Summary
Korea Investment & Securities and OKX Ventures have completed agreements to acquire equal 20% stakes in Coinone, positioning traditional finance and global crypto infrastructure within one of Asia's most established digital asset exchanges. The combined $106 million investment represents a significant validation of South Korea's cryptocurrency market maturity and regulatory standing. Each investor will hold newly issued shares alongside existing shares purchased from Coinone CEO Cha Myung-hoon and Com2uS Holdings.

The post-transaction shareholding structure reflects a balanced ownership model. Cha retains controlling shareholder status at 30.36%, Com2uS Holdings maintains a substantial 24.54% position, and Korea Investment & Securities and OKX Ventures each hold 20%, making them joint third-largest shareholders. This structure preserves existing leadership while introducing institutional capital and operational expertise from both a major Korean financial services firm and the investment arm of a global cryptocurrency exchange.

Korea Investment & Securities CEO Kim Sung-hwan framed the transaction as "the first step in expanding beyond traditional finance into blockchain-based digital financial services." The Korean broker-dealer plans to leverage Coinone's platform and regulatory relationships to develop tokenized securities, stablecoins, and blockchain-based financial infrastructure as South Korea establishes a comprehensive digital asset regulatory framework. Netero Dai of OKX Ventures emphasized that South Korea represents "one of the world's most mature digital asset markets" with a "highly regarded" regulatory environment, indicating OKX's confidence in the country's institutional infrastructure and long-term market potential.

Coinone CEO Cha Myung-hoon stated that the selected investors were chosen for their ability to create "strategic synergies across finance, technology and digital assets." The partnership is expected to strengthen Coinone's investor protection, security, and risk management capabilities while providing access to international market expertise through OKX's global network. All parties have committed to regulatory cooperation on shareholder change procedures, underscoring the compliance-focused nature of the transaction. A joint media briefing scheduled for June will detail the partnership structure and outline areas of future collaboration among the four stakeholders.
