Citigroup: Global AI industry revenue will reach $975 billion by 2030.

According to the latest forecast from Citigroup, global artificial intelligence (AI) industry revenue is expected to climb to $975 billion by 2030, a significant jump from $43 billion in 2025, representing a compound annual growth rate (CAGR) of 86%.

This rapid growth reflects the accelerated adoption and commercialization of AI technologies by businesses, and is also driving hyperscale cloud service providers to increase infrastructure investment to meet growing market demand.

Last week, the four major US tech giants—Alphabet (Google's parent company), Meta (Facebook's parent company), Microsoft, and Amazon—announced significant increases in annual capital expenditures, focusing on expanding investments in semiconductor infrastructure and data center capacity to support the explosive growth in demand in the AI field.

Citigroup further estimates that the cumulative capital expenditures of major US cloud service providers alone will reach $4.4 trillion between 2026 and 2030.

Globally, total investment, including from sovereign wealth funds and other institutions, is expected to reach $7.75 trillion.
