Chainlink has officially launched its new Data Streams product, bringing live, low-latency pricing data for major US equities and ETFs directly onto 37 blockchain networks. This marks a pivotal moment in blockchain innovation as developers gain the infrastructure needed to build tokenized trading platforms, perpetual futures, and synthetic financial products with unprecedented real-world data integration.
The announcement came via an official Chainlink blog post dated August 4. The new Data Streams feature offers real-time price feeds for widely traded assets, including SPY, QQQ, NVDA, AAPL, and MSFT, sourced from multiple primary and secondary providers and processed through Chainlink’s decentralized oracle networks (DONs).
Powering the Next Wave of Blockchain Finance
Each price data point is timestamped, ensuring time-sensitive integrity and enabling systems to recognize outdated feeds or suspend trading during traditional market closures. This detail is crucial for ensuring secure and compliant trading mechanisms on-chain.
Chainlink’s Chief Business Officer Johann Eid described the update as a major leap for decentralized finance (DeFi) and tokenized asset markets. “This is a significant leap forward for tokenized markets—closing a critical gap between traditional finance and blockchain infrastructure,” he said.
Use Cases: From Synthetic ETFs to Perpetual Contracts
Data Streams unlock a variety of new applications, including tokenized stock trading, lending and borrowing platforms, perpetual contracts, and synthetic ETFs. The infrastructure is especially relevant as the real-world asset (RWA) market is expected to surpass $30 trillion by 2030.
Prominent DeFi platforms, such as GMX and Kamino Finance, have already integrated Chainlink’s data streams. Kamino Finance co-founder Thomas Short praised the system for enhancing user experience while maintaining trust and transparency. “The launch of Data Streams for US equities and ETFs is a critical milestone toward a truly composable on-chain financial system that matches the scale and sophistication of traditional markets,” he stated.
Blockchain Meets Wall Street
By merging Wall Street-grade data with on-chain applications, Chainlink aims to push DeFi to new levels of maturity. The move demonstrates how blockchain infrastructure is now positioned to support complex financial products and real-world asset exposure in a decentralized environment.
With real-time access to equities pricing, developers and platforms can finally build DeFi solutions that reflect the nuances and speed of traditional markets while retaining on-chain transparency and accessibility.
