Anthropic's Series G funding round valued the company at $380 billion post-money, more than double its previous Series F valuation of $183 billion. For cofounders holding equity stakes, this valuation increase significantly amplifies the theoretical value of their ownership positions. However, it's important to note that valuations represent what investors are willing to pay for new shares in a funding round, not necessarily the liquid net worth of founders. Founders cannot typically convert these paper gains into cash unless they sell shares, which is often restricted during the company's private stage. The valuation reflects investor confidence in the company's growth trajectory and market position rather than immediate wealth realization.

Anthropic has strategically positioned itself as an enterprise-focused AI company, which investors view as a more profitable business model than consumer-oriented approaches. The company's annual revenue run-rate has reached $14 billion, with customers spending over $100,000 annually increasing sevenfold in the past year. Eight of the Fortune 10 companies are now Claude customers, and over 500 customers spend more than $1 million annually with Anthropic. Wall Street investors show preference for Anthropic and Google due to their strong enterprise adoption narratives, viewing them as having more sustainable, higher-margin revenue streams compared to OpenAI and xAI, which are perceived as more consumer-oriented and potentially lower-profit models.
