Broadcom is raising more than $60 billion in debt to finance AI chip deployment for Anthropic and other hyperscalers.
The company's AI semiconductor business is on pace to hit more than $100 billion in revenue by 2027, but the leverage structure poses risk if hyperscaler spending cools.
A rival chip deal with Broadcom's largest customer has already spooked investors.
What happened
On August 20, Broadcom was reported to be negotiating more than $60 billion in fresh debt, with the deal potentially swelling to as much as $100 billion once every piece is counted. The borrowing funds an AI chip financing arrangement that benefits Anthropic and other customers.
Why it matters
Broadcom's custom AI chips have become the preferred alternative to general-purpose GPUs for hyperscalers running large, predictable workloads. The company's AI semiconductor revenue reached $10.8 billion in the second quarter and management has said it has line of sight to more than $100 billion in AI chip revenue alone by 2027—dwarfing the company's $64 billion in total revenue for 2025. The debt traces back to a June agreement with Apollo Global Management and Blackstone to fund a $35 billion expansion of Anthropic's computing capacity, part of a partnership meant to enable more than 20 gigawatts of AI compute by 2028.
What to watch
The financing structure carries real leverage risk: Broadcom is guaranteeing part of a senior secured tranche that could run $60 billion to $70 billion, on top of a roughly $30 billion junior tranche. Shares fell as much as 5.9% on August 19 after Marvell Technology disclosed a new custom chip agreement with Alphabet, Broadcom's largest customer, covering AI inference accelerators and storage controllers—a sign the relationship may be diversifying despite the April TPU agreement remaining in place.

Broadcom has positioned itself as central to hyperscaler AI infrastructure through custom chips—application-specific integrated circuits—that are now the preferred alternative to general-purpose GPUs for large, predictable workloads. The company's April five-year deal with Alphabet covering Tensor Processing Unit generations and networking gear underscored that dominance. However, the scale of debt Broadcom is now raising reveals both the opportunity and the risk: the financing is tied directly to a $35 billion expansion of Anthropic's computing capacity negotiated in June with Apollo Global Management and Blackstone, aimed at delivering more than 20 gigawatts of AI compute by 2028. That kind of infrastructure investment requires sustained, elevated spending from a small number of hyperscalers—Alphabet, Amazon, and Microsoft—meaning Broadcom's growth thesis depends entirely on those companies maintaining their capex momentum. When Marvell Technology announced a new custom chip agreement with Alphabet in August, it signaled that even Broadcom's largest customer is beginning to diversify its supplier base, a move that sent Broadcom shares down 5.9% despite the April TPU deal remaining in place.
