Where enterprise generative-AI budgets go
Enterprises spent $37 billion on generative AI in 2025, with coding the dominant departmental use case at roughly 55% of application-layer spend (Menlo Ventures). Coding has clean, measurable productivity outcomes and the shortest time-to-value of any enterprise generative-AI workload — running on top of an existing developer base, which makes per-seat ROI straightforward to justify.
| Department | Share of departmental AI spend |
|---|---|
| Coding / engineering | ~55% ($4.0B) |
| IT | ~10% |
| Marketing | ~9% |
| Customer success | ~9% |
| Design | ~7% |
| HR | ~5% |
Revenue and market
The commercial scale of generative AI is now significant. OpenAI reached roughly $25 billion in annualized revenue in early 2026 — about $2 billion per month, up from around $20 billion at the end of 2025 (Sacra). For the broader capital picture, see our enterprise AI spend coverage.
