“And meanwhile, we sort of know that you have positive gross margins on inference alone of sort of 40, 50%, but you've got the cost of building the next model, and you don't know where the cost The cost will move, or the cost of the next model will move, and you also don't really know what the ROI on agentic coding is yet, and you don't know what the ROI on anything else would be.”

The claim, plainly

Artificial intelligence model providers have positive gross margins of approximately 40% to 50% on inference alone, excluding frontier model training costs.

Assessment

Benedict Evans's assertion that AI model providers generate positive gross margins of roughly 40% to 50% on inference alone (excluding frontier training and R&D costs) is well supported by leaked financial disclosures and industry analyst unit economics across 2025 and 2026. Leaked internal figures reported by The Information in late 2025 and early 2026 showed OpenAI's adjusted inference gross margin was 40% in 2024 and 33% in 2025 (targeting 46% to 52%+), with paid compute margins reaching ~70%, while Anthropic revised its 2025 non-training gross margin projection to 40%. Additionally, mid-2026 research from Barclays and SemiAnalysis estimated inference margins for frontier AI labs in the 50% to 65% range. Because industry data consistently clusters direct inference gross margins between 40% and 60%, the claim accurately reflects the prevailing unit economics.

Leaked OpenAI financial disclosures in early 2026 reported adjusted gross margins on inference (excluding frontier training) at 40% in 2024 and 33% in 2025, with internal projections rising to 52%–67%.
Anthropic internal financial projections disclosed in early 2026 budgeted its 2025 gross margin excluding training at 40% (revised down from 50%).
An August 2026 Barclays unit economics report estimated paid inference gross profit margins for AI labs at 50%–65% in 2026.
