AWS Financial Model: Why Amazon Is Deliberately Sacrificing $115B in Free Cash Flow
This analysis is part of Amazon's AI Business Model Pivot , a deep dive by The Business Engineer.
Key Components
The Core Numbers (Q3 2025)
AWS revenue reached $132B annualized run rate (+20% YoYβfastest since 2022). CapEx surged to $150B+ projected for 2026 (+78% YoY).
The Deliberate FCF Sacrifice
Operating cash flow remains strong at $130.7B (+16% YoY). AWS margins are stable at 34.5%.
The Agent Product Economics
Where does CapEx convert to revenue? Connect: $1B ARR from 12B minutes of AI interactions. Trainium: Multi-billion-dollar business growing 150% QoQ.
The Unit Economics Shift
Old model: Revenue scales linearly with compute hours ($/hour). New model: Revenue scales with value per task βprice decoupled from compute, higher margins per transaction,…

Key Insight
Operating cash flow remains strong at $130.7B (+16% YoY). AWS margins are stable at 34.5%. The FCF compression comes entirely from the $115.9B TTM CapEx surge β3.8 GW of power capacity added, Project Rainier with 500K Trainium2 chips scaling to 1M, and server useful life reduced from 6 to 5 years ($700M 2025 operating income impact).
AWS revenue reached $132B annualized run rate (+20% YoYβfastest since 2022). CapEx surged to $150B+ projected for 2026 (+78% YoY). The committed backlog stands at $200B, with October deals exceeding all Q3 deal volume combined. TTM free cash flow compressed to $14.8B (-69% YoY).
