- Chainlink launched 24/5 U.S. Equities Streams to deliver context-rich onchain data for U.S. stocks and ETFs across pre-market, regular, after-hours, and overnight sessions.
- The feeds expose bid/ask, volumes, last trade, market-status flags, and staleness signals and are live across 40+ blockchains with early adopters including Lighter, BitMEX, ApeX, and Orderly.
- Integrators must manage separate session feeds with market-status-driven switching and fallbacks to handle transition edge cases and sparse off-hours liquidity.
- The product could enable equity perps, synthetic stocks/ETFs, and new lending/risk tools, while raising concerns around regulation, data-provider concentration, and weekend/holiday gaps.

The launch of Chainlink’s 24/5 U.S. Equities Streams represents a substantive step toward closing the long-observed mismatch between continuous blockchain dynamics and the time-constrained nature of traditional equity markets. For the first time, DeFi protocols will have access not just to end-of-day or standard-hours mid-price feeds, but to full depth of market information—bid/ask, volumes, last trades, and market phase—24 hours a day during U.S. trading weekdays, including pre- and post-market and overnight sessions.
On the technical front, Chainlink’s schema (RWA Advanced v11) requires protocols integrating these streams to manage three distinct session feeds (Regular, Extended, Overnight), rely on market-status flags and staleness indicators, and implement feed-switching logic that handles edge cases like session transitions and unknown or closed market statuses. While this adds complexity, it delivers sufficient granularity for applications like equity perpetuals and synthetic securities that demand risk controls and market integrity across all active hours.
Early adoption by major platforms (Lighter, BitMEX, etc.) underscores both demand and the strategic opportunity. These users aim to offer continuous trading, derivative issuance, lending, and synthetic exposure tied to equities and ETFs—market niches that have been dormant or hard to replicate in DeFi due to data limitations. The ability to tap into approximately US$80 trillion of U.S. equities represents massive runway for RWA products, especially if regulatory and liquidity risks can be managed.
However, limitations remain. Extended-hours and overnight feeds currently rely on single providers, raising concentration risk. Liquidity is thin off-hours, spreads may widen, and price jumps between sessions may lead to significant slippage. Protocols must implement mitigation (circuit breakers, smoothing, fallback to tokenized or last‐valid price) to prevent adverse outcomes. Weekend and holiday coverage remains beyond the current product scope.
From a strategic perspective, this development could shift competitive dynamics. DeFi platforms that can integrate these feeds with robust risk frameworks will be first-movers in perpetual equity markets, synthetic equities, and global access to U.S. securities. Traditional markets and incumbents may feel pressure to adapt tokenization, settlement, and custody models. Also, regulatory scrutiny will likely increase around tokenized equities, off-hours trading, and data licensing.
Open questions track around regulatory frameworks: securities laws, exchange registration, cross-border compliance. Also, whether liquidity providers will engage sufficiently during off-hours to support large trades, how market makers will price risk, and how competitive the space becomes as more protocols strive to build 24/5 or even 24/7 real-world asset (RWA) ecosystems.
Supporting Notes
- On January 20, 2026, Chainlink announced it is delivering continuous market data for U.S. equities and ETFs—including pre-market, regular hours, post-market, and overnight sessions—enabling DeFi protocols to access these markets onchain with high fidelity.
- The data provided by the 24/5 Streams includes mid-prices, best bid and ask, bid/ask volumes, last traded prices, market status flags, and staleness indicators.
- Data is live across more than 40 blockchains; early adopters include Lighter (second-largest perps DEX by volume), BitMEX, ApeX, HelloTrade, Decibel, Monaco, Opinion Labs, and Orderly Network.
- Chainlink estimates the U.S. equity market size at ~US$80 trillion, which is the total tradable equity market that these data streams aim to bring onchain.
- Risk factors include low liquidity in off-hours sessions, reliance on single provider for extended/overnight data sources, price jumps during transition between market phases, and weekend/holiday closures. Protocols are encouraged to use staleness indicators, fallback strategies (tokenized asset pricing), circuit breakers.
- The product is built on Chainlink’s RWA Advanced schema (v11); Data Streams have already seen deployment in use cases such as perpetuals, synthetic equities/ETFs, lending markets, prediction markets, and structured products.
