Global AI Spending Surges Toward $2.59 Trillion By 2026 As Enterprises Flood The Market But ROI Remains Elusive

Global AI spending is surging toward $2.59 trillion by 2026 — a 47% year-over-year increase — as enterprises flood the market with agentic automation investments, but CIOs are struggling to prove ROI, with analysts warning that misalignment between AI initiatives and strategic business goals remains the critical obstacle.

• Gartner forecasts global AI spending to reach $2.59 trillion in 2026, marking a 47% year-over-year increase, with enterprises now entering the market in full force after spending was previously dominated by tech companies and hyperscalers.
• Enterprise adoption of agentic automation is driving much of the surge, pushing short-term AI model growth to 110% in 2026 and adding $6 billion in spending, while sectors like AI cybersecurity, AI models, and AI data are all expected to more than double.
• Despite the massive spending wave, CIOs are struggling to demonstrate clear ROI from AI investments, with analysts warning that the core issue lies not in the technology itself but in the failure to align AI initiatives with strategic business objectives.
