Will Anthropic Announce an IPO This Year? Odds Rise to 74% After Confidential Filing and November Target

Anthropic has not officially announced an IPO date or pricing, but it filed confidentially with the SEC, disclosed that in June, and Reuters reports it is targeting a November listing. On Oct 14, it presented third-quarter financials to institutional investors at its San Francisco headquarters, and Bloomberg reported quarterly revenue of $16.8 billion. Anthropic declined to comment on the figures.

On Kalshi's "Which Companies will officially announce an IPO this year?" market, the Anthropic contract rose from 70% to 74% over three days, a gain of 4 percentage points. That put it at 74% on Oct 16. The market resolves on an official announcement. A confidential filing and a reported November target do not settle it on their own, so the contract stays below certainty.

Investors Temper Valuation Expectations as the Wider US IPO Market Slows

The investor pushback concerns price, not whether the deal happens. Reuters reported on Oct 15 that investors are tempering their valuation expectations because revenue growth is slowing, according to people familiar with the matter. Earlier reporting put the potential valuation near $2 trillion, with a raise of up to $100 billion. That figure is still under negotiation and has not been set.

The deal is also moving forward with few peers. Bloomberg reported on Oct 15 that Anthropic "stands alone" while the rest of the US IPO market slows to a crawl amid rising interest rates. Oura postponed its own IPO, citing market uncertainty. Broadcom CEO Hock Tan warned that access to capital could become the biggest constraint for AI companies. CNN separately noted that CEO Dario Amodei recently called for an industry-wide slowdown over safety concerns. The company also faces a legal dispute over a supply-chain risk designation.

We could not establish that the broader slowdown caused the 4-point rise. The move coincides with the Oct 14 investor presentation and the reporting of a November target.

Anthropic's contract moved from 70% to 74% around the Oct 14 investor day, where the company presented Q3 financials.

What Could Confirm or Reverse Anthropic's IPO Odds Next

Three developments would confirm the move:

• A public S-1 filing
• An official announcement of timing or pricing
• A roadshow launch consistent with a November listing

Because Anthropic filed confidentially, a public S-1 would be the first official disclosure of its full financials. The sources reviewed report no specific date for that filing.

Three developments would reverse it:

• Reports that the timeline has slipped
• A valuation impasse between Anthropic and investors
• A postponed target, as the slowing revenue growth Reuters described feeds into pricing talks

Oura's postponement shows that issuers in this market are willing to delay. Live pricing sits on the Which Companies will officially announce an IPO this year? odds page. The next decisive signal is whether a public S-1 appears in time to support a November debut.
