Chainlink has launched a data service that brings prices for United States stocks and exchange-traded funds onto public blockchains throughout the trading week, aiming to close the gap between equity markets and decentralized finance.
The service, named 24/5 U.S. Equities Streams, delivers equity data across regular, pre-market, post-market, and overnight sessions, on-chain, and targets the 80 trillion dollar U.S. stock market, which has been difficult to mirror inside crypto markets.
Closing the Gap Between Market Hours and On-Chain Activity
Chainlink announced the new service on Jan. 20, saying it is intended to address the structural mismatch between crypto and U.S. equity trading hours and market structure.
Decentralized finance platforms operate without pause, while United States equity markets follow fixed daily sessions and fragmented venues, with many on-chain products that reference equities relying on a single reference price from the main session between 9:30 am and 4:00 pm Eastern Time, Chainlink said.
According to the company, that structure leaves long periods in which protocols either restrict activity or run with stale information, raising the risk of mispricing, sudden liquidations, and unreliable collateral values. The new streams seek to close that gap by turning fragmented U.S. equity sessions into a continuous 24/5 data feed, publishing updated prices across regular, pre-market, post-market, and overnight trading so that on-chain markets have fresher reference data beyond standard hours, Chainlink stated.
Deeper Market Signals for Pricing and Margin
The new service offers more than a single mid-price and extends to bid and ask prices, bid and ask volumes, last traded price, indicators showing whether a market is in regular, extended, or overnight trading, and measures of data freshness.
Furthermore, the service runs on Chainlink Data Streams infrastructure, which already underpins other oracle products across more than 40 blockchains, with data signed and delivered so they can be used during volatile trading in leveraged products and tokens that reference real-world assets.
Chainlink says this data standard has secured about 27 trillion dollars in transaction value, delivered roughly 19 billion verified messages on-chain, and supports close to 70% of oracle-related decentralized finance.
Growing Interest From Market Infrastructure Firms
Derivatives platforms, including Lighter and BitMEX, along with ApeX, HelloTrade, Decibel, Monaco, Opinion Labs, and Orderly Network, are already using the new feeds in equity-related markets, according to Chainlink. The company also said it plans to extend real-world asset coverage to additional asset classes and regions and to move toward around-the-clock equity data over time.
