Key Highlights
- Microsoft unveiled Copilot Cowork, leveraging Anthropic’s Claude Cowork technology, designed for Microsoft 365 enterprise customers
- The solution automates tasks including presentation creation, Excel data management, and meeting coordination with minimal human oversight
- MSFT shares have declined 15% year-to-date, with an additional 9% drop in February after Anthropic’s initial Claude Cowork release
- Microsoft now incorporates Claude Sonnet models into M365 Copilot, expanding beyond exclusive use of OpenAI’s GPT models
- Microsoft 365 Copilot paid seats expanded 160% year-over-year during the latest reporting period
Microsoft unveiled Copilot Cowork on Monday, an AI agent solution developed through partnership with Anthropic. This offering integrates Claude Cowork’s autonomous features directly within the Microsoft 365 platform.
The solution automates presentation creation, fills Excel spreadsheets with data, and coordinates meeting schedules via email — requiring little human intervention. Testing is underway, with early-access enterprise users receiving availability later this month.
Microsoft emphasized its security infrastructure during the launch. Copilot Cowork runs entirely through cloud architecture, contrasting with Claude Cowork’s local device operation.
“We work only in a cloud environment and we work only on behalf of the user. So you know exactly what information it has access to,” said Jared Spataro, who leads Microsoft’s AI-at-Work efforts.
The release comes at a strategic moment. Anthropic’s initial Claude Cowork introduction on January 30 triggered widespread concern across software sector equities. Salesforce (CRM), ServiceNow (NOW), Intuit (INTU), and Thomson Reuters (TRI) experienced significant declines.
Microsoft shares also suffered. MSFT dropped nearly 9% during February after the Cowork announcement. The stock currently trades 15% lower since 2026 began.
Expanding AI Model Portfolio
Monday’s reveal signals an important evolution in Microsoft’s AI model approach. The company announced availability of Anthropic’s Claude Sonnet models for M365 Copilot users — a platform that previously utilized only OpenAI’s GPT models.
OpenAI represents approximately 45% of Microsoft’s cloud services contract backlog, creating concentration concerns among certain investors. Incorporating Anthropic provides Microsoft with enhanced strategic options.
Microsoft withheld specific pricing details for Copilot Cowork. The company indicated certain usage will be covered under its current $30-per-user, per-month M365 Copilot subscription, while additional usage can be acquired separately.
Corporate Deployment Momentum
Microsoft’s enterprise AI metrics demonstrate positive trajectory. Paid M365 Copilot seats expanded 160% year-over-year during the latest quarter, while daily active usage surged 10x.
Organizations implementing Copilot across more than 35,000 seats tripled year-over-year. Recent enterprise adopters include Mercedes-Benz, NASA, Fiserv, ING, and the US Department of the Interior.
Microsoft introduced additional agentic AI capabilities across Word, Excel, PowerPoint, and Outlook. The Microsoft Agent 365 governance platform reached general availability at $15 per user monthly.
The company packaged its complete offering — encompassing Entra, Copilot 365, and Agent 365 — into a consolidated Microsoft 365 E7 bundle priced at $99 per user per month.
Microsoft stock closed Friday at $408.96, declining 0.42%, with pre-market trading Monday morning showing further retreat of approximately 1.1% to $404.41.
