IMPLICATOR
Broadcom has agreed to lend Anthropic up to $42 billion through convertible notes, Anthropic's IPO prospectus obtained by Reuters shows. The notes could convert into Anthropic shares, with proceeds restricted to its TPU computing-capacity lease obligations for chips Broadcom co-develops with Google. Broadcom President and CEO Hock Tan said on Broadcom's Sept. 2, 2026 earnings call that Anthropic is on track to become its largest XPU customer in 2027.
No notes had been issued as of Aug. 2, 2026. Anthropic said it does not expect any to be sold before it completes its IPO, which could value it at $2 trillion.
What Changed
- Broadcom agreed to lend Anthropic up to $42 billion through convertible notes that could convert into Anthropic shares, with proceeds restricted to its TPU lease obligations.
- The facility could cover about a third of Anthropic's $125.2 billion, five-year TPU lease commitment. No notes had been issued as of Aug. 2, 2026.
- Anthropic's prospectus says Broadcom's role as both hardware supplier and financing partner creates "potential conflicts of interest."
- Separately, Broadcom puts its maximum potential liability under a lease backstop at about $29 billion, and its banks are gathering a $60 billion AI chip financing package.

Filing terms
Neither the reported prospectus terms nor Broadcom's filing includes an interest rate or a conversion price for the notes.
Broadcom's Form 10-Q filed Sept. 10, 2026 describes the facility without naming the customer. It says the customer may issue notes "under certain circumstances and if needed," solely for lease obligations.
The facility could cover about a third of Anthropic's $125.2 billion, five-year commitment to lease TPU computing capacity. Anthropic deposited cash in a restricted account for Broadcom's benefit in April 2026 and may have to add more in certain circumstances.
Certain payment or performance defaults could make a substantial portion of Anthropic's lease obligations due at once. They could also limit its ability to draw on the $42 billion facility to cover those payments.

Supplier and lender
Anthropic's prospectus says Broadcom's role as hardware supplier and financing partner creates "potential conflicts of interest" that could affect access to computing power.
On that call, CFO Amie Thuener said the company partners through the AI XPV platform with third-party financial partners "to independently underwrite and capitalize the assets rather than providing the direct financing ourselves."
The 10-Q says the customer would issue the convertible notes to Broadcom. Anthropic's prospectus says Broadcom may designate a financing partner for the notes.
Lease backstop
Broadcom launched that platform with Apollo and Blackstone in June 2026. Its first $35 billion tranche financed Anthropic's deployment of more than 1 gigawatt of computing infrastructure.
Broadcom's September filing puts its maximum potential liability under the separate lease backstop at about $29 billion once all racks are deployed, with no amounts paid under that backstop.

In a lease default, Broadcom's liability equals the difference between 85% of outstanding amounts owed under the backstop and the racks' sale value. The filing lists the backstop and note facility separately and gives no combined exposure figure.
Financing competition
"It feels that there's quite a concentrated bet right now on two companies being able to generate enough revenues to support all the financing that's happened," said Robert Leitao, managing partner of Rothschild & Co.
"Nvidia is putting in place a massive amount of its balance sheet, and Broadcom is having to follow suit," Seaport Research analyst Jay Goldberg said. In August 2026, Nvidia announced a partnership with six finance firms, including Blackstone, to mobilize more than $500 billion for AI, including helping customers fund chip purchases.
Bank financing package
Broadcom's banks are starting to gather $60 billion of AI chip financing for Anthropic and other companies, Bloomberg reported, citing people with knowledge of the matter. The unannounced package has a $42 billion Class A senior-secured tranche, backed by collateral and repaid first. Its $18 billion Class B junior tranche, repaid after senior debt, is led by Blackstone, which is committing $9 billion. The reports do not link that senior tranche to the $42 billion convertible-note facility.
Tan said on the same call: "It's an open secret, Anthropic is well on its way to an IPO, and with that, its investment credit will change."
Frequently Asked Questions
How much is Broadcom lending Anthropic?
Up to $42 billion through convertible notes, according to Anthropic's IPO prospectus. The proceeds can be used only for Anthropic's TPU lease obligations, and the notes could convert into Anthropic shares. No notes had been issued as of Aug. 2, 2026.
What would the loan pay for?
It could cover about a third of Anthropic's $125.2 billion, five-year commitment to lease TPU computing capacity. Broadcom co-develops those chips with Google.
Why does Anthropic flag a conflict of interest?
Its prospectus says Broadcom's role as both hardware supplier and financing partner creates "potential conflicts of interest" that could affect Anthropic's access to computing power.
Is the $42 billion loan the same as the $42 billion bank tranche?
No source links them. Broadcom's banks are gathering a $60 billion AI chip financing package with a $42 billion senior-secured tranche and an $18 billion junior tranche led by Blackstone. The reports do not connect that tranche to the convertible-note facility.
What happens if Anthropic defaults on its leases?
Certain payment or performance defaults could make a substantial portion of its lease obligations due at once and limit its ability to draw on the $42 billion facility. Separately, Broadcom's 10-Q puts its maximum potential liability under a lease backstop at about $29 billion once all racks are deployed.
