From $61.5B to $900B in twelve months: anatomy of a 15x re-rating
The single most consequential thing about this round is not the absolute number — it is the slope. In March 2025 Anthropic was valued at $61.5 billion at its Series E close [7]. In September 2025 the Series F priced the company at $183 billion [7]. By February 12, 2026, Series G landed at $380 billion post-money, becoming the second-largest venture funding deal of all time behind only OpenAI's 2025 $40 billion round [8]. Now, less than ninety days after that Series G, Bloomberg reports talks at a $900 billion-plus valuation [1]. That is a roughly 15x re-rating in twelve months on the same underlying company, and it has become a recurring talking point across the investor community.
The re-rating is being underwritten by a revenue line that is itself moving at an unusual cadence. Anthropic's annualized revenue run rate has surpassed $30 billion [12], and PYMNTS reports it is 'expected to soon surpass $45 billion, up from $9 billion at the end of 2025' [6]. That implies roughly an 80x revenue increase in three years and pulls the implied forward multiple down from headline-shocking to merely aggressive. The pricing question is therefore less 'is Anthropic worth $900 billion today?' and more 'is the $45 billion run rate durable enough to amortize a $900 billion entry price for late-stage allocators who need a 3-5x outcome from here?' That is a different — and harder — question than the one the Series E investors had to answer.
