Anthropic reportedly pays $3.4 billion to take over OnePWR's 1.7GW gas generator order
The FT reports Anthropic agreed to pay $3.4 billion to take over OnePWR's 1.7GW Caterpillar generator order — the largest power-equipment purchase by an AI lab.

The Financial Times reported exclusively on November 8 (paywalled; details below carry a “reportedly” caveat throughout) that Anthropic has agreed to pay $3.4 billion for gas-fired generators to power its own data centers: in late September, the company behind Claude took over the order and purchase commitments for 1.7GW of heavy-duty generators from OnePWR Solutions, a San Antonio, Texas equipment supplier — machines OnePWR had ordered from Caterpillar roughly two years earlier but could not finance. Per the FT, it is the largest known single purchase of power-generation equipment by an AI company, and both Anthropic and OnePWR declined to comment. Reuters, Investing.com and The Economic Times carried the same line the same day.
Key points
- The price and the size: $3.4 billion (per the FT, citing a person familiar) for commitments to 1.7GW of heavy-duty gas generators — a simple division puts that near $2 million per megawatt (FourWeekMBA’s arithmetic, not an official unit price). The deal was struck in late September.
- It is not an acquisition: OnePWR itself stays independent and no employees move over. What Anthropic bought is the Caterpillar order, the purchase commitments behind it, and the engineering and construction capability needed to install the machines.
- Delivery runs in two waves: some units arrive in the near term, the rest within two years — equipment ordered two years ago, before prices surged, and the queue position is the thing that was bought.
Background
Anthropic has until now left power, chips, buildings and land to partners. The FT frames this deal as a turn: AI developers are using their financial muscle to cut out intermediaries and take direct control of generation. The backdrop is equipment lead time — the FT reports that manufacturing queues for gas turbines and heavy-duty generators are “stretching years into the future,” so whoever holds a place in line holds capacity.
The company’s own commitment schedule scales the problem. Per the FT’s recent reporting and the figures we checked in our Anthropic IPO roadshow entry, Anthropic has disclosed nearly $900 billion in computing commitments through 2045, about $69.8 billion of it due before the end of September 2027; Blackstone has warned investors it could receive a junk credit rating rather than an investment-grade one. Against roughly $150 billion in cash and liquid investments (a figure the FT cited in the same coverage), $3.4 billion is about 2.3% — but it is the first chunk of that ledger spent buying generation equipment outright.
Peers have each picked a different route. xAI bought mobile gas turbines for about $2 billion earlier this year; Alphabet acquired the energy developer Intersect in late 2025; OpenAI published its National Community Compact on November 5, promising to pay the power bills of its own data centers. Anthropic’s path is a fourth option: buy no company, rent no power, make no public pledge — just take over a two-year-old equipment order.
The facts
The figures below trace to published reports; apart from Caterpillar’s filings, every deal detail is a single-source FT account (paywalled) that neither company has confirmed.
| Item | Figure / caveat | Source |
|---|---|---|
| Deal value | $3.4 billion | FT, citing a person familiar, Nov 8 |
| Capacity | 1.7GW of heavy-duty gas generators | FT |
| Timing | Struck in late September | FT |
| Original order | OnePWR ordered from Caterpillar ~2 years ago; financing never closed | FT |
| What changed hands | Order and purchase commitments plus engineering and construction capability; no employees | FT |
| Delivery | Some units near term, the rest within two years | FT |
| OnePWR background | San Antonio supplier; claimed 400+ MW in inventory plus 800+ MW within 24 months | GlobeNewswire release, Feb 3 (via FourWeekMBA) |
| Caterpillar Q3 power-gen sales | $3.421 billion, up 30% year over year | Caterpillar 10-Q for quarter ended Sept 30, filed Nov 4 |
| Caterpillar backlog | ~$78.1 billion, up ~$6.0 billion quarter over quarter, largest gain in Power & Energy | Caterpillar 10-Q and Oct 29 earnings call |
Two numbers size the deal. The freshly filed 10-Q shows Caterpillar’s third-quarter Power Generation sales at $3.421 billion — so this one order roughly equals a full quarter of that segment’s revenue (FourWeekMBA’s comparison, about 4.4% of Caterpillar’s total backlog). Spread over 1.7GW, the deal works out near $2 million per megawatt. xAI’s $2 billion of mobile turbines came with no disclosed capacity, so no per-MW comparison exists — but the point stands that a dollar spent on generation equipment is now a separate budget line from a dollar spent on GPUs.
What others say
The FT’s account rests on a person familiar with the deal, and both companies declined to comment — that is the boundary of everything above. Beyond it:
FourWeekMBA set the deal against Caterpillar’s own filings: Q3 Power Generation sales of $3.421 billion, up 30% year over year, with the company attributing growth on its earnings call to “data center applications” and the biggest backlog gain in Power & Energy. The same analysis flags a number that does not reconcile: OnePWR’s February release described 1.2+ GW of total equipment assets, against the FT’s 1.7GW, with no third party able to split the difference.
Stifel’s head of clean energy and power told the FT that owning power infrastructure helps protect against “disruptions beyond their control.” The analysis also lines up the adjacent deals: GE Vernova taking orders for 57 aeroderivative turbines against 9 previously, with $19.5 billion in down payments over nine months; Generac carrying a $4.5 billion data-center backlog after an Amazon agreement. Outlets on two continents read the direction the same way — equipment makers are taking AI buyers’ deposits, and buyers are locking in capacity years ahead.
Our take
Our read: this money bought time, not equipment. $3.4 billion for 1.7GW is not cheap on a per-megawatt basis; what is expensive is the position — ordered two years ago, locked in before prices surged, deliverable soon. In a market where lead times run to years, the queue slot is the asset. For developers who depend on Claude, near-term supply is unaffected: this deal serves the delivery schedule of data centers Anthropic has not yet finished building. The thing worth watching is the precedent — if every frontier lab starts buying equipment capacity outright, smaller AI companies shopping for power gear after 2028 will face prices that have been bid up and queues that have been sold.
The honest catch: every deal detail here traces to a single FT source with no company confirmation. The split of the $3.4 billion between Caterpillar and OnePWR, the installation sites, the payment terms — none are reported, and OnePWR’s own 1.2GW claim still sits next to the FT’s 1.7GW unreconciled. The deal closed in late September, about six weeks before the IPO roadshow was reportedly due to start, with enterprise AI spending growth already collapsed from 42% in July to 1.5%. Whether swapping cash for generators is expansion or pre-IPO window dressing is a question the reporting does not answer.
What to watch
Dated checkpoints. Through the rest of 2026: whether the first units actually arrive on the “near term” schedule. Over the next two years: where the 1.7GW lands and how it connects — the FT says the generators serve Anthropic’s own data centers without naming a single site. Mid-November: the IPO roadshow and pricing, with this $3.4 billion outflow landing in the last reported quarter before listing. The open question: when Anthropic first talks about its power strategy in public — so far its entire position on this deal is a declined comment.
