Anthropic submitted its S-1 IPO prospectus on October 26, 2026, aiming for a record $1.5 trillion to $2 trillion Nasdaq valuation despite an $80 billion H1 loss. The filing comes as hyperscalers face severe free cash flow constraints, with Amazon posting a $42.4 billion deficit and Microsoft planning $25 billion in debt sales. Amid tech stock sell-offs and delayed tech listings, investors increasingly question market liquidity and the long-term capital structure supporting aggressive AI expansion.
