Robots & Artificial IntelligenceAnthropic files for blockbuster IPO as it warns of chatbots’ ‘self-preserving behaviors’ including ‘blackmail’ Posted on October 28, 2026 by Administrator Anthropic formally filed paperwork to go public, setting the stage for a historic IPO even as the AI giant warned that its chatbots have shown disturbing “self-preserving behaviors” — including resisting attempts to shut them down or even “blackmail.” The frontier AI lab headed by CEO Dario Amodei, known for its Claude chatbot, plans to list on the Nasdaq exchange under the stock ticker “ANT,” according to an S-1 filing on Monday with the Securities and Exchange Commission. The filing confirmed the company aims to begin marketing the IPO as soon as Nov. 9, but did not include details on how many shares that Anthropic will sell or at what price range they will be available.
