CoreWeave, Nebius, and IREN shares rose overnight following a volatile week. Industry leaders expect only a handful of neocloud operators to survive, while retail investors remain bullish on the sector.
Shares of major neocloud operators CoreWeave (CRWV), Nebius (NBIS), and IREN posted gains in overnight trading late Sunday, marking a brief reprieve after a week of significant volatility. CoreWeave stock rose 2.6%, Nebius climbed 3.8%, and IREN gained 3.3%, according to market data. This rebound comes after a turbulent period in which CoreWeave shares dropped more than 20% from Monday through Wednesday, a decline that mirrored broader weakness across the AI infrastructure sector.
The recent sell-off was driven by growing investor concerns regarding the sustainability of neocloud business models, compounded by macroeconomic triggers such as a higher-than-expected inflation reading. Despite the sharp declines, CoreWeave managed to recover 6% on Thursday, supported by public comments from Nvidia CEO Jensen Huang. However, the underlying stress in the sector remains evident, with CoreWeave’s unsecured debt due in 2032 falling below 80 cents on the dollar, a level widely interpreted by analysts as a signal of financial strain.
According to a report published Sunday by The Information, industry executives expect that only seven to 10 of the hundreds of current neocloud operators will survive in the long term. The report notes that Nvidia is playing a pivotal role in supporting these firms through easier credit terms, assistance with site selection, and $20 billion in leases. This consolidation outlook is further reinforced by a Gartner report from October 16, 2026, which projects that over 80% of neocloud providers will either fail or consolidate by 2030 due to the massive capital expenditures required for AI infrastructure.
The pressure on the sector has also impacted upcoming capital raises. Data center operator Nscale is reportedly facing investor resistance to its proposed $30 billion IPO valuation. Bloomberg reported that a group of investors has urged for a lower valuation range of $16 billion to $19 billion, citing concerns after Microsoft, a major customer, pulled out of a UK data center deal due to power constraint delays. Meanwhile, retail sentiment on platforms like Stocktwits has turned “extremely bullish” for CRWV, NBIS, and IREN, suggesting a divergence between institutional caution and retail optimism as the market weighs debt risks against long-term AI demand.
