Much of Polymarket's core trading infrastructure was built years ago and is now being rearchitected to handle today's scale. ClobV2 with deposit wallet was the top non-negotiable priority because it's what prevents ghost fills the added latency you've seen since v2 mostly comes from new order and wallet validation infrastructure. With that protection in place, reducing latency to the fastest we ever had it is now our single biggest focus.
Over the next two weeks we have a series of releases dedicated to bringing latency down. Broadly, they target:
- Rewriting one of the slowest internal steps in the order flow.
- Smarter handling of activity bursts, aiming at reducing backed-up queues.
- Reworking the order book and its data flow. The single biggest latency reduction in the plan.
The first release in this series went live today. Expect the next latency releases toward the end of this week and next week.
