Chainlink has launched a major expansion of its Data Streams product, bringing 24/5 U.S. equities and exchange-traded fund (ETF) market data onchain and opening access to the roughly $80 trillion U.S. stock market for decentralized finance applications.
The new offering, called Chainlink 24/5 U.S. Equities Streams, delivers fast, secure, and continuous market data across all major U.S. stocks and ETFs during regular trading hours, pre-market, post-market, and overnight sessions. For the first time, onchain markets can reliably access U.S. equity data beyond the standard 9:30 a.m. to 4:00 p.m. ET trading window, addressing a long-standing limitation that has kept equities significantly underrepresented in decentralized markets.
According to Chainlink, the structural mismatch between always-on blockchain markets and fragmented U.S. equity trading sessions has historically created pricing blind spots and increased risk for onchain trading platforms. Most existing data solutions only provided a single price point during regular market hours, forcing protocols to pause trading overnight or operate with stale reference prices. The 24/5 streams are designed to close that gap by transforming fragmented equity market data into continuous, cryptographically signed data streams.
The expanded data feeds go beyond simple price updates. In addition to mid-price data, the streams include bid and ask prices, bid and ask volumes, last traded prices, market-status flags, and staleness indicators. This broader market context allows developers to build more advanced trading logic, improve risk management, and enable safer execution for onchain products such as perpetual futures, lending markets, prediction markets, and synthetic equities.
Chainlink said the data is live across more than 40 blockchains and is built on its existing Data Streams infrastructure, which operates on a pull-based model designed for high-frequency trading. Unlike traditional price feeds that push periodic updates, Data Streams deliver sub-second updates only when trades occur, reducing gas costs while supporting continuous trading.
The new 24/5 U.S. equities coverage is already being adopted by several major derivatives and real-world asset platforms. Exchanges including BitMEX and Lighter, as well as ApeX, HelloTrade, Decibel, Monaco, Opinion Labs, and Orderly Network, are using the streams to power perpetual futures and other equity-linked products that can operate beyond standard market hours. Executives from BitMEX and Lighter said the data provides the integrity, low latency, and pricing context required to run professional-grade equity derivatives around the clock.
The data expansion is part of a broader effort by Chainlink to mirror the full lifecycle of traditional financial assets onchain. Alongside Data Streams for trading, the company is working with institutions such as Swift, Euroclear, and the Depository Trust & Clearing Corporation to automate corporate actions like dividends, stock splits, and mergers, helping ensure tokenized equities remain accurate without manual intervention.
Chainlink said the combination of continuous trading data and automated asset maintenance infrastructure is intended to align blockchain-based markets more closely with traditional financial systems. The announcement follows closely after the New York Stock Exchange revealed plans to introduce a blockchain-based, around-the-clock venue for tokenized stock and ETF trading later this year.
