Musk rules SpaceX out of buying AI cloud firms as CoreWeave's debt hits $51.6 billion
The sector's best-financed buyer says buying a neocloud is "pointless," and its biggest name now owes $51.6 billion against $2.6 billion of quarterly revenue. CoreWeave, Nebius and IREN slid again overnight.

Sunday night, the one deep-pocketed buyer walked
Elon Musk spent Sunday, October 25 on X closing the door on the neoclouds' richest possible rescuer 24. "SpaceX+1.16% — SpaceX, up 1.16 percent today is not buying any neoclouds. Pointless," he wrote, hours after confirming the rocket and satellite company had closed $40 billion of debt to buy Nvidia GPUs arriving in the first and second quarters of 2027 24.
He predicted "guppy-level death and consolidation" for the sector's 200-plus players, saying debt markets have "almost entirely shut off access to money" for any company without substantial revenue independent of AI data centers 1. CoreWeave+4.47% — CoreWeave, up 4.47 percent today (CRWV) and Nebius+1.99% — Nebius, up 1.99 percent today (NBIS) each fell 2.3% overnight, IREN+4.97% — IREN, up 4.97 percent today 2%, extending a two-week slide 1.
Growth the credit market refuses to underwrite
A neocloud rents out AI computing bought mostly with borrowed money, which is exactly the model Musk says lenders have stopped funding. CoreWeave, the largest, booked about $2.5 billion of second-quarter revenue, up 112% year over year, and still lost more than a third of its value in October 3.
Its unsecured bonds yield about 15%, and the cost of insuring its debt against default passed 1,140 basis points intraday on October 15 37. By the filings' own count, the debt stack has outrun the revenue that services it for six straight quarters 5.
CoreWeave's debt has grown almost fivefold in six quarters, to $51.6 billion

The bill lands while rivals bridge
Bernstein cut its CoreWeave target to $51 from $74 on October 23 and estimates the company must raise $85 billion to fund its committed backlog, with $9 billion already covered 7.
Nebius took a $3.5 billion, 364-day Citi loan on October 22 at a floating benchmark rate plus 2.75 percentage points; its chief executive Arkady Volozh conceded that asset-backed and debt financing had "temporarily dried up," while insisting Nebius can still fund "this gigawatt" 68.
Chamath Palihapitiya added the 2027 risk: capacity "bought and paid for but effectively underearning" 1. That continues the split this page charted when AI debt priced at 15% for CoreWeave and 6.25% for Iron Mountain 1.
The floor, and the fight over it
The other side is real. Nvidia+2.14% — Nvidia, up 2.14 percent today owns about 9% of CoreWeave, has committed up to $6.3 billion of capacity backstops, and its chief executive Jensen Huang said on October 15 that CoreWeave's "cost of capital is actually decreasing" 3. CoreWeave's Mike Intrator wrote to staff that the backlog "more than supports all of our debt obligations," and JPMorgan ($125) and Wells Fargo+0.84% — Wells Fargo, up 0.84 percent today ($160) still rate the stock a buy 7. Bernstein itself says Nvidia would step into a true downturn, which "raises the floor" 7.

What to watch is the price of the next refinancing, not the next Musk post: CoreWeave's $85 billion need is unfinanced, and Nebius's bridge expires in October 2027 67. When the cheapest borrower in AI compute rules himself out as a buyer, the floor under these stocks is a chipmaker's promise.
