Microsoft earnings preview: Copilot reportedly at 50M users as BofA flags Azure growth and monetization

Microsoft reports this week into a market that has just heard Amazon say AWS is sold out through 2027. BofA's preview names two variables that matter most. The first is Azure's growth rate, as a proxy for AI demand Microsoft can actually serve. The second is Copilot monetization, as a proxy for whether AI features generate revenue beyond infrastructure rental.

Tech Insider reports Copilot has reached 50 million users, a milestone Microsoft has not formally confirmed. The figure will be read against coding-assistant rivals such as AWS's Kiro and Google's Gemini Code Assist. It will also be read against seat-based enterprise deployments like Uber's company-wide ChatGPT Work rollout announced this week.

The backdrop is heavy capex across hyperscalers. Meta raised 2026 guidance to $135-145B and Amazon to $220B. Investors are increasingly asking where the free cash flow goes, and the r/ValueInvesting and r/stocks threads this week reflect that strain.

What to watch on the call:

- Whether Microsoft quantifies Copilot paid seats rather than users.

- Capacity constraints, and whether Azure faces the same 'sold out' dynamic as AWS.

- Any update on short-lived GPU depreciation, a growing concern for analysts modeling AI returns.
