Broadcom Will Lend Anthropic $42B to Rent Broadcom's Own Chips

Broadcom is lending its customer the money to pay for Broadcom's own chips.

Reuters laid out the details on the morning of October 1, citing Anthropic's IPO prospectus. Broadcom will provide up to $42B in financing. The money goes toward leasing TPU (tensor processing unit, Google's AI chip) capacity, which Broadcom co-develops with Google.

The same day, Bloomberg reported that Anthropic aims to start marketing its IPO the week of November 9. The valuation under discussion runs as high as $2 trillion.

Anthropic Becomes Broadcom's Biggest Customer

The relationship has three legs: compute supply, equipment leasing and financing. On April 6, Anthropic announced a deal with Google and Broadcom for multiple gigawatts of next-generation TPU capacity. That capacity starts coming online in 2027.

In its September 2 earnings, Broadcom said AI semiconductor revenue would reach about $115B in fiscal 2027 and $230B in fiscal 2028. Anthropic is expected to be its largest custom-chip customer in 2027.

A large part of that target rests on one customer. That customer is not yet profitable. According to the prospectus Reuters saw on September 28, Anthropic had about $4.6B in 2025 revenue and an operating loss above $8B.

The market did not read this as an order story.

It read it as a credit story.

How the Loan Works

The financing takes the form of convertible notes. Under certain conditions, Broadcom's claim can be converted into Anthropic shares. Anthropic says it does not expect any notes to be sold before its IPO closes.

In this structure, Broadcom's revenue is tied to Anthropic's ability to pay twice. Once as a supplier, once as a lender.

The prospectus spells out that link. Certain payment or performance defaults could make the lease obligations due immediately. At the same time, access to the $42B facility could be restricted. In a bad stretch for Anthropic, the debt comes due early and the credit line closes.

The filing also flags "potential conflicts of interest." Broadcom's pricing and hardware decisions could affect Anthropic's ability to secure enough compute.

How the Stock Reacted

Broadcom closed October 1 at $343.64, down 2.15%. The Nasdaq Composite rose 0.44% the same day.

Treasury yields also hit their highest since 2002 that day, with the 10-year touching 5.33%. When rates rise, long-dated, debt-funded receivables look more expensive. Sources do not separate how much of the drop came from the loan and how much from rates.

Robert Leitao of Rothschild & Co Redburn told Reuters the risk is concentrated: "quite a concentrated bet right now on two companies."

The Part That Doesn't Fit

Broadcom is not alone. One analyst told Reuters that Nvidia is committing a large share of its balance sheet to customer financing, and Broadcom is having to follow.

Nor is Broadcom carrying the risk by itself. The company had already set up partnerships with Apollo and Blackstone to finance customers' chip purchases. As of August 2, it had reportedly not extended any financing.

Anthropic also deposited cash into a restricted account for Broadcom's benefit in April, and may need to add more in some cases. So part of Broadcom's claim is secured by cash from the start.

What Remains Open

The loan's rate, maturity and conversion price have not been reported. Once the prospectus is public, those three numbers will show how much of Broadcom's sale is paid in cash and how much in stock.
