Why is Nebius stock rallying today?

Nebius Group NV stock rallied 10.1% in morning trading, bouncing decisively off Thursday’s bruising losses as a sector-wide relief rally in AI cloud and neocloud infrastructure names took hold across the market. The rebound comes after the stock was caught in a sharp sell-off driven by a Bloomberg report that Microsoft had tightened oversight of data center projects involving Nebius and peers, raising concerns about construction delays and capital deployment.

The primary catalyst lifting Nebius today is a sympathy move sparked by competitor IREN’s fiscal first-quarter 2027 results, released after Thursday’s close. IREN reported total revenue of $228 million — beating analyst estimates — while its AI Cloud segment saw revenue nearly triple sequentially, demonstrating that underlying demand for neocloud GPU infrastructure remains robust despite the financing anxieties that have hammered the sector. The strong IREN print helped reframe Thursday’s broad sell-off as sentiment-driven rather than a fundamental deterioration of the neocloud business model, drawing dip buyers back into names like Nebius.

Adding to the recovery, analysts continue to view Nebius favorably ahead of its own third-quarter 2026 results, due November 12. The company’s 12-month median price target of $276, based on coverage from 26 analysts, implies substantial upside from current levels, and Citi maintained its Buy rating on the stock today. The broader Nasdaq is advancing nearly 2.0% on the session, providing a supportive tailwind for high-beta AI infrastructure names as chip stocks also stabilize after Thursday’s rout.

Taken together, IREN’s earnings-driven proof-of-concept for the neocloud sector, a recovering technology market, and growing anticipation around Nebius’s upcoming earnings report have combined to push shares sharply higher today — partially unwinding what many market participants viewed as an outsized reaction to Microsoft’s project scrutiny.
