Anthropic Heads for Record IPO While Warning of Existential AI Risks

Anthropic, the AI safety-focused company behind Claude, filed for what could become history's largest initial public offering on October 26, 2026, as it warned investors that its own products pose potential catastrophic risks to humanity. The San Francisco startup's Securities and Exchange Commission filing revealed a company firing on all cylinders—generating $16.3 billion in revenue in the first six months of 2026, a 1,300% surge compared with the prior year—while simultaneously disclosing massive losses and existential concerns about artificial intelligence itself.
