OKX launched Exchange OS, a platform for user-built crypto markets that OKX said can process up to 300,000 transactions per second. The platform lets users create spot, perpetuals, and outcomes markets with their own assets and governance. Exchange OS is in the first of three planned rollout phases, with broader public opening scheduled for the third quarter of 2026. The first market built on Exchange OS is a predictions-style market for the FIFA World Cup.
