Chainlink has unveiled a new product called Data Streams, designed to supply live pricing data for major US equities and exchange-traded funds (ETFs) directly onto blockchain networks. This service includes popular assets such as SPY, QQQ, NVDA, AAPL, and MSFT, providing low-latency, real-time data updates.
Currently operational across 37 blockchain networks, Data Streams enable novel applications including tokenized stock trading, perpetual futures, and synthetic ETFs. By aggregating real-time data from multiple primary and backup sources, Chainlink ensures continuous uptime. The data is processed through decentralized oracle networks (DONs) and delivered on-chain in a structured format, with each data point timestamped to distinguish fresh prices from outdated ones.
This timestamping allows automatic suspension of trading during market closures, ensuring trading activity aligns with official market hours. These features empower developers to create sophisticated financial instruments like perpetual contracts, lending and borrowing platforms, and synthetic ETFs. The need for such infrastructure grows as the real-world asset (RWA) market is projected to reach $30 trillion by 2030, highlighting the importance of secure and scalable tokenized equity markets.
Johann Eid, Chainlink’s Chief Business Officer, emphasized that Data Streams represent a pivotal advancement in bridging traditional finance with blockchain technology, describing it as “a significant leap forward for tokenized markets.” Leading decentralized finance (DeFi) protocols such as GMX and Kamino Finance have already integrated Data Streams into their platforms.
Thomas Short, co-founder of Kamino Finance, noted that the integration would improve user experience by providing a seamless interface while maintaining security and trust. He called the launch a “critical milestone toward a truly composable onchain financial system that matches the scale and sophistication of traditional markets.”
