Anthropic reportedly spends $3.4bn to build its own gas power for data centers

Anthropic has struck a $3.4bn deal to generate gas-fired power for its data centers, the Financial Times reported. According to the FT’s public summary, the AI lab went around traditional suppliers to secure scarce equipment as demand for energy surges.

The full article is behind a paywall, and aiholics.com could not open it. We found no announcement of the deal from Anthropic, so this report rests on the FT’s headline and summary alone. The counterparty, the capacity, the sites and the timeline are not in the public text, and none are stated here.

What the public summary says and leaves out

The FT’s two public lines establish three things: the size of the deal, its purpose (gas-fired generation for data centers) and its route (bypassing the usual suppliers because equipment is scarce). Nothing else is confirmed. Because Anthropic’s own account is not available, the description should be read as reported, not confirmed.

A deal landing amid a data center backlash

The timing matters because of the politics around data centers and Anthropic’s coming stock market debut. CNBC’s headline on its own report says the Anthropic IPO is meeting an AI backlash after the midterms showed what it called a stinging rebuke of data centers. A gas-fired build-out is the kind of project that can draw scrutiny in that climate, though neither outlet’s public text says how this deal will be received.

The move also shows how far AI labs now reach into energy supply. Rather than buying power only through utilities and established equipment makers, Anthropic is, in the FT’s account, securing generation capacity itself. We covered the same pressure from the other side of the industry when OpenAI pledged to cut a Georgia campus’s power draw in a crunch. Investors weighing the offering, which is open to UK savers through six brokers, will likely want to know how such infrastructure commitments are funded and disclosed.

What readers can take from it so far

For now, nothing changes for Claude users: the report concerns how Anthropic’s data centers are powered, not products or pricing. The open questions are the ones the public summary does not answer. Who supplies the equipment, how much power it will produce, where it will operate, and how Anthropic plans to address local concerns about emissions and costs. We have no statement from Anthropic on the deal, and we will update this article if the company or the FT’s reporting adds details.
