Microsoft Shifts Copilot to Usage-Based Pricing: Adoption Surges but Margin Questions Persist

What happened

Microsoft is transitioning its Copilot AI assistant from seat-based subscriptions to usage-based pricing, a move the company argues expands the addressable market and increases revenue per customer. According to the article, the number of Copilot customers consuming credits through usage-based billing grew over 75% last quarter, while daily active users rose fivefold year over year. This shift aligns with Microsoft's broader strategy to monetize AI through consumption models alongside premium seat upgrades, as already noted in the latest 10-Q. However, the master report maintains a WAIT rating because the stock trades at 27.6x earnings with Microsoft Cloud gross margin under pressure from heavy AI infrastructure spending. The new usage-based model could add revenue but may also raise variable costs, leaving margin trajectory unclear.

Implication

The shift to usage-based pricing for Copilot is consistent with Microsoft's effort to capture a larger share of AI software spending, and the reported growth in usage customers and daily users indicates strong product traction. However, usage-based revenue is typically less predictable than recurring seat licenses and may require higher infrastructure utilization, which could complicate gross margin recovery. The master report's key checkpoints remain Azure growth sustaining near 50% and Microsoft Cloud gross margin stabilizing around 65%, and this news does not directly address those drivers. At the current price of $530, the stock already discounts robust AI adoption, so incremental positive news may have limited impact. Investors should continue monitoring upcoming earnings for evidence that usage-based Copilot contributes to profitable growth without accelerating cloud cost increases.

Thesis delta

The news adds evidence that Copilot adoption is accelerating under the usage-based model, which supports the bull case for broader AI monetization. However, it does not alter the core concerns that the stock is richly valued and that Microsoft Cloud gross margin is still declining due to heavy capex. Therefore, the overall thesis remains WAIT, with the new information marginally positive but insufficient to warrant a rating change.
