Checked 11 November 2026. Anthropic has filed for an IPO, and the registration statement is not effective. The registration statement is not effective, so the filing range is the reference until the offer prices.
An Anthropic IPO analysis, Anthropic IPO date Polymarket, an Anthropic IPO date prediction, Anthropic IPO Kalshi, Anthropic IPO Polymarket and an Anthropic IPO prediction are expectations. They are not the prospectus.
What is not a prediction
- The range is the company’s estimate, not a prediction market.
- The absence of a company trading date is a fact about the announcement, not a forecast that the deal will slip.
- CNBC reported on 10 November 2026 that people familiar with the deal expected pricing on 18 November and trading on 19 November. Yahoo Finance the same day said the company had not announced a first day, and that reports pointed to 19 or 20 November. Those are reports. They are not in the roadshow announcement.
Scenarios, labelled as scenarios
- The offer prices inside $70 to $78 and lists as ANT. That still needs an effective registration and a Nasdaq listing.
- The range is cut or raised. Any price prediction published before that amendment is out of date on the day it happens.
- The timetable moves or the offer is withdrawn. The company has not promised a day.
- The first public price differs from the IPO price. There is no trading history to measure that gap.
Where the arguments come from
Public commentary leans on prospectus revenue of $17.0 billion in the quarter to 30 September 2026, up 1,127% year on year, and on a May 2026 company valuation reported at $965 billion. The cautious case is the one the prospectus makes room for: no public market yet, a public-benefit-corporation form, and a price that is still an estimate.
