and KIS will become joint third-largest shareholders.
This investment formalizes discussions first reported by Yonhap earlier this month, which indicated that OKX and KIS were considering acquiring roughly 20% stakes in Coinone. The deal underscores growing interest from global financial institutions in South Korea’s cryptocurrency market, which has seen increased regulatory scrutiny and institutional participation in recent years.
Implications for the South Korean Crypto Market
The investment highlights the expanding influence of international crypto firms in South Korea, a market that has faced both rapid growth and regulatory challenges. Coinone, one of the country’s earliest exchanges, has navigated a competitive landscape dominated by larger players like Bithumb and KuCoin. The influx of capital from OKX Ventures and KIS could bolster Coinone’s position, enabling it to enhance its technological infrastructure and expand its service offerings.

For OKX, this move aligns with its broader strategy to deepen its presence in Asia, where regulatory frameworks are evolving to accommodate blockchain innovation. Similarly, KIS’s participation signals a shift in traditional financial institutions toward cryptocurrency, reflecting a broader trend of institutional adoption.
Regulatory Approval and Future Outlook
The transaction remains subject to regulatory approval, a common hurdle in cross-border financial investments. South Korea has implemented stringent rules for cryptocurrency exchanges, including mandatory licensing and anti-money laundering (AML) protocols. Coinone’s compliance with these regulations will be critical to the success of the deal.
Analysts suggest that the investment could catalyze further consolidation in the South Korean crypto sector, as smaller exchanges seek partnerships with global players to remain competitive. However, the outcome will depend on how effectively Coinone integrates the new capital and navigates the regulatory environment.
As the crypto industry continues to mature, partnerships between international firms and local exchanges are likely to play a pivotal role in shaping the market’s future. The OKX and KIS investment in Coinone represents a significant step in this direction, signaling confidence in South Korea’s digital asset ecosystem.
