Mercor eyes $20B — read the AI 'revenue' number first

An AI company most of your customers have never heard of is about to be worth $20 billion. Mercor — a marketplace that supplies human experts to train and evaluate the frontier models everyone else builds on — is in talks to raise at a $20 billion valuation, roughly double where it sat nine months ago. The number worth studying isn't the valuation. It's the "$2 billion in revenue" underneath it.

What actually happened

Per TechCrunch, Mercor is in early talks for a new round at a $20 billion valuation — up from $10 billion when it raised $350 million in October 2025 — and has reportedly already received a term sheet. CEO Brendan Foody says the company crossed $2 billion in annualized revenue in June, a 100% jump in four months. Alongside the raise, Mercor said it's acquiring Deeptune, an AI-agent-training startup whose entire team is joining. Forbes and Bloomberg reported the same valuation talks the same day.

Now read the revenue line carefully. "$2 billion annualized" is a run-rate — a recent month multiplied out, not $2B booked over a year. And Mercor's model is a marketplace: it connects thousands of contract experts to AI labs that need training data and evaluations, which means a large share of that top line is pass-through — money that flows straight to the people doing the work, not margin Mercor keeps. (The exact take-rate isn't disclosed.) None of that makes Mercor a bad business. It makes the headline something other than what "$2 billion in revenue" sounds like.

Why it matters for your business

You're going to be sold on numbers like these. Every AI vendor pitching you — the model provider, the agent platform, the tool your SaaS just bolted on — will wave a valuation and a run-rate as proof they're safe to build on. Those aren't the same claim. A doubling valuation on an annualized top line, in a business where most of the money passes through to contractors, tells you the category is hot. It tells you very little about whether that vendor will still exist, at that price, in three years.

Our rule when we help a client pick an AI vendor: ignore the headline, read the unit economics. Ask what the revenue number actually measures — booked or run-rate, gross or net — where the margin lives, and what happens to your workflow if the vendor gets acquired, repriced, or runs out of runway. Mercor's rise makes a quieter point too: the "intelligence" in the models you rent rests on an army of paid human experts you never see. That's the real cost structure of AI, and it's worth remembering the next time a demo makes it look like magic.
