Anthropic co-founder and president Daniela Amodei has entered the Forbes 400 list of America’s richest people with an estimated fortune of about $15.5 billion, becoming the youngest self-made female billionaire, according to the report. She oversees daily operations at the AI company, whose valuation is close to $1 trillion, and serves as chair of its board. Market expectations cited in the report put Anthropic’s annualized revenue at $65 billion by the end of July 2026, up from $1 billion at the start of 2025. Its valuation in private secondary markets was pushed as high as about $1.5 trillion. As Anthropic prepares for one of the largest technology IPOs in history, the value of equity held by its founders and employees has risen sharply, making several co-founders global billionaires.
