Chainlink has launched 24/5 U.S. Equities Data Streams, giving DeFi protocols sub-second stock and ETF data across all trading sessions. The service extends Chainlink’s Data Streams product to cover pre-market, regular, and after-hours activity for major U.S. names.
What Chainlink’s 24/5 Equities Data Streams Deliver
The new feeds provide fast, encrypted market data for U.S. equities and ETFs, updated continuously five days a week. Coverage spans virtually all major U.S. stocks and index trackers, providing access to an equity market worth about $ 80 trillion.
Each stream includes multiple data points, such as bid and ask prices, bid and ask volumes, mid price, last traded price, and a staleness flag. These fields help protocols detect thin liquidity, outdated ticks, or halted trading and then adjust risk logic on-chain.
The equities streams run on Chainlink’s existing Data Streams infrastructure, which already secures most oracle-related DeFi value. They are live across more than forty blockchains through the Chainlink Data Standard, enabling broad integration.
Use Cases for DeFi and Tokenized Assets
DeFi teams can now build equity perpetuals, prediction markets, structured products, and synthetic ETFs that track U.S. stocks more closely. Protocols no longer need to rely on delayed quotes or narrow market hour windows that expose traders to stale prices.
Derivatives platforms, including BitMEX, Lighter, and ApeX, are already integrating the new streams for stock and ETF perpetual contracts. The pull-based update model pushes new data only when trades occur, helping reduce gas costs.
Always-on pricing also strengthens tokenized real-world asset markets that mirror on-chain listed equities. Analysts highlight that real-world asset tokenization could reach tens of trillions of dollars by 2030, underscoring the need for robust data.
Technical Design and Market Context
The 24/5 streams offer sub-second latency designed to meet institutional data standards rather than retail-style delays. Chainlink aggregates prices from multiple institutional providers and processes them through decentralized oracle networks for verification.
Metadata, such as market status and circuit-breaker-style indicators, allow protocols to pause liquidations or tighten parameters during stress. The launch coincides with growing efforts by exchanges and infrastructure firms to bring U.S. equity trading closer to a continuous, on-chain model.
