Microsoft Copilot Hits 20M Paid Users as OpenAI Deal Restructured

Microsoft reported Wednesday that Copilot now has 20 million paid enterprise seats while simultaneously announcing a major restructuring of its exclusive OpenAI partnership. CEO Satya Nadella said during quarterly earnings that the company quadrupled organizations paying for over 50,000 Copilot seats, with Accenture signing the largest deal to date at 740,000 seats.

Copilot Usage Reaches Email-Level Engagement

According to TechCrunch, Copilot queries per user increased nearly 20% quarter-over-quarter, with weekly engagement now matching Outlook usage levels. “This is like a daily habit of intense usage,” Nadella said during the earnings call.

Major enterprises are scaling their Copilot deployments significantly. Bayer, Johnson & Johnson, Mercedes, and Roche each have more than 90,000 seats, while the Accenture deal announced this week represents Microsoft’s largest Copilot win to date.

The AI assistant, integrated into Microsoft 365 applications like Word, Excel, and Outlook, has faced skepticism about actual usage rates. However, Microsoft’s data suggests enterprise adoption is accelerating, with users treating Copilot as an essential productivity tool rather than an experimental feature.

OpenAI Partnership Loses Exclusivity

Microsoft and OpenAI announced Monday a sweeping overhaul of their partnership, dismantling key exclusivity provisions that have defined their relationship since 2019. According to VentureBeat, the amended agreement transforms what was once the most consequential exclusive technology alliance into a strategic but arm’s-length commercial relationship.

Under the new terms, Microsoft will no longer pay revenue share to OpenAI when customers access OpenAI models through Azure. OpenAI continues paying Microsoft a 20% revenue share through 2030, but this obligation now has a total cap. Microsoft retains licensing rights to OpenAI’s intellectual property through 2032, though this license is explicitly non-exclusive.

Critically, OpenAI can now serve all products to customers on any cloud provider, including Amazon Web Services and Google Cloud. This ends Microsoft’s exclusive cloud hosting arrangement that previously funneled all OpenAI enterprise customers through Azure.

Nadella Confident About Revised Deal Structure

When asked directly about the partnership’s financial impact, Nadella expressed confidence in the new arrangement. “We feel good about our partnership with OpenAI,” he told analysts, according to TechCrunch. “I’m always very focused on any partnership and ensuring that there’s a win-win construct at all times.”

Nadella emphasized that Microsoft retains access to OpenAI’s intellectual property without paying royalties. “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,” he said.

The CEO also noted that OpenAI remains a significant Microsoft customer beyond AI services. “They’re a large customer of ours, not just on the AI accelerator side, but also on all the other compute sides,” Nadella explained.

Azure AI Revenue Surpasses $37B Annual Run Rate

Microsoft reported that its AI business has reached an annual revenue run rate exceeding $37 billion, up 123% year-over-year. This figure represents the last full quarter under the previous exclusive OpenAI arrangement.

According to CNBC, Microsoft’s fiscal 2026 third quarter revenue rose 18% year-over-year to $82.89 billion, beating Wall Street consensus estimates. The company issued strong forecasts for Azure cloud growth, though stock reaction remained muted in extended trading.

The AI revenue milestone demonstrates Microsoft’s success in monetizing its early investments in generative AI, even as the partnership structure evolves. Revenue growth has accelerated since Copilot’s enterprise launch, with adoption spreading beyond early adopters to mainstream enterprise customers.

Multi-Cloud Strategy Emerges

The restructured partnership enables OpenAI to pursue multi-cloud distribution strategies previously blocked by Microsoft exclusivity. Amazon Web Services CEO Andy Jassy quickly announced new OpenAI integrations, with both companies’ executives conducting joint interviews about their collaboration.

This shift reflects broader industry trends toward multi-cloud flexibility rather than single-vendor lock-in. Enterprise customers increasingly demand choice in cloud providers, particularly for AI workloads that require specific performance characteristics or geographic distribution.

Microsoft’s willingness to sacrifice exclusivity suggests confidence in its ability to compete on Azure’s technical merits rather than contractual constraints. The company has invested heavily in AI infrastructure and tooling that extends beyond OpenAI models.

What This Means

Microsoft’s Copilot momentum validates the company’s bet on embedding AI directly into productivity workflows rather than offering standalone AI products. The 20 million paid seats and email-level engagement suggest enterprises view AI assistance as infrastructure rather than experimentation.

The OpenAI partnership restructuring, while ending exclusivity, positions Microsoft for a more competitive but potentially more profitable relationship. Eliminating revenue sharing payments while retaining IP access through 2032 could improve margins on AI services.

The shift toward multi-cloud AI distribution may actually benefit Microsoft by forcing the company to compete more aggressively on Azure’s technical capabilities. This competitive pressure could accelerate innovation in AI infrastructure and enterprise tooling.
