The question
What would make an AI investment number useful to someone planning capacity? Start with the boundary of the number. A supplier reports revenue, a buyer reports investment, and an operator reports service. Their records can describe the same chain without measuring the same event.

Our AI revenue ladder follows Microsoft's FY2025 Q4 disclosure.

The bottleneck after the chip supplies the physical counterpart. Power connection, commissioning and commercial use are different milestones. The energy reading guide places those milestones within system demand and financing.

A question for your work
Choose one capacity assumption in a plan you use. What document would establish that the capacity is available, and which date does the plan currently use instead?
