Global AI Infrastructure Spending Projected to Reach $1.7 Trillion

Global data center spending is projected to reach $1.7 trillion by 2030, according to Dell'Oro Group. This surge is driven by leading AI companies increasing capital spending by 50% or more in 2026. Nvidia Corporation continues to dominate the GPU market, with cumulative purchase orders for its Blackwell and Rubin chips expected to exceed $1 trillion through 2027.

Cloud infrastructure services spending reached $110.9 billion in the fourth quarter of 2025, with a projected 27% growth in 2026. Amazon Web Services remains the market leader with a 32% share, while Alphabet Inc. and Microsoft Corporation reported year-over-year growth of 50% and 39%, respectively. To meet the demand for AI agents, AWS expects spending to reach $200 billion in 2026, while Alphabet Inc. guidance ranges between $175 billion and $185 billion.

Strategic infrastructure projects include Microsoft Corporation's planned data center in Saudi Arabia and a 15-year, $7 billion agreement between Hut 8, Fluidstack, and Anthropic to supply data center capacity. Nebius Group is also expanding its AI cloud infrastructure, targeting an annualized revenue run rate of $7 billion to $9 billion by the end of 2026 following a massive revenue jump in the fourth quarter.
