Major investors are increasingly skeptical that Anthropic can proceed with its planned IPO at a valuation of approximately $1.5 trillion, according to The Wall Street Journal. The AI company had targeted a listing in the week before Thanksgiving, aiming to raise up to $100 billion. Three key investors participating in the offering indicated the valuation may need to be reduced, with one suggesting it could fall closer to $1 trillion, while others questioned whether Anthropic would postpone the IPO entirely. Anthropic executives and advisers are expected to meet in the coming days to reassess IPO plans amid the broader sell-off in AI-related stocks. Separately, OpenAI's latest funding round has secured only $11 billion so far — less than half of its original $30 billion target — at a $1.25 trillion valuation.
