AI infrastructure alone accounts for more than half of total spending.
What's driving the AI market growth?
AI infrastructure — chips, servers, networking, and data centres. Infrastructure alone accounts for $1.37 trillion in 2026, more than half of total AI spending, with $401 billion in incremental spend added in a single year. AI services spending reaches $589 billion and AI software $452 billion.
How big is the AI vendor market specifically?
The underlying vendor market (hardware + software + services revenue) reached $375.93 billion in 2026, growing at a 26.6% CAGR toward $2.48 trillion by 2034 according to Fortune Business Insights. This is the addressable market for AI vendors — separate from the broader enterprise AI spending figure.
How does AI compare to other tech categories?
AI is now the dominant driver of IT spend. Morgan Stanley estimates AI-related investment accounts for around 25% of US GDP growth. Wall Street consensus for 2026 hyperscaler AI capital expenditure alone is $527 billion — larger than the entire global semiconductor market just a few years ago.
