In his Substack post "Just say no to Anthropic's IPO," Gary Marcus, noting he is not an investment advisor, argues against Anthropic's IPO at a reported valuation of up to $1.4 trillion, citing the company's lack of profit, nearly $900 billion in future liabilities, and growth slowing from 147% in Q2 to 47% in Q3 as tokenmaxxing fades and Chinese competitors rise. He replays posts quoting Reuters on Anthropic's retracted filing details aiming to raise $69.3 billion, Ed Zitron on slowing revenue and a looming liquidity crisis, and Roger, who warns Anthropic and OpenAI could go bankrupt without escaping their commitments.
