So CoreWeave got absolutely hammered last week. The stock dropped nearly 19% after their earnings call, and honestly the numbers explain why. They reported a bigger stock market loss than expected even though revenue doubled in Q4, which sounds backwards but that's what happened when spending explodes faster than income grows.

The real issue is their guidance and capex plans. Management is talking about spending $35 billion this year on infrastructure buildout, which is absolutely massive. Q1 revenue guidance came in at $1.95 billion, below what analysts were modeling. When you combine widening losses with that kind of spending trajectory, investors start asking hard questions about when this company actually turns profitable.

It wasn't just CoreWeave getting hit either. You saw the whole AI infrastructure space take a breather that day. Nvidia dropped 4%, Microsoft fell 2%, and the Nasdaq overall lost about 0.9%. Looks like investors are reassessing how much they want to pay for these high-growth cloud computing plays right now.

The stock market loss narrative is real here - CoreWeave went public in 2025 and was up nearly 100% at one point, so people who bought early are still sitting on gains even after this selloff. But the path to profitability just got a lot longer with those capex numbers. Trading volume spiked to 57.7 million shares, way above normal, so there was definitely some panic selling mixed in with the repositioning.
