AI capital expenditure reached $765 billion in 2026, surpassing oil and gas capex of $681 billion for the first time, with UBS projecting hyperscaler AI infrastructure spending will total roughly $4.1 trillion between 2026 and 2028.
Google, Meta, Microsoft, and Amazon lead with three-year projected totals of $938 billion, $683 billion, $672 billion, and $628 billion respectively, while all three major memory makers report their entire 2026 HBM output is already sold out. Bloomberg reported a divergence between rapidly falling AI model access costs and continued increases in the costs required to build and maintain AI infrastructure.
