On secondary share trading platforms, Anthropic has quietly flipped the AI power map—trading at roughly $1 trillion, overtaking OpenAI for the first time.
just got offered a $1.05T valuation on my anthropic shares from a very well known growth fund
That's not a small gap. And it didn't exist three months ago.
Besides revenue, the supply side is doing the heavy work pushing up these valuations. Anthropic employees and early investors have had very few chances to sell. When buyers pile in and almost nobody is selling, prices move fast. Glen Anderson of Rainmaker Securities told Business Insider that a $960 billion valuation—which would have been "unthinkable" a month earlier—was being snapped up within hours by competing buyers.
None of this means Anthropic is worth $1 trillion in any primary-market sense. Secondary trades are illiquid, minority positions with no board rights and no path to forced liquidity. The trillion-dollar figure reflects what a buyer will pay for a small stake, not what Anthropic could raise in a full funding round, and not necessarily what an IPO would be priced at.
