Chainlink Launches 24/5 Data Streams for U.S. Stocks and ETFs

Key Highlights

Chainlink launched 24/5 U.S. Equities Streams to provide continuous stock and ETF data beyond normal U.S. market hours.
Exchanges like BitMEX and Lighter are already using the service for perpetual futures and other on-chain financial products.
The streams include full market data like prices, bid/ask, trade volumes, and market status, aimed to help developers reduce risk and improve trading accuracy.

Chainlink, the oracle platform, launched 24/5 U.S. Equities Streams today, a new service providing market data for U.S. stocks and ETFs across all major trading sessions.

The service allows blockchain developers and institutions to access real-time equity data beyond standard market hours, including regular, post-market, and overnight trading.

According to the announcement, the rollout is expected to fix an issue in the blockchain market where traditional stock markets only allow trading for a few hours a day. By using this system, on-chain platforms can now trade equities safely, keep prices accurate, and create new financial products without stopping during off-hours. Chainlink built this service on its Data Standard, which has handled over $27 trillion in transactions.

What the streams offer

The streams include more than just price updates. They offer bid and ask prices, trade volumes, market status flags, mid-prices, staleness indicators, and last traded prices, giving developers the information needed to build better pricing models and manage risks.

“A core reason for this is structural: blockchain-enabled trading operates continuously 24/7/365, while U.S. equity markets trade across fragmented sessions during dedicated market hours. Furthermore, most onchain data solutions only provide a single price point for equities during standard trading hours (weekdays 9:30 AM – 4:00 PM ET), creating a gap where onchain markets are unable to reliably replicate market conditions all 24 hours of the day,” the firm said.

The system operates on a “pull” model, sending sub-second updates only when trades occur, which helps reduce on-chain costs and improves efficiency for high-frequency trading.

Industry support

Multiple exchanges and platforms are already using the streams. For instance, BitMEX and Lighter rely on the data to run perpetual futures contracts that never expire, while ApeX, HelloTrade, Decibel, Monaco, Opinion Labs, and Orderly Network have integrated it for other RWA applications.

Lighter CEO Vladimir Novakovski commented on the service, stating, “This enables us to extend our fair, low-latency perp execution beyond regular market hours without compromising data integrity.” Meanwhile, BitMEX CEO Stephan Lutz said, “For derivatives markets, security and data integrity matter more than anything. Chainlink’s 24/5 U.S. Equities Streams are a critical component of our professional-grade 24/7 equity derivatives infrastructure.”

Why this matters

Until now, blockchain platforms could not trade U.S. stocks safely outside normal hours, which left decentralized exchanges unable to maintain accurate prices during off-hours. But now, with continuous data, Chainlink allows tokenized equities to function properly around the clock.

The firm is also working with Swift, Euroclear, and DTCC to automate corporate actions like dividends, stock splits, and mergers, ensuring tokenized assets stay accurate.

Live across more than 40 blockchains, developers can now integrate the streams to support equity perps, lending platforms, synthetic assets, prediction markets, and other on-chain applications.
