Anthropic details a broad, interlocking relationship with Broadcom that reaches from the chips powering its models to the money helping pay for them. According to the filing, Broadcom has agreed to provide up to $42 billion in loan financing for infrastructure. As part of that setup, Broadcom can choose a financing partner, and the notes issued under the arrangement could be converted into Anthropic equity.
The company also says it does not expect any notes to be sold until after it completes its initial public offering. In connection with the convertible notes, Anthropic states that in April 2026 it placed cash in a restricted account earmarked for Broadcom's benefit, with the possibility that additional amounts may need to be contributed under certain conditions.
While Amazon is listed among Anthropic's other significant partners and investors, its role is centered on cloud infrastructure and distribution for Claude. By contrast, Broadcom's involvement cuts across compute, leasing, and funding, giving the chipmaker an outsize place in Anthropic's buildout.
Anthropic says the convertible note it would issue could fund roughly one third of its $125.2 billion obligation for a five year lease of tensor processing unit compute capacity. Alphabet's Google and Broadcom have co developed several generations of TPUs, and in April Anthropic said it broadened its collaboration with both companies to secure access to multiple gigawatts of next generation TPU compute starting in 2027.
The company is expected to become Broadcom's biggest compute customer in 2027 and, next year, its largest buyer in Broadcom's core chip design business. Broadcom, meanwhile, projects roughly $115 billion in AI chip sales for fiscal 2027 and $230 billion for fiscal 2028.

As Anthropic heads toward a public offering that could value it at $2 trillion, its two way ties with Broadcom stand out as a prime example of the back and forth spending that has energized AI skeptics. "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," Robert Leitao, managing partner at Rothschild & Co., said. The strategy also mirrors a playbook seen elsewhere in chips. "Nvidia is putting in place a massive amount of its balance sheet, and Broadcom is having to follow suit," said Seaport Research analyst Jay Goldberg.
Anthropic flags the risks plainly. It says Broadcom's position as both hardware supplier and financing counterparty creates "potential conflicts of interest" that could influence access to the compute it needs. The company also warns that Broadcom's choices on pricing and product direction could affect its ability to line up enough infrastructure.
Certain payment or performance defaults, Anthropic adds, could accelerate a major slice of its lease obligations and at the same time constrain use of the $42 billion facility to cover those amounts. Broadcom declined to comment. Anthropic declined to comment.
For your money, the takeaway is straightforward: this is capital intensive, timing sensitive infrastructure spending, paired with financing that is deeply linked to a key supplier. If Anthropic executes, the spending flywheel could hum. If not, the obligations come due all the same.
