Microsoft’s market cap briefly hit $4 trillion, thanks to OpenAI restructuring. Microsoft holds a $135 billion stake in OpenAI, 27% of the company, which is almost 10 times its initial $13.75 billion investment. Barclays analyst Raimo Lenschow sees this as a positive move for Microsoft, removing recent stock pressures. Microsoft secured three AI deals in one day, including agreements with Lambda and IREN. The IREN contract is worth $9.7 billion over five years, with Dell providing equipment. Microsoft also gained U.S. approval to ship Nvidia chips to the UAE, planning $8 billion investments there. Microsoft’s Q1 2026 earnings showed revenue up 18% to $77.7 billion, operating income up 24% to $38.0 billion, and net income up 12% to $27.7 billion. Bank of America analyst Brad Sills raised his price target to $640, citing Azure’s growth and renewed AI partnerships.
