OpenAI's valuation of $852 billion is facing scrutiny from investors as the company shifts its focus to the enterprise market. The company raised $122 billion in a recent funding round, marking one of the largest in Silicon Valley history, while redrawing its product roadmap twice in six months due to competitive threats.

OpenAI shares are nearly unsellable on secondary markets as institutional investors seek to unload $600 million in holdings. In contrast, demand for Anthropic equity has surged, valuing the company at approximately $600 billion, driven by its focus on profitable enterprise clients.

Anthropic has raised $30 billion in Series G funding, achieving a post-money valuation of $380 billion. The funding round was led by GIC and Coatue, with participation from notable investors including D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, and MGX, aimed at advancing research, product development, and infrastructure in enterprise AI and coding.
