Chainlink opens 24/5 US stock market data stream: $80 trillion market officially on the chain

【Blockchain Rhythm】Chainlink recently announced a significant update—officially launching the 24/5 US stock and ETF data feed service. This update is quite meaningful.

In simple terms, the power of this data feed lies in breaking the mismatch between traditional US stock trading hours and the blockchain’s 24/7 operation. Previously, US stock data could only be accessed during trading hours. Now, pre-market, after-hours, and overnight trading data are all available on-chain, meaning the approximately $80 trillion US stock market can truly operate continuously on the blockchain.

From a technical perspective, this data feed supports 24/5, high-frequency, encrypted market data delivery without interruption. It includes not just mid-prices but also bid-ask prices, trading volume, latest transaction prices, market status indicators, and data freshness metrics—providing a complete market context for on-chain trading, clearing, and risk management. This is a real necessity for contracts and liquidation algorithms.

Currently, this solution has been deployed on over 40 blockchains, supporting a wide range of applications: perpetual US stock contracts, prediction markets, synthetic stocks, lending, structured products, and more. Well-known trading platforms like Lighter, BitMEX, ApeX, and Orderly Network have already integrated it, demonstrating a good pace of ecosystem adoption.

Essentially, this is a key step in driving the large-scale on-chain listing of institutional-grade US stock assets. As the RWA (Real-World Asset) concept continues to heat up, the demand for diversified on-chain assets is growing stronger. Improving such infrastructure will substantially benefit the development of the entire ecosystem.
