The forecasting platform Polymarket is implementing new rules for submitting market outcome proposals, restricting this opportunity to selected and verified participants. This change is a result of the transition from the previous OOV2 system to the updated Managed Optimistic Oracle V2 (MOOV2) contract from UMA, which was approved in August 2025 through a vote on the UMA governance platform.

Main Changes and Their Purpose
The system update stipulates that market closure proposals can only be submitted by whitelisted addresses. The aim of this innovation is to reduce the number of unfounded or premature proposals that previously caused disputes and delays in decision processing, which sometimes lasted up to four days. At the same time, the ability to contest decisions remains available to all users of the platform.
Currently, the whitelist includes 37 addresses, among which are employees of Risk Labs and Polymarket, as well as users who have at least 20 verified proposals with an accuracy of over 95%. Before submitting a proposal, authors must discuss the idea with other participants in advance.
Discussion on Centralization and Future Prospects
The leadership of UMA and Polymarket argues that involving experienced authors in decision-making reduces the risk of errors, especially in markets with a low likelihood of conflicts – such as sports events, weather conditions, or cryptocurrency prices. However, critics believe that such restrictions may lead to the centralization of the platform. They suggest that instead of limiting the number of authors, clearer rules should be implemented for all participants.
“The change aims to reduce the number of disputes and improve the quality of verifications.”
Additionally, the implementation of MOOV2 is intended to protect the system from potential manipulations and attacks on governance mechanisms. The transition to the new model is currently in the testing phase: Polymarket has already launched the first requests on the Polygon mainnet, where users can earn real rewards for proposals.
It is worth noting that UMA and Polymarket are also collaborating with EigenLayer to create next-generation oracles for the forecasting market to enhance the reliability and functionality of the platform. Previously, it was reported that Polymarket is considering the possibility of generating profit from USDC reserves by launching its own stablecoin.
