CoreWeave vs. Nebius Group: Which Artificial Intelligence (AI) Cloud Stock Has More Upside?

CoreWeave (NASDAQ: CRWV) and Nebius (NASDAQ: NBIS) are both “neocloud” providers focused on AI workloads, and both have surged in 2026—CoreWeave is up about 30%, while Nebius is up roughly 196%, nearly tripling. Nebius has outperformed so far, but the article argues the gap may not last. Both firms depend heavily on major clients like Microsoft and Meta, which can scale usage but face limited capacity. Meta’s potential cloud push previously rattled the stocks, yet Zuckerberg told investors in a Q2 call that offers for compute came “at a significant premium,” easing concerns and helping drive an August rally. Growth-at-all-costs strategy adds risk if AI demand slows, but analysts project stronger revenue growth for Nebius.
