Nebius Group surged 16.55% in after-hours trading, driven by a landmark $17.4 billion AI infrastructure deal with Microsoft, which validates its full-stack platform and secures long-term revenue through 2031. Analyst upgrades, including a raised $130 price target by BWS Financial and reaffirmed "Buy" ratings, further fueled optimism.
