AI Giant Anthropic Files for IPO, Shares to Trade as ANT on Nasdaq

This roundup covers business and economic developments. Anthropic publicly filed for an initial public offering Monday morning, submitting its S1 with the Securities and Exchange Commission and moving closer to becoming the first major frontier AI lab to list its shares. The offering is expected to serve as a key test of investor appetite for the technology. Anthropic shares will trade on Nasdaq under the ticker ANT, according to the filing. The listing could come as early as November. Revenue climbed sharply over the past year, the filing showed, while Anthropic reported a net loss of $80.7 billion for the first half of this year. Private investors valued the company at $965 billion earlier this year, according to the Associated Press. The filing lands amid heightened concerns about AI safety, following security breaches and warnings from executives, including Anthropic CEO Dario Amodei, about societal risks. Monday's document flagged potential uses of the technology for cyberattacks, biological weapons development and government mass surveillance. Anthropic said it considers explaining these risks to the world a personal responsibility, and that it has a duty to prevent or reduce risks arising from its AI models. The company added that it must work with governments and other industry participants to address risks across society. Anthropic submitted confidential paperwork to the SEC in early June without releasing additional details. Rival OpenAI filed confidentially to go public a week later; the timing of the ChatGPT developer's next step remains unclear. Anthropic's IPO could become the largest ever, surpassing the record set by Elon Musk's SpaceX last June, when SpaceX shares opened at $150. The NBA announced Monday that the league is partnering with prediction market companies Kalshi and Polymarket. Multiple states have sued both firms as they seek to establish regulatory authority over the companies.
