AI Agent UpdateWall Street lines up $63B to finance Broadcom chips for Anthropic — with Broadcom itself backstopping the senior debt
Banks and Blackstone will fund a vehicle that buys Broadcom AI chips and leases them to Anthropic — a deal that proves debt markets are still open for AI, and shows exactly what it costs to keep them open.
The News
Wall Street has found a new way to finance the AI buildout: lend to a middleman. Bank of America, Citi and Morgan Stanley are arranging about $43.5 billion of first-lien financing — the senior loans that get paid back first if anything goes wrong, equal to about 69% of the total — and Blackstone is the sole provider of the committed second-lien portion, in a $63 billion package to fund a special-purpose vehicle. A special-purpose vehicle, or SPV, is a separate company created for one job; here, that job is buying Broadcom XPU accelerators and networking gear and leasing them to Anthropic, with deliveries starting in 2027.
The catch is who stands behind the senior debt. Broadcom is providing residual-value support equal to the first-lien amount — in plain terms, if the leased chips are worth less than expected at the end of the deal, Broadcom covers the gap up to the size of the senior loans. Reuters describes this as effectively a significant guarantee. Broadcom CEO Hock Tan said the deal 'validates that there is capital available to finance such growth.' The Wall Street Journal's account added that banks wavered before weekend talks settled the deal on higher rates — lenders wanted to be paid more for the risk.
Broadcom shares rose 4.00% to $342.33 in the October 27 session as the details landed. The deal is one of the largest debt packages yet tied directly to AI compute, and it arrives hours after Anthropic's IPO filing laid bare the scale of its spending commitments. One figure to keep separate: Anthropic's S-1 reportedly carries about $161.2 billion of Broadcom leases over five years, but neither the filing nor the financing announcement confirms the new SPV is the same arrangement, so the two numbers should not be merged.
When the chipmaker has to guarantee the loan for its own chips, the demand is real — and so is the risk.
Why It Matters
This deal matters because it answers the question hanging over the whole AI trade: who pays, and on what terms? Until now, most AI infrastructure was funded by the hyperscalers' own cash or their bonds. A $63 billion third-party financing, assembled by the biggest banks and the biggest private-credit name, says debt markets will still fund AI compute at scale — but only with the chipmaker itself absorbing the downside on the senior loans. That is a meaningful shift in who bears the risk.
For Broadcom, the structure is both a vote of confidence and a contingent liability. If Anthropic thrives and the chips hold their value, Broadcom sells a mountain of accelerators with someone else's money. If demand falters or chip values fall faster than expected, Broadcom's guarantee is what stands between lenders and losses. Investors should read the guarantee, not just the headline number, when judging how much of this $63 billion is really new demand versus demand pulled forward by generous financing.
For the rest of the market, the deal is a template. If this structure works, expect more SPVs, more chip leases, and more guarantees — and expect the debate about AI debt, which flared after SpaceX's $40 billion GPU-debt warning on October 26, to focus less on whether the money exists and more on whose balance sheet it ultimately sits on.
Analyst's Take
The bull case is real: $63 billion of private capital, arranged in days, for one customer's chip supply is demand validation at a scale the industry has never seen. The bear case is equally real: the deal only cleared because Broadcom backstopped the senior debt and lenders extracted higher rates. Both things are true at once, which is why the verdict is Mixed rather than Bullish.
Watch two things next: whether Anthropic's IPO roadshow, expected the week of November 9, prices this financing as strength or as a warning, and whether copycat SPV deals follow with looser or tighter guarantees. The guarantee terms on the next deal will tell you more than the size of this one.
By The Numbers
FAQ
What is a special-purpose vehicle?
A separate company set up for one specific job — here, owning chips and leasing them out. It keeps the debt off Anthropic's and Broadcom's main balance sheets, but as this deal shows, the risk can still find its way back through guarantees.
What is first-lien vs second-lien debt?
First-lien lenders get paid first if the borrower defaults; second-lien lenders get paid after them, so they take more risk and usually charge more. Here the banks hold the safer first-lien slice and Blackstone the riskier second-lien slice.
Why is Broadcom's guarantee important?
Because it means Broadcom, not just Anthropic, is on the hook if the leased chips lose value. The guarantee is part of why $43.5 billion of senior debt could be funded at this size — which tells you how lenders price the risk of AI hardware.
Is this the same as the $161.2 billion in Anthropic's IPO filing?
Not confirmed. The filing reportedly lists about $161.2 billion of Broadcom leases over five years, but neither the filing nor the financing announcement says the new $63 billion SPV is that arrangement. Treat them as separate figures.
Why is this running a day late?
The deal was announced on the evening of October 26 and confirmed in detail by wire coverage on October 27. It was never published here, so it runs today as a catch-up, with the timing disclosed.
