AI supercomputers have become increasingly expensive. Since 2019, the cost of the computing hardware for leading supercomputers has increased at a rate of 1.9x per year. In June 2022, the most expensive cluster was Oak Ridge National Laboratory Frontier, with a reported cost of $200M. Three years later, as of June 2025, the most expensive supercomputer is xAI’s Colossus, estimated to use over $7B of hardware.

Data come from our AI Supercomputers dataset, which collects information on 728 supercomputers with dedicated AI accelerators, spanning from 2010 to the present. We estimate that these supercomputers represent approximately 10-20% (by performance) of all AI chips produced before 2025. We focus on the 502 AI supercomputers which became operational in 2019 or later, since these are most relevant to modern AI training.

When cost figures are not explicitly reported, we estimate the cost of a data center by first estimating the hardware costs from chip quantities and public pricing information. We then factor in the expected cost of additional hardware such as networking switches and CPUs. Notably, we do not include the cost of power generation or data center construction. All cost figures are inflation-adjusted to January 2025 dollars.

For more information about the data, see Pilz et al., which describes the supercomputers dataset and analyzes key trends, and the dataset documentation.
