The rate at which large cloud providers convert revenue into physical infrastructure spending, sitting between capital markets and the procurement of servers, networking, and data center construction. It is gated by board-level return thresholds, depreciation cycles, and the capacity of suppliers to absorb large purchase commitments.
A sustained hot read means the largest cloud providers are still converting a rising share of revenue into physical infrastructure spending, so demand for servers, networking, and data-center build is being pulled through faster than a normal capital cycle. The read is capital spending measured against revenue, a demand-flow gauge: it shows how hard these buyers are committing capital, not whether that capacity has been energized.
