Chainlink rolls out 24/5 on-chain data stream for U.S. stocks

Chainlink has launched a new on-chain data product that gives decentralized applications continuous access to U.S. stock and exchange-traded fund prices beyond standard market hours. 

The service, called 24/5 U.S. Equities Streams, delivers equity market data across regular, pre-market, after-hours, and overnight sessions.

The Jan. 20 launch expands Chainlink’s (LINK) Data Streams product and makes U.S. equities usable on-chain for five days a week, closing a long-standing gap between traditional market hours and always-on blockchain systems.

The service is live across more than 40 blockchains and covers all major U.S. stocks and exchange-traded funds.

Bridging market hours and on-chain trading

Until now, most on-chain equity products relied on limited price updates tied to regular U.S. trading hours. Outside of those windows, pricing often became stale, raising risks for derivatives, lending protocols, and synthetic asset platforms.

Chainlink’s new streams address that issue by providing sub-second updates throughout extended sessions. In addition to mid-price data, the feeds include bid and ask prices, volumes, last trade prices, and indicators that show whether the market is in a regular, pre-market, post-market, or overnight state.

Each update is cryptographically signed, allowing protocols to verify data integrity before using it.

This broader data set allows on-chain platforms to manage liquidations, funding rates, and margin requirements with more precision during off-hours, when price moves can still occur even though traditional exchanges are closed.

Early adoption across equity-based DeFi markets

Several trading platforms have already integrated the 24/5 equity streams to support continuous stock-based products. Lighter, currently the second-largest perpetual futures DEX by volume, is using the data to extend equity perps beyond standard trading sessions.

BitMEX has also adopted the streams to support its equity derivatives with real-time risk controls during extended hours. Other platforms using the service include ApeX, HelloTrade, Decibel, Monaco, Opinion Labs, and Orderly Network.

These integrations support use cases such as equity perpetuals, prediction markets, synthetic stocks, and lending products tied to U.S. equities.

The launch builds on Chainlink’s earlier rollout of real-time equity data in August 2025 and reflects growing demand for stock exposure inside decentralized markets.

With U.S. equities representing an asset class worth about $80 trillion, continuous and verifiable pricing has been a key missing piece for on-chain adoption.

Chainlink said the new data streams are available immediately, with documentation and integration tools provided for developers looking to add U.S. equity markets to their protocols.
