Cross-Chain $80 Trillion US Stock Market, Chainlink Initiates 24/5 Data Stream

This service aims to provide blockchain developers and financial institutions with continuous market data for the U.S. stock market and ETF indices, covering standard trading hours, pre-market, after-hours, and overnight trading phases. This initiative signifies the deep integration of the approximately $80 trillion U.S. stock market with on-chain ecosystems, breaking down the traditional time barriers between conventional finance and decentralized finance (DeFi).

For a long time, on-chain asset markets have faced a structural pain point: blockchain networks operate 365 days a year, 24/7, but traditional U.S. stock markets are limited to fragmented trading sessions (usually from 09:30 to 16:00 Eastern Time on weekdays).

Most previous oracle solutions only provided single price points during standard hours, leading to decentralized exchanges (DEXs) being unable to maintain accurate pricing outside trading hours. This forced developers to pause trading or bear significant quoting risks, resulting in a lack of representation of real-world assets (RWA) like U.S. stocks on-chain.

With the 24/5 data stream, on-chain platforms can now securely conduct U.S. stock trading outside traditional hours, ensuring price accuracy and enabling the development of new financial products without service interruption.

Introducing a “Pull-Based” Model to Improve High-Frequency Trading Precision and Cost Efficiency

Technically, the 24/5 U.S. Equities Streams differ from Chainlink’s traditional Price Feeds.

The latter typically use periodic update models suitable for lending platforms like Aave; the new data streams adopt a “pull” model, capable of sub-second update frequencies. This mechanism only sends updates when trades occur, significantly reducing network Gas costs associated with continuous on-chain reporting, making it ideal for high-frequency trading (HFT) and derivatives contracts.

In addition to basic price information, the data stream also includes rich metadata such as bid/ask prices, trading volume, market status indicators, mid-price, and data freshness indicators (Staleness Indicators).

These detailed data are crucial for developers building complex pricing models and risk management systems. Currently, this service is built on Chainlink’s Data Standard, which has previously supported over $27 trillion in trading volume and transmitted more than 19 billion verified messages, with proven stability and security. The service has now been deployed on over 40 blockchain networks, providing high scalability for global developers.

Derivatives Trading and RWA Ecosystem Response, Full Lifecycle Automation of Target Assets

This technological innovation has been actively adopted by several leading exchanges and RWA platforms. Derivatives exchanges BitMEX and Lighter have integrated the service for running perpetual futures contracts.

• BitMEX CEO Stephan Lutz stated that for derivatives markets, security and data integrity are paramount, and Chainlink’s 24/5 data stream is a key component of their professional-grade 24/7 equity derivatives infrastructure.
• Lighter CEO Vladimir Novakovski pointed out that this allows the platform to extend fair, low-latency perpetual contract execution beyond regular trading hours without compromising data reliability.

Additionally, platforms such as ApeX, HelloTrade, Decibel, Monaco, Opinion Labs, and Orderly Network have completed integrations, supporting equity perpetual contracts, lending platforms, and synthetic assets.

Chainlink’s ambitions go beyond just pricing services. The organization is collaborating with Swift, Euroclear, and the U.S. Securities Clearing and Settlement Corporation (DTCC) to automate corporate actions such as dividends, stock splits, and mergers. This infrastructure aims to ensure tokenized assets can automatically reflect key changes in underlying stocks without manual intervention, reducing error risks.

As the New York Stock Exchange (NYSE) also plans to launch a 24/7 blockchain trading venue, Chainlink’s data layout is enabling unprecedented alignment between on-chain market operations and traditional finance systems.
