Chainlink has introduced Data Streams, a new service designed to bring real-time pricing for U.S. equities and exchange-traded funds directly onto blockchain networks. The launch targets the fast-growing tokenized real-world asset market and makes high-frequency market data available across 37 blockchains. Supported assets include SPY, CRCL, QQQ, NVDA, AAPL, and MSFT.
Built for tokenized financial products
According to Chainlink, the service includes features such as market hours enforcement and staleness detection, while sourcing data from premium providers. The goal is to give developers infrastructure that can support institutional-style reliability for onchain applications. With this setup, builders can create products such as tokenized stock trading, perpetual futures, and synthetic ETFs.
Johann Eid, chief business officer at Chainlink Labs, said the launch marks a major step forward for tokenized markets by helping close a long-standing gap between traditional finance and blockchain infrastructure. Chainlink is positioning Data Streams as a foundational layer for scaling secure, high-performance onchain financial markets tied to traditional assets.
Early adoption from GMX and Kamino
Two DeFi protocols, GMX and Kamino, are already adopting the new data streams. GMX said decentralized, institutional-grade pricing infrastructure is necessary if DeFi is to expand beyond crypto-native assets. Kamino co-founder Thomas Short highlighted the combination of performance and decentralization, arguing that it is especially important for building applications such as lending on Solana without weakening security.
RWA momentum and regulatory backdrop
The launch also comes as tokenized real-world assets continue to gain momentum. The report notes that the RWA market could reach $30 trillion by 2030. At the same time, new U.S. legislation, including the GENIUS Act, is being viewed as a sign of broader institutional readiness for blockchain-based market infrastructure. Chainlink argues that as data delivery improves, the conditions for bringing traditional capital markets onchain are becoming increasingly viable.
