Polymarket Launches Protocol V2 Ahead of November Upgrade

Modular Design Cuts Transaction Fees and Latency

Polymarket, the decentralized prediction‑market platform, began rolling out its upgraded smart‑contract system, dubbed Protocol V2, on October 6, 2026. The phased deployment precedes a full transition scheduled for November, aiming to support new markets while preserving existing positions for users worldwide.

The new protocol replaces the original contracts with a modular architecture that improves settlement speed, reduces gas costs, and adds built‑in safeguards against manipulation. Developers rewrote core functions to separate market creation, liquidity provision, and outcome resolution, allowing upgrades without halting active markets. Polymarket’s team says the change will also enable more complex question formats and integrate with emerging oracle networks, enhancing data reliability.

Under Protocol V2, each market operates as an independent contract linked to a central registry. This separation means that only the specific market’s code needs to be executed during trades, trimming gas usage by an estimated 30 percent. Early testers reported transaction confirmations in under five seconds, a notable improvement over the previous average of twelve seconds. „We wanted to make the user experience feel as seamless as a traditional betting platform,” said Polymarket co‑founder and CTO Maya Liu. „The modular approach lets us iterate quickly while keeping the system secure.”

How Will the November Transition Affect Existing Markets?

The upgrade also introduces a tiered fee structure that rewards high‑volume liquidity providers with lower fees, encouraging deeper order books. According to internal data, liquidity pools have already grown by 18 percent since the rollout began, suggesting that traders are responding positively to the cost savings.

Polymarket has assured users that all positions opened under the legacy protocol will be automatically migrated to the new contracts during the November cut‑over. The migration process involves a snapshot of each user’s balances, followed by a batch settlement that preserves outcome payouts. Users will receive on‑chain notifications prompting them to confirm the migration, but no action is required to retain their stakes.

The platform’s risk team has implemented additional oracle verification steps to guard against erroneous data feeds that could affect market outcomes. By integrating multiple data providers, Protocol V2 reduces reliance on any single source, lowering the risk of manipulation. „Our priority is to protect traders’ capital while expanding the range of questions we can host,” Liu added.

The November transition will also open the door for new market categories, including multi‑event bundles and conditional predictions that resolve only if a series of criteria are met. This flexibility is expected to attract institutional participants seeking more sophisticated hedging tools.
