When will Anthropic go public? Here’s what to know about the IPO timeline.

Anthropic has taken a procedural step toward a public listing by filing its IPO paperwork on Monday. Under the timeline described, that filing allows the company to conduct its investor roadshow during the week of Nov. 9, with eligibility to go public as soon as the following week. The filing itself is a preparatory move rather than a completed listing; the roadshow is the period in which the company presents its business and financial case to prospective institutional investors.

For markets, the development matters less for a single date than for what it signals: a high-profile artificial-intelligence firm moving through the standard sequence from confidential or public filing to investor marketing and, potentially, trading. Investors typically watch several markers along that path — the roadshow schedule, any updated disclosure in the filing, and confirmation of pricing terms — because each can shift expectations about timing and valuation.

The key point to watch is whether the process stays on the stated schedule. Roadshows can be accelerated, extended, or paused depending on investor demand and market conditions, so eligibility to list in the week after Nov. 9 is not a guarantee of when shares will actually begin trading.
