OpenAI rival Anthropic makes its IPO filing public as the race to dominate Wall Street’s AI trade heats up

Anthropic, the five-year-old company behind Claude, has made public its filing for an initial public offering after a confidential submission to the SEC in June, and plans to list on Nasdaq under ANT, though a debut is not guaranteed. Dario Amodei founded the company in 2021 with researchers who left OpenAI; businesses have spent heavily on Claude, with growth accelerating this year through Claude Code and models Fable 5 and Mythos 5. Anthropic faces competition from OpenAI and Google and criticism over AI safety, regulation and national security, including two disputes with Washington, and its listing would follow SpaceX’s $85.7 billion IPO.
