FTSE Russell, a London Stock Exchange Group subsidiary, will use Chainlink’s DataLink service to publish its major financial benchmarks, including the Russell indices, on-chain.
The move will make FTSE Russell’s high-quality market data available 24/7 across multiple blockchains, targeting growing institutional demand for tokenised assets and next-generation financial products.
Chainlink’s DataLink acts as a secure connector, allowing traditional data vendors like FTSE Russell to send existing data feeds to Chainlink nodes for on-chain publishing, while maintaining control over data distribution and access.

FTSE Russell will start publishing its benchmarks and market data on-chain using Chainlink’s institutional DataLink service.

The rollout covers major gauges including the Russell 1000, Russell 2000, Russell 3000 and additional FTSE Russell products, and will make data available around the clock across multiple blockchains, the companies said Monday.

The Russell 1000, a large-cap US equity barometer, carries a weighted-average market capitalisation of US$1.01 trillion (AU$1.57 trillion) and is up more than 16% year to date, according to data from Google Finance.

Moving Data On-Chain

DataLink lets traditional data vendors send feeds to Chainlink node operators through existing REST or WebSocket APIs, avoiding bespoke blockchain builds while preserving control over distribution and access.

In other words, DataLink is Chainlink’s connector for big data firms. FTSE Russell can send its existing feeds through standard web interfaces, and DataLink handles the publishing to multiple blockchains. Chainlink’s nodes receive the feeds and write the data on-chain, while FTSE Russell keeps control over who can access the data and how it is distributed.

The same pipeline has been adopted by firms such as Deutsche Börse and S&P Global, and is integrated with dozens of networks serving thousands of decentralised applications (dApps).

FTSE Russell, a subsidiary of London Stock Exchange Group, said bringing regulated, high-quality benchmarks on-chain targets growing institutional demand in digital assets and tokenisation.

This marks a major step in enabling innovation around tokenized assets, ETFs, and next-generation financial products. DataLink allows FTSE Russell to securely distribute underlying data of some of our most trusted benchmarks across global on-chain markets, giving institutions and developers the same high-quality data that powers traditional finance.

Fiona Bassett, CEO at FTSE Russell.

By publishing indices through DataLink, FTSE Russell intends to enable secure, global distribution of its benchmarks to more than 2,000 blockchain applications across 50-plus networks.
