Big Tech's Hidden AI Debt Hit $1.65 Trillion. It's Completely Legal.
Meta's newest data center, Hyperion, sits inside a joint venture with Blue Owl Capital that carries $27 billion in debt. Meta is the sole tenant, yet none of that $27 billion appears on Meta's own balance sheet.
A Nikkei investigation puts five US tech giants' off-balance-sheet AI debt at $1.65 trillion, an eightfold jump in four years that now tops the $1.35 trillion they report outright, mostly through data-center leases and GPU deals that never touch a debt line.
On HN, the fight moved past the number to who eats the loss if AI demand disappoints: one reply blamed the banks; a sharper reply said the real exposure sits with private credit funds most readers have never heard of.
What "hidden" means: a $27 billion data center with one tenant
Nikkei's investigation tracked five companies' AI infrastructure spending over four years and found $1.65 trillion in liabilities that never register as debt in their filings: money owed for data centers and GPUs that behaves exactly like debt but gets booked as an operating lease instead.
That $27 billion Hyperion joint venture is the template for the whole $1.65 trillion figure. A lease only forces its way onto a tenant's balance sheet if the tenant is contractually on the hook for finding a replacement should it ever walk away. Meta isn't on that hook, so under current accounting rules the debt legally belongs to the venture, not to the company that will be its only occupant. Repeat that structure across five companies and four years, and the total accumulates in footnotes instead of headline debt figures.
Oracle's thirtyfold bet, and the line that isn't quite Enron
Oracle pushed the model furthest: its off-balance-sheet debt grew roughly thirtyfold in four years, to $260 billion in future lease commitments plus $119 billion in purchase obligations tied to Nvidia hardware. S&P cut Oracle's credit rating over the resulting leverage; Morgan Stanley and Moody's flagged the same structural risk across the wider sector. Accounting consultant Tom Selling asked the plain version of the question: is a company "propping itself up with this accounting treatment"?
None of it is illegal, and analyst Gil Luria drew the comparison precisely enough that the HN thread would later reach for it too: "Enron's crime wasn't having special purpose vehicles. Enron's crime was hiding them." Disclosure rules tightened after Enron collapsed, so these vehicles now show up in footnotes and filings rather than nowhere at all: legal, disclosed, and still invisible to anyone who only reads the top-line balance sheet.
HN's argument: whose money actually disappears
The thread picked up exactly where Luria's line left off: not whether the debt is real, but who is left holding it once a data center's only tenant is the company that built it.
"Well technically they don't own the debt, the SPVs that own the data centers do. The giants just have long term commitments, but if shit hits the fan, it's not the tech giants but the banks that lent the money to the SPVs that are at risk. This usually means all of us are on the hook." — a commenter with over 13,000 karma
A reply corrected the mechanism with more precision:
"The banks are not the ones on the hook here - they no longer lend in a meaningful way as first loss lender on many things. If they lend they do so as a senior financing provider to vehicles that provide the financing. The actual lending is done by private credit institutions that have raised money, sometimes on the order of 10s of billions of $." — a commenter with roughly 450 karma
That correction changes who should be watching: not federally insured banks under a regulator's microscope, but funds that don't carry the same disclosure requirements.
Not every reply took the SPV structure at face value. One skeptic did the arithmetic on the other side of the transaction:
"…these companies are essentially paying for the service of taking the debt off books (by paying the leasing premium to the SPV partners). I guess I'm wondering what they really gain from doing so, if again sophisticated investors can see through the games?" — a commenter with 2,400+ karma
The 2008 comparison shows up anyway
The historical parallel arrived unprompted:
"The 5 horse men of the AIpocalypse. But this reminds me of 2008. Because when it goes all wrong, the US government is just going to bail them out just like they did with the banks to just keep the scam going. Because after all, they will be treated as 'too big to fail'." — a commenter with nearly 10,000 karma
Nobody in the thread disputed the mechanics; the disagreement was only about whether legality makes the outcome any less familiar.
The debt didn't vanish, it just changed who has to explain it
The number worth watching isn't $1.65 trillion itself, it's where the next revision of it will surface. Post-2008 reform turned bank balance sheets into the most audited instrument in finance, so this round of leverage grew up in the one corner regulators don't examine the same way: fund structures that raise money from pensions and insurers without deposit insurance or a central bank backstop. If Nikkei's number holds, an AI downturn won't announce itself with a bank run. It will just print, years from now, as a line item nobody outside the fund ever saw coming.

A copyright fight over Anne Frank's diary just made EU geo-blocking VPN-proof
Anne Frank's diary is public domain in Belgium but stays copyrighted in the Netherlands until 2037. When Dutch and Belgian scholars published a free scholarly edition online and geo-blocked Dutch readers, the copyright-holding Anne Frank Fonds sued anyway — arguing that any reader who slipped past the block with a VPN proved the whole site was illegal. The EU's top court just disagreed.
