What do CoreWeave and Nebius actually do?

Both companies operate in the neocloud space, providing AI-focused cloud computing. Their core concept is to give clients everything they need to build, train, and run AI applications.

Why are these companies considered riskier than first-wave AI stocks?

Neither CoreWeave nor Nebius is profitable yet, and both are heavily investing in building and acquiring data center space—which is expensive. They must raise money through issuing shares or taking on debt to fund these operations, creating shareholder dilution and rising debt levels, whereas first-wave AI stocks like Nvidia were generally guaranteed winners.

What is CoreWeave's revenue backlog?

CoreWeave's revenue backlog reached nearly $100 billion（約16兆円）. The company will work to convert a large part of that backlog into actual revenue over the next few years.

CoreWeave, Nebius emerge as AI cloud winners—but face execution risks

Yahoo Finance AI17h ago5 min read

Key takeaway

CoreWeave and Nebius are emerging as major players in AI-focused cloud computing, with CoreWeave posting $2.1 billion（約3400億円） in Q1 revenue and a $100 billion（約16兆円） backlog, while Nebius showed 684% year-over-year revenue growth. Both companies have attracted major contracts from Microsoft and Meta Platforms and backing from Nvidia, positioning them as potential winners in the next wave of AI investing. However, both face execution risk: they are heavily investing in expensive data center infrastructure without yet being profitable, requiring ongoing capital raises that dilute shareholders and increase debt levels.

3 Key Points

What happened
Two neocloud companies—CoreWeave and Nebius—are growing rapidly as AI-focused cloud computing providers. Nebius posted Q1 revenue growth of 684% year over year, with 547% growth expected in 2026 and 233% in 2027. CoreWeave's Q1 revenue rose 112% year over year to $2.1 billion（約3400億円）, with a $100 billion（約16兆円） revenue backlog; analysts expect 147% growth in 2026 and 98% growth in 2027. Both have major contracts with Microsoft and Meta Platforms and backing from Nvidia.
Why it matters
These companies represent a potential second wave of AI investing, offering greater upside than first-wave winners like Nvidia and Broadcom. However, both are heavily investing in data center infrastructure without a profitable base business, meaning they must raise capital through shares or debt, creating shareholder dilution and rising debt levels. Neither company is profitable, so there is significant execution risk—if they can build an AI computing empire and deliver profits, they could be excellent investments, but there is no guarantee.
What to watch
CoreWeave and Nebius are not as surefire as the first wave of AI stocks. Investors should monitor each company's ability to manage debt, convert CoreWeave's $100 billion（約16兆円） revenue backlog into actual revenue, and achieve profitability while scaling data center operations over the next few years.
