The figure buried in Anthropic’s IPO prospectus is the kind that makes underwriters pause: a lender prepared to advance up to $42 billion to a company whose main plan for the money is to rent chips from the lender itself.
Broadcom has agreed to provide up to $42 billion in financing to Anthropic to cover infrastructure spending, according to the AI lab’s prospectus, which Reuters cited on October 1. The convertible debt is sized to cover roughly one-third of Anthropic’s five-year commitment to lease TPU compute worth $125.2 billion.
The structure hands Broadcom two roles at once. It is the hardware supplier whose chips Anthropic will rent, and it is the financier underwriting the rental. The prospectus flags the overlap directly, describing the dual position as a “potential conflict of interest.”
Broadcom can also bring partners into the financing, and the debt can later convert into Anthropic shares, according to the filing. The conversion option is what turns the loan into something closer to a wager. Broadcom collects interest and rent if the plan works, and it holds equity that appreciates as Anthropic’s value climbs. If Anthropic stumbles, the lender is exposed to a falling asset on top of its credit risk.
The scale of the bet is laid out in the same document. The prospectus says Anthropic will become the largest customer of Broadcom’s chip design business next year, and it describes a valuation of up to $2 trillion for the AI lab.
Robert Leitao, a managing partner at Rothschild & Co, put the market’s view plainly. Investors, he said, are wagering that both companies can earn enough revenue to support the entire financing arrangement.
Anthropic, founded in 2021 by former OpenAI researchers led by Dario Amodei, has grown into one of the leading builders of large language models, competing with OpenAI and Google through its Claude family of systems. The company has leaned on outside capital and outside clouds, taking investments from Amazon and Google and running its models on their infrastructure. Its appetite for compute has grown faster than its revenue, which is what makes a $125.2 billion lease commitment, and a lender willing to fund a third of it, a material event.
Broadcom, run by chief executive Hock Tan, has become a quiet pillar of the AI buildout. Its custom-chip unit designs the accelerators that Google, Meta and other hyperscalers use to run AI workloads, and demand for those chips has pushed its revenue and share price sharply higher over the past two years. Anthropic’s lease commitment would make it the single largest customer of that unit, locking in demand for Broadcom’s designs regardless of how the broader AI chip race plays out.
The deal also tightens the knot between Anthropic and the chip ecosystem Broadcom already serves. Broadcom co-designs the TPU accelerators that Google uses, and Anthropic has trained and run its models on Google’s cloud since early in the company’s life. A five-year lease that routes Anthropic’s compute bills through Broadcom extends that relationship from the cloud layer down to the silicon.
The numbers in the filing put the financing in context with Anthropic’s trajectory. A valuation of up to $2 trillion would place the company, still best known for Claude, above most public technology firms, and it rests on revenue projections that have not yet been tested against a public market. The financing is the mechanism meant to close the gap between those projections and the compute capacity they assume.
The arrangement is notable for who is doing the lending. In most AI infrastructure deals, a lab borrows from banks or investors to pay an unrelated supplier. Here the supplier is also the creditor, which doubles Broadcom’s interest in Anthropic’s solvency and deepens its hold over the customer. The fact that the conflict is disclosed in the prospectus suggests the company’s bankers wanted the relationship laid out in the open before investors decide.
The circularity carries an echo of an older pattern. Equipment makers in earlier booms financed their own customers’ purchases, recording revenue against money they themselves had lent. Broadcom’s financing is convertible debt rather than vendor loans, and the deal’s defenders note that a third of the lease is still covered by outside money. But the question the market is asking is the same one those earlier deals raised: whether the revenue is durable if the customer’s bill is paid with the supplier’s credit.
The $2 trillion figure is where the argument ends. If Anthropic reaches that valuation, the debt converts and Broadcom’s loan becomes one of the more profitable underwriting decisions of the boom. If it does not, the rent still comes due. Leitao’s phrasing, that the market is betting both companies can earn enough to support the arrangement, is the polite way of saying the bet runs in both directions.
