AI hyperscaler bond issuance surges nearly 1,000%, hidden off-balance-sheet debt hits $1.65T

AI's debt binge can't last, hidden borrowing reaches $1.65T

S&P Global reports hyperscalers and Nvidia issued $225B in bonds in H1 2026, a 973.7% jump, putting them on track for $400B this year. Yield premiums are already rising as markets digest the flood. Nikkei found off-balance-sheet debt at the five largest U.S. tech firms has grown 8x in four years to $1.65T, driven by long-term GPU and data-center lease commitments. That debt sits in footnotes, not on the balance sheet. RSM's chief economist warns federal deficits will eventually force lenders to charge higher premiums across public and private borrowers.

Why it matters: Fortune and Nikkei surface the other side of the AI capex ledger: $225B in H1 bond issuance and $1.65T in off-balance-sheet obligations, with markets already demanding higher spreads. Hits all three HKR axes. Score capped at 82 rather than 85+ because this is financial analysi...

The reason to click: two numbers that look worse together. S&P Global says hyperscalers and Nvidia issued $225 billion in bonds in the first half of 2026, a 973.7% jump from last year. Separately, Nikkei found the five largest U.S. tech firms have $1.65 trillion in off-balance-sheet commitments—mostly long-term GPU and data-center leases—up 8x in four years. That debt lives in footnotes, not on the balance sheet.

S&P warns markets are already pushing back: yield premiums on these bonds are rising. RSM's chief economist adds that a nearly $2 trillion federal deficit means the government is competing for the same bond buyers, which will eventually force lenders to charge more across the board.

I'd discount this a bit—it's a weekend roundup citing S&P and Nikkei secondhand, no links to the original reports. But the direction is right. If borrowing costs keep climbing, hyperscalers either cut capex or pay more for capital. Either way, that pressure eventually shows up in compute pricing.
