Broadcom has agreed to lend Anthropic up to $42 billion for infrastructure spending, a sum that could finance about a third of the AI lab’s $125.2 billion five-year computing lease, Reuters reported on 1 October, citing Anthropic’s IPO prospectus.
Key points
- The convertible debt could become Anthropic shares, and Broadcom could appoint a financing partner.
- Anthropic is expected to become Broadcom’s largest compute customer in 2027.
- Anthropic warned that payment or performance defaults could accelerate a substantial portion of its lease obligations.
Broadcom’s $42 billion convertible financing
The arrangement puts Broadcom on both sides of Anthropic’s infrastructure spending. Broadcom supplies hardware and has agreed to provide financing for the buildout. Its relationship with the AI lab also spans equipment leasing. Amazon, another major Anthropic partner, primarily supplies cloud infrastructure and distributes its Claude model.
Broadcom could designate another party to provide the financing. The debt instruments could be converted into Anthropic shares. Anthropic said in the prospectus that it does not expect any notes to be sold before its IPO is complete. The proposed offering could value the company at $2 trillion.
Anthropic deposited cash into a restricted account for Broadcom’s benefit in April 2026 in connection with the convertible debt. The company said it might have to add to that account in certain circumstances. That cash sits alongside a borrowing arrangement tied to the computing capacity Anthropic has committed to lease.
Anthropic has separately sought 50.1% founder voting control ahead of its planned IPO, AI Affairs previously reported. Under the Broadcom arrangement, conversion of the debt would give its holders Anthropic shares rather than leave the entire financing as debt.
Anthropic’s $125.2 billion TPU lease
The $125.2 billion commitment is for a five-year lease of tensor processing unit, or TPU, computing capacity. The convertible note Anthropic would issue could finance about a third of that commitment. Broadcom and Alphabet’s Google have worked together on several generations of TPUs.
Anthropic announced in April an expanded partnership with Broadcom and Google for access to multiple gigawatts of next-generation TPU computing capacity beginning in 2027. The lease commitment puts a cost alongside that planned access. Anthropic’s spending obligation runs for five years, while its access to the additional capacity is due to begin in 2027.
Anthropic’s prospectus warns that Broadcom’s position as both a hardware supplier and financing partner creates “potential conflicts of interest”, Reuters reported. Anthropic said Broadcom’s decisions on hardware and pricing could affect its ability to obtain enough computing infrastructure for its work.
Anthropic cautioned that some failures to pay or meet contractual requirements could bring much of its lease debt due immediately. Under those circumstances, its ability to use the $42 billion financing facility to meet those payments could be limited. The lease commitment therefore carries an obligation that could come due before its scheduled term ends.
Broadcom projects $115 billion in 2027 AI chip revenue
Anthropic is expected to become Broadcom’s largest compute customer in 2027. Its financing arrangement gives the chipmaker a role in funding the infrastructure behind that demand, as well as supplying hardware for it. Broadcom’s projected AI semiconductor revenue is about $115 billion in fiscal 2027.
Reuters compared the arrangement with rival Nvidia’s use of its balance sheet to support chip sales in recent years. Jay Goldberg, an analyst at Seaport Research, said Nvidia was committing substantial financial resources and Broadcom was following it. Robert Leitao, managing partner of Rothschild & Co., described the financing as a concentrated bet on the companies’ ability to generate enough revenue to support it.
Broadcom projects AI semiconductor revenue of $230 billion in fiscal 2028.
