Shares of CoreWeave (NASDAQ:CRWV) are sliding midday Monday, with CoreWeave stock down 5% to $112 as the AI cloud infrastructure provider makes its official NASDAQ 100 debut. The move turns what is usually a bullish catalyst into a textbook sell-the-news reaction.

CoreWeave stock isn't moving alone. Nebius Group (NASDAQ:NBIS) stock is dipping 1% to $283.50, and Rocket Lab (NASDAQ:RKLB) stock is also lower after joining the same index.
All three names rallied hard into today's NASDAQ 100 inclusion. The unwind on debut day reflects profit-taking after vertical moves, plus a broader risk-off tape that's pressuring AI infrastructure exposure across the board.
Sell-the-News on a Known Catalyst
Index inclusion typically forces passive buying from funds tracking the benchmark, which usually supports the stock. Yet, CoreWeave, Nebius, and Rocket Lab stock are all falling today, a classic pattern when traders sell into a well-telegraphed event after a big run-up.
The runs were enormous. CoreWeave stock was up 65% year to date (YTD) through last Thursday, while Nebius stock soared 243% YTD. Rocket Lab stock, meanwhile, had climbed 54% YTD.
CoreWeave's fundamentals back the momentum but also justify caution. The company posted solid recent quarterly results with a large revenue backlog, but still reported a sizable net loss. Analysts carry a price target of $140.18 on CRWV stock.

Risk-Off Tape Amplifies the Move
The selling isn't isolated to the debut names. Alphabet (NASDAQ:GOOGL) stock is down 5% intraday, and Amazon (NASDAQ:AMZN) stock is off 4% as AI capital-expenditure jitters and geopolitical headlines drive a broad rotation out of growth.
The VIX is sitting at 16.78, in normal territory, but the daily uptick of 2% signals a cautious market, not a complacent one. That's a tough backdrop for richly valued momentum names trying to digest forced index buying.
CoreWeave stock trades at a price-to-sales ratio of 10x with deeply negative margins, while Rocket Lab stock carries a price-to-sales ratio of 99x and a beta of 2.5. When sentiment turns, these are often the first stocks to feel the pressure.
Reddit Was Already Euphoric
Retail enthusiasm was peaking right into the debut. Reddit sentiment for Nebius hit 95 (very bullish) on Friday morning, driven by a viral r/WallStreetBets post that gathered 1,616 upvotes claiming Nebius had made the author "a millionaire" in two years.
Rocket Lab sentiment ran bullish too, scoring 72 as of early Monday. Peaks in retail euphoria into known catalysts often coincide with the kind of distribution playing out on the tape this afternoon.
What to Watch
Investors can watch for whether CoreWeave stock and Nebius shares stabilize into the close, when passive index funds typically finish rebalancing. A late-day bounce can signal absorption; continued weakness may suggest that the unwind has further to run.
Any commentary from CoreWeave CEO Michael Intrator or Nebius CEO Arkady Volozh, plus fresh analyst notes on the debut cohort, can shape the next share-price move. Until then, the AI cloud trade looks like one investors are sizing carefully rather than chasing.
