    Listen to the news

    Nebius Group (NasdaqGS:NBIS) has been hit by a sharp repricing, with worries over rising borrowing costs, heavy sector debt and Gartner’s overcapacity warning weighing on AI-focused infrastructure providers.

    Nebius Group’s share price has whipsawed, with a 1-day share price return of 1.29% after a 7-day decline of 14.25% and a 30-day fall of 9.14%. However, the year-to-date share price return of 109.46% and 1-year total shareholder return of 53.13% show that longer term momentum is still positive, even as recent sector news and debt concerns have cooled enthusiasm.

    For Nebius Group, bulls point to strong AI cloud contracts and a sharp pullback, while bears focus on heavy debt and overcapacity risk. Which side does the current valuation actually support next?

    Most Popular Narrative: 28% Undervalued

    Nebius Group last closed at $188.41, while the most followed narrative pegs fair value around $260. That gap is what bulls and bears are really arguing about.

    The $260 fair value represents our working estimate of what NBIS could be worth if the company delivers strong AI-cloud growth and improves profitability. It should be treated as an upside target rather than evidence that the shares are clearly cheap, because NBIS trades at approximately 42.3 times sales, compared with a peer average of approximately 9.8 times.

    See why 17 investors see Nebius Group as 28% undervalued.

    Result: Fair Value of $259.97 (UNDERVALUED)

    Still, the story around Nebius Group can flip quickly if AI Cloud utilisation lags capacity build outs or if fresh dilution from funding overwhelms any revenue traction.
