By 2035, spending on Artificial Intelligence (AI)-related services and upsell opportunities in industry is expected to reach US$35 billion, up from US$3.1 billion today. Strong R&D investment is accelerating industrial AI adoption across manufacturing, with software and SaaS solutions leading growth over traditional automation. Among the four AI phases—perception, generative, agentic, and physical—the greatest market potential lies in Agentic AI (US$10.7 billion) and Generative AI (US$9.6 billion), while Physical AI (US$8 billion) represents an emerging high-growth frontier. Monetization strategies remain experimental across the industrial AI market, often centered on premium service tiers or modular add-ons. The most effective industrial AI deployments enhance human roles by shifting from supervision to autonomous, learning-based operation, paving the way for next-generation multi-agent and physical AI systems.
