AI Infrastructure Leader Remains a High-Growth Story Despite Rising Questions Over Valuation
Nebius Group (NBIS) has returned to the spotlight after renowned investor Michael Burry disclosed a short position in the company, triggering renewed debate over the valuation of one of the artificial intelligence infrastructure sector’s fastest-rising names.
The disclosure contributed to a 13.3% one-day decline in Nebius shares as investors weighed concerns surrounding the company’s ambitious data center expansion plans. Despite the sharp pullback, the stock continues to post impressive long-term gains, delivering a 7.3% return over the past 90 days and an extraordinary 190.7% total shareholder return over the last year.
Nebius has attracted significant investor interest thanks to its strategy of building AI-focused cloud and computing infrastructure designed to support the rapidly growing demand for artificial intelligence applications. As enterprises continue investing in AI workloads, the company has positioned itself as a key player in supplying the computing capacity required for next-generation models.
However, Burry’s bearish stance has intensified questions about whether current expectations have become overly optimistic. Critics argue that Nebius’ premium valuation assumes aggressive execution, sustained demand, and successful expansion of its data center footprint—all of which leave little room for operational setbacks.
Supporters remain optimistic. One widely followed valuation model estimates a fair value of $245.43 per share, well above the recent closing price of $189.88, suggesting the stock may still offer meaningful upside if management delivers on its growth targets.
For investors, the debate now centers on a familiar question in the AI sector: whether Nebius represents an attractive long-term opportunity or a stock whose remarkable growth story has already been largely priced into the market.
