# Anthropic files confidential S-1 for near-$1 trillion IPO

> Anthropic has quietly set up what could be one of the largest technology IPOs in history. The company confidentially filed its S-1 on June 1 at a $965 billion post-money valuation, closing in on the trillion-dollar mark, right after wrapping a $65 billion Series H round. The trajectory is steep even by AI standards. That Series H valued the company at $965 billion, up from $380 billion just three months earlier in March. Anthropic began in 2021 as a breakaway team of OpenAI researchers with no product and no revenue, and is now a serious candidate to go public at close to a trillion dollars. Share count and offer price are not set yet, and timing hinges on market conditions, so this is a starting gun rather than a finish line. But a filing at this scale, alongside a parallel move from OpenAI, signals investors are being asked to price the AI boom on the public markets, not just in private rounds.
