Summary
OKX, one of the world's largest cryptocurrency exchanges headquartered in San Jose, California, has confirmed a strategic investment partnership with Seoul-based Korea Investment & Securities to acquire meaningful stakes in Coinone, one of South Korea's largest digital asset trading venues. Under the agreement announced May 29, 2026, both OKX and Korea Investment & Securities will each secure a 20% ownership stake in Coinone, collectively acquiring a 40% position in the exchange. OKX's individual investment is valued at $53 million, with the combined transaction expected to exceed $300 million total.
Structurally, the investment will occur through newly issued shares in Coinone rather than through acquisition of existing equity, effectively representing a capital raise by the exchange. This approach preserves ownership stakes for Coinone's founder and current management while introducing significant new institutional capital and strategic partners. The involvement of Korea Investment & Securities, a traditional financial institution, alongside OKX underscores the convergence of cryptocurrency and conventional finance in Asia's digital asset markets.
OKX's move into South Korea parallels Binance's strategic expansion, which completed acquisition of Seoul-based Gopax in 2025 after initially securing a majority stake two years prior. This competitive dynamic reflects major crypto exchanges' emphasis on geographic diversification and access to regulated markets with substantial trading volumes. Coinone competes within a concentrated South Korean market that includes Upbit, Bithumb, and CoinW as primary competitors. Korea Investment & Securities' participation mirrors similar TradFi institutional positioning, evidenced by Mirae Asset's separate crypto exchange initiatives through its acquisition stake in Korbit, indicating traditional financial institutions' systematic entry into digital asset infrastructure ownership.
The transaction represents continued acceleration in crypto sector M&A activity as institutional capital flows toward established platforms with demonstrated user bases and regulatory compliance frameworks. For OKX, the capital injection positions Coinone for enhanced platform development, liquidity provision, and potential expansion of service offerings within South Korea's regulated crypto trading environment. The deal structure and valuation reflect broader institutional investor confidence in Asian crypto markets despite global regulatory scrutiny.
