Global spending on Infrastructure as a Service (IaaS) optimized for AI is projected to grow 56.5% in 2027, reaching $66.1 billion compared to $42.2 billion in 2026. That 2026 figure itself represents a 96.4% increase from 2025, underscoring the accelerating pace of investment in AI infrastructure.
The surge is driven by two primary forces: the computational demands of training large language models and the rapid adoption of AI across enterprise applications and workflows. As organizations scale their AI initiatives, they're pulling forward infrastructure spending to support both development and production workloads, making AI-optimized cloud services a critical competitive advantage.
