Microsoft's Earnings and AI Demand

Analyst Perspectives

The strong AI demand reflected in Microsoft's report has led to some positive analyst sentiment. Citi analyst Tyler Radke upgraded CoreWeave's stock from neutral to buy, setting a price target of $160, which implies a 55% upside from recent closing prices 1
