Broadcom turns its biggest chip customer into its biggest borrower

One partner, three roles

Broadcom appears three times in Anthropic's IPO prospectus: co-designing the chips with Google, leasing the equipment, and now lending the money ¹. The filing says it agreed to lend Anthropic up to $42 billion for infrastructure spending↗, in notes that can convert into Anthropic shares, with none expected to be sold before the listing completes ¹². Amazon, by contrast, supplies cloud and distribution, and stops there ¹.

A third of the lease, a twelfth of the bill

The note could finance about a third of Anthropic's $125.2 billion five-year commitment to lease tensor processing unit compute ¹², roughly a twelfth of the $518 billion in planned cloud and infrastructure obligations ³. The exchange: Anthropic becomes the largest customer in Broadcom's chip design business next year ¹, at a listing that could value the lab at more than $2 trillion ³.

The conflict is disclosed, in writing

The company that prices Anthropic's compute is also the bank for it. The prospectus discloses "potential conflicts of interest" that might affect Anthropic's access to computing power, and says certain defaults could make a substantial portion of the lease immediately due while limiting use of the $42 billion facility to cover them ². Anthropic has already deposited cash into a restricted account for Broadcom's benefit ².

The ramp behind the loan

Broadcom can carry the bet. Quarterly revenue has tripled since late 2023 to a record $29.6 billion, $16.7 billion of it AI silicon, up 221 percent ⁴⁸. Management guides AI revenue to about $115 billion in fiscal 2027 and $230 billion in 2028↗ ⁴, and chief executive Hock Tan says Anthropic is "on track to become our largest XPU customer in 2027 and sustain that in 2028"; 10 gigawatts of the roadmap is Anthropic alone ⁴.

The other side: contingent, and called low risk

Chief financial officer Amie O'Toole frames it as "modest residual value guarantees, which are contingent liabilities we view as low risk," and has "nothing to announce today" on a maximum figure ⁴. A secondary reading of the filings describes a backstop behind an Apollo and Blackstone-led private-credit package of roughly $35 billion↗, with senior-tranche exposure of $29 billion to $31 billion depending on the disclosure, and no payouts so far ⁶. Seaport's Jay Goldberg: "Nvidia is putting in place a massive amount of its balance sheet, and Broadcom is having to follow suit" ¹.

What to watch

The borrower lost $42 billion in 2025 on revenue of almost $4.6 billion ³. The match with the note cap is coincidence; about $34 billion of the loss was an accounting charge on financing that could turn into shares, not cash spent ³. Revenue is outrunning it: $4.73 billion in Q1 2026, more than $11.5 billion in Q2 ⁷. Because the notes can convert into Anthropic shares ¹, the IPO is Broadcom's repayment path: it exits in stock, and the listing's buyers supply the exit. Rothschild's Robert Leitao calls it "quite a concentrated bet" on two companies generating enough revenue to support all the financing ¹.
