Polymarket, one of the largest on-chain prediction platforms, has announced a major integration with Chainlink’s oracle infrastructure to enhance the accuracy and reliability of market resolutions.
According to the press release, the collaboration combines Chainlink Data Streams, which provide low-latency, timestamped price feeds, with Chainlink Automation, enabling automatic settlement of prediction markets at scheduled times.
The upgrade is already live on Polygon mainnet for price-driven markets like crypto trading pairs, aiming to deliver faster outcomes while making manipulation significantly harder.
Prediction markets have historically faced issues with delayed or disputed resolutions, leading to payout controversies and user distrust. Polymarket previously switched from Optimistic Oracle V2 to UMA’s Managed Optimistic Oracle V2, introducing a whitelisted resolution system to improve fairness.
The new integration with Chainlink further addresses these challenges by supplying deterministic, auditable data instead of relying solely on social voting.
This move follows past controversies, including oracle governance attacks in third-party systems and a high-profile market tied to Ukrainian President Volodymyr Zelenskyy’s attire, which raised concerns about manipulation and subjectivity in outcomes.
Chainlink’s Vision: Turning Predictions Into Reliable Signals
Chainlink, already a cornerstone of DeFi infrastructure, secures large amounts of on-chain financial activity with its decentralized oracle networks. The partnership with Polymarket is positioned as a step toward transforming prediction markets into “trustworthy, real-time indicators.”
“When markets resolve based on high-quality data and tamper-proof computation, they become reliable signals the world can trust,” said Sergey Nazarov, Chainlink’s co-founder.
Expanding Polymarket’s Reach in 2024
Founded in 2020, Polymarket allows users to trade on real-world events and has rapidly grown into one of the most recognized prediction platforms in crypto. Both retail investors and institutions now use Polymarket’s odds as information signals for decision-making.
Earlier this year, Polymarket also revealed plans to acquire QCEX, a CFTC-licensed exchange and clearinghouse, setting the stage for an expansion into the U.S. market.
