Microsoft Struggles to Sustain AI Growth Amid Evolving Market

Microsoft Corp. (MSFT) faces a persistent challenge under CEO Satya Nadella: adapting its business model to keep pace with rapid technological shifts. The company was an early mover in generative AI through its partnership with OpenAI, but it has yet to produce a standout AI model or application. The adoption of Copilot, its AI-powered productivity tool, remains relatively modest compared to Microsoft's vast user base. Currently, Microsoft has 30 million Copilot seats, while commercial Office 365 boasts over 450 million users. Copilot is priced at an additional $30 per user each month, a model that is becoming increasingly difficult to sustain as AI agents perform tasks requiring vastly different amounts of computing power.

In response, Microsoft is shifting to usage-based billing. Copilot Cowork, which handles larger productivity assignments, is an early example, with thousands of customers already paying based on consumption. GitHub Copilot offers a successful case study for this approach. User numbers surged to 50 million by July, up from 26 million last October, while sales growth accelerated by 60% sequentially after a pricing change aligned with computing demand.

For investors, the opportunity lies in broader AI adoption across Microsoft's customer base. However, the risk is that unpredictable usage costs could slow adoption, allowing competitors to capture more workloads. The next major event for Microsoft is its Windows and Surface event, where the company plans to detail how local AI could shape the future of PCs.
