AfterQuery reportedly becomes Y Combinator’s fastest-ever unicorn, now valued at $3.2B

AfterQuery, an AI model-training startup, has reportedly raised new funding at a $3.2 billion valuation. The jump comes just five months after it announced a $30 million Series A that valued the company at $300 million.

The reported valuation surge highlights how quickly capital is flowing into AI infrastructure startups tied to model training. If accurate, AfterQuery’s rise suggests investors are still willing to price top AI picks aggressively despite broader scrutiny of startup valuations.
