Anthropic Courts Investors for What Could Be History's Largest IPO

Anthropic, now valued at $965 billion, is actively meeting with potential investors as it targets a public market debut in September or early October — a listing that could surpass all prior IPOs in size. CEO Dario Amodei and other executives are conducting pre-IPO roadshow-style conversations, offering assurances about the company's growth trajectory and competitive moat as skeptical investors push back on mounting headwinds.

Investors have zeroed in on three main concerns: the rising competitiveness of cheaper Chinese AI systems, friction with the Trump administration, and a growing public backlash against data-center construction across the U.S. Anthropic executives have largely downplayed the China threat, arguing that users consistently gravitate toward the most capable models available — and that Chinese systems still lag top American counterparts by several months in raw capability.

The company's near-term growth story leans heavily on Claude Code, its AI coding tool that propelled Anthropic to a reported annualized revenue run-rate above $47 billion as of May. That momentum has continued, though the platform has experienced intermittent outages. Anthropic has also recently signed new computing partnerships with SpaceX and Google, signaling confidence in sustained infrastructure demand.

To broaden its narrative and soften AI's image problem, Anthropic told select investors it plans to expand aggressively into healthcare and biology — positioning those moves as both a growth lever and a way to counter the negative public sentiment surrounding the broader AI industry. The IPO's pricing will carry enormous symbolic weight: it will effectively set the benchmark for how markets value the top tier of AI developers, with trillions of dollars in AI infrastructure spending resting on continued demand growth.

Rival OpenAI is not expected to go public until next year at the earliest, leaving Anthropic to set the tone. The comparison point investors are watching closely is SpaceX, which crossed $2 trillion in market cap after its own IPO this year before experiencing a notable share pullback — a reminder that even blockbuster private-to-public transitions can be volatile.
