Why Did CoreWeave (CRWV) Stock Plummet After Earnings

CoreWeave reported fiscal year 2025 revenue of $5.1 billion, a staggering 167.9% year-over-year increase, yet the stock fell sharply after earnings. The company posted a net margin of -22.8% and diluted EPS of -$2.81, underscoring that the business is still burning cash at scale despite its explosive top-line growth. The results are a reminder that revenue acceleration alone is insufficient to satisfy markets when losses remain deep and capital intensity is extreme in the GPU cloud buildout.

CoreWeave sits at the intersection of two of the most powerful themes in tech — AI infrastructure demand and cloud services — but it is also one of the most leveraged and capital-heavy names in the space. The company relies heavily on Microsoft as a major customer, creating concentration risk, and its debt load tied to GPU financing arrangements is significant. Any softening in AI capex from hyperscalers or a shift in GPU supply dynamics would hit CRWV disproportionately.

The post-earnings selloff creates a classic growth-vs-profitability debate. Bulls point to the revenue trajectory — 167.9% growth is almost unparalleled at this scale — and argue that losses are a function of aggressive capacity investment ahead of a demand curve that remains intact. Bears note that negative net margins at $5B in revenue suggest the unit economics have not yet proven out, and that the stock's post-IPO valuation may have already priced in years of optimistic assumptions.

The key things to watch: whether management guides to a meaningful margin inflection in 2026, whether Microsoft contract renewals or expansions are confirmed, and whether the broader hyperscaler AI capex cycle shows any signs of cooling. Until a credible path to profitability emerges in the numbers, each earnings print will be a binary event for CRWV.
