The NYSE parent company, ICE, has formed a new partnership with OKX after completing an investment that values the crypto exchange at $25 billion. ICE will also hold a seat on the OKX board as the firms plan new market products. The agreement follows a long set of talks between senior leaders from both sides. Haider Rafique from OKX met Jeffrey Sprecher during an early meeting that later grew into a full set of reviews and planning sessions.
