Google Cloud generated $58.7B in FY2025 revenue (+36% YoY), with growth accelerating every quarter from +28% in Q1 to +48% in Q4. The Q4 annualized run rate exceeded $70B. Operating margins expanded dramatically from 3% in FY2023 to ~24% full-year average in FY2025, with Q4 reaching 30.1% -- approaching AWS's 35% benchmark.
Central question for this segment
Can Google Cloud sustain 40%+ growth into 2026 given capacity constraints, or will supply bottlenecks throttle growth to 30-35%?

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.
Key open question
How much of the 48% Q4 growth was one-time deal timing vs sustainable acceleration?
Google Cloud has established itself as a credible #2 challenger in the hyperscaler market, gaining share at the expense of both AWS and Azure. At 14% market share (up 2pp YoY), Google Cloud is the fastest-growing hyperscaler with 48% Q4 growth vs Azure's 39% and AWS's 24%.
The competitive landscape is shifting in Google Cloud's favor: AWS's share has declined 5pp since 2021, Azure has plateaued, and Google's AI-native positioning (custom TPUs, Gemini, Vertex AI) differentiates it in the fastest-growing market segment. However, competitive threats are real: CoreWeave and other neoclouds are growing rapidly in AI infrastructure, Oracle has become a high-growth tier-2 player, and Microsoft's deep OpenAI integration provides Azure with a strong AI narrative. Google Cloud's sovereign cloud strategy and pricing advantage (10-20% cheaper than AWS/Azure for equivalent workloads) provide additional competitive moats.
Key open question
What is the competitive threat from Microsoft's OpenAI integration depth vs Google's Gemini + Vertex AI?
Google Cloud's margin trajectory has been one of the most dramatic improvement stories in tech: from -62% operating margin in 2020 to 30.1% in Q4 2025. Full-year FY2025 operating income was ~$13.9B on ~24% average margin, a 950bps expansion from FY2024's 14.1%.
Q4's 30.1% margin is approaching AWS's 35% benchmark. The critical tension is whether this improvement is durable given the massive 2026 capex plan: Alphabet guided $175-185B in 2026 capex (nearly doubling from $91.4B in 2025), with ~60% going to servers and ~40% to data centers. FY2025 depreciation reached $21.1B (+38% YoY from $15.3B), and the 10-K explicitly warns 2026 depreciation growth is expected to accelerate. Assets not yet in service total $78.6B -- a leading indicator of the incoming depreciation wave. Uncommenced lease obligations of $58.5B and a $9.9B power purchase agreement add further cost commitments beyond reported capex.
Key open question
Is the 30.1% Q4 margin sustainable or will depreciation from $175-185B 2026 capex push margins back to low-20s? If $91.4B capex depreciates over 5-7 years, it adds roughly $13-18B per year to the depreciation base.
Alphabet entered a definitive agreement in March 2025 to acquire Wiz, a leading cloud security platform, for $32.0B in all-cash -- Alphabet's largest acquisition ever. Wiz is expected to become part of Google Cloud upon closing (expected 2026). The deal reflects Google Cloud's strategic push into cybersecurity, an area where Wiz has established itself as the fastest-growing cloud security vendor. Wiz was previously courted by Google in mid-2024 for approximately $23B but declined; the $32B price represents a significant premium.
Regulatory risk
Will DOJ or EC challenge the Wiz acquisition given ongoing antitrust proceedings against Alphabet? The deal's regulatory outcome is the single largest uncertainty.
