Nebius Sinks 15% as Capex Swells and 2027 Outlook Takes a “Conservative Approach” to Build-Out
Nebius Group (NBIS) fell 15% despite Q3 revenue beat, citing lower 2026 revenue guidance and higher capex plans. The company expects $27B in 2026 and $40B-$45B in 2027, higher than analyst estimates. IREN and Applied Digital also declined. Investors question Nebius's ability to fund its build-out.
