South Korean brokerage Korea Investment & Securities is reportedly reviewing a potential investment in crypto exchange Coinone. While discussions are ongoing, both parties have indicated that no final agreement has been reached.
The reported talks come as South Korea considers regulatory changes that could significantly reshape ownership structures in the domestic crypto exchange sector. A proposed rule would cap major shareholders’ stakes in exchanges at 20%, potentially forcing existing owners to reduce their holdings. Coinone Chairman Cha Myung-hoon is said to control more than 50% of the company, meaning a partial stake sale could become necessary if the regulation is enacted.
KIS has reportedly begun engaging with regulators and policymakers as part of the broader evaluation process. With strong financial performance, including over $1.3 billion in net profit in 2025, the firm is seen as a credible candidate to acquire a meaningful stake in the exchange. Such a move would mark a deeper push by traditional financial institutions into the crypto sector.
The potential investment also reflects a broader trend among major South Korean firms seeking exposure to digital assets. Rival Mirae Asset Group has already taken steps in this direction, agreeing to acquire a controlling stake in crypto exchange Korbit earlier this year. These developments suggest increasing competition among established financial players to secure positions in the evolving crypto market.
Regulatory momentum is playing a central role in driving these shifts. The South Korean government, along with the Financial Services Commission, has been working on measures to enhance transparency and reduce concentration risks in the crypto industry. If the proposed ownership cap is implemented, exchanges would reportedly have up to three years to comply by restructuring their shareholder bases.
