CoreWeave Faces IPO Reality Check: What Went Wrong With the Hot AI Cloud Provider?

The AI sector has been buzzing with big-money deals, groundbreaking technologies, and a seemingly insatiable investor appetite. Amid this excitement, CoreWeave—the high-flying cloud computing provider powering much of the generative AI boom—recently completed one of the largest AI-related IPOs in history. But beneath the surface, cracks are beginning to appear. Following its Wall Street debut, CoreWeave’s stock has taken a significant hit, raising new questions about market expectations and what the future holds for this ambitious AI infrastructure company.

What is CoreWeave and Why Did It Matter?

CoreWeave operates cutting-edge data centers in the US and Europe, specializing in renting out high-performance GPUs to major artificial intelligence players. The company was founded in 2017 and has staked its claim as a crucial backbone for the surging demands of AI development. With flagship facilities like its $1.6 billion supercomputer data center in Texas—the world’s fastest AI supercomputer, according to Nvidia—CoreWeave has attracted an impressive roster of clients, including OpenAI, Meta, Microsoft, IBM, and Nvidia itself.

In early 2025, CoreWeave reached a milestone by announcing it would be the first to offer Nvidia’s latest GB200 NVL72 chips via the cloud—a move seen as a major advancement in AI cloud accessibility. The company continued to make headlines with the purchase of AI software specialist Weights & Biases for about $1.7 billion and a massive five-year, $12 billion AI infrastructure deal with OpenAI, even allowing the latter to get an equity stake through private share placement during CoreWeave’s IPO.

CoreWeave’s IPO: Sky-High Hopes Meet Market Skepticism

Heading into its public offering, expectations were enormous. The IPO, which ultimately raised $1.5 billion, was reduced from an initial target of $2.7 billion, reflecting cautious signals from institutional investors. Despite landing the largest AI IPO by capital raised to date, the stock sharply fell in the opening days of trading.

Several factors contributed to this abrupt turn. First, CoreWeave’s rapid revenue growth has made it a darling of the AI world, but it also relies heavily on a handful of customers—most notably, Microsoft, which accounted for a striking 62% of CoreWeave’s revenue in 2024. This high dependency heightens risk for public investors seeking stable, long-term growth. Less than three years prior, the company’s largest customer represented just 16% of revenue—a much more balanced profile.

Secondly, CoreWeave’s main business is renting its powerful GPUs not directly to start-ups or AI companies, but often acting as an overflow provider for major cloud giants like Amazon, Google, and Microsoft. These hyperscalers turn to CoreWeave when their own data centers reach capacity. This means CoreWeave’s fortunes are closely tied to these large players’ own infrastructure strategies and willingness to rent excess capacity.

Debt, Growth, and the Pressure to Deliver

Another source of concern arises from CoreWeave’s aggressive expansion and mounting financial commitments. The company took on substantial debt to build out its infrastructure, and it carries significant ongoing obligations to keep up with surging demand. In July 2025, CoreWeave closed a $2.6 billion secured debt facility—strengthening its position, but adding pressure to deliver sustained growth and profitability.

Mergers and acquisitions have also played a key role in CoreWeave’s recent strategy. In March 2025, CoreWeave announced the $1.7 billion acquisition of Weights & Biases, a move intended to deepen its AI ecosystem and tech stack. In July, after previously rebuffing CoreWeave’s buyout offer, blockchain infrastructure company Core Scientific agreed to a $9 billion takeover—an acquisition aimed at reducing CoreWeave’s future liabilities and expanding its capabilities. However, news surfaced in August that some major shareholders planned to vote against the deal, reflecting uncertainty about the financial merits and long-term synergies of the tie-up.

Investor Sentiment: From FOMO to Prudence

CoreWeave’s story is emblematic of the broader reset happening in the AI infrastructure market. A year ago, anything AI-related drew unbridled enthusiasm and frothy valuations. Now, as rapid customer concentration, heavy capital expenditures, and a competitive landscape become ever clearer, investors are applying heightened scrutiny.

This is not to say CoreWeave is in trouble—far from it. The company remains a leading player with powerhouse clients and a crucial role in the evolving AI ecosystem. It closed the second quarter of 2025 with robust results and continues to power the next wave of enterprise AI solutions. But if its challenging IPO serves as a barometer, even the most promising tech firms aren’t immune to market realities. For CoreWeave and its investors, the coming months will likely be a test of whether extraordinary vision can translate into sustainable, diversified growth.

The broader takeaway for financial markets is clear: The age of easy wins for hot AI startups may be over. As CoreWeave’s journey shows, success now demands more than just breakthrough technology—it requires resilience, discipline, and a business model that can withstand the scrutiny of public markets. Investors, for their part, are recalibrating, focused less on hopes and dreams and more on the fundamentals that have defined long-term winners for decades.
