Broadcom to Lend Anthropic Up to $42 Billion

Broadcom has agreed to lend Anthropic up to $42 billion to finance the leasing of processing capacity in TPUs, according to Anthropic's IPO prospectus revealed by Reuters on Thursday (1st). On the same day, Bloomberg reported that the Claude developer aims to go public as early as mid-November, with a formal presentation to investors starting the week of November 9, and a debut before Thanksgiving on November 26.

Anthropic had not publicly commented on the schedule described by Bloomberg at the time of writing. According to the agency, discussions are ongoing and the timeline could change, but the company still expects to complete the listing by year-end.

Supplier, Lessor, and Lender

The loan comes in the form of convertible notes in Anthropic's stock. According to the document, the securities cover about one-third of the $125.2 billion commitment that Anthropic has undertaken in a five-year TPU capacity contract. Broadcom may bring in a financing partner to share the exposure, and Anthropic stated in the prospectus that it does not expect any of these notes to be sold before the IPO.

This arrangement places Broadcom in three roles at once: chip designer, capacity lessor, and lender. The prospectus itself highlights this. Anthropic lists "potential conflicts of interest" and warns that Broadcom's decisions regarding pricing and hardware may affect its ability to obtain sufficient computing infrastructure. The expectation cited by Reuters is that Anthropic will become Broadcom's largest computing customer by 2027, when the next generation of TPUs comes online.

The structure follows a pattern that the market has come to call circular financing: the supplier lends money for the customer to purchase the product from the supplier itself. The difference here is the scale. $42 billion is more than nine times Anthropic's projected 2025 revenue.

The Numbers in the Prospectus

The document, whose content was revealed at the end of September, shows a revenue of nearly $4.6 billion in 2025, twelve times that of the previous year, and an operating loss exceeding $8 billion during the same period, driven by computing expenses. Nearly a quarter of the revenue came from two clients, and the company acknowledges in its risk factors that many of its largest buyers do not have long-term contracts and may reduce or halt spending.

The valuation being discussed reaches $2 trillion, according to reports from Bloomberg and other outlets. In the Series H round in May, the company was valued at $965 billion after funding. If the November figure is confirmed, the listing would become the largest in history, surpassing SpaceX's recent debut.

Anthropic had confirmed in June that it had confidentially submitted a draft of the S-1 form to the SEC, the first formal step in the process. The delay from October to November had already been reported last week.

What Corporate Buyers Should Read Here

For CIOs expanding contracts with Anthropic, the prospectus provides the first detailed account of the supplier's infrastructure dependency, drafted by the supplier under legal responsibility. Two points weigh heavily on the risk assessment. The first is concentration: the capacity to serve models largely relies on a $125.2 billion contract with a single chip partner, who is now also a lender. The second is margin: with an operational loss higher than revenue, current API prices reflect a company that is still burning cash to grow.

There is also another perspective. Going public requires Anthropic to disclose audited quarterly results, something that private venture labs do not provide to corporate clients. For those negotiating multi-year contracts, public information about cash, customer concentration, and capacity commitments is worth more than any commercial promise.

For Broadcom, the nature of risk changes. The company stops selling just silicon and begins to bear credit exposure to a customer that is not yet profitable, with the option to become a shareholder if the notes are converted. If the IPO occurs within the discussed range, the conversion is likely to be advantageous. If the November window closes, Broadcom will have lent billions to its largest future customer precisely when the market is repricing the sector.
