TREE NEWS update: Polymarket has opened sandbox testing for Nex, its new Rust-rewritten trading system, DeFi engineering vice president Josh announced on X. Nex has mirrored live production orders in shadow mode for the past week to validate latency, load stability and matching accuracy, but is not yet live. Internal tests show order latency P99 falling to 3.76 milliseconds from 1.55 seconds on the existing central limit order book, though the figure is not end-to-end latency. A four-week shadow test is planned, with launch expected in mid-December.

AI take
The headline number is the P99 latency drop, but Polymarket's own caveat that it is not end-to-end latency matters more than the gain itself — matching speed is only one leg of the path an order takes. For a prediction market pushing toward higher-frequency flow, the credibility test is whether the four-week shadow period surfaces divergence between Nex and the production book under real load, not lab conditions. Whether the mid-December target holds, and whether end-to-end figures are eventually published, are the open questions.
