One year after CoreWeave's turbulent IPO, the AI cloud provider's stock has significantly underperformed rival Nebius Group. While CoreWeave shares have more than doubled since their $40 debut, they've fallen 55% from a June peak of nearly $184. Meanwhile, Nebius shares have soared about 350% since CoreWeave's IPO, now trading just 16% below their October record.

Analysts say the divergence stems from Nebius's stronger balance sheet and less aggressive infrastructure spending. CoreWeave, which raised $1.5 billion in its IPO after scaling back from a planned $2.7 billion offering, has invested heavily in building data centers to support AI workloads. Both companies serve as neocloud providers, offering specialized high-performance computing infrastructure to hyperscalers like Alphabet and Microsoft.

Despite CoreWeave's projected $12.5 billion revenue in 2026—four times Nebius's estimated sales—the company faces mounting concerns about its heavy spending and reliance on key contracts. Analysts expect neither company to turn annual profit until 2028, with CoreWeave's projected loss of $1.7 billion this year far exceeding Nebius's $660 million shortfall. The pivotal moment for both firms is expected in 2027, when the industry's profitability inflection point could trigger a re-rating of their stocks.
