Chainlink crypto brings US GDP data to 10 blockchains—Who is using it?

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.

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.
