AI Profit Landscape: For Every $100 in Model Company Revenue, $35-40 Flows to Cloud Providers, Generating $10-20 in Operating Profit for Them

Barclays breaks down the AI industry profit chain: AI lab paid inference profit margins have surged from the low teens in 2025 to 50%-65%+, with API margins potentially exceeding 80%, driven by enterprise demand and agentic workflows. Business mix differences (API vs subscription-led) can result in gross margin gaps of up to 17 percentage points between different labs. Industry revenue is expected to grow from $7 billion in 2024 to $690 billion in 2028, with training cost share declining from 96% to 30%, and post-2028 self-built infrastructure projects could erode the market share of the three major cloud providers.
