Chainlink announced again on Tuesday, September 1, about its data feeds that relay official US economic figures across ten public blockchains.
It enables blockchains to have access to GDP, inflation, and private spending, but the agreement started in August 2025.
Chainlink crypto connects blockchains with government data
The figures come from the US Bureau of Economic Analysis [BEA], which publishes some of the country’s most closely watched economic reports.
Through its work with the US Department of Commerce, Chainlink makes three measures available to blockchain applications: real GDP, the Personal Consumption Expenditures [PCE] Price Index and real final sales to private domestic purchasers.
GDP tracks the size and growth of the economy. The PCE index measures changes in consumer prices, while private domestic sales offer another view of demand from households and businesses.
There are two forms of each measure; the first shows the latest reported level of each measure, whilst the other shows the change of each measure during the quarter, and it creates six data feeds.
Supported chains are Arbitrum, Avalanche, Base, Botanix, Ethereum, Linea, Mantle, Optimism, Sonic, and ZKsync.
The role of Chainlink is to deliver those figures in a format that blockchain-based services can read and use automatically, while the BEA still produces and publishes the original figures.
What could the data feeds be used for?
One possible use is a prediction market that allows participants to forecast GDP growth or inflation, and the prediction settles when the latest government figures are released.
Developers could develop financial products with terms that change in response to changes in inflation or economic growth, and lending platforms may also use the information when varying their risk controls.
But these remain possible applications; they are not confirmed deployments.
Furthermore, there is no assurance of additional demand for LINK, and its effects will manifest only if developers choose to use the feeds and create apps that could increase users.
Final Summary
- Chainlink brings six different US economic data feeds to marketplaces across ten leading public blockchains.
- It launched in 2025, and the number of applications currently reliant on it is unknown at this time.
