The AI share of enterprise tech budgets is set to rise sharply worldwide

Global AI spending is set to become the primary driver of incremental enterprise tech spend growth, rising from $340 billion in 2025 to around $3 trillion by 2035—approaching 23% of total enterprise tech spend worldwide, up from under 4% today.

What you will learn:

• Year-on-year growth holds above 30% through 2028 as firms move from pilots to production.
• AI spending remains heavily concentrated in the US—~58% of the global total in 2025, still ~49% by 2035—even as China, India, and other emerging markets accelerate from a low base.
• Spending is concentrated in IT services, software, cloud, and AI-ready hardware, which together capture the bulk of AI-related outlays. IT services is forecast to reach roughly $1.1 trillion in AI-related spend by 2035, while devices grow fastest as enterprises build out the compute, networking, and edge hardware needed to deploy AI at scale.
• Spending is highly skewed toward knowledge-intensive sectors, with finance, professional services, and IT & programming each exceeding $40 billion in AI spend in 2025 and leading on AI intensity.
