Polymarket Plans to Open New CLOB Market Maker Testing in November

The Vice President of the prediction market Polymarket, Josh, stated on platform X that the team is developing a central limit order book (CLOB) based on Rust, which is currently the root of most issues on the platform. The plan is to complete the full order lifecycle process in the testing environment by October, including trading, settlement, on-chain interactions, indexers, and engine notifications. In November, all production traffic will be mirrored to the new trading cluster, and results will be compared with the existing system, while testing permissions will be opened to market makers, locking in the migration switch plan and completing two full drills before the official switch. If progress goes smoothly, the new system will be officially released, and the migration is expected to require little or no changes for market makers and developers.
