Anthropic advances IPO plans as competitors pause public listings

What was once a crowded pipeline of high-profile US technology listings for the remainder of the year has dwindled to a single contender: artificial intelligence lab Anthropic.

Anthropic is pressing forward with plans for its initial public offering (IPO), currently targeting a mid-November debut following a public prospectus release. The firm is expected to begin formal investor roadshows during the week of 9 November, a slight delay from its initial mid-October target ahead of the US midterm elections.

The upcoming listing will serve as a crucial bellwether for institutional sentiment toward frontier AI developers. Industry analysts suggest Anthropic’s position within the generative AI market could command a valuation reaching up to $1.5 trillion (approx. R26.3 trillion).

Anthropic’s insistence on proceeding stands in stark contrast to the broader retreat across the tech sector. A resurgence in global interest rates and heightened market volatility have triggered sharp sell-offs in shares and debt linked to AI operators like CoreWeave, raising broader institutional questions surrounding capital expenditure sustainability.

A series of key industry issuers have postponed or abandoned planned listings:

  • Nscale and Switch: Data center operator Switch and infrastructure builder Nscale have pushed listing timelines back to evaluate market conditions and process regulatory feedback from the US Securities and Exchange Commission (SEC).
  • SB Energy, AirTrunk REIT, and Firmus: SoftBank-backed SB Energy, Blackstone-backed AirTrunk REIT, and Nvidia-backed Firmus have either paused or completely withdrawn their capital market offerings.
  • Oura: The smart-ring maker’s recent market debut generated muted participation among long-only institutional buyers, dampening appetite across secondary listings.

Despite ongoing market scrutiny regarding the massive capital required for data center buildouts and concerns surrounding open-source competition, institutional investors continue to view Anthropic as an essential primary asset for long-term artificial intelligence exposure. Competing issuers have reportedly stepped aside to avoid competing with Anthropic for institutional capital during its November roadshow.
