    Listen to the news

    Nebius Group (NasdaqGS:NBIS) has drawn fresh attention after William Blair began covering the stock, and the company signed a 12-year AI data center capacity deal with AIB Data Centers.

    Recent trading action has been intense for Nebius Group, with the share price at US$235.88 after a small 1-day dip of 0.62%, but a 30-day share price return of 14.33% and a year-to-date share price gain of 162.23% signal strong upward momentum. That move sits on top of a 1-year total shareholder return of 104.03% and a 5-year total shareholder return of 200.37%, while index inclusion and the new AI data center agreement have fed a debate about whether buyers are pricing in higher growth potential or simply accepting more risk in the AI infrastructure story.

    Another View on Nebius Group Valuation

    The story changes when you stop looking at fair value estimates and focus on what the market is paying for Nebius Group today. The stock trades on a P/S of 47.7x versus 3.8x for the wider US Software sector and 10.3x for peers, while the fair ratio sits lower at 38.6x.

    That gap implies investors already accept a heavy valuation premium, which can amplify downside if sentiment cools even slightly. The question is whether you believe the business can keep justifying such a stretch, or if this is where valuation risk starts to outweigh the growth story.
