Polymarket plans to deploy a new Rust-based trading engine in November 2026 to address ongoing performance and stability issues. This transition follows the scheduled October launch of an end-to-end order book system designed to manage increasing user traffic.
Why it matters
The platform requires improved scalability to manage growing trading volumes, which peaked at $800 million per week in September. Upgrading the infrastructure is critical to preventing outages and supporting the record-level activity seen in the prediction market sector.
Prediction market volume reached $63 billion in September, while Polymarket hit weekly volumes of $800 million. The company currently estimates a 6% probability that a POLY token release will occur before 2027.
The players
Polymarket
Polymarket is a prediction market platform that allows users to trade on the outcomes of real-world events.
The details
Engineers are currently developing a Central Limit Order Book system using the Rust programming language to replace existing infrastructure that has struggled with uptime. The migration process will include two full system rehearsals to ensure stability before the engine goes live.
Timeline
April 2026: Polymarket performed a V2 engine upgrade.
Early September 2026: A prediction trading API issue lasted 9 hours.
September 2026: Weekly trading volumes reached $800 million.
October 2026: End-to-end order book system release scheduled.
November 2026: New trading engine launch and final tests.
Macro View
This story highlights the infrastructure scaling required to accommodate the rapid expansion of decentralized prediction market trading volumes. The platform's infrastructure upgrades represent a necessary pivot to maintain stability as the wider prediction market industry sees multi-billion dollar monthly activity.
Users may experience transition periods during system rehearsals or the scheduled October and November releases. Improved stability is intended to reduce downtime, such as the 9-hour outage experienced in September, providing a more reliable trading environment.
The takeaway
Reliable infrastructure remains the primary barrier to mainstream adoption for high-volume prediction platforms. Users should prepare for potential platform volatility during the scheduled system upgrades this fall.
What happens next
The end-to-end order book system release is scheduled for October 2026, followed by final market maker tests in November 2026.
