Neocloud stocks plunge 37% as AI infrastructure spending fears mount

Nvidia-backed neocloud companies CoreWeave, Nebius, and IREN have lost more than a third of their value from recent highs as investors question whether the AI infrastructure spending cycle can sustain the valuations baked into the sector's fastest-growing names.

"The market is repricing the timeline for neocloud profitability, and the multiples these stocks carried assumed a straight-line growth trajectory that was never realistic," Rachel Kim, AI infrastructure analyst at Edgen, said. "When the VIX jumps and tech earnings loom, these are the first names to get cut."

Nebius Group shares have tumbled 37.3% from their 2026 peak, with the stock sliding 9% on Friday alone to $200.60. The pullback follows a 135% year-to-date rally that pushed the company's trailing price-to-earnings ratio to 75.87 times — among the highest in the AI cloud cohort. CoreWeave fell 7% to $75.15, leaving the stock down 38% over the past year despite a $99.4 billion revenue backlog. IREN, the bitcoin miner turned AI data center operator, has declined in sympathy with the group.

The divergence between pure-play neoclouds and diversified cloud providers underscores the selective nature of the selloff. Cloudflare shares held flat at $263.48, keeping the stock up 33% year to date. Snowflake rose 2% to $269.65. Oracle slipped 1% to $118.80, though its cloud infrastructure business grew 93% year over year last quarter. The pattern suggests investors are punishing companies whose valuations depend entirely on AI infrastructure buildout while sparing those with broader revenue bases.

The CBOE Volatility Index jumped 12% to 18.7 on Thursday, its highest close in recent weeks, as markets positioned ahead of earnings reports from major technology companies. High-beta names with elevated multiples tend to absorb the brunt of volatility-driven rotation, and the neocloud group fits that profile precisely.

Nebius's fundamentals remain intact beneath the tape noise. The company reported first-quarter revenue of $399 million, up 279.6% year over year, and guided full-year 2026 revenue to a range of $3 billion to $3.4 billion, backstopped by anchor customer commitments and strategic capital from top-tier AI partners. Wall Street maintains a consensus price target of $258.13 on Nebius, with nine Buy or Strong Buy ratings against one Sell. CoreWeave's target of $138.03 implies roughly 84% upside from current levels.

The broader question for investors is whether the neocloud selloff represents a tactical rotation or the beginning of a structural repricing. The sector's bull case rests on the assumption that enterprise AI workloads will require exponentially more computing capacity, driving demand for the specialized GPU clusters that companies like Nebius and CoreWeave operate. The bear case — now being tested in real time — is that hyperscalers such as Amazon Web Services, Microsoft Azure, and Google Cloud will capture the majority of that demand, leaving neoclouds competing for overflow capacity at thinner margins.

Nvidia, which has invested in both CoreWeave and Nebius, faces its own exposure to the group's performance. If neocloud customers scale back capacity commitments, it could signal softening demand for Nvidia's highest-end data center GPUs. Nvidia shares have not yet felt the same pressure, but the neocloud rout adds a layer of uncertainty ahead of the company's next earnings report.

For now, the tape is telling a simple story: when volatility spikes, the most speculative names get hit first. Whether that becomes a buying opportunity or a warning sign depends on whether the earnings season ahead confirms or contradicts the infrastructure spending thesis.
