Anthropic has signed a $35bn cloud deal with Nvidia-backed Lambda

Anthropic has committed $35bn to a cloud provider most people have never heard of, for capacity in a Texas data centre being built by a former bitcoin miner.

The Wall Street Journal reported the Lambda agreement on Monday, and Reuters confirmed it with a person familiar with the matter.

Neither company has announced it, and no term was disclosed. We have not independently verified the report, which rests on unnamed sources.

Lambda is backed by Nvidia, and the structure around the deal is where it gets interesting. Lambda holds the lease on a data centre in Nueces County, Texas, developed by Hut 8, while Nvidia has a separate arrangement with Hut 8 to secure the capacity, and Lambda deploys Nvidia chips into it.

Follow that chain, and Nvidia appears at three points in a transaction it is not formally party to. It has invested in the tenant, contracted for the site, and supplies the hardware that fills it.

The chipmaker has been building exactly this apparatus all year, helping cloud providers secure the financing and property they need to deploy its systems.

It is the same logic behind the revenue-sharing programme it introduced in July and paused last week after internal antitrust concerns.

For Anthropic, the deal is one of several very large numbers signed in quick succession. It agreed to spend $45bn over six years with Nscale for capacity in West Virginia earlier the same month.

Amazon has separately said Anthropic will spend more than $100bn on AWS over the next decade, for five gigawatts of capacity and access to Trainium3 silicon. Set against that, $35bn is not the largest commitment on the list.

The pattern is by now well established. Anthropic signed a $9.1bn, 20-year deal with bitcoin miner Riot Platforms, a $10bn arrangement with a week-old cloud startup, and a larger package with Google and Broadcom.

Anthropic has also been in early talks to lease $10bn of compute from Meta, which is an unusual conversation between two companies that compete for the same engineers and the same enterprise budgets.

What links them is a preference for many suppliers over one. A company whose product is a single model family has an obvious interest in not depending on a single provider of the compute that runs it.

There is a concentration question underneath the diversification. Spreading contracts across many providers looks like resilience until you notice that most of them are deploying the same vendor’s chips in buildings that vendor helped secure.

Bitcoin miners keep appearing in these deals for unglamorous reasons. They hold grid connections, land and power contracts that took years to assemble, which are now the scarcest inputs in the industry and considerably harder to acquire than chips.

Hut 8 is the second miner-turned-operator in Anthropic’s supply chain after Riot. The conversion of crypto infrastructure into AI infrastructure has been one of the quieter structural shifts of the past two years.

Texas is doing a lot of work in these announcements too. Cheap land, a separate grid and a permitting regime that moves faster than most have made it the default answer for anyone who needs a gigawatt in a hurry.

None of these commitments is a cost that has already been incurred. They are multi-year obligations against revenue that has been growing quickly but has not yet reached the scale the contracts assume.

Anthropic’s run rate has been rising fast enough to make the arithmetic defensible, having passed $30bn earlier in the year. Whether it reaches the level these contracts assume is a different question from whether it is growing.

That is the bet in every one of them. Anthropic is contracting now for the capacity it will need if demand continues, at prices agreed before anyone knows whether it will.
