CoreWeave Sinks 11%, Nebius Tumbles 9% as Hyperscaler Spending Jitters Rattle AI Cloud Stocks; Cloudflare Plunges 12%, Snowflake Drops 9%

AI cloud stocks are falling again as investors rethink how much the biggest tech spenders will keep paying for outside computing power. CoreWeave (NASDAQ:CRWV) stock recently traded at $54.34, down 11%. The decline compounds a rough year for the graphics processing unit (GPU) cloud provider, which is now down 24% year to date (YTD).

Nebius Group (NASDAQ:NBIS | NBIS Price Prediction) stock is at $156.73, down 9%. Even so, Nebius remains up 87% YTD. Like CoreWeave, Nebius is a so-called neocloud: a company that fills data centers with high-end AI chips and rents that computing power to AI labs and large tech firms. Because a handful of big customers sign most of the contracts, both companies depend heavily on those customers’ spending plans.

Microsoft and Alphabet Spending Signals Rattle the Neoclouds

Selling in the group stepped up after Microsoft reported capital spending that came in below expectations on October 28, sending CoreWeave and other neocloud stocks lower. For businesses that sell capacity to hyperscalers (the giant cloud operators), a slower Microsoft expansion raises the question of how much outside computing power the largest buyers will need.

Alphabet (NASDAQ:GOOGL) unit Google followed with a record loss of market value, shedding more than $500 billion on October 29 after its report. Quarterly free cash flow at Google came in at negative $9.1 billion, worse than the negative $3.5 billion Wall Street analysts expected.

Evercore ISI strategist Julian Emanuel expects the hyperscaler cohort to stay cash-negative, with losses near $200 billion over the next year. That outlook matters for CoreWeave and Nebius, since buyers burning cash may push harder on price or slow new contracts while both neoclouds borrow heavily to build ahead of demand.

Credit worries have also hung over CoreWeave through October, as investors question how highly leveraged data center builders will handle higher borrowing costs. Nebius has tried to ease that concern, with chief operating officer Ophir Nave pointing to more than $40 billion in investment-grade customer commitments on long-term contracts as another funding source.

Cloudflare and Snowflake Get Pulled Into the AI Cloud Selloff

Cloudflare (NYSE:NET) stock is at $274.14, down 12%, a sharper slide than CoreWeave’s. The drop comes after a strong quarter: on August 6, Cloudflare reported Q2 2026 revenue of $696.1 million, up 35.9% year over year (YoY), and raised its full-year guidance. Despite the selloff, Cloudflare stock remains up 39% YTD.

Snowflake (NYSE:SNOW) stock is at $299.63, down 9%. On September 2, the data platform reported Q2 FY2027 revenue of $1.55 billion, up 35.1% YoY, and lifted its full-year product revenue outlook. After the decline, Snowflake stock is still up 37% YTD.

Why CoreWeave Carries More Balance-Sheet Risk Than Cloudflare and Snowflake

CoreWeave owns the hardware it rents out, signs long contracts with a small group of large customers and funds the expansion largely with debt. Speaking on the August 11 call, CEO Michael Intrator said, “Our near-term capacity remains effectively sold out.” Nebius runs a similar model, though it has leaned on customer prepayments and introduced an asset-light partnership approach.

Cloudflare deliberately stayed out of the AI capital spending race. CEO Matthew Prince stated on the August 6 call, “We’re in a different business than hyperscalers: they’re leasing compute; we’re selling work getting done.” Snowflake makes money as enterprises consume its governed data and AI platform, so its results track customer usage more than chip financing.

CoreWeave’s Next Earnings Report Could Set the Tone for Neoclouds

Earnings season could amplify the selling while sentiment is this fragile. CoreWeave and Cloudflare both have reports coming up, Nebius will report third-quarter results before the market opens on November 12, and Snowflake reports later. CoreWeave’s report will test whether customer demand holds up as hyperscalers rethink their budgets.

The bulls can point to CoreWeave’s revenue backlog of $104.2 billion as of June 30, along with more than $25 billion in net new customer commitments added early in Q3 2026. Debt is the drag, as CoreWeave’s interest expense rose to $640 million in Q2 from $267 million a year earlier.

A slide like CoreWeave’s shows retirement-minded readers how quickly a portfolio concentrated in high-growth AI infrastructure names can swing, which is why spreading money across sectors matters. The picks and shovels of the expansion, power, cooling and networking suppliers, often get overlooked in favor of the chipmakers (we rounded up seven of them in a free report on the AI infrastructure trade). Signals to watch for include hyperscaler capital spending commentary, neocloud financing costs and the upcoming earnings reports. Until the debate over hyperscaler spending resolves, caution could make sense for investors.
