Microsoft's stock plummeted 25% in Q1 2026, marking its worst quarterly performance since the 2008 financial crisis. Despite $146 billion in AI capital expenditures, Microsoft's Copilot has struggled with adoption, attracting only 6 million daily active users compared to ChatGPT's 440 million. Investor confidence has been further shaken by disputes over Microsoft's exclusive agreement with OpenAI, as well as concerns about the company's massive AI investments not yielding expected revenue returns. The forward P/E ratio for Microsoft has contracted to around 20x, the lowest since 2016, briefly falling below the S&P 500 index level. Wall Street remains largely optimistic, with 63 out of 67 analysts issuing a "Buy" rating, though some have lowered their price targets. Microsoft's next earnings report on April 28 will be closely watched for signs of progress in its AI strategy and financial performance.
