Investors Dump Data-Centre Bonds as AI Borrowers Face a ‘Darwin Moment’

Credit markets are delivering the verdict that equity investors spent months avoiding: the debt financing the artificial-intelligence boom may be far shakier than anyone admitted. Investors are dumping bonds issued to fund some of the largest data-centre projects in the United States, pushing debt backing facilities where Meta, Nvidia and Oracle will be tenants — including projects known as “Hyperion” and “Project Excalibur” — well below par in recent weeks.

The selling has been most violent among the so-called neoclouds — the aggressive young cloud providers renting out scarce Nvidia graphics processors to AI developers — and its poster child is Nvidia-backed CoreWeave. The company’s unsecured bonds due 2032 now yield around 15 per cent, trade below 80 cents on the dollar and carry a credit spread above 1,000 basis points: levels the market associates with distressed debt, the kind normally found in CCC-rated junk or worse. As Ludovic Subran, chief investment officer at Germany’s Allianz, put it: data-centre bonds are having their Darwin moment, with the weakest credits struggling to survive.

How bad the numbers are

CoreWeave’s April-issued bonds due 2031 were yielding near 16 per cent on Thursday, changing hands at 79.15 cents on the dollar according to Tradeweb data. The cost of insuring its debt against default — its credit default swaps — has climbed to around 1,000 basis points, implying a nearly 63 per cent chance of default within five years, up from about 30 per cent a year ago. Options traders have piled into bearish bets at a record pace: volume in put options hit an all-time high on Wednesday, with investors buying contracts that profit if the shares fall below $42.50, $50 and $60 in the coming weeks.

The equity side has followed credit’s lead. CoreWeave shares cratered more than 15 per cent on Wednesday — the stock’s third-biggest drop on record — before slipping further on Thursday to their lowest level since May 2025. The stock market, as one market watcher put it, finally noticed what credit markets had been signalling for weeks. Even Elon Musk weighed in on the bond moves with a public expression of alarm.

Why credit markets moved first

Bond investors live and die by cash flows, and CoreWeave’s cash flows make uncomfortable reading. The company carries roughly $50–52 billion in debt and lease obligations; its second-quarter interest bill alone was about $640 million — exceeding its adjusted operating income. It went public in March 2025, raised its annual capital-spending forecast by $4 billion to as much as $39 billion in August, and is expected to post a $2.13 billion loss this year on nearly $13 billion of revenue, according to analyst estimates.

The business model has an inherent fragility that critics have flagged for months: neoclouds borrow heavily to buy Nvidia chips, rent out the computing capacity, and must then spend heavily again as newer chips arrive and old ones lose value. If AI demand cools — or even just grows more slowly than the debt assumes — the maths breaks. As one strategist observed this week, the market is waking up to the fact that AI demand and a profitable business model are two very different things.

The “Darwin moment”

Allianz’s Subran argues the repricing reflects execution risk that was never properly priced: the surge in credit spreads following power and construction delays shows that data-centre debt was priced too tight for the risks of actually building these things. Data centres are not just expensive to finance — they are hard to build. Power connections get delayed, construction overruns, tenants’ timelines slip, and all the while the interest clock keeps ticking.

The contagion is spreading beyond CoreWeave. Oracle’s unsecured bonds have traded like deep junk, and even debt tied to a Meta project — “Project Beignet” — has pushed to record-wide spreads, according to market watchers. Shares of Nebius, Oracle and Dell have fallen alongside, and Nvidia itself has shed more than $300 billion in market value over the past week — a reminder that the chip giant’s tens of billions invested across neoclouds and AI start-ups leave it exposed to the same repricing.

CoreWeave pushes back

Chief executive Mike Intrator has called the market reaction irrational, pointing in an internal memo to a contracted backlog of roughly $104 billion as cover for the company’s obligations. The company also has a notable backstop: Nvidia has agreed to buy any unsold CoreWeave computing capacity through April 2032 — a deal that, in theory, puts a floor under revenues.

Sceptics are unmoved. A contracted backlog is only as solid as the customers behind it, several of whom are themselves burning cash to build AI businesses of uncertain profitability. And the Nvidia backstop, while real, underscores the circularity that worries the market: the chipmaker financing demand for its own chips through the customers it has invested in. The IMF warned this month that rapid, debt-fuelled AI data-centre buildouts and circular financing practices could create interdependence that raises refinancing and contagion risks across technology and credit markets.

The macro backdrop

The selloff has been amplified by a hotter-than-expected US inflation reading, which pushed investors to reprice borrowing costs higher across the board — painful timing for the most leveraged borrowers. Bond markets stabilised somewhat on Thursday as traders bought Treasuries and other safe-haven sovereign debt, and Asian equities rebounded on Friday, but the underlying question has not gone away: can the revenues of the AI boom, however real the demand, service the debt being raised to build it?

For now, the market’s answer is bifurcated. The strongest credits — the hyperscalers with fortress balance sheets — can fund the build-out from cash flow. The weakest, as the Darwin analogy suggests, may not survive the selection pressure. What happens in between, across the vast middle of AI infrastructure finance, is the trade of the moment.

FAQs

What does “distressed debt” mean here?

It describes bonds trading at yields and prices that imply serious doubt about repayment — typically yields above 10% or prices below 80 cents on the dollar. CoreWeave’s 2032 bonds yield around 15% and trade below 80 cents, with credit spreads above 1,000 basis points — territory normally associated with CCC-rated junk bonds or worse.

What is a neocloud?

Neoclouds are newer cloud providers — CoreWeave and Nebius among them — that rent out computing power from scarce, expensive Nvidia graphics processors to meet AI demand. They typically borrow heavily to buy the chips, which leaves them exposed if AI demand cools or when newer chips force another costly upgrade cycle.

Why did CoreWeave’s CEO call the selloff irrational?

Mike Intrator points to a contracted backlog of roughly $104 billion as cover for the company’s obligations, plus a deal under which Nvidia will buy any unsold CoreWeave capacity through April 2032. Critics counter that backlogs depend on cash-burning customers and that the Nvidia arrangement highlights the circular financing the market now fears.

How did the IMF get involved?

The IMF warned this month that rapid, debt-fuelled AI data-centre buildouts and circular financing practices could create interdependence, raising refinancing and contagion risks across tech and credit markets. The warning gave institutional weight to concerns that credit investors had already been acting on for weeks.

What should investors watch next?

CoreWeave’s November quarterly results and any near-term refinancing moves are the immediate tests, alongside a March 2027 bond-document deadline that could determine whether its debt structure holds. Broader signals include bond-yield behaviour across other AI borrowers, Federal Reserve policy on rates, and whether private-credit exposure at insurers becomes the next pressure point.
