Anthropic lands $25B mega round as Sequoia joins $350B valuation push

This round, if it closes at the reported $25 billion, would make Anthropic one of the most heavily capitalized private companies in history and firmly entrench it in the top tier of frontier labs alongside OpenAI and xAI. The step up from a $170 billion to a $350 billion valuation in just four months underscores how investors see frontier model training as a winner-takes-most market where scale, data and compute reinforce each other.

Strategically, Sequoia crossing its own internal red line to back all three major US frontier labs—OpenAI, xAI and now Anthropic—signals that traditional “pick one horse” VC discipline has broken down in the face of AGI-scale upside. Capital is concentrating around a very small set of players that can credibly spend tens of billions per year on compute and data centers. That concentration will make it even harder for second-tier labs to access the chips, power and talent needed to keep up.

For the broader race to AGI, a $25 billion war chest gives Anthropic years of runway to push Claude beyond coding and office automation towards more general, agentic behavior—while also funding safety, interpretability and evaluation research at unprecedented scale. It effectively guarantees that there will be at least two or three fully funded AGI contenders for the rest of the decade.
