Broadcom’s relationship with Anthropic is starting to look less like a conventional supplier deal and more like a financing loop built around future AI demand.
Anthropic’s IPO prospectus shows Broadcom has agreed to make up to $42 billion of financing available for infrastructure spending, with the ability to designate a financing partner.
The facility could fund roughly a third of Anthropic’s $125.2 billion five-year commitment to lease TPU computing capacity.
At the same time, Anthropic is expected to become Broadcom’s largest custom-chip customer in 2027, tying the financing directly to the semiconductor company’s future revenue ambitions.
Why Broadcom wants to finance the buyer
The structure explains why Broadcom is willing to put so much capital around one customer.
Its AI semiconductor business is expanding far faster than the rest of the company, and management expects revenue from those chips to reach about $115 billion in fiscal 2027 and $230 billion in 2028.
Broadcom and Google have already agreed to support about 3.5 gigawatts of next-generation TPU capacity for Anthropic beginning in 2027.
In June, Broadcom also launched an AI infrastructure platform with Apollo and Blackstone, starting with a $35 billion financing tranche tied to more than 1 gigawatt of Anthropic compute.
Broadcom has said that outside financial partners are expected to underwrite and capitalise most of these assets rather than leaving the entire burden on its own balance sheet.
Still, the Anthropic filing shows how closely financing, equipment supply and future chip sales are becoming linked.
The circularity risk is real
That creates an obvious circularity risk. The supplier is helping create the financing that allows its customer to buy or lease more of the supplier’s technology.
If Anthropic keeps growing rapidly, the structure can accelerate Broadcom’s sales, but in case the economics disappoint, the same relationship could concentrate both credit and customer risk.
Anthropic itself flags potential conflicts of interest around Broadcom’s dual role as hardware supplier and financing partner.
The filing also warns that some defaults could accelerate lease obligations while limiting Anthropic’s ability to draw further on the financing facility.
Bank of America analysts have previously modelled Broadcom’s residual-value exposure on AI financing structures and concluded that losses could remain manageable under moderate default assumptions.
But the bank also highlighted how quickly exposure could rise if Broadcom scales the model across more customers.
JPMorgan analyst Harlan Sur recently argued that Broadcom’s long-term AI revenue guidance may still prove conservative if deployments and supply ramp faster than management currently assumes. That is the upside Broadcom is financing towards.
Anthropic’s IPO becomes a Broadcom test
The broader numbers show why the company is willing to take that risk. Broadcom says demand from its six major AI customers exceeds the supply it has secured, with roughly $350 billion of AI semiconductor revenue expected across fiscal 2027 and 2028.
For Broadcom, the $42 billion facility is therefore not simply a loan to Anthropic. It is a way of helping finance the 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.
