NBIS is trading 9.5% down at $249.93 in pre-market, pulling back as investors lock in profits following a massive rally. This decline occurs on a day when Nebius Group launched its new AI Cloud Aether 3.6, introducing Nebius Echo for natural-language infrastructure control.

  • The stock has surged over 21% in the last 30 days and more than 300% over the past year, fueled by blockbuster Q1 earnings and major AI cloud deals, and recently gained inclusion in the Nasdaq-100.
  • The market's negative reaction today, despite the product launch, may reflect broader market volatility and caution surrounding high-multiple AI infrastructure names, leading to profit-taking.
