Anthropic’s New AI Tools Rival Microsoft Office, Sending Stock Lower

Microsoft stock fell Tuesday after Anthropic unveiled Claude Sheets, Claude Whiteboards, and Claude Data, a new AI tool suite that directly rivals Microsoft Office products. Anthropic announced the tools, which build spreadsheets, whiteboards, and dashboards alongside existing document and slide capabilities. Microsoft 365 generates significant revenue, with that segment's consumer and commercial cloud services revenue rising 16% last fiscal year. The decline adds to recent tech sector volatility, including last week's post-midterm selloff over potential data center regulation and this week's inflation data and concerns about Nvidia CEO Jensen Huang's affair and AI chipmaker trajectory.
