Broadcom Will Lend Anthropic Up to $42 Billion to Lease TPU Capacity

Anthropic is not only buying compute. It is borrowing from the company that helps build it. A prospectus reviewed in reporting this week says Broadcom has agreed to lend the lab up to $42 billion to finance infrastructure spending. The instrument is a convertible note. It could cover about a third of a $125.2 billion commitment Anthropic has made to lease tensor-processing-unit capacity for five years. Those TPUs are Google-designed chips Broadcom has co-developed across several generations. Anthropic said it does not expect any of the notes to be sold before the IPO closes. That is three roles on one counterparty: chip supplier, equipment lessor, and lender. The filing flags the conflict. Amazon, by contrast, shows up in the same document mostly as cloud and distribution for Claude. Broadcom is in the machine room and on the term sheet. How the Money Sits The $42 billion is capacity, not cash already wired. Broadcom can name a financing partner. The debt can convert into Anthropic equity, which would turn a vendor into a shareholder of a customer that is talking about a listing near $2 trillion. Anthropic put cash into a restricted account for Broadcom’s benefit in April 2026 and may have to add more under certain conditions. Some defaults, the prospectus cautions, could accelerate a large slice of lease payments and limit access to the $42 billion facility for those obligations. The lease itself is the asset. An April partnership with Broadcom and Google promised multiple gigawatts of next-generation TPU capacity starting in 2027. If that ramp holds, Anthropic is on course to become Broadcom’s largest compute customer next year. Broadcom has projected AI chip revenue around $115 billion in fiscal 2027 and $230 billion in fiscal 2028. A customer that large, financed by the seller, is how those numbers get a path. The Private-Credit Layer Underneath This is not Broadcom’s first signature on Anthropic’s chips. In June, Apollo and Blackstone anchored a roughly $35 billion private-credit package — one of the largest of its kind — secured against AI hardware. A special-purpose vehicle buys the TPUs, including Google designs Broadcom helps make, and leases them to Anthropic. Lease payments service the debt. Holding the hardware in the vehicle keeps it off Anthropic’s balance sheet, which matters for a company heading to public markets with heavy losses. Interest on senior slices of that stack was backstopped by Broadcom. A guarantee that the chipmaker will cover a missed payment is what made the paper cheaper. Reported exposure on those senior tranches has been framed in the high-$20 billions to low-$30 billions, depending on the disclosure. The new $42 billion convertible is the lab-side facility sitting beside that structure, not a replacement for it. Together they are how a five-year, $125.2 billion lease gets funded without Anthropic writing the whole check from cash. Broadcom has also talked about a wider platform — AI XPV in some descriptions — that could scale toward 20 gigawatts of capacity through 2028 for labs including Anthropic and, in the pitch, OpenAI. The first batch was tied to Anthropic capacity at sites run with operators such as Fluidstack. The $42 billion note is the customer-financing chapter of that same build. Why Vendors Are Lending Nvidia spent the last two years using its balance sheet to help customers buy Nvidia chips. Broadcom is running the same play on a custom-silicon book it shares with Google. If the buyer cannot finance the lease, the seller’s 2027 revenue does not print. Lending is distribution. The risk runs the other way. If Anthropic’s usage lags the lease, Broadcom is both unpaid vendor and creditor. If Anthropic lists and the convert is in the money, Broadcom owns a piece of a customer whose orders it also prices. The prospectus says as much: Broadcom’s decisions on pricing and hardware could affect Anthropic’s ability to get enough compute. That sentence is a risk factor because it is a real tension, not a lawyer’s habit. Anthropic’s own numbers in the same filing make the tension sharper. Revenue near $4.6 billion in 2025, an operating loss above $8 billion in some tallies, infrastructure commitments in the hundreds of billions, and a risk section that already warns of catastrophic or existential harm from the models. The chip loan does not appear in the extinction paragraph. It is how the extinction paragraph gets a data center. What to Watch Whether the notes stay unsold until after the IPO, as the filing expects. How much of the $42 billion is drawn against the 2027 TPU ramp. Whether conversion terms surface in the public S-1. Broadcom’s fiscal 2027 AI revenue against the $115 billion guide. Any default language that accelerates the $125.2 billion lease. A lab that warns it might lose control of the technology is leasing $125 billion of the machines that run it, with up to $42 billion of the bill financed by the company that builds the machines. That is the AI trade in one contract.
