AI Debt Binge Rattles Tech Bonds as Default Risk Premiums Surge for Broadcom and Oracle
nashnova research
Tech giants have issued nearly $500 billion in new debt this year to fund AI infrastructure, forcing the $10-trillion-plus U.S. corporate credit market to reprice risk — Oracle's five-year default probability now tops 20%, and Broadcom's CDS spread just hit a record high.
How much have they actually borrowed?
Oracle, Broadcom, and SpaceX have collectively issued close to $500 billion in new debt this year, almost entirely to build AI compute capacity.
Broadcom alone may need roughly $600 billion more over the coming years, per Bloomberg data. This means → today's record supply is the starting point, not the peak.
The U.S. investment-grade market has already seen nine deals above $25 billion this year — a record — with most coming from tech.
How high has the market priced default risk?
Credit-default swap (CDS) prices — essentially insurance against a borrower failing to pay — have surged: Oracle's five-year default probability tops 20%, SpaceX's sits around 16%, and even Nvidia is priced above 7%.
Broadcom's five-year CDS widened 3 basis points Thursday to 136 bps, a record. In plain terms = the market now charges Broadcom $1.36 in "insurance premium" for every $100 it borrows — the highest ever.
This reflects not a fear of imminent collapse, but a concern that so much debt is arriving so fast that concentration risk is climbing sharply.
What are investors really worried about?
T. Rowe Price portfolio manager Steven Kohlenstein warns: exposure is heavily concentrated in a handful of companies and a single AI investment cycle — even when spread across different issuers and structures, the correlated risk may not yet be fully priced.
In plain terms = the money goes to different names via different vehicles, but the underlying bet is the same — that AI delivers returns. If the AI cycle cools, these debts come under pressure together.
The core issue today is not deteriorating credit quality — most of these borrowers have solid earnings and steady cash flow. The pressure comes from supply: too much debt, too fast, giving investors the leverage to demand wider spreads.
Are more deals still lining up?
Broadcom just closed a $60 billion debt financing to fund Anthropic and is already planning the next mega-deal.
SpaceX is reportedly in talks to borrow $40 billion specifically to buy Nvidia chips.
Oracle is negotiating with Apollo and Goldman Sachs on a special structure: outside investors would set up an SPV — a special-purpose vehicle, a standalone legal entity created for a single transaction — to buy chips and lease them back to Oracle, sidestepping a massive unsecured bond offering.
Where does this repricing end?
Allspring trader Mark Clegg describes each new financing announcement as "an auction for investors' balance sheets," producing spread volatility unimaginable a year ago.
Three forces are driving the repricing simultaneously: AI's inherent uncertainty, unknown payoff timelines, and rising interest rates.
This means → the critical test is no longer "is AI worth funding?" — it is whether the market can keep absorbing supply. If spreads widen further, some financing plans may be forced to the sidelines.
