Elon Musk has expressed a bearish outlook on the future of neocloud providers, arguing that mounting financing pressures could trigger widespread failures and consolidation across the sector.

In a post on X on Sunday, the SpaceX CEO questioned the sustainability of companies such as CoreWeave and Nebius, which focus on supplying computing infrastructure for artificial intelligence workloads. Musk said lenders were becoming increasingly hesitant to finance businesses whose revenue depends overwhelmingly on AI data centers.

Musk noted that SpaceX had obtained $40 billion in debt financing to purchase graphics processing units (GPUs). However, he argued that SpaceX differs from neocloud operators because it generates income from multiple businesses, including its Starlink satellite internet service and rocket launches.

Against that backdrop, Musk predicted severe industry shakeouts. “That means the 200+ neoclouds are going to see guppy-level death and consolidation,” he wrote, adding that only a limited number would survive.

His comments came in response to venture capitalist Chamath Palihapitiya, who had described neocloud companies on X as “disorganized and poorly capitalized.”

Musk also rejected speculation that SpaceX might be criticizing the sector to push down share prices before acquiring companies at a discount. Responding to a separate discussion on X, he stated: “SpaceX is not buying any neoclouds. Pointless.”

Neocloud Stocks Slide as Financing Concerns Grow

The remarks come during a difficult period for publicly traded neocloud companies, whose shares have come under pressure amid concerns about heavy borrowing and their reliance on a narrow range of revenue sources.

CoreWeave shares have fallen approximately 37% over the past month, while Nebius has lost around 30% over the same period.

Nvidia CEO Jensen Huang, by contrast, has continued to emphasize the strength of demand for AI computing infrastructure, describing demand for AI cloud services as “off the charts.” Nvidia has also provided significant backing to several companies in the sector, including CoreWeave, Nebius, Iren and Lambda.

Data Center Delays Could Leave Computing Capacity Unused

Musk raised another concern in a separate X post on Friday, warning that the industry could end up with substantial amounts of “stranded compute” in data centers that are only partially completed.

The term refers to computing equipment that is available but cannot be put into operation because the facilities housing it lack the infrastructure needed to support it, such as sufficient electrical power.

A recent example involves Amazon Web Services. As Business Insider's Eugene Kim reported last week, AWS is expected to receive Nvidia GB300 server racks worth approximately $5 billion. However, the cloud provider reportedly lacks sufficient power capacity at its data centers to deploy the equipment immediately, leaving the units to be stored in warehouses until the facilities are ready.

The broader data center construction pipeline is also facing uncertainty. A recent Bernstein Research report estimated that only about 35% of the data center capacity planned in the United States would ultimately be built.

According to the report, established technology companies such as Amazon, Google, Meta and Microsoft are better positioned to complete their projects because of their experience constructing and operating large-scale data centers.

Less-established developers face greater uncertainty. The report questioned whether projects announced by newcomers, including celebrity investor Kevin O'Leary's company, which has committed to developing 15 gigawatts of data center capacity, would materialize. Such ambitious capacity announcements have been derisively labeled “bragawatts.”

AI Model Startups Also Face Growing Scrutiny

The challenges extend beyond neocloud providers to a group of emerging AI developers sometimes referred to as “neolabs.”

These startups focus on building AI models and include Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, and Safe Superintelligence, co-founded by former OpenAI chief scientist Ilya Sutskever.

Despite attracting substantial funding, these companies face intense competition from established frontier AI developers, particularly Anthropic and OpenAI.

Several venture capitalists recently told Business Insider's Ben Bergman that enthusiasm for neolabs may have outpaced their prospects, making investment in the category an increasingly divisive issue among investors.
