Overview

Our AI Chip Owners hub estimates how the world’s AI compute is distributed among major companies and customer categories. This is an open research project that relies on company disclosures and estimates from third-party analysts, building on our AI Chip Sales hub, which estimates total AI chip sales. This hub tracks ownership, not usage — most frontier AI developers do not own the chips they use for training and inference. This works is intended to inform the researchers and the public about the strategic landscape of the inputs to AI progress.

The data is available on our website as a visualization or table, and is available for download as a ZIP file.
