Polymarket's New Matching Engine Nex Set to Launch in Mid-December, Delays Reduced by 412 Times

Polymarket's new matching engine, Nex, has been running in shadow mode on production traffic for a week. Internal tests show that the p99 order delay has decreased from 1.55 seconds to 3.76 milliseconds, the cancellation delay has dropped from 627.92 milliseconds to 3.20 milliseconds, and the WebSocket write delay (p99) has reduced from 44.5 to 88.1 milliseconds down to 0.099 milliseconds. Nex has a processing capacity of 100,000 instructions per second, peaking at 150,000, and the startup time has been shortened from 5 minutes to 15 seconds. Nex employs a deterministic design that eliminates race conditions present in the old system without making destructive changes to the request and response formats for market makers and developers. Nex will continue to operate in shadow mode for 4 weeks, and if everything goes smoothly, it is planned to launch in mid-December, with WebSocket improvements potentially being released earlier. Currently, Polymarket has opened a Nex sandbox for users to test.
