Key facts
- Anthropic released Claude Sheets, Claude Whiteboards and Claude Data, tools the report says rival Microsoft Office services.
- Anthropic said Claude can build spreadsheets, whiteboards and dashboards with a team, alongside its existing document and slide-deck abilities.
- Microsoft's consumer and commercial products and cloud services revenue in the segment containing Microsoft 365 rose 16% in the last fiscal year, per its 2026 investor letter.
- Anthropic began an IPO roadshow and aims to price the deal on November 18, according to Business Insider.
Microsoft shares dropped on Tuesday, November 10, 2026, pressured by Anthropic's release of a suite of AI tools that Business Insider described as rivals to Microsoft Office products. Anthropic rolled out Claude Sheets, Claude Whiteboards and Claude Data.
"Starting today, Claude can build spreadsheets, whiteboards, and dashboards with your team. These work with its existing abilities to create documents, slide decks, and designs," Anthropic said in a release on its website.
Microsoft 365 makes up a significant portion of Microsoft's total revenue, the report said, citing Microsoft's 2026 investor letter: consumer and commercial products and cloud services revenue in that segment rose 16% in the last fiscal year.
The report said the decline adds to pressure on the stock from volatility in the AI sector. It said tech stocks led a stock rout the previous week following the midterms, as investors feared Democrats could slow data center development, and that the sector was unsettled again as investors weighed hot inflation data and Nvidia CEO Jensen Huang's affairs and the future trajectory of the AI chipmaker.
Anthropic is proceeding with its IPO despite the volatility, beginning a roadshow and aiming to price the deal on November 18, the report said. It said Anthropic released a suite of tools earlier in 2026 that set off a sell-off in software-as-a-service stocks and a rerating of software companies seen as exposed to AI disruption.
