Anthropic, a prominent player in the artificial intelligence sector, has confidentially filed for an initial public offering (IPO) in the United States, positioning itself ahead of its competitor, OpenAI. This strategic move not only signifies the rapid acceleration of Wall Street's AI boom but also serves as a test of investor interest in the burgeoning sector. Experts indicate that such confidential submissions allow companies to bolster their IPO preparations while safeguarding sensitive financial information. Kat Liu, Vice President at IPO research firm IPOX, noted that filing shortly after SpaceX enables Anthropic to tap into strong investor enthusiasm for AI and growth stocks, suggesting that its valuation ambitions are more modest compared to those of SpaceX. This IPO race underscores the increasing momentum behind AI investments.
