Acquisition Overview
Published 7/6/2026, 9:10:22 AM
The acquisition of a stake in Coinone by OKX Ventures, announced on May 29, 2026, has the potential to significantly modernize South Korea’s crypto trading infrastructure by integrating global liquidity and institutional-grade technology. However, the "boost" is currently tempered by severe regulatory hurdles and a pending approval process from the Financial Services Commission (FSC).
Acquisition Overview
OKX Ventures, in partnership with Korea Investment & Securities (KIS), has moved to acquire a 19.6% stake in Coinone for 80 billion won (~$53 million). This specific stake size is strategically positioned just below the FSC’s 20% ownership cap for major shareholders in domestic exchanges.

| Investment Amount | 80 billion won (~$53 million) |

| Market Share | ~6.6% to 13% (estimated) |
Potential Infrastructure Enhancements
The partnership aims to address three critical areas of South Korea's digital asset ecosystem:
- Liquidity and Market Depth: By connecting Coinone to OKX’s global liquidity networks, the exchange aims to deepen its order books. This is intended to reduce slippage, making the platform more attractive to institutional and high-volume retail traders who currently favor Upbit or Bithumb.
- Institutional Product Suites: Through the involvement of Korea Investment & Securities, the deal focuses on developing Security Token Offerings (STOs) and stablecoin initiatives. This bridges traditional financial (TradFi) infrastructure with on-chain assets.
- Compliance and AML Technology: OKX intends to transfer its international expertise in Anti-Money Laundering (AML) and user protection frameworks to Coinone. This is a critical infrastructure "upgrade" given Coinone's recent regulatory struggles.
Competitive Landscape
Coinone remains a distant third in a market dominated by a "duopoly." Competitors are also aggressively upgrading their technical infrastructure:
- Upbit (Market Leader): Recently launched GIWA, an Ethereum-based Layer 2 built on Optimism’s technology, designed for institutional settlement with reported 1-second block times [Note: 1-second block time not independently confirmed].
- Hana Financial Group: Invested approximately $668M into Dunamu (Upbit's parent) in 2026 to solidify its position in the market.
- Mirae Asset: Reportedly acquired Korbit to compete in the institutional segment.
Critical Risks and Regulatory Barriers
The acquisition's ability to boost infrastructure is currently stalled by regulatory sanctions and pending approvals:
- KYC Deficiencies: In April 2026, the Financial Intelligence Unit (FIU) fined Coinone $3.5 million for approximately 70,000 deficient KYC cases.
- Suspension Risk: While the Seoul Administrative Court paused a 3-month business suspension in May 2026, the underlying compliance risks remain.
- FSC Approval: The change in major shareholding requires explicit approval from the FSC. Given the recent AML failures, regulators may impose strict conditions or delays on the OKX integration.
Conclusion
OKX’s entry could provide the capital and technical sophistication necessary to break the Upbit/Bithumb dominance and introduce advanced institutional tools like STOs to the Korean market. However, the immediate impact is restricted by Coinone's ongoing compliance remediation. The infrastructure "boost" will only materialize if OKX successfully navigates the FSC approval process and resolves Coinone's systemic AML deficiencies.
