TL;DR: Polymarket has begun testing Protocol V2, a major rebuild of the smart contracts behind its prediction markets. The architecture consolidates markets around a unified exchange system and pUSD collateral, with canary testing expected to continue through October 30 ahead of a tentative November 2 transition for new markets.
Polymarket is replacing much of the infrastructure underneath the product that made it one of crypto’s best-known prediction markets.
Protocol V2 has entered live testing, introducing a new smart-contract architecture designed to simplify how markets, positions, collateral and settlement interact.
The changes are deeper than a user-interface refresh.
Polymarket’s existing infrastructure grew over time around a collection of contracts and extensions.
V2 moves toward a more unified structure capable of supporting different market types through a common system.
One of the most visible changes is collateral.
The new architecture standardizes around pUSD, giving new markets a common collateral asset rather than relying on the older arrangement.
Positions are also being consolidated through a shared token framework, while routing and oracle components are being reorganized to make new market types easier to support.
Polymarket is not moving everything at once.
A limited set of canary markets is being used to test the V2 contracts in live conditions through October.
The current schedule calls for that testing phase to run until October 30, with November 2 targeted as the point at which new markets begin moving fully to the updated system.
Existing markets do not simply disappear.
Legacy positions can continue to settle under the infrastructure on which they were created.
That phased approach reduces the risk of forcing open markets through a contract migration while funds and positions remain active.
The overhaul arrives as prediction markets continue to expand beyond a niche crypto product.
Platforms such as Polymarket now attract substantial attention around elections, macroeconomic events, technology, sports and breaking news.
As volumes and market variety increase, infrastructure built for a smaller product can eventually become a constraint.
Protocol V2 appears designed to solve that before it becomes a larger problem.
The upgrade also gives Polymarket more flexibility in how it creates markets and resolves outcomes.
That could become important as the platform expands into more complicated events that cannot always be represented cleanly by a single yes-or-no contract.
For users, the immediate change may look modest.
Underneath the interface, however, Polymarket is replacing much of the system responsible for determining what a position is, what backs it and how it settles.
For a prediction market, there are few pieces of infrastructure more important than those.
