Chainlink, a blockchain data infrastructure firm, has teamed up with FTSE Russell, one of the world’s leading index providers, to bring its market indices onto public blockchains for the first time.
The official announcement revealed that the partnership will bring data from major indices, “including the Russell 1000, Russell 2000, Russell 3000, and FTSE 100,” on-chain through Chainlink’s DataLink system.
It will also include other equity, currency, and digital asset benchmarks, expanding access to verified financial data across blockchain networks.
For the first time, FTSE Russell is placing its market index data on public blockchains, making it directly accessible and verifiable. FTSE Russell manages indices that serve as performance benchmarks for an estimated $18 trillion in global assets.
According to Chainlink, this step allows financial institutions and developers to reference official benchmark data without relying on intermediaries, supporting more transparent use of market information in digital systems.
Benchmarks meet blockchains
DataLink is a system that connects data providers with blockchain networks, allowing them to share information securely without creating their own infrastructure. It uses Chainlink’s existing network to deliver verified data to on-chain applications and has been used widely across blockchain markets for several years.
Fiona Bassett, CEO of FTSE Russell, said the company is using Chainlink to make its index data available on blockchains in a secure way. She explained that the goal is to make FTSE Russell’s benchmark information securely available across blockchain networks.
“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,” said Bassett.
Sergey Nazarov, Co-Founder of Chainlink, described the collaboration as a key step in connecting established financial data providers with blockchain systems. He said the integration shows how data from recognized institutions can be securely transmitted on-chain, giving markets direct access to verified benchmark information.
Chainlink’s broader push
In recent months, Chainlink has expanded its data operations through several major integrations aimed at improving access to real-world financial and economic data on blockchains.
In August, Chainlink introduced new Data Streams that bring real-time price data for U.S. equities and ETFs, like SPY, QQQ, Apple, Nvidia, and Microsoft, onto 37 blockchain networks. The system offers sub-second price updates, helping DeFi platforms and blockchain apps use precise market data for trading and financial products.
Last month, BNB Chain integrated Chainlink’s data services to bring official U.S. Department of Commerce statistics, such as GDP, PCE Price Index, and Real Final Sales, on-chain. This connection allows developers to build blockchain applications that reference verified government data directly, without depending on centralized intermediaries.
