Microsoft shares rose 15.5% on July 30, while Meta fell 8%, giving investors two sharply different ways to assess Big Tech’s AI infrastructure boom. Azure revenue increased 43%, while full-year Azure revenue exceeded $100 billion for the first time. Microsoft also operates several commercial platforms that can use the same infrastructure, including Azure, Microsoft 365 and GitHub. Its company gross margin percentage fell year over year, driven partly by the sales mix shifting toward Azure and continued AI infrastructure investment. According to Meta’s second-quarter results, revenue increased 28% to $60.8 billion.
