Microsoft beat analysts' expectations in its latest quarterly report, driven partly by its cloud and artificial intelligence divisions. The tech giant reported US$90 billion in revenue and US$35.8 billion in net income in the last quarter of its fiscal year which ended in June. Its AI-powered tool Copilot has over 30 million paid users, showing "confidence" from customers, CEO Satya Nadella said. Microsoft saw a US$3.2 billion gain from its investment in Anthropic, while investments in OpenAI boosted net profit by US$480 million in its fourth quarter and US$4.9 billion for its full fiscal year. Major U.S. tech companies are collectively on track to pour roughly US$700 billion into AI infrastructure this year. In June, Alphabet announced it would raise up to US$80 billion in stock to fund AI efforts, with Berkshire Hathaway committing US$10 billion.
