Broadcom's relationship with Anthropic is evolving into a financial arrangement that intertwines chip supply with future AI infrastructure spending. The AI company's IPO prospectus reveals that Broadcom has committed up to $42 billion in financing for infrastructure, potentially covering a third of Anthropic's $125.2 billion five-year lease commitment for TPU computing capacity.
This financing structure is not merely a loan but a strategic move to secure future demand for Broadcom's custom AI chips. Anthropic is projected to become Broadcom's largest custom-chip customer by 2027, directly linking the financing to Broadcom's ambitious revenue forecasts. Management expects AI chip revenue to reach approximately $115 billion in fiscal 2027 and $230 billion in 2028.
Why Broadcom is financing its own customer
The rationale behind this capital commitment lies in the rapid expansion of Broadcom's AI semiconductor business, which is outpacing the rest of the company. Broadcom and Google have already agreed to support about 3.5 gigawatts of next-generation TPU capacity for Anthropic starting in 2027. In June, Broadcom launched an AI infrastructure platform with Apollo and Blackstone, beginning with a $35 billion financing tranche tied to over 1 gigawatt of Anthropic compute.
Broadcom has indicated that external financial partners will underwrite most of these assets, reducing the burden on its own balance sheet. However, the Anthropic filing underscores how closely financing, equipment supply, and future chip sales are becoming interconnected.
The circularity risk is real
This arrangement introduces a circularity risk: the supplier is helping finance the customer's purchases of its own technology. If Anthropic grows rapidly, the structure could accelerate Broadcom's sales, but if economics disappoint, the relationship could concentrate both credit and customer risk. Anthropic itself flags potential conflicts of interest regarding Broadcom's dual role as hardware supplier and financing partner.
The filing also warns that certain defaults could accelerate lease obligations and limit Anthropic's ability to draw further on the facility. Bank of America analysts have modeled Broadcom's residual-value exposure and concluded that losses could remain manageable under moderate default assumptions, but they also highlighted how quickly exposure could rise if the model is scaled across more customers.
JPMorgan analyst Harlan Sur recently argued that Broadcom's long-term AI revenue guidance may prove conservative if deployments and supply ramp faster than management assumes. That is the upside Broadcom is financing towards.
Anthropic's IPO becomes a Broadcom test
The broader numbers show why Broadcom is willing to take this risk. The company says demand from its six major AI customers exceeds supply, with roughly $350 billion of AI semiconductor revenue expected across fiscal 2027 and 2028. For Broadcom, the $42 billion facility is not simply a loan but a way to finance infrastructure that could create one of its biggest future revenue streams.
The trade-off is concentration, as Broadcom is betting that Anthropic will grow quickly enough to service its commitments and keep buying compute at enormous scale.
