Korea Investment and Securities (KIS), a domestic securities company, is simultaneously acquiring a separate roughly 20% stake in Coinone, according to reporting from The Block and CoinDesk. The two investments together would shift up to 40% of Coinone's ownership. Both buyers structured their purchases primarily as new share issuances, meaning the capital flows into Coinone as working funds rather than to existing shareholders. Neither OKX nor KIS will disrupt the exchange's current leadership team under CEO Cha Myunghun, who founded Coinone in 2014.

At $53 million for a 20% share, the deal implies a post-money valuation of roughly $265 million for Coinone. That figure is approximately 4.4 times the exchange's total book equity of about $59 million (81.91 billion Korean won) reported for 2025. An earlier report from Korean crypto outlet Bloomingbit placed the combined 40% block at 500 to 600 billion won, or roughly $363 to $435 million total, but those figures predate the confirmed terms and should be treated as preliminary until KIS discloses its own investment amount separately.

Why the VASP License Is the Real Prize

Coinone holds roughly 5% or less of South Korean domestic trading volume, trailing far behind Upbit (approximately 65 to 72 percent, based on Q4 2025 figures) and Bithumb (approximately 25 to 31 percent over the same period). On a given day, its spot market processes around $47.9 million in volume across 200-plus digital assets. By itself, that market share is modest. What Coinone actually offers OKX is its registration as a Virtual Asset Service Provider (VASP) under South Korea's Financial Intelligence Unit (FIU).

South Korea requires all crypto exchanges to hold FIU registration to offer Korean won fiat pairs and process local deposits and withdrawals. Unregistered foreign platforms cannot legally onboard Korean retail users through native fiat channels. OKX, along with Binance and Bybit, was removed from South Korea's Google Play Store on January 28, 2026, for operating without that registration, though web access remained available after the removal. The Coinone deal sidesteps an FIU application process that took Binance more than two years to complete after it acquired Gopax, a smaller Korean exchange, in early 2023. Binance's US legal proceedings settled in May 2025, and the FIU approved the Gopax deal five months later, in October 2025, illustrating that regulatory clearance does not follow automatically from legal resolution.

The Korean won now accounts for approximately 30% of global crypto trading volume, according to MEXC data for 2026. South Korea's exchanges processed roughly $277.9 billion in combined volume during Q4 2025 alone. For OKX, which already derives about 30% of its global centralized exchange volume from Asia-Pacific and was growing that region at approximately 20% year over year as of early 2026, locking in Korean retail access is a direct revenue priority.

Regulatory Complications Are Already in Play

Coinone's compliance record adds friction to any near-term integration. In April 2026, South Korea's FIU fined Coinone approximately $3.5 million (5.2 billion won) for failing to verify roughly 70,000 customer accounts, a violation of anti-money laundering rules. The regulator also imposed a partial business suspension: Coinone cannot register new users from April 29 through July 28, 2026. That suspension limits how quickly OKX can use Coinone as a growth vehicle.

The 2026 fine is not Coinone's first serious compliance episode. In 2023, a former Coinone listing director acknowledged accepting approximately 2 billion won (roughly $1.5 million) to list specific tokens on the exchange. Taken together with the AML failure, the two events form a pattern of compliance shortfalls that OKX will need to actively manage as it integrates the platform.

There is also a structural question tied to incoming legislation. The Digital Asset Basic Act, currently advancing through South Korea's National Assembly and not yet enacted, proposes a 20% cap on individual shareholders in crypto exchanges. The Financial Services Commission retains discretion to approve stakes up to 34%. OKX's 20% acquisition lands exactly at the proposed legal ceiling. The complication is that Coinone's existing shareholders already exceed that cap. The One Group holds 34.3% and Com2uS Holdings holds 21.95%. Compliance with the new law will require cap table restructuring from existing holders, not just the incoming investors. Smaller exchanges such as Coinone would receive a six-year grace period (structured as two three-year phases) beginning from the law's enactment date, once the legislation clears the Assembly.

A Market in Rapid Consolidation

The OKX deal did not arrive in isolation. On the same day, Hana Financial Group announced an approximately $727 million investment for a 6.55% stake in Dunamu, the parent company of Upbit. Mirae Asset is separately pursuing a position in Korbit, another licensed Korean exchange, though that transaction has not been confirmed as of publication. The pattern is consistent: established Korean financial institutions and global crypto firms are racing to lock in positions before the regulatory framework tightens further and before liquidity concentrates even more heavily around Upbit.

OKX's leadership has said publicly that the company will not pursue an IPO until it can deliver returns to existing investors, signaling the firm is in an expansion phase rather than a capital-raising one. The Coinone deal fits that posture. If the Binance and Gopax precedent holds, analysts expect at least one more top-10 global exchange to announce a similar minority stake in a licensed Korean platform within the next 12 to 18 months, with Bybit and Gate.io among the candidates most frequently named in that analysis.
