AI company Anthropic (founded in 2021 by a team that left OpenAI) is now making about $3 billion a year in revenue, [1]reports Reuters (citing "two sources familiar with the matter.")

Products in the so-called codegen space have experienced major growth and adoption in recent months, often drawing on Anthropic's models.

Anthropic's valuation: $61.4 billion.

OpenAI's valuation: $300 billion.
