Chainlink has significantly enhanced its presence in the oracle market through a pivotal partnership with Polymarket, the largest on-chain prediction market globally. This collaboration aims to improve the accuracy and speed of market resolutions, further solidifying Chainlink’s dominant market share, which now stands at 62% according to DeFiLlama.
The newly announced integration allows Polymarket to utilize Chainlink’s Data Streams and Automation services within its resolution process, which has already gone live on the Polygon mainnet. As a result, prediction markets can now be settled nearly instantaneously, starting with assets like Bitcoin and Ether. The integration employs Chainlink’s decentralized networks to provide low-latency, timestamped data while eliminating single points of failure—a crucial feature for ensuring the security and verifiability of resolutions.
Since its launch in 2020, Polymarket has rapidly evolved into a significant player in the realm of real-time information, recently acquiring QCEX, a CFTC-licensed exchange and clearinghouse, in a $112 million deal aimed at re-entering the U.S. market. In addition, Polymarket has partnered with X to deliver personalized market recommendations, engaging users with real-time widgets and AI summaries that help turn trending topics into crowd-sourced forecasts.
The collaboration with Chainlink further fortifies Polymarket’s operational infrastructure by reducing reliance on subjective voting methodologies and minimizing resolution risks associated with more intricate market dynamics. Sergey Nazarov, Chainlink’s co-founder, heralded the partnership as a transformative milestone, asserting that the use of tamper-proof computation and high-quality data will enhance the reliability of prediction markets.
As part of a broader strategy, Chainlink has accelerated its outreach into traditional finance and governmental data services. Notably, in August, it partnered with the Intercontinental Exchange (ICE) to relay on-chain foreign exchange and precious metals rates, leveraging ICE’s Consolidated Feed sourced from over 300 marketplaces. Additionally, Japanese financial giant SBI Group announced a collaboration with Chainlink to develop crypto tools aimed at banks and institutions across Japan and the Asia-Pacific region, initially focusing on tokenized bonds and stablecoin reserves. Furthermore, on August 28, the U.S. Department of Commerce began publishing official economic data on-chain via Chainlink, marking the first instance where government statistics are rendered verifiable on blockchain networks.
Chainlink has emerged as a crucial infrastructure for decentralized finance, with approximately $100 billion in total value locked in DeFi and trillions in transaction value supported by its oracles. This recent surge in partnerships highlights Chainlink’s growing importance within the broader financial ecosystem.
Polymarket, having recently cleared regulatory hurdles with the U.S. Department of Justice and the Commodity Futures Trading Commission, is poised for significant expansion. The closures of their investigations into the platform, which questioned its compliance with prior agreements to block U.S. users, signify a transformative moment for Polymarket as it regains the ability to operate within the U.S. market.
The CFTC granted a no-action letter that allows Polymarket to offer compliant prediction contracts through QCX LLC and QC Clearing LLC, the entities it acquired earlier this year. This regulatory clearance provides a pathway for offering prediction markets while ensuring compliance with swap reporting and recordkeeping mandates.
Polymarket stands as a giant in the realm of prediction markets, having processed over $8 billion in wagers, with $2.5 billion recorded during the 2024 U.S. election cycle. In the first half of 2025 alone, users placed approximately $6 billion in bets. Currently, Polymarket boasts more than 1.2 million traders and has accounted for over 25 million positions, amidst an overall prediction market volume of $1.1 billion.
Furthermore, the platform is on the brink of a $200 million funding round led by Founders Fund, which would value it at around $1 billion. Donald Trump Jr.’s 1789 Capital has also joined as an investor and advisory partner, showcasing increasing institutional and political interest in the expanding platform.
