Why Is Nebius Group (NBIS) Stock Price Down 9.68% Today, July 28? Neocloud Profitability Fears Deepen the AI Infrastructure Selloff

Nebius (NBIS) sold off ~9.7% as investors extended de-risking across capital-intensive AI infrastructure/neocloud names amid renewed focus on funding needs, capex burdens, and uncertain profitability timelines. No company-specific same-session catalyst was identified, suggesting a sentiment-led repricing and fragile positioning after prior AI-driven strength. Near-term trading is likely to remain sensitive to sector risk appetite and peer commentary on demand, capacity deployment, and economics.
