State: STRESSED (88% confidence), unchanged. Microsoft's Azure grew 48% while some third-party data-center capacity was delivered late, reducing near-term reported capex. Alphabet's Google Cloud grew 103%, with meaningful TPU-system sales, but cash capex exceeded operating cash flow. Vertiv's organic orders rose more than 100%; revenue, profitability and cash flow also improved. This is continued demand with differentiated architecture, deployment and capital conversion, not yet a broad hardware order cascade.

Microsoft operating cash flow was $58.000 billion in the September 2026 quarter. Microsoft cash after CapEx (OCF minus cash CapEx) was $18.633 billion in the September 2026 quarter. Alphabet operating cash flow was $42.290 billion in Q3 2026. Alphabet cash after CapEx (OCF minus cash CapEx) was -$9.065 billion in Q3 2026.

Expected versus actual: cloud growth and power/cooling supplier capture were stronger than a simple capex-slowdown equals demand-collapse thesis; Alphabet's second consecutive negative quarterly free cash flow is a company-level negative cash-conversion residual, not evidence of industry-wide supplier failure. Stop conditions are: persistent deployment/ROI deterioration that spreads into actual hardware order cuts, or unit-value/architecture deterioration combined with supplier margins, inventory and cash-conversion decline. Next watch Amazon earnings, delayed cloud capacity conversion, and supplier orders-to-cash. Sources in full Chinese report.
