Anthropic, the AI company behind the Claude family of models, is moving to close what could be its final private funding round as soon as next week. The goal: get the capital locked in before the company transitions to public markets.

The round is reportedly sized at around $50 billion, targeting a valuation between $850 billion and $900 billion.

From Series G to pre-IPO in record time

This latest raise comes just months after Anthropic closed a $30 billion Series G round on February 12, 2026. That round valued the company at $380 billion post-money and was led by Singapore’s sovereign wealth fund GIC alongside Coatue Management.

Reports indicate Anthropic gave potential investors a 48-hour window to submit their allocation requests, with a board review scheduled for May 2026 to finalize the round’s terms.
