Big Tech uses guarantees to keep ~$300bn of AI exposure off the books

A Financial Times investigation finds Meta, Nvidia, Broadcom, Alphabet and peers have piled roughly $300 billion of AI infrastructure exposure into structures where special-purpose vehicles hold the debt while tech companies backstop residual value — so most of it never shows as ordinary balance-sheet debt.

FINANCE desk — The AI boom’s real leverage may not sit on the lines investors skim first. If demand for GPUs and data halls softens, residual-value guarantees can pull hundreds of billions of contingent risk back onto Meta, Nvidia, Broadcom, Alphabet and peers — the same names driving the equity story. Off-balance-sheet is not off-risk.

A residual-value guarantee, in plain English: lenders finance a data center or a chip fleet; the tech company promises to cover part of any shortfall if the asset later sells for less than an agreed floor. The debt sits mainly with a special-purpose vehicle — an SPV, a legal shell set up to hold that project — so most of the exposure does not show as ordinary balance-sheet debt at the tech company. File that mechanism as the FT’s. This desk did not underwrite a deal.

Alphabet: FT-attributed digests say data-center lease guarantees rose from about $16.9 billion to $43.8 billion in six months, with under 2% of that booked as balance-sheet debt. File those $16.9 billion / $43.8 billion / under-2% lines as the FT’s, via those digests. Do not invent a rounded “about $17 billion” or a different share. This desk did not open Alphabet’s footnotes.

Meta’s Louisiana Hyperion project, still FT-attributed: structured through a Delaware SPV named Beignet Investor (Blue Owl about 80%, Meta about 20%), with roughly $28 billion of residual-value guarantees supporting about $27 billion of project debt involving large asset managers — Pimco, BlackRock, and Apollo are named in FT-attributed digests. File that SPV / ownership / $28 billion / $27 billion picture as the FT’s. This desk did not sit on the Louisiana close.

Broadcom: about $29 billion of exposure around chip financing tied to Anthropic, per the FT as those same digests carry it. File the $29 billion / Anthropic-chip line as FT-attributed. This desk did not see a Broadcom term sheet.

Nvidia: about $105 billion in guarantees connected to a SoftBank data-center development for OpenAI, again FT-attributed. File that $105 billion / SoftBank / OpenAI line as the FT’s. This desk did not audit a SoftBank vehicle.

Oracle and Amazon are cited using variants of the same guarantee / SPV pattern. Name them as the FT does. Do not invent extra deals, dollar figures, or project names for either company.

What this card is not: a finding that any company has defaulted, that the $300 billion is “hidden illegally,” or that rating agencies have downgraded anyone on this investigation alone. The FT frames contingent credit exposure and accounting presentation — promises that can become losses if asset values fall — not a fraud finding. File that frame. This desk is not calling the structure illegal.

Do not conflate this card with the separate 18 Sep 2026 Financial Times story on OpenAI’s cash burn and investor presentation. That is an older, different primary about OpenAI’s own cash use. This filing is Big Tech residual-value guarantees and SPVs only.

Plain English for the rest of the card: residual-value guarantee = a promise to cover part of the gap if a data center or chip fleet later sells below an agreed floor. SPV / special-purpose vehicle = a legal shell that holds the project debt, so most of it is not ordinary debt on the tech company’s books. off-balance-sheet = not listed as regular debt on the headline financial statements investors skim first. contingent exposure = a risk that becomes a bill only if a trigger hits — here, if the asset is worth less than the guaranteed floor. Hyperion = Meta’s Louisiana data-center project named by the FT. Beignet Investor = the Delaware SPV in that structure. This filing is the FT investigation plus attributed digests — not a default, not a fraud finding, and not a new accounting rule.

REPORTED here: the Financial Times’ 20 Sep 2026 investigation — Tier B originating newsroom, not a company newsroom PRIMARY. AI Weekly and Coinpaper are same-day digests attributing that FT investigation — used only to corroborate attribution, not as a second originating newsroom and not as a license to invent figures beyond the FT. The about-$300 billion off-balance-sheet picture, residual-value guarantees, SPVs holding the debt, Alphabet’s $16.9 billion to $43.8 billion lease-guarantee jump with under 2% booked as debt, Meta’s Hyperion / Beignet Investor / Blue Owl ~80% / Meta ~20% / ~$28 billion guarantees / ~$27 billion project debt / Pimco–BlackRock–Apollo picture, Broadcom’s about-$29 billion Anthropic-chip exposure, Nvidia’s about-$105 billion SoftBank / OpenAI guarantees, and Oracle / Amazon as named variants are FT-attributed. NOT claimed: that any named company defaulted, that the $300 billion is hidden illegally, that rating agencies downgraded anyone on this investigation alone, a fraud finding, that this desk saw the deal documents, a stock tip, or investment advice. Distinct from the already-filed draftkings-ai-target-losers, faraday-future-eai-919, bis-ai-market-vulnerability, and crusoe-3-9b-series-f. Distinct from the separate 18 Sep 2026 FT OpenAI cash-burn / investor-presentation story.
