Polymarket Partners with Chainlink to Enhance Accuracy of Prediction Market Resolutions

Partnership Delivers Tamper-Resistant, Verifiable Outcomes to Millions of Polymarket Users Through Chainlink's Onchain Data

SAN FRANCISCO, Sept. 12, 2025 /PRNewswire/ -- Chainlink, the industry-standard oracle platform for onchain finance, and Polymarket, the world's largest prediction market, today announced a partnership to integrate the Chainlink data standard into Polymarket's resolution process. The partnership will initially focus on enhancing the accuracy and speed of asset pricing resolutions, with plans to expand into additional markets. 

Polymarket's integration of Chainlink is now live on Polygon mainnet, enabling the creation of secure, real-time prediction markets around asset pricing, including hundreds of live crypto trading pairs. Beyond deterministic markets, which have a clear definitive resolution, Polymarket and Chainlink are also exploring methodologies to expand the use of Chainlink to settle prediction markets involving more subjective questions, thereby reducing reliance on social voting mechanisms and further minimizing resolution risk.

By leveraging decentralized oracle networks, Chainlink provides deterministic data inputs to resolve Polymarket outcomes. The integration combines Chainlink Data Streams, which provide low-latency, timestamped, and verifiable oracle reports, with Chainlink Automation, enabling timely, automated onchain settlement of markets. The infrastructure allows for near-instantaneous resolution of asset pricing markets, such as Bitcoin price predictions, according to a predetermined date and time.

"Polymarket's decision to integrate Chainlink's proven oracle infrastructure is a pivotal milestone that greatly enhances how prediction markets are created and settled. When market outcomes are resolved by high-quality data and tamper-proof computation from oracle networks, prediction markets evolve into reliable, real-time signals the world can trust. Polymarket's partnership with Chainlink is a decisive step toward a world powered by cryptographic truth." — Sergey Nazarov, Co-Founder of Chainlink.

With nearly $100 billion in DeFi total value secured and having enabled tens of trillions in transaction value, Chainlink's data infrastructure has proven its security and reliability by sourcing reliable data that already safeguards hundreds of leading DeFi protocols. Powered by a decentralized network of independent, enterprise-grade node operators with unmatched reliability and accuracy, Chainlink's architecture eliminates single points of failure, ensuring applications function exactly as intended.

Since its launch in 2020, Polymarket has experienced tremendous growth as it has emerged as a vital source of trusted real-time information around the world. Most recently, Polymarket completed the $112 million acquisition of QCEX, a CFTC-licensed exchange and clearinghouse, paving the way for its re-entry into the U.S. market. The company also announced an official partnership with 𝕏 to launch an integrated product that delivers data-driven insights and personalized market recommendations to users.
