Chainlink Launches 24/5 Stock Data Feeds, Bringing About $80 Trillion of the US Stock Market On-Chain

On January 20, Chainlink announced the launch of 24/5 U.S. Equities Streams—marking the first time DeFi gains access to pre-market, after-hours, and overnight U.S. stock market data—enabling the ~$80 trillion U.S. stock market to operate continuously on-chain. This data feed delivers high-frequency, cryptographically signed market data 24/5, covering not only mid-prices but also bid/ask prices and volumes, last trade price, market status indicators, and data freshness metrics. It provides full market context for on-chain trading, clearing, and risk management. Chainlink noted the solution has been deployed across 40+ blockchains, supporting a range of Real World Asset (RWA) use cases: U.S. stock perpetual swaps, prediction markets, synthetic stocks, lending, and structured products. Platforms including Lighter, BitMEX, ApeX, and Orderly Network have adopted the feed, driving growth of a continuous on-chain U.S. stock market. Chainlink added the 24/5 feed resolves the structural mismatch between traditional U.S. stock trading hours and blockchain’s 24/7 operation—a key step toward large-scale on-chainization of institutional-grade U.S. stock assets.
