Copilot Woes Drag Microsoft Shares Down 17% in Six Months

Microsoft Corp shares have slumped roughly 17% over the past six months, erasing over $800 billion in market value from an October peak and trading under 24 times projected earnings. Investor doubts focus on sluggish Copilot AI adoption, with only 15 million paying corporate users—about 3.5% of its vast base—amid rising competition from Anthropic's Claude tools now integrated into Copilot. While Microsoft holds strong AI positioning, faster monetization is crucial to rebuild confidence and reverse the valuation slide.
