Google Cloud revenue growth accelerated throughout FY2025, from +28% in Q1 to a remarkable +48% in Q4, the fastest growth rate among hyperscalers. Full-year revenue reached $58.7B (+36% YoY), with Q4 annualized run rate exceeding $70B.
The growth was primarily driven by AI workloads -- revenue from generative AI products grew nearly 400% YoY in Q4, and over 70% of existing Cloud customers now use Google's AI products. The $240B RPO backlog provides 3-4 years of revenue visibility at current run rates and more than doubled YoY. The number of billion-dollar deals closed in 2025 surpassed the previous three years combined, with landmark wins including Meta ($10B), Salesforce ($2.5B), ServiceNow ($1.2B), and the Anthropic TPU mega-deal worth tens of billions. Key risks include capacity constraints that CEO Pichai says will persist through 2026, and potential growth deceleration if the AI spending cycle moderates.

How much of the 48% Q4 growth was one-time deal timing vs sustainable acceleration?
How much of the 48% Q4 growth was one-time deal timing vs sustainable acceleration?
Google Cloud has been the primary market share gainer among hyperscalers, rising from 12% to 14% of the cloud infrastructure market over the past year per Synergy Research. AWS has steadily declined from ~33% in late 2021 to 28% in Q4 2025, while Azure plateaued at 20-21%.
The Big Three combined hold 63% of the $419B annual cloud infrastructure market. Google Cloud's 48% Q4 growth rate was double AWS's 24% and exceeded Azure's 39%, suggesting continued share gains ahead. The broader cloud market grew 30% YoY in Q4 2025, crossing $100B quarterly revenue for the first time in Q3. GenAI-specific cloud services are growing 140-180% YoY and now drive more than half of cloud market growth, creating a secular tailwind. The sovereign cloud sub-segment ($80B forecast for 2026) is a fast-growing niche where Google is investing heavily through partnerships with T-Systems, Thales, and government contracts.
AI workloads are the primary growth engine for Google Cloud, with revenue from generative AI products growing nearly 400% YoY in Q4 2025. Over 70% of existing Google Cloud customers now use Google's AI products, and Gemini API volume hit 85B requests in January 2026 (up 142% from March 2025).
Google's custom TPU silicon provides a structural cost advantage -- Trillium (TPU v6) offers up to 4x better performance per dollar vs NVIDIA H100, and Midjourney demonstrated a 67% cost reduction after migrating from NVIDIA to TPU v6e. The Anthropic TPU mega-deal (hundreds of thousands of Trillium TPUs scaling to 1M by 2027) represents tens of billions in committed revenue. The next-gen Ironwood (TPU v7) delivers 10x peak performance over v5p. AI agent adoption is accelerating with 52% of executives reporting production deployments. Enterprise AI adoption is deepening: over 120,000 enterprises use Gemini, Citi deployed Vertex AI to 150,000 employees, and 8M+ paid Gemini Enterprise seats have been sold.
Google Cloud's remaining performance obligations (RPO) reached $240B at end of Q4 2025, an extraordinary metric that more than doubled YoY and grew 55% sequentially from $155B in Q3. The sequential trajectory through 2025 was remarkable: Q2 $106B, Q3 $155B, Q4 $240B.
At the current ~$70B annualized revenue run rate, the backlog represents roughly 3.4 years of committed revenue, providing exceptional visibility. The backlog surge was driven by mega-deals: the number of billion-dollar deals in 2025 surpassed the previous three years combined. Key named deals include Meta ($10B/6 years), Salesforce ($2.5B/7 years), ServiceNow ($1.2B/5 years), Anthropic TPU mega-deal (tens of billions), and UK Ministry of Defence ($500M+). Existing customers outpaced initial commitments by 30%, indicating strong upsell dynamics. Government and sovereign cloud contracts (UK MOD, NATO, GSA Gemini for Government, FedRAMP expansion) add a durable revenue base with long contract durations.
