Amazon Web Services Posts $35.6 Billion in Q4 Revenue — Up 24% as AWS Adds 4 Gigawatts of Compute in 2025

Amazon.com filed its fourth-quarter 2025 earnings with the U.S. Securities and Exchange Commission on February 5, 2026, reporting that Amazon Web Services — the world’s largest cloud provider — generated $35.58 billion in revenue for the quarter, a 24% year-over-year increase that exceeded analyst expectations of $34.93 billion. AWS represented approximately 17% of Amazon’s total revenue for the quarter. AWS operating income reached $12.47 billion — above analyst consensus of $11.91 billion — and the operating margin within the division widened slightly to 35% from 34.6% in the third quarter, indicating improving profitability as AI workloads scale. Amazon CEO Andy Jassy said on the company’s earnings call that AWS added almost 4 gigawatts of computing capacity in 2025 — more than double what the entire business had when it was running at an $80 billion annual revenue run rate in 2022. During Q4 2025, AWS unveiled Nova Forge, a service that provides access to Amazon’s generative AI models during the training stage for advanced customisation, and announced a $38 billion spending commitment from OpenAI to use AWS infrastructure. Amazon has committed to spending approximately $200 billion in capital expenditure in 2026 — more than double the $125 billion spent in 2025 — the largest single-year capital investment plan of any company in American business history. AWS operates 38 cloud regions with over 100 Availability Zones across 27 countries and plans to open a Saudi Arabia region ($5.3 billion investment), a European Sovereign Cloud in Germany (€7.8 billion committed), and a Chile region ($4 billion-plus) in 2026.
