5 Stats on Cloud Computing's Trillion-Dollar Breakout in 2026

Cloud computing's growth had already been steady for a decade — then AI workloads hit, and the curve got steeper.

The numbers

• $1.11 trillion — projected global cloud computing revenue in 2026, officially crossing the trillion-dollar mark.
• 21.3% growth — Gartner's forecast for public cloud end-user spending in 2026, reaching roughly $850 billion.
• $679 billion — global cloud infrastructure spend expected in 2026, a 28.89% jump from 2025 and the first year infrastructure spend alone tops half a trillion dollars.
• 35% year-over-year growth — the Q1 2026 cloud infrastructure spending rate, the fastest since Q4 2021.
• 19% — the share of total cloud spend now driven by AI workloads, up from just 8% in 2023, as AI infrastructure spending on cloud platforms grew 80.8%.
• 9 consecutive quarters of accelerating cloud infrastructure spend growth through Q1 2026, the longest such streak in years.

Why it matters

Cloud computing has effectively gotten a second growth engine bolted on: AI training and inference workloads are now nearly a fifth of all cloud spend and climbing fast. For fintech and payments infrastructure providers, that shift matters directly — cloud costs, capacity, and vendor leverage are all being reshaped by AI-driven demand, not by traditional enterprise migration anymore, and budgeting for compute is starting to look a lot more volatile than it used to.
