Chainlink has deepened its grip on the oracle market after announcing a major partnership with Polymarket, the world’s largest on-chain prediction market, to enhance market resolution accuracy and speed.
The deal cements Chainlink’s dominance at 62% of the oracle sector, according to DeFiLlama, indicating its growing role as key infrastructure for decentralized finance.

According to the announcement, Polymarket has integrated Chainlink’s Data Streams and Automation services into its resolution process, with the system now live on the Polygon mainnet.
The collaboration allows near-instant settlement of prediction markets, beginning with asset-pricing markets on assets such as Bitcoin and Ether.
Chainlink’s decentralized networks deliver low-latency, timestamped data while eliminating single points of failure, ensuring that resolutions are both secure and verifiable.
Polymarket, which has grown rapidly since launching in 2020, has positioned itself as a global hub for real-time information.
The platform recently acquired QCEX, a CFTC-licensed exchange and clearinghouse, in a $112 million deal to prepare for a return to the U.S. market. It has also partnered with X to integrate personalized market recommendations into the social platform.
The latest move with Chainlink further strengthens Polymarket’s infrastructure, reducing reliance on subjective voting systems and minimizing resolution risks in more complex market types.
Chainlink co-founder Sergey Nazarov described the deal as a “pivotal milestone,” adding that resolving markets with tamper-proof computation and high-quality data transforms prediction markets into reliable signs “the world can trust.”
The integration marks the beginning of a broader collaboration between the two companies, with plans to expand beyond asset-pricing into more subjective prediction categories.
The agreement comes at a time when Chainlink has accelerated its expansion into traditional finance and government-linked data services.
On August 11, the firm partnered with Intercontinental Exchange (ICE) to provide on-chain foreign exchange and precious metals rates through its Data Streams, using ICE’s Consolidated Feed sourced from over 300 marketplaces.
Two weeks later, Japanese financial giant SBI Group revealed a collaboration with Chainlink to develop crypto tools for banks and institutions in Japan and the Asia-Pacific region, with an initial focus on tokenized bonds and stablecoin reserves.
