CoreWeave Inc.’s shares tumbled after the cloud-computing provider reported a wider quarterly loss and gave a disappointing earnings outlook, raising concerns about its rapid AI data center expansion pressuring profit margins.

CoreWeave easily topped quarterly revenue estimates on Tuesday as the rapid adoption of artificial intelligence tools boosted demand for its cloud services, but a bigger-than-expected net loss sent its shares slumping 10% after the bell.

The AI-focused data center operator beat revenue forecasts but reported a $291 million quarterly loss, rattling investors.
