Broadcom to lend Anthropic up to $42B to lease chips: report

Anthropic’s IPO prospectus reveals a significant partnership with chip maker Broadcom, worth up to $42 billion. This arrangement enables Anthropic to lease its computing chips and provides Broadcom with a central role in the AI lab’s infrastructure development. Broadcom’s involvement is distinct from other major partners like Amazon, which primarily supply cloud infrastructure for Anthropic’s model Claude.

As part of the complex relationship, Broadcom has agreed to lend Anthropic up to $42 billion to finance its infrastructure spending. In return, Anthropic is poised to become Broadcom’s largest customer in chip design next year, marking a prime example of reciprocal spending in the AI sector.

Robert Leitao, managing partner of Rothschild & Co., notes the concentrated bet on Anthropic and Broadcom, as the AI lab prepares for a potentially $2 trillion valuation through its public offering.

The financing arrangement may involve converting debt instruments into Anthropic shares, with Anthropic not expecting any notes to be sold before its IPO. The convertible note Anthropic plans to issue could finance about a third of its $125.2 billion commitment for a five-year lease of tensor processing unit (TPU) computing capacity, developed jointly by Alphabet’s Google and Broadcom.

Broadcom’s financing strategy follows Nvidia’s approach of leveraging its financial strength to bolster chip sales. Seaport Research analyst Jay Goldberg comments on Broadcom’s need to follow suit in light of the significant commitments made by AI labs.

However, Anthropic has disclosed potential conflicts of interest due to Broadcom’s role in supplying hardware and acting as a financing partner. The AI lab warns that Broadcom’s decisions on pricing and hardware could affect its ability to secure sufficient computing infrastructure.

Anthropic deposited cash into a restricted account for Broadcom’s benefit in April 2026 and may be required to contribute additional amounts in certain circumstances. In case of payment or performance defaults, a substantial portion of Anthropic’s lease obligations could become immediately due, limiting its ability to utilize the $42 billion financing facility.
