Anthropic could raise a new $50 billion round at a valuation of $850 billion to $900 billion, according to multiple sources. The company has received preemptive investor offers and is expected to decide at a May board meeting. Anthropic's annual revenue run rate has surpassed $30 billion, driven largely by its Claude Code and Cowork AI coding platforms, and is approaching $40 billion.

Why it matters: This mega-round would more than double Anthropic's valuation from $380 billion in February and match or exceed rival OpenAI's $122 billion round at $852 billion valuation. The deal exemplifies the capital-compression arc in foundation models, where hyperscaler-level capital is needed to sustain frontier-model leadership. It also updates the fastest-ARR-ramp pattern: Anthropic's revenue run rate nearly quadrupled from ~$9 billion at end-2025 to ~$40 billion, driven by coding use cases—a segment where AI CapEx is converting to revenue at unprecedented speed.

Grounded expert take: The preemptive investor frenzy and $5 billion commitments without CFO meetings signal that institutional capital sees Anthropic as a generational asset. However, capital-compression dynamics mean that returns for late-stage investors hinge on a successful IPO or continued market dominance in coding and enterprise AI. The round's size—matching OpenAI's—suggests the market is pricing in a duopoly at the frontier, with both labs spending aggressively on compute and talent. If Anthropic proceeds, it will be the largest private AI raise in history, putting pressure on rivals to match.
