Broadcom has agreed to lend Anthropic up to $42 billion to help finance the AI company's massive chip leasing commitments, according to details from Anthropic's draft IPO prospectus first reported by Reuters on October 1. The arrangement makes Broadcom simultaneously Anthropic's chip supplier, equipment lessor and lender, and it offers one of the clearest views yet of how the AI industry is financing its unprecedented infrastructure buildout.
The disclosure comes as Anthropic prepares for a public listing that could value the company at around $2 trillion, more than double its reported $965 billion valuation from May.
How the Deal Works
According to the reporting, the financing is structured as a convertible note facility:
- Broadcom will lend Anthropic up to $42 billion.
- The money could cover roughly a third of the $125.2 billion Anthropic has committed to a five-year lease of tensor processing unit (TPU) computing capacity.
- Broadcom may bring in a financing partner, and the notes could eventually convert into Anthropic equity.
- Anthropic says it does not expect any notes to be sold before its IPO.
The filing also shows that in April 2026, Anthropic placed funds into a restricted account held for Broadcom's benefit and may need to add more depending on circumstances. That same month, Anthropic said it had expanded its arrangement with Broadcom and Google to access next-generation TPU compute beginning in 2027.
Broadcom's Growing Stake in Anthropic
For Broadcom, which designs Google's TPUs, the deal cements Anthropic's role as a cornerstone customer. Anthropic is expected to become Broadcom's largest compute customer in 2027, and Broadcom has projected AI chip revenue of about $115 billion in fiscal 2027 and $230 billion in fiscal 2028.
Lending to a customer so it can buy your products is not new in AI. Nvidia has used its balance sheet in recent years to support customers and partners that in turn purchase its hardware. Critics on Wall Street have labelled such arrangements circular financing, warning that they can inflate demand signals across the sector.
Risks Flagged in the Prospectus
Anthropic's draft filing is candid about the potential downsides:
- Conflicts of interest: Broadcom acting as both hardware supplier and lender creates potential conflicts that could affect Anthropic's access to compute.
- Acceleration risk: Certain payment or performance defaults could make a large part of Anthropic's lease obligations due immediately, while also limiting its ability to draw on the $42 billion facility.
- Massive commitments: Anthropic expects to spend at least $518 billion on AI infrastructure over the next decade across partners including Google, Amazon, Microsoft and Broadcom, with about 80% of that reportedly non-cancellable or payable regardless of usage.
Earlier reporting on the leaked draft showed Anthropic's 2025 recognised revenue reached $4.59 billion, roughly twelve times its 2024 level, and that the company reported operating profits in recent quarters. Anthropic has not publicly confirmed the draft, and no public S-1 has been filed.
Why It Matters
The Broadcom facility highlights the central business challenge of frontier AI: compute costs are enormous, long-term and largely fixed, while revenue, though growing rapidly, depends on enterprise demand that can shift quickly. Locking in multi-year TPU capacity gives Anthropic the infrastructure it needs to train and serve models like its Claude family, but it also concentrates risk among a small group of suppliers and financiers.
For investors evaluating a potential Anthropic IPO, the deal adds a new layer of complexity. Convertible notes held by a key supplier could dilute future shareholders, and covenant-style default triggers could tighten the company's flexibility if growth slows. For the broader market, the arrangement is another data point in the debate over whether AI infrastructure spending is sustainable or being propped up by interlocking deals among a handful of giants.
Key numbers at a glance
- $42 billion: maximum Broadcom loan facility.
- $125.2 billion: five-year TPU lease commitment.
- $518 billion: Anthropic's expected decade-long infrastructure spend.
- About $2 trillion: reported IPO valuation target.
What Comes Next
Anthropic's IPO timing remains fluid, with reports suggesting a listing could come after the U.S. midterm elections in November. Until a public filing appears, details remain drawn from the confidential draft. What is already clear is that the race to build frontier AI is now as much a contest of financial engineering as of machine learning, and chipmakers like Broadcom are positioning themselves at the centre of both.
