Anthropic IPO Rumored for October as Speculation Mounts

Anthropic Edges Closer to IPO, October Debut Seen as Increasingly Likely

Artificial intelligence firm Anthropic is reportedly moving closer to its initial public offering (IPO), a listing anticipated to be one of the most closely watched technology debuts of 2026. The prevailing sentiment suggests that the company behind the AI model Claude could enter the public markets this fall, though several key factors and clarifications remain.

Prediction Markets Favor October Listing

While not a certainty, traders on prediction markets are heavily leaning towards an IPO occurring in October. Data from Polymarket indicates a mere 2% chance of Anthropic going public by September 15, with the probability rising to 10% by September 30. However, by October 31, the odds surge to 70%, and the market shows an 83% likelihood of an IPO by the end of the year. Recent trading sessions have seen a sharp increase in the probability assigned to an October listing, signaling growing confidence among users that the debut could indeed happen within that month.

Recent Reports Bolster IPO Speculation

This optimistic outlook is largely corroborated by recent reporting. A Wall Street Journal article indicated that Anthropic’s executives have been engaging with prospective investors to build confidence ahead of a potential IPO in September or early October.

Furthermore, Anthropic has taken a significant procedural step by confidentially filing for a U.S. IPO in June. This move grants the company flexibility to proceed once regulatory reviews and market conditions are favorable.

Ambitious Valuation Targets Emerge

Adding to the intrigue, some investors are reportedly targeting a valuation of $2 trillion or even higher for an October debut. Such a figure would more than double the $965 million post-money valuation Anthropic secured in its May funding round. However, the company has yet to publicly confirm either the IPO date or its valuation.

The extent to which IPO participants and public investors will embrace such a substantial valuation is likely to hinge on the confidence placed in Anthropic’s growth projections.

Aggressive Revenue Forecasts Underpin Valuation Hopes

Reuters reported that Anthropic is forecasting revenues between $190 billion and $200 billion for 2028. This stands in stark contrast to the $47 billion annualized revenue run rate disclosed in May. Bankers and investors are currently looking unusually far into the future to assess the company’s potential worth, attempting to account for its rapid growth and the substantial costs associated with training and operating advanced AI models.
