Anthropic has purchased $3.4 billion worth of Caterpillar natural gas turbines to address power supply challenges amid soaring AI compute demand, marking a shift from its usual approach of renting computing resources.

Anthropic, a leading artificial intelligence firm known for typically leasing rather than owning physical infrastructure, has taken a significant step into energy asset ownership by investing $3.4 billion in natural gas turbines. These turbines, manufactured by Caterpillar, are capable of producing up to 1.7 gigawatts of electricity, representing a substantial capacity boost for Anthropic’s compute needs.

This development comes amid a growing power crunch affecting AI companies due to surging demand for compute resources necessary to train and run advanced AI models. Traditionally, Anthropic relied on renting compute power; for example, its S-1 filing in May revealed a $1.25 billion per month contract with SpaceX subsidiary xAI for computing services through May 2029, with intentions to secure additional similar contracts.

However, escalating challenges in securing reliable power have likely prompted this strategic pivot. The natural gas turbine market is experiencing long backlogs extending into the early 2030s, and delays connecting new generation to electrical grids create further uncertainty. These factors may have compelled Anthropic to acquire generating capacity directly.

The turbines were initially ordered by equipment supplier OnePWR a few years ago, but OnePWR failed to secure financing to finalize the deal. Although Anthropic had initially planned to purchase the turbines from OnePWR, it ultimately bought them directly from Caterpillar, possibly to avoid competitor acquisition and ensure control over this critical energy resource.

Anthropic’s move reflects broader industry trends, as major tech players including Google, Amazon, Microsoft, and Meta have announced plans to build or acquire natural gas power plants to supply their data centers independently from public grids. This trend has revitalized natural gas extraction methods like fracking, with U.S. data centers projected to consume more natural gas than Germany and Japan combined by 2035.

Nonetheless, this reliance on natural gas carries financial risks. Analysts warn that natural gas prices could more than triple in some markets by the end of the decade due to elevated demand and other factors. Should prices surge, Anthropic’s substantial investment could lead to significant financial implications.

In summary, Anthropic’s $3.4 billion turbine purchase marks a notable strategic shift to owning critical infrastructure as it confronts the power demands and uncertainties in the evolving AI compute landscape. This move underscores the growing intersection between AI development and energy infrastructure planning, with significant economic and environmental considerations.
