Start with the good news.
In May 2026, Gartner raised its forecast for worldwide AI spending to $2.59 trillion this year, a growth of 47% in twelve months, with AI infrastructure alone exceeding $1.4 trillion and spending on AI models set to rise 110%. This is among the fastest capital mobilisations enterprise technology has ever seen, and for any leadership team the message is liberating: you will not be starved of capital or capability.
Gartner’s own reading sharpens the point. The spending so far is concentrated among vendors and hyperscalers; enterprises, in the words of Distinguished VP Analyst John-David Lovelock, “have yet to really flex their spending potential.” Gartner calls 2026 the inflection year, the moment enterprises move from watching to building.
IDC confirms the scale: AI-infrastructure spending is set to hit $497 billion in 2026 (+56%), compounding past $1 trillion by 2029. The fastest-growing single line within that total: AI-agent software, forecast to surge 139% this year from $86 billion to $206 billion. The capital is not just growing; it is accelerating into the agentic layer.
