OKX Coinone Stake Talks Signal Korea Exchange Shake-Up

OKX Coinone stake talks could give one of the world’s largest crypto exchanges a regulated route into South Korea. The reported structure would see OKX and Korea Investment & Securities each acquire about 20% of Coinone, creating a 40% outside-investor block before new ownership rules reshape the local exchange market.

OKX Coinone stake talks center on parallel 20% investments OKX is discussing a roughly 20% stake in South Korean exchange Coinone, while Korea Investment & Securities is in separate talks for a similar stake, according to Blockhead’s summary of Yonhap’s May 15 report . If both discussions close, the two buyers would together hold about 40% of Coinone. The deal has not been finalized. Blockhead reported that Coinone confirmed it is discussing partnerships with multiple firms, including possible strategic equity investments, but said no decision has been made. That matters because the transaction is still at the negotiation stage, not a signed acquisition. The reported structure also matters. Bitcoin.com said the stake purchase could happen through newly issued shares rather than a secondary sale from existing holders, meaning fresh capital would enter Coinone while current management control may not change immediately. The strategic angle is clear: OKX gets a Korean foothold, Korea Investment gets digital-asset exposure, and Coinone gets capital before South Korea’s ownership rules become more restrictive.

Korea’s exchange market is moving toward consolidation South Korea’s crypto market is dominated by a small number of won-linked exchanges, but the ownership base is now changing fast. The Coinone talks arrived the same week that Reuters reported Hana Bank would acquire a 6.55% stake in Dunamu, the operator of Upbit, for 1 trillion won, or about $700 million. Reuters said Upbit handles more than 80% of South Korea’s virtual-asset trading volume. That Dunamu deal gives the Coinone talks more weight. This is not a one-off foreign exchange exploring Korea. It is a broader reallocation of crypto-exchange ownership toward banks, brokerages and strategic investors. Mirae Asset Consulting has also been tied to a major Korbit stake purchase, according to Blockhead’s report. Cryptic Daily’s Crypto Newswire coverage has tracked the same pattern globally: exchange ownership is moving closer to regulated finance as crypto trading becomes too large for loose shareholder structures. Korea is now showing a local version of that trend, with domestic financial firms seeking exchange exposure while global players look for compliant entry points.

Ownership caps are the real deadline behind the talks The reported Coinone deal is not only about growth. It is also about regulation. South Korea has been considering a 20% cap on major shareholders in crypto exchanges under its Digital Asset Basic Act process. Korea JoongAng Daily reported that the government and ruling Democratic Party were weighing a 20% cap that could force ownership changes at major local exchanges. That cap would matter directly for Coinone. Blockhead reported that The One Group holds 34.30% of Coinone, Com2uS Holdings owns 21.95%, CEO Cha Myung-hoon holds 19.14%, and Com2uS Plus holds 16.47%. Cha founded Coinone and is also the largest shareholder of The One Group. Those numbers show why a restructuring may happen even if the OKX talks change or stall. A parallel 20% stake for OKX and Korea Investment would fit the proposed cap more cleanly than the current ownership concentration. It would also make Coinone’s investor base look more like a financial-market platform than a founder-controlled crypto venue.

OKX gets a possible Korea route after app-store pressure For OKX, the talks are a market-access story. South Korea is one of Asia’s most active crypto markets, but foreign exchanges face registration, app-store and compliance barriers. Blockhead reported that OKX was removed from South Korean app stores in January 2026 alongside Binance and Bybit for failing to register with the country’s Financial Intelligence Unit. That context makes a Coinone stake strategically valuable. A licensed local exchange gives OKX a path that direct offshore access could not provide. It would not automatically let OKX operate every global product in Korea, but it could create a compliant partnership route for liquidity, technology, institutional services or future product expansion if regulators approve the deal. OKX’s own market profile shows why the company would want that route. CoinMarketCap’s OKX exchange page describes OKX as a global exchange and Web3 services firm with operations tied to Hong Kong, Singapore, the UAE, Silicon Valley and the Bahamas. The exchange already has international

scale. Korea would add a difficult, high-value market where local licensing matters more than brand reach.

Coinone could gain capital but faces approval risk Coinone would gain more than money if the transaction closes. OKX could bring international liquidity relationships, product experience and exchange technology. Korea Investment & Securities could bring domestic brokerage credibility and local institutional ties. That combination could help Coinone compete in a market where Upbit dominates and smaller venues need stronger financial backers. The approval risk is just as real. A foreign-linked stake in a Korean exchange will attract regulatory review, especially after South Korea tightened virtual-asset oversight through the Virtual Asset User Protection Act and continued working on second-phase legislation. Reuters reported in February that South Korea’s Financial Supervisory Service called for tougher crypto rules after a Bithumb system incident raised concerns about exchange controls.

That warning is relevant to Coinone. Regulators will not assess only the cap table. They will review AML controls, beneficial ownership, operational resilience, market-abuse controls and whether a global exchange partner increases or reduces risk. For OKX, the deal could open a market. For Coinone, it could also invite a deeper supervisory review.

What to watch before the Coinone deal closes The next signal is whether Coinone, OKX or Korea Investment confirms binding terms. At this stage, the deal remains a reported negotiation. The structure matters: new-share issuance would strengthen Coinone’s balance sheet, while secondary sales would mainly change ownership among existing holders. The second signal is regulatory treatment of the 20% cap. If lawmakers move forward with the ownership limit and give exchanges a transition period, Coinone’s current shareholder base may need restructuring even without OKX. If exceptions up to a higher threshold are allowed by enforcement decree, the final ownership map could look different.

The third signal is whether South Korea’s exchange M&A wave keeps accelerating. Hana’s Dunamu investment, Mirae’s Korbit push and the OKX-Coinone talks all point in the same direction: banks, brokerages and global trading firms are moving before the new rulebook is locked. That is why the Coinone talks matter for readers following Web3 Builder as well as market structure. Exchange ownership decides who controls fiat rails, liquidity, custody, listing access and future tokenized-finance products. The next concrete milestone is formal confirmation of the stake structure and any regulatory filing tied to Coinone’s capital raise. If OKX secures a compliant minority position, Korea becomes a test case for how global exchanges enter tightly regulated local markets without buying full control.
