Microsoft reported Wednesday that its M365 Copilot now serves 20 million paid enterprise users, with quarterly engagement up 20% and weekly usage matching Outlook levels. The announcement came as CEO Satya Nadella revealed Microsoft’s AI business has reached a $37 billion annual revenue run rate, up 123% year-over-year.
“Weekly engagement is now at the same level as Outlook,” Nadella told analysts during the quarterly earnings call. “This is like a daily habit of intense usage.”
Enterprise Adoption Accelerates with Major Deals
Microsoft has quadrupled the number of companies purchasing over 50,000 Copilot seats, with enterprise giants leading adoption. Bayer, Johnson & Johnson, Mercedes, and Roche each maintain more than 90,000 seats, while Accenture signed Microsoft’s largest Copilot deal to date with over 740,000 seats.
The growth trajectory reflects broader enterprise acceptance of AI productivity tools integrated directly into Office applications. Copilot queries per user increased nearly 20% quarter-over-quarter, indicating sustained engagement beyond initial deployment phases.
According to TechCrunch, Nadella emphasized that Copilot operates independently of any single AI model, including OpenAI’s systems. “You now have access in chat to multiple models by default, with intelligent auto routing in agents with critique and counsel,” he explained.
Revised OpenAI Partnership Maintains Strategic Advantage
Nadella addressed analyst concerns about Microsoft’s revised OpenAI partnership, which ended the software giant’s exclusive access to OpenAI’s technology. Under the new agreement, Microsoft retains royalty-free access to OpenAI’s most advanced AI models through 2032 while no longer paying licensing fees.
“We have a frontier model, with all the IP rights that we will have access to all the way to ’32 and we fully plan to exploit it,” Nadella said, using the term “exploit” in its business sense of leveraging opportunities.
The partnership restructuring allows OpenAI to pursue deals with other cloud providers, including a recent exclusive arrangement with Amazon Web Services. However, Microsoft continues generating revenue from OpenAI as a customer for Azure compute services and maintains its equity stake in the AI company.
Agent 365 Launches to Address Shadow AI Risks
Microsoft moved Agent 365 from preview to general availability, positioning the platform as a unified control system for enterprise AI governance. The product addresses what Microsoft calls “shadow AI” — autonomous AI tools employees install without IT approval, creating new security and compliance risks.
According to VentureBeat, Agent 365 enables IT teams to observe and govern AI agents across Microsoft’s ecosystem, third-party cloud platforms like AWS Bedrock and Google Cloud, employee endpoints, and partner SaaS applications.
“Most enterprises are trying to figure out how to harness the potential of autonomous agents,” David Weston, Corporate Vice President of AI Security at Microsoft, told VentureBeat. The platform helps organizations balance AI innovation with security requirements as autonomous agents proliferate across enterprise environments.
Xbox Copilot Development Discontinued
Microsoft discontinued Xbox Copilot AI development as new Xbox CEO Asha Sharma reorganized the gaming division’s platform team. The decision affects both mobile and console versions of the gaming-focused AI assistant.

Sharma announced on X that Xbox is “winding down Copilot on mobile” and “will stop development of Copilot on console.” The move follows Sharma’s addition of executives from Microsoft’s CoreAI team to Xbox leadership, suggesting a strategic shift in gaming AI priorities.
The reorganization aims to help Xbox “move faster, deepen our connection with the community, and address friction for both players and developers,” according to Sharma’s statement.
Financial Performance Exceeds Expectations
Microsoft’s fiscal Q3 2026 revenue reached $82.89 billion, an 18% year-over-year increase that beat Wall Street’s $81.39 billion consensus estimate. CNBC reported that Azure cloud unit guidance remained strong despite ongoing investor concerns about software market dynamics.
The $37 billion AI revenue run rate represents Microsoft’s fastest-growing business segment, driven primarily by Azure AI services and Copilot subscriptions. Enterprise customers are increasingly integrating AI capabilities into core business processes, creating recurring revenue streams beyond traditional software licensing models.
Microsoft’s diversified AI approach, spanning productivity software, cloud infrastructure, and enterprise governance tools, positions the company to capture value across multiple AI adoption phases as organizations mature their artificial intelligence strategies.
What This Means
Microsoft’s Q3 results demonstrate that enterprise AI adoption has moved beyond experimentation to operational deployment at scale. The 20 million Copilot users represent genuine workplace integration, not trial usage, with engagement metrics matching core productivity tools like Outlook.
The revised OpenAI partnership actually strengthens Microsoft’s position by eliminating licensing costs while preserving access to frontier models through 2032. This arrangement provides cost predictability for Microsoft while allowing OpenAI to diversify its cloud partnerships — a win-win structure that reduces dependency risks for both companies.
Agent 365’s launch addresses a critical enterprise challenge as AI tools proliferate beyond centralized IT control. Organizations need governance frameworks to manage autonomous agents while enabling innovation, making Microsoft’s unified management platform strategically valuable as shadow AI becomes a mainstream enterprise security concern.
