OKX had a genuinely busy week: a 50:50 joint venture with Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, and a roughly 20% stake in South Korean crypto exchange Coinone. For traders watching, this isn't just another partnership headline—it touches how crypto collateral, custody, and market access could work going forward.
OKX and ICE Form Joint Venture 'OKXICE'
ICE and OKX formed a 50:50 joint venture named OKXICE. On the surface, it reads like a compliance win: a global crypto exchange that faced serious US regulatory trouble is now backed by one of Wall Street's most established infrastructure firms. But the deeper story is about time, not just trust. Traditional finance runs on trading days, banking hours, and settlement windows; crypto runs continuously, with no closing bell, no weekend pause, and no holiday break.
ICE built its business on being the plumbing behind markets—matching, clearing, collateral, and risk control—and that plumbing was designed around scheduled downtime. OKXICE is essentially a live test of whether ICE's clearing and margin systems can be re-engineered for a market that never stops moving, using OKX's existing global user base, stablecoin rails, and trading infrastructure as the proving ground.
ICE previously tried building its own crypto platform, Bakkt, which struggled to gain traction because compliance alone failed to generate real trading demand—a lesson likely shaping this new approach of partnering with an exchange that already has liquidity and user habits in place.
OKX Ventures Buys Into South Korea's Coinone
Separately, OKX Ventures acquired approximately a 20% stake in South Korean crypto exchange Coinone. According to filings from May 2026, OKX Ventures and Korea Investment & Securities each hold about 19.6% ownership, making them the joint third-largest shareholders behind Coinone's founder and Com2uS Holdings.
This isn't just a passive investment; Coinone plans to integrate OKX's matching engine, custody systems, and wallet technology to strengthen trading infrastructure and institutional-grade services. Coinone's leadership highlighted that OKX's system handled over one million orders per second during last October's sharp Bitcoin decline without interruption as a key reason for the tech partnership.
The deal offers a foothold in Korea's tightly regulated market for OKX, while Coinone gains access to globally proven infrastructure and expertise. Both companies emphasized a shared engineering-led, compliance-focused philosophy between their CEOs. However, local Korean users and regulators have reportedly expressed caution about a foreign firm gaining meaningful ownership in a domestic exchange, which could shape how the partnership unfolds.
What Matters for Traders
Crypto markets never close, but most of the banking and clearing infrastructure behind traditional finance still runs on business-day hours. That mismatch is the real problem OKXICE is trying to solve—not simply 'listing more assets.' If ICE's clearing and risk-management systems can be adapted to a market that trades 24/7, it opens the door to using tokenized traditional assets—stocks, bonds, ETFs—as collateral inside crypto-native accounts. That's a bigger structural shift than another token listing.
On the Coinone side, the deal gives a mid-sized Korean exchange access to infrastructure that OKX says handled over one million orders per second during last October's market volatility without downtime. For Korean users, that's a direct pitch about platform stability during high-volatility events.
What to Watch Next
- Whether OKXICE publishes details on its clearing model for weekend or after-hours margin calls, since fiat settlement systems still run on banking hours;
- Regulatory reaction in Korea, where officials and users have already voiced caution about foreign capital taking stakes in local exchanges;
- Whether tokenized securities under OKXICE become usable as margin/collateral, not just tradable assets—this detail determines whether the venture is more than a compliance wrapper;
- Any follow-up from US regulators, given that OKX-related entities paid over $500 million in fines and forfeitures in 2025 over unlicensed money transfer activity.
