Anthropic’s confidential S-1 filing on June 1, 2026, and its active preparations for marketing an initial public offering as early as mid-October explain the market’s strong consensus that it will reach public markets ahead of OpenAI. Recent reports indicate Anthropic is finalizing a $15 billion credit facility and targeting a Nasdaq listing before the November midterms at a potential $2 trillion valuation, supported by its $965 billion private round and rapid revenue growth from Claude large language models. OpenAI, which filed one week later, has since signaled a likely 2027 timeline amid internal debates over achieving a $1 trillion valuation and caution following SpaceX’s volatile debut. Key near-term catalysts include Anthropic’s public prospectus release and any unexpected acceleration in OpenAI’s process, though regulatory reviews or market shifts could still introduce delays for either company.
