• Kerrisdale Capital has issued a short report on AI infrastructure provider CoreWeave, projecting a catastrophic 90% downside in its share price.
  • The activist fund cites concerns over the company's path to profitability, intense competition from hyperscalers, and what it deems an unsustainable valuation.
  • The report arrives as CoreWeave, which counts Microsoft and Meta as clients, is preparing for a highly anticipated public listing.

Kerrisdale Capital, known for its activist short-selling campaigns, has trained its sights on the red-hot artificial intelligence infrastructure sector, launching a scathing critique of CoreWeave Inc. In a report published Thursday, the hedge fund argued that shares of the GPU cloud provider are grossly overvalued and could face a collapse of up to 90%.

The report immediately cast a shadow over CoreWeave, which has been one of the most prominent beneficiaries of the AI boom. The company, which pivoted from crypto mining to AI cloud compute, has secured billions in debt financing and boasts long-term contracts with investment-grade clients. According to people familiar with the matter, the timing of Kerrisdale’s move is seen as a direct challenge to the company’s narrative ahead of its expected initial public offering.

Kerrisdale’s central thesis hinges on what it calls an "unsustainable" business model. While acknowledging CoreWeave’s rapid revenue growth—which sits between $50 million and $100 million annually—the report highlights the company’s expanding net losses as detailed in its S-1 filing. The short seller contends that CoreWeave is essentially a capital-intensive reseller of Nvidia GPUs, lacking a durable competitive moat against hyperscale incumbents like Amazon Web Services and Microsoft Azure.

“This is a low-margin, commodity business disguised as a cutting-edge AI play,” the report stated, according to a person who had reviewed it. “Without a radical improvement in operational efficiency, the path to profitability is a mirage.”

Efforts to reach CoreWeave executives for an immediate comment were unsuccessful. The company’s leadership, including co-founders Michael Intrator and Brian Venturo, has previously emphasized the superiority of their proprietary orchestration software and their focus on high-performance workloads that larger clouds often underserve.

The Kerrisdale report is likely to intensify the debate over the valuations of specialized AI infrastructure companies. While demand for GPU capacity remains white-hot, driven by large language model training, skeptics argue that the capital expenditure required to compete is prohibitive and that hyperscalers will ultimately dominate the market. CoreWeave’s reliance on committed, take-or-pay contracts provides near-term revenue visibility but also locks the company into heavy fixed costs.

Market reaction was swift in pre-market trading, with shares of special purpose acquisition vehicles linked to the company falling sharply. The success of CoreWeave’s public market debut now faces a significant new hurdle as it must convince a skeptical investor base to look beyond the short seller’s claims and focus on its long-term contract book and technological differentiation.
