Analysis
Anthropic is targeting a Nasdaq debut as early as the week of November 16 under ticker ANT, according to a Yahoo Finance breakdown of the company's amended S-1 published November 4 -- with the earliest possible pricing date set for November 13, the night before trading typically begins.
What changed since Pulse's last Anthropic IPO story
Pulse previously reported that Anthropic's compute bill hit $10 billion in the third quarter alone, consuming 58% of that quarter's revenue. The amended S-1 Yahoo reviewed extends the picture to the full nine months ended September 30: revenue grew 1,206% year-over-year to $33.2 billion cumulatively, consistent with the quarterly build Pulse covered last week.
The new filing also narrows the loss picture: Anthropic's operating loss for the nine months improved to $1.3 billion, down sharply from $5.2 billion over the same period in 2025, even as compute costs kept climbing in dollar terms.
“16." The company will list on the Nasdaq Global Select Market under ticker ANT.”
The IPO timeline, and what's still unconfirmed
Anthropic "hasn't announced a date for its first day of trading," per the Yahoo analysis, but is "aiming to debut as soon as the week of Nov. 16." The company will list on the Nasdaq Global Select Market under ticker ANT. Based on the pace of SpaceX's own recent IPO process, Yahoo Finance calculated Anthropic could debut as late as Wednesday, November 18, if it follows a similar timeline. Anthropic's shareholders, including CEO Dario Amodei and President Daniela Amodei, are among those who stand to find out what their stakes are worth once an offering size is set -- the amended S-1 Yahoo reviewed does not specify a valuation target, and Pulse is not reporting the unconfirmed valuation range some other outlets have floated pending confirmation from a source Pulse has verified directly.
The infrastructure bill behind the numbers
The same filing discloses $895.4 billion in long-term compute and infrastructure commitments, of which $69.8 billion is due within the next 12 months -- a figure that dwarfs the quarterly compute bill Pulse flagged last week and underscores how much of Anthropic's growth is pre-committed rather than optional.
Anthropic's venture-stage backers -- including Lightspeed Venture Partners, Menlo Ventures, Sequoia Capital and others across a half-decade of rounds, from a 2021 Series A to a reported $965 billion valuation in a May 2026 round -- are set to find out at IPO what those stakes are actually worth in public markets.
What to watch
The gap between a November 13 pricing date and an unconfirmed November 16-18 trading debut leaves roughly a week in which investor demand, not Anthropic's own disclosures, will set the final terms -- the same week Pulse will be watching for whether the compute-to-revenue ratio it reported last week shows up as a line item investors push back on in the roadshow.
That roadshow will also have to address a narrower customer base than most IPO investors are used to seeing at this scale, a risk factor the S-1 itself flags, per Yahoo's review. A business built on a handful of very large enterprise and API customers can grow revenue 1,206% year over year and still carry more concentration risk than a public-market investor base accustomed to diversified subscription revenue would normally tolerate -- a tension Anthropic's bankers will need to manage in investor meetings before pricing on November 13.
