Anthropic is in early-stage talks to lease up to 1 gigawatt of computing capacity from Stream Data Centers in a roughly $40 billion buildout, according to a post on X. The leasing arrangement would pair Google TPUs and Nvidia GPUs to expand the AI company's internal infrastructure footprint.
The leasing arrangement follows Anthropic's signing of $517 billion in compute agreements over the past 11 months, according to industry estimates. That total includes deals with Amazon Web Services, Google Cloud and others negotiated to secure the chip supply needed to train and run large language models at scale.
Stream Data Centers operates data centers in the United States and has attracted investment from major cloud operators and financial backers. A 1GW facility represents substantial electrical capacity; hyperscalers typically consume between 100 megawatts and several gigawatts per major cluster. The $40 billion figure cited in the talks encompasses infrastructure construction, hardware procurement and operational ramp-up over multiple years.
Training advanced language models requires sustained access to thousands of specialized processors. The company has previously disclosed that Google has committed up to $2 billion in cloud credits and Nvidia has made chips available as Anthropic expands its operations. A dedicated leased facility with company-selected hardware gives Anthropic greater control over latency, power delivery and upgrade cycles than shared cloud infrastructure alone.
The talks remain in early stages and deal terms may shift. Neither Anthropic nor Stream Data Centers has made public statements confirming the arrangement or its final shape.
Anthropic's compute agreements total to roughly one-third of the $1.5 trillion in AI infrastructure spending projected across the industry through 2030 by major research firms. The company is also competing with OpenAI, which has raised billions for its own infrastructure buildout and secured access to xAI's data center capacity through a separate arrangement. If Anthropic completes the Stream facility lease, the company will have moved from cloud-dependent operations to owning material shares of its underlying compute layer within 18 months of its prior model releases.
