Nebius (NBIS) stock analysis, September 2, 2025: NBIS breaks $68 support, tests $66 after three drops in four sessions

Published September 2, 2025 · NBIS chart, levels and live analysis

Key Updates

Nebius continues its pullback, down -2.66% to $66.50 since the last report, marking the third decline in four sessions and a break below the key support level of $68. The stock has come under pressure from growing worries about an "AI bubble," which has hit technology names in the artificial intelligence space particularly hard as investors await important macroeconomic data.

Current Trend

Despite the short-term correction (-5.02% over five days), the longer-term trend remains firmly positive, with a striking +140.08% gain year-to-date and +104.69% over six months. The monthly move shows steady strength at +27.89%, pointing to sustained fundamental investor interest. The current pullback looks technical after a big run.

Investment Thesis

The thesis rests on Nebius positioning itself as a key player in AI infrastructure, with the potential to benefit from rising demand for computing power and cloud solutions. The company remains at the center of the AI technology wave, even with near-term market concerns about sector valuations.

Thesis Status

The thesis still holds, but faces short-term challenges. The current decline reflects broader market sentiment on AI valuations rather than any fundamental problem at the company. The strong yearly gain (+140.08%) supports the long-term positioning, though caution is warranted in the near term given the possibility of further sector weakness.

Key Drivers

The main negative driver is concern about an "AI bubble", which has weighed on a wide range of tech stocks in the sector. Adding pressure is the market's focus on the August jobs report and uncertainty around Fed policy, creating a cautious backdrop for risk assets.

Technical Picture

The stock has broken support at $68 and is testing the next level near $66. The short-term trend has turned down after hitting local highs above $70. Key support sits in the $65-66 zone; a break below that could open a move toward $60. Getting back above $70 would require clearing resistance and an improvement in sentiment toward AI stocks.

Bull Case

  • Exceptional yearly performance of +140.08% shows fundamental strength in the business model and market recognition of the company's potential
  • Solid six-month gain of +104.69% confirms the long-term trend and institutional interest
  • Monthly rise of +29.89% points to continued near-term investment interest despite the recent pullback
  • Positioning in AI infrastructure provides exposure to one of the most promising technology trends
  • The current pullback could offer long-term investors a more attractive entry point

Bear Case

  • Growing fears of an "AI bubble" create systemic risk for the entire sector and could trigger a significant repricing
  • Uncertainty over Fed policy and macroeconomic data is hurting risk appetite
  • The short-term downtrend (-5.02% over five days) could accelerate if key technical support levels break
  • Rich valuations after a big run leave the stock vulnerable to any negative news or shift in market sentiment
  • Broader pressure on AI names could fuel further rotation into more traditional assets
