Shares of CoreWeave Inc. (CRWV) are having a rough start to the week. The decline is part of a broader risk-off mood in the market, with the Nasdaq Composite dropping as geopolitical tensions flare. But for CoreWeave, there are a few specific reasons the stock is under pressure.
Short Sellers Are Piling In
One notable development is that short sellers have been increasing their bets against the company. During the last reporting period, the number of shares sold short jumped from 46.67 million to 50.71 million. That means a hefty 18.86% of the company's available shares are now held in short positions. With an average daily trading volume of 23.00 million shares, it would take those short sellers roughly 2.2 days to buy back and cover their positions if they needed to exit in a hurry.
The Guidance Problem
The current slide follows an even steeper drop on Friday, when shares tumbled 18%. The catalyst was the company's first-quarter revenue outlook. CoreWeave told investors to expect revenue between $1.9 billion and $2 billion for the quarter. The problem? Wall Street analysts were collectively expecting about $2.291 billion. That's a meaningful miss. In a classic "look over here, not there" move, management did reaffirm its full-year 2026 revenue guidance of $12 billion to $13 billion, trying to steer focus to the long-term story.
