OKX Ventures and Korea Investment & Securities are writing big checks. The two firms are each putting in $53 million to grab a combined 19.6% stake in Coinone, one of South Korea’s major crypto exchanges, bringing the total deal to $106 million.
That’s not a small bet. South Korea’s crypto market is one of the most active in Asia — retail trading volumes there have, at times, rivaled those of much larger markets — but it’s also one of the most tightly regulated. Getting a foothold inside a licensed, established exchange like Coinone is basically the fastest way for outside players to get serious exposure to that market without building from scratch. OKX Ventures, the investment arm of the OKX exchange group, and KIS, a well-known South Korean brokerage and investment bank, are splitting the cost evenly. Fifty-three million each. Clean and symmetrical.
The deal is still waiting on regulatory approval from South Korean authorities.
Why Coinone, Why Now
Coinone isn’t the biggest exchange in South Korea — Upbit and Bithumb tend to dominate those headlines — but it’s a significant, established player with a real user base and a track record of surviving the country’s regulatory waves. That matters a lot when you’re a foreign entity like OKX Ventures trying to plant a flag in the Korean market. Buying into a compliant, licensed exchange is faster and probably safer than trying to launch a new platform and navigate the Financial Services Commission’s approval process from zero.
KIS’s involvement is the part worth watching closely. Traditional South Korean financial institutions have been cautious about crypto. Very cautious. The country’s regulators spent years pushing back hard on digital assets, and most big brokerages kept their distance. So KIS stepping in for a $53 million crypto exchange stake isn’t nothing. It’s probably one of the more concrete signals yet that mainstream Korean finance is shifting its posture toward digital assets — not just in theory, but with real capital on the table.
It’s also worth noting the structure here. Neither firm is taking a controlling stake. At 19.6% combined, they’re minority investors. That means Coinone’s existing ownership stays in charge operationally, which is likely by design. Regulators in South Korea tend to scrutinize ownership changes at licensed exchanges pretty carefully, and a minority position is a much cleaner path to approval than a majority buyout.
Traditional Finance Meets Crypto, Korean Style
The broader trend here is real and it’s accelerating. Across Asia, traditional financial firms have been circling crypto exchanges with increasing seriousness. The logic isn’t complicated — digital asset trading volumes are enormous, fee revenue is attractive, and younger retail investors in markets like South Korea, Japan, and Southeast Asia are deeply engaged with crypto. Banks and brokerages that ignore that shift risk losing relevance with a whole generation of clients.
But South Korea is a specific case. The regulatory environment there is genuinely strict. The country passed real-name verification requirements years ago, forcing exchanges to partner with banks for user accounts. It’s pushed out a lot of smaller, sketchier operators. What’s left is a relatively small number of exchanges that have proven they can work within the system. Coinone is one of them.
That compliance history is probably a big part of why OKX Ventures and KIS picked Coinone specifically. You’re not just buying market share — you’re buying a regulatory track record. That’s worth something, maybe a lot of something, when you’re a firm that needs to keep its own regulators happy back home.
No timeline has been given for when the approval process might wrap up. No further comments from either firm on potential hurdles. Unclear whether there are conditions attached to the regulatory review or how long South Korean authorities typically take on deals like this. The source didn’t specify, and neither party has said publicly.
What $106M Buys Coinone
From Coinone’s side, the math is pretty straightforward. Fresh capital from two credible institutional backers — one a global crypto group, one a domestic Korean financial name — is a meaningful upgrade in both resources and legitimacy. The exchange can potentially push into new product lines, improve its tech stack, or just compete more aggressively on liquidity and user experience against Upbit and Bithumb.
And the KIS angle specifically could open doors. A domestic brokerage with deep relationships across Korean institutional finance is a different kind of partner than a pure crypto firm. It’s the kind of connection that could eventually help Coinone bridge retail crypto trading with more traditional investment products, if and when Korean regulations allow for it.
OKX Ventures, for its part, gets Korean market exposure without the headache of a full acquisition or a greenfield launch. Minority stake, board influence probably, and a front-row seat to one of Asia’s most interesting crypto markets.
The deal still needs the green light from Seoul. Until that comes through, it’s a signed agreement, not a closed one.
