Neocloud shares including CRWV, NBIS, IREN and APLD fell sharply, giving up their best week in over two months as AI capex worries tied to GOOGL and MSFT weighed on the group.
Shares of AI infrastructure providers fell Thursday before the market opened after Microsoft Corp. (MSFT) and Alphabet Inc. (GOOG, GOOGL) reported quarterly capital spending below Wall Street expectations. The results revived concerns about the pace and sustainability of hyperscaler spending that has fueled the artificial intelligence boom.
**Neocloud Stocks Give Up Strong Weekly Gains**
CoreWeave Inc. (CRWV) fell about 5% in pre-market trading, Nebius Group NV (NBIS) dropped 6%, IREN Ltd. (IREN) declined 4%, and Applied Digital Corp. (APLD) slid 4%, according to Benzinga Pro data.
The declines erased much of what had been a strong week for AI infrastructure stocks. CoreWeave was on track for its best week in 11 weeks, and Nebius was heading toward its strongest weekly performance in 10 weeks. IREN was on pace for its best week in seven weeks, and Applied Digital had been headed for its strongest week in 23 weeks.
The sharp reversal highlights how sensitive the neocloud trade has become to signals from the largest AI infrastructure spenders.
**Microsoft and Alphabet Capex Fall Short of Estimates**
Microsoft reported $45.2 billion in capital expenditures and finance leases for the quarter, roughly 30% higher than a year earlier but below the $50.7 billion average analyst estimate, according to StreetAccount as cited by CNBC.
Alphabet also came in below expectations, reporting $51.36 billion in capital expenditures against the $55.09 billion analysts had expected.
Both companies continue to spend enormous sums on AI infrastructure, but the misses have raised questions about whether hyperscalers can sustain the rapid pace of spending that has underpinned demand for neocloud providers.
**Elon Musk's Neocloud Shakeout Warning in Focus**
The concerns come as investors already question the financing model behind the AI infrastructure boom.
Market commentator Nicholas Mugalli recently warned that data-center delays and soaring construction costs could pose an existential challenge for highly leveraged neocloud operators. He cited reports of customers demanding late penalties exceeding $5 million per day, up from roughly $1 million previously.
Tesla Inc. and Space Exploration Technologies Corp. (SPCX) CEO Elon Musk separately warned that debt markets have "almost entirely shut off access to money" for companies without substantial revenue outside AI data centers. He predicted "guppy-level death and consolidation" among the more than 200 neocloud providers.
