Blackstone has pitched a debt package of at least $36 billion to finance Anthropic's purchase of Google TPU chips, according to sources familiar with the proposal. The investment firm is in early talks with investors to backstop the artificial intelligence company's infrastructure deal, with terms still under discussion.
A $36 billion debt package would rank among the largest infrastructure financings in recent years. Anthropic, founded by former OpenAI executives Dario and Daniela Amodei, has raised $9.2 billion in equity funding through 2024 and has been expanding its computing capacity to compete with rivals including OpenAI and Google.
The Google TPU chips are specialized processors designed for machine learning workloads. Large language model developers require substantial quantities of these accelerators to train and serve their models at scale. Anthropic has previously announced major compute commitments, including a $30 billion partnership with Amazon Web Services in 2024 to purchase custom chips and cloud services over five years.
Blackstone's proposal marks an early-stage pitch, according to sources. The firm has not closed commitments from investors, and the terms and structure of any final deal remain open to negotiation. Debt financing for chip infrastructure deals is not unprecedented, but a package of this magnitude involves the sheer costs now required to remain competitive in frontier AI development.
Anthropic has not made a public announcement about the Blackstone financing or the scope of its planned chip purchases. The company has been more cautious about publicizing capital raises compared to some competitors, instead focusing on product deployments and safety research. Chip scarcity and pricing power have become central strategic concerns for AI labs, with leading companies bidding aggressively for GPU and TPU allocations from manufacturers and cloud providers.
If the debt deal proceeds near the $36 billion mark, it would provide Anthropic with a non-dilutive way to fund infrastructure without issuing additional equity. The combination of equity backing and debt financing has become a common structure for capital-intensive AI ventures seeking to minimize shareholder dilution while accessing the scale needed to train larger models.
At $36 billion, the proposal is roughly four times the size of Anthropic's largest single equity round to date. Debt structures for compute infrastructure typically carry repayment terms tied to the generating assets or the company's cash flows, making them sensitive to Anthropic's ability to monetize its models and services through its Claude API and other commercial channels. The document to watch is whether Blackstone closes investor commitments and what terms emerge around repayment schedules and collateral.
