The artificial intelligence industry must generate $6 trillion in annual revenue by 2031 to justify surging capital investment in data center infrastructure, according to a new report from Bain & Company.
AI Industry Needs $6 Trillion in Annual Revenue by 2031 to Justify Data Center Investment, Bain Says
Annual global spending on AI infrastructure, which includes new facilities, GPU upgrades, memory, and networking equipment, could reach as much as $1.5 trillion by 2031. Bain notes that sustaining this level of investment would require an AI market approaching $6 trillion annually, assuming capital expenditures amount to approximately a quarter of industry revenue.
New product development is projected to be the largest revenue segment, contributing an estimated $4.2 trillion. This segment is expected to include innovations in search, advertising, autonomy, and physical AI. Enterprise productivity is estimated to require between $1 trillion and $1.4 trillion in revenue to support gains in areas such as software development, sales, marketing, and IT operations. Consumer-focused services, including subscriptions and advertising, are expected to contribute between $200 billion and $400 billion.
Data center sizes and costs are doubling approximately every 12 to 16 months. For example, Meta Platforms' Prometheus data center in Ohio, which had an estimated cost of $24 billion and 600MW capacity in 2025, is projected to cost up to $200 billion and reach 9GW capacity by 2030, according to data from Epoch AI.
The report highlights that while capacity building remains a primary focus, the critical economic question is whether enough value can be created to justify the unprecedented scale of investment. Challenges such as power grid capacity, securing GPUs, skilled labor shortages, and public regulation remain significant hurdles for the industry's growth.
