Analysis
Broadcom is negotiating with a group of lenders to raise more than $60 billion in debt -- and potentially $70 billion to $100 billion across the full structure -- to finance a special-purpose vehicle that will buy Broadcom's custom AI chips and lease them to Anthropic, [24/7 Wall St. reported](https://247wallst.com/investing/2026/08/24/broadcoms-60-billion-ai-debt-deal-hides-a-370-billion-question-nobody-on-wall-street-wants-to-answer/) on August 24, with the figures corroborated by Yahoo Finance and earlier framing from CNBC. The structure pairs a roughly $30 billion junior tranche with a $60-70 billion senior-secured tranche that Broadcom partially guarantees -- Anthropic doesn't buy the hardware directly, the SPV's investors finance the purchase and lease the compute capacity to Anthropic instead.
Pulse first reported this financing push on August 20, when the talks were described as up to $100 billion covering custom chip production for both Anthropic and OpenAI, with Anthropic alone expected to account for more than 40% of the volume. What's changed in the four days since: this week's reporting narrows the structure specifically around Anthropic and ties it explicitly to the AI XPV partnership Broadcom struck with Apollo and Blackstone in June -- whose opening deal raised $35 billion to expand Anthropic's compute using Broadcom's custom chips and networking gear. The lease mechanics (SPV buys, Anthropic leases) and Broadcom's partial guarantee on the senior tranche are new specifics that weren't part of the earlier reporting.
- Broadcom -- chip designer providing custom AI silicon and networking equipment, guaranteeing part of the senior-secured debt tranche
- Apollo Global Management, Blackstone -- financial sponsors behind the original June AI XPV partnership and its $35 billion opening deal
- Anthropic -- the compute customer leasing chip capacity through the SPV rather than purchasing chips outright
- Bank of America -- estimating total exposure across the structure could reach roughly $370 billion by 2029
“The lease mechanics (SPV buys, Anthropic leases) and Broadcom's partial guarantee on the senior tranche are new specifics that weren't part of the earlier reporting.”
The AI XPV partnership's stated goal is financing more than 20 gigawatts of AI compute by 2028, and Bank of America's $370 billion 2029 exposure estimate is the largest figure attached to this deal so far -- larger than the up-to-$100 billion ceiling floated in Pulse's original August 20 coverage, reflecting how quickly the projected scale of this financing structure has grown as more of it gets reported.
The competitive backdrop matters here too: Nvidia remains the dominant AI chip supplier by far, but Broadcom's custom ASIC business -- designing chips to a customer's specific workload rather than selling general-purpose GPUs -- has become the primary alternative path for hyperscalers and frontier labs wanting to diversify away from single-vendor dependence on Nvidia. Anthropic using Broadcom-designed chips financed through a dedicated SPV, rather than buying Nvidia GPUs directly, is itself a data point in that diversification trend, alongside Anthropic's own reported effort to build an in-house chip team.
The Counterweight
The counterweight worth stating plainly: none of the reporting on this deal -- not this week's, not the August 20 version -- has disclosed a closing date, final lender commitments, or confirmation the deal has actually been signed. "In talks to raise" is meaningfully different from "has raised," and Bank of America's $370 billion figure is a forward-looking exposure estimate for 2029, not a number tied to any signed commitment today. SPV structures also concentrate credit risk with lenders and bondholders rather than eliminating it -- if Anthropic's revenue growth decelerates from its current trajectory, the debt still has to be serviced by whoever holds the lease payments.
Broadcom's next earnings call is the concrete test: whether the company discloses exactly how much of its own balance sheet backs the senior tranche's guarantee, or continues describing the structure only in the aggregate terms disclosed so far.
