Global Cloud Computing Spending Reaches $280 Billion in First Half of 2026

## Cloud Spend Accelerates Combined cloud infrastructure spending across Amazon Web Services, Microsoft Azure, and Google Cloud Platform reached $280 billion in the first half of 2026, according to data compiled from each company's quarterly earnings disclosures. That represents 31% year-over-year growth, the fastest pace since 2021, fueled primarily by demand for AI training and inference compute. ## AWS Leads, Azure Closes the Gap AWS remains the market share leader with approximately 33% of total cloud spending. Microsoft Azure holds 22% and is growing faster than AWS for the third consecutive year, driven by its OpenAI partnership and deep enterprise Microsoft 365 integration. Google Cloud holds 12% and is the fastest-growing of the three on a percentage basis at 42% year-over-year. ## The AI Increment AI workloads — GPU compute for training and inference, AI-specific managed services like Bedrock, Azure AI Studio, and Vertex AI, and AI-adjacent storage and networking — are estimated to account for approximately 40% of incremental H1 2026 revenue growth across the three hyperscalers, up from essentially zero in H1 2023. ## CapEx Surge All three companies are investing heavily. AWS announced $120 billion in 2026 capital expenditures. Microsoft has committed $80 billion. Google has guided to $75 billion. Combined, the three are on track to spend over $275 billion on data centers and networking infrastructure in 2026 alone — an amount that will take years to depreciate and represents a multi-year commitment to AI infrastructure.
