CoreWeave (CRWV) has lost more than a third of its market value in October, with the stock down nearly 40% over the past month. The selloff has dragged down the wider neocloud sector — Nebius and IREN have each fallen at least 30% this month, according to CNBC — and it has put a harsh spotlight on the roughly $52 billion of debt CoreWeave took on to build AI data centers.
The $52 billion question
CoreWeave's revenue is growing fast. It booked about $2.5 billion in the second quarter, up 112% year over year, and more than doubled from the same period a year earlier. But the company's debt load has grown alongside it, and credit markets are now pricing in real stress. Its unsecured bonds yield about 15%. The spread on its credit default swaps has passed 11%.
Those are not the numbers of a company investors view as safe. On Oct. 14, CRWV sank 15% in a single session — its steepest one-day fall since February. The following day, Nvidia CEO Jensen Huang said CoreWeave needs no backstop from the chipmaker and that its cost of capital is actually decreasing. The stock kept falling anyway.
How CoreWeave got here
The company started in 2017 as Atlantic Crypto, mining Ethereum on GPUs. Two years later it renamed itself CoreWeave and repurposed the hardware to rent out computing power. That pivot turned out to be well-timed. Nvidia now supplies chips to CoreWeave, owns about 9% of the company, and has committed to buy up to $6.3 billion of its capacity if no other customer does.
That arrangement is a big part of the bull case. It's also the part that worries people. A backstop from a supplier, and a supplier that is also a shareholder, makes CoreWeave's revenue look less like a free-market outcome and more like a related-party guarantee — at least to critics.
The Core Scientific deal that wasn't
CoreWeave has leased space from Core Scientific (CORZ), a bitcoin miner shifting toward AI hosting. In October, Core Scientific shareholders blocked a $9 billion CoreWeave takeover. That leaves CoreWeave without a deal that would have consolidated some of its infrastructure footprint and, at least in theory, made its cost structure simpler to defend.
For a company that carries this much debt, the loss of a $9 billion acquisition isn't a small thing. It doesn't help the narrative that CoreWeave's growth is best understood through the vendors and landlords it depends on.
What to watch
The October selloff has wiped out a large chunk of value across the neocloud complex. CoreWeave's next quarterly report will be the first real test of whether the revenue growth is still there and whether the credit markets calm down. Until then, the company is stuck in an uncomfortable position: the fundamentals are improving, and the financing costs are getting worse. Both can be true. Investors are currently treating the second one as the story.
