In a recent Gartner forecast, it was noted that global AI spending is projected to total nearly $1.5 trillion in 2025.According to John David Lovelock, VP Analyst at Gartner, “The forecast assumes continued investment in AI infrastructure expansion, as major hyperscalers continue to increase investments in data centers with AI-optimized hardware and GPUs to scale their services.”He added that the AI investment landscape is also expanding beyond traditional U.S. tech giants, including Chinese companies and new AI cloud providers. Furthermore, venture capital investment in AI providers is providing additional tailwinds for AI spending.Looking towards 2026, overall global AI spending is forecast to top $2 trillion, led in large part by AI being integrated into products such as smartphones and PCs as well as infrastructure.
