Broadcom has agreed to lend Anthropic up to $42 billion to finance its lease of TPU chips, according to documents pulled from Anthropic’s IPO prospectus. The convertible note facility covers roughly one-third of the $125.2 billion commitment Anthropic has made to lease TPU computing capacity over five years, Reuters reported exclusively, citing the filing.
The deal is one of the clearest examples yet of vendors financing the buildout that their own chips power. Anthropic leases TPU capacity, Broadcom supplies the silicon, then lends Anthropic the money to pay for the leases. That loop has drawn scrutiny from investors who worry the circular financing behind AI infrastructure spending looks healthier on paper than it is in cash.
What the filing shows
The arrangement sits inside Anthropic’s broader $518 billion compute commitment, disclosed in the IPO prospectus first reviewed by Reuters and now widely reported. Roughly $111.1 billion is owed to Google between April 2026 and July 2033, $110 billion to Amazon between May 2026 and April 2036, and $31.4 billion to Microsoft between November 2026 and May 2033. Commitments tied to Broadcom-related equipment leases total about $161.2 billion, the largest single slice of the buildout.
| Partner | Commitment (minimum) | Window |
|---|---|---|
| Broadcom (equipment leases) | $161.2 billion | through the early 2030s |
| $111.1 billion | April 2026 to July 2033 | |
| Amazon | $110 billion | May 2026 to April 2036 |
| Microsoft | $31.4 billion | November 2026 to May 2033 |
| AMD | $20 billion+ in capacity | stock purchase up to $5 billion |
About 80% of the $518 billion total is non-cancelable or payable regardless of how much compute Anthropic actually uses, meaning the company carries fixed costs regardless of demand for Claude.
A financing chain that closed in the prospectus
Broadcom’s role in Anthropic’s infrastructure dates from April 2026, when Anthropic announced an expanded partnership with Broadcom and Google to access multiple gigawatts of next-generation TPU capacity starting in 2027. The new $42 billion lending facility, described in CNBC’s reporting as a convertible note Anthropic could issue to Broadcom, remains an option that could be drawn against if the company needs to cover lease payments. The note is structured so that Anthropic can choose when or whether to draw on it, depending on how its cash position evolves through the IPO.
Broadcom’s own involvement in AI infrastructure has grown quickly. The company saw revenue from custom AI accelerators and networking gear climb through 2026 as hyperscalers moved away from buying only general-purpose GPUs toward contracted TPU capacity. Lending to a customer at such scale is unusual; it puts Broadcom on the hook for Anthropic’s creditworthiness while also benefiting from the volume of chip leases the loan finances.
What it says about Anthropic’s cash burn
Anthropic reported a net loss of about $42 billion in 2025, though roughly $34 billion of that was a non-cash accounting charge tied to the rising value of financing instruments that could convert into shares. Operating losses excluding writedowns came in above $8 billion, and the company held $20.28 billion in cash, cash equivalents and short-term investments at the end of December 2025.
Revenue grew roughly twelvefold in 2025 to nearly $4.6 billion, a pace that puts the compute bill on a different order of magnitude. Even if revenue keeps compounding at a fraction of last year’s rate, the fixed costs of the leases mean Anthropic is betting on sustained enterprise adoption of Claude through the early 2030s. Notably, the prospectus analysis of the commitments shows that nearly a quarter of 2025 revenue came from just two customers, and many large customers are not locked into long-term contracts.
The IPO filing describes the Broadcom facility as one of several financing mechanisms tied to the compute buildout, alongside supplier credit arrangements with AMD and preferred stock components from Amazon and Google.
Read-through for the AI infrastructure trade
Vendor financing has a long history in semiconductors, usually showing up when demand outpaces buyers’ balance sheets. Broadcom has demanded upfront and contractual commitments from Anthropic, and the new loan closes that loop by lending against the same leases it profits from. Investors scanning AI infrastructure credits will watch two numbers: how much of the $42 billion actually gets drawn, and how the lease obligations stack against Anthropic’s cash balance once public-market proceeds arrive. Neither number is disclosed today.
The IPO itself remains one of the largest technology listings ever attempted. Anthropic has filed confidentially to go public by November, at a valuation expected to top $2 trillion, more than double its own $965 billion private valuation from May. SpaceX’s recent listing, which valued Elon Musk’s company at $1.77 trillion, set the timing for a window that has been unusually receptive to large AI and space listings. Bankers including Goldman Sachs, JPMorgan and Morgan Stanley are reported to be involved in the deal, though Anthropic has not confirmed these names publicly.
For Broadcom, the deal locks in TPU demand through the early 2030s, when the Google-side payments wind down. For Anthropic, it converts a vendor relationship into a financing lifeline, narrowing the gap between what the company owes and what it can carry on its own balance sheet. The note also aligns Broadcom’s incentives with Anthropic’s survival rather than with Anthropic’s margins, a subtle shift that could matter if the compute bill starts to weigh on profitability.
Anthropic declined to comment on the Broadcom loan. Broadcom did not immediately respond to a request for comment. The facility’s structure and drawdown terms are laid out in the confidential filing and will be subject to normal IPO due diligence once the company publishes its registration statement in full.
