Barclays: 35-40% of AI Revenue Goes to Cloud Giants

KEY FACTS

For every $100 in revenue, AI model companies pay $35 to $40 in compute fees to the three major cloud providers.
Cloud service providers earn $10 to $20 in operating profit from AI businesses, with operating margins reaching as high as 45%.
Paid inference margins for AI labs have surged from approximately 10% in 2025 to between 50% and 65% in 2026.
Inference margins for API businesses exceed 80%, significantly higher than subscription services, driving overall gross margin expansion.
After 2028, independent financing infrastructure is expected to rise, leading to a decline in cloud giants' share of the AI compute market.

PHYSIX OBSERVATION

The AI industry is undergoing a critical pivot from 'cash-burning training' to 'profitable inference.' Cloud vendors are collecting hefty tolls thanks to their compute monopolies, while model companies achieve financial health through high-margin API businesses. However, current profits may be inflated by accounting discrepancies and short-term supply-demand mismatches. As independent compute facilities come online after 2028, the profit distribution landscape between cloud giants and model developers could be reshaped; investors must look past reporting noise to understand the true unit economics.
