Broadcom to lend Anthropic $42bn for chip leases, becoming largest customer
Broadcom has agreed to lend Anthropic up to $42 billion in convertible notes to finance infrastructure spending, according to Anthropic's prospectus filed this week. The facility would cover roughly one-third of the $125.2 billion Anthropic has committed to spend over five years on tensor processing unit computing capacity. Broadcom's role spans three functions: hardware supplier, equipment lessor, and now lender, a concentration that the prospectus flags as creating "potential conflicts of interest" that could compromise Anthropic's access to computing power or its ability to tap the financing if payment or performance defaults occur. The convertible notes could be converted into Anthropic , and Broadcom retains the to bring in a financing partner. Anthropic does not expect to sell any notes before completing its IPO. In April 2026, Anthropic placed cash into a restricted account for Broadcom's benefit and may be required to add further amounts under certain conditions. Anthropic is projected to become Broadcom's largest chip design customer in 2027, when Broadcom expects of approximately $115 billion. The arrangement mirrors a strategy Nvidia has deployed in recent years, using balance-sheet strength to drive chip demand. Broadcom's three-pronged involvement distinguishes it from other major Anthropic partners like Amazon, whose role is concentrated in cloud services and distribution. The prospectus also disclosed that Anthropic routed 47 percent of its 2025 sales through Amazon and Google's cloud marketplaces, paying roughly $351 million in distribution fees. Anthropic's revenue surged 12-fold to nearly $4.6 billion in 2025, while operating losses more than doubled to exceed $8 billion. The company is seeking a of more than $2 trillion for the offering.
