Polymarket Integrates Chainlink Oracles to Resolve Price-Based Bets

Polymarket has formally partnered with Chainlink, integrating its Data Streams and Automation services to power prediction markets on the Polygon mainnet. The system enables near-instant settlement of Bitcoin and Ether markets, strengthening Chainlink’s dominance in the oracle space at 62%, according to DeFiLlama. Co-founder Sergey Nazarov called the collaboration a pivotal milestone, emphasizing tamper-proof computation and verifiable data. Polymarket, which recently acquired QCEX in a $112 million deal and secured CFTC clearance to re-enter the U.S. market, has processed more than $8 billion in wagers, including $6 billion in the first half of 2025. The platform now supports over 25 million positions and 1.2 million traders, and is nearing a $200 million funding round that would value it at $1 billion. The partnership extends beyond asset pricing into broader categories, reducing reliance on subjective voting systems. Chainlink has also expanded into traditional finance and government-linked data services, including collaborations with ICE, Japan’s SBI Group, and the U.S. Department of Commerce.
