Anthropic is reportedly starting its IPO roadshow next week, aiming to list before Thanksgiving
Anthropic reportedly starts its IPO roadshow next week and aims to list before Thanksgiving, with valuation talk cut from $2 trillion to $1.1–1.3 trillion.
Anthropic plans to kick off its IPO roadshow next week — the week of November 9 — and is aiming to list on Nasdaq before Thanksgiving on November 26, The Information first reported on November 6; the timetable is reported, not confirmed by the company. The Claude maker filed its S-1 publicly on October 26 and amended it on November 2, and the cover page still carries no price range. Meanwhile, the valuation institutional buyers are discussing has slid from roughly $2 trillion in September to $1.1–1.3 trillion, after the AI selloff that took the Nasdaq down 5.52% on November 5. This roadshow will double as a stress test for the whole sector’s valuation.
Key points
- Per The Information, the roadshow is set for the week of November 9, with a debut targeted before Thanksgiving (November 26); SEC rules on public filings make November 10 the earliest possible start date.
- Valuation talk has moved from about $2 trillion in September to $1.4–1.5 trillion after an October results review, to $1.2–1.3 trillion now, with some buyers pushing $1.1 trillion.
- On Kalshi, the odds of Anthropic completing its IPO this year fell to under 60% (per Huxiu); Polymarket’s equivalent contract for a listing by December 31 still traded at 88.2% on November 6.
Background
Anthropic arrives at this window from a position of strength that the market has spent two weeks repricing. In May the company raised privately at a $965 billion valuation, overtaking OpenAI as the most valuable AI company; when the S-1 went public on October 26, the framing was still “up to $2 trillion, raising as much as $100 billion.” Two things happened next. The midterm blue wave triggered an AI selloff: on November 5 the Philadelphia Semiconductor Index fell about 12.3%, its worst day since March 2020, and the Nasdaq dropped 5.52% — with fears that the new Congress could tighten up on AI data-center construction; Huxiu cites a UBS estimate that potential building pauses could affect about 30% of planned 2028 US data-center capacity. Enterprise demand cooled in parallel: Ramp’s data showed monthly growth in business AI token spending collapsing from 42% in July to 1.5% across August and September, right as Anthropic approached its IPO. Reuters’ November 5 exclusive tied the strands together under the headline that the AI backlash could threaten the listing window.
The facts
The numbers below can be checked against filings and cited reports; the timing and valuation figures are reported, not confirmed by Anthropic.
| Item | Figure | Source |
|---|---|---|
| S-1 public / amended | Oct 26 / Nov 2, no price range | FinanceFeeds, via EDGAR |
| Roadshow start | Week of Nov 9 (earliest Nov 10) | The Information; 15-day rule per StockTitan |
| Listing target | Before Thanksgiving, Nasdaq, ticker ANT | The Information; ticker per S-1 |
| Valuation talks | $1.2–1.3 trillion, some buyers at $1.1 trillion | Briefs Finance, Nov 6 |
| Raise size | $80–100 billion, reports differ | ITHome; Huxiu |
| Q3 revenue | ~$16.96 billion, +47% QoQ (Q2: $11.6 billion) | Huxiu, citing investor-day materials |
| Q3 operating loss | $567 million | FinanceFeeds, citing PYMNTS |
| Cash and short-term investments | ~$131.9 billion (Sept 30) | Huxiu |
| Compute commitments | ~$895.4 billion in purchase and lease obligations, ~$69.8 billion due by September 2027 | Huxiu |
| Underwriters | Goldman Sachs and Morgan Stanley lead, 22 banks | Amended S-1 cover |
One contrast in the financials explains most of the price pushback: Q3 revenue grew 47% quarter over quarter, down from 145% in Q2 — a deceleration that lines up with Ramp’s spending data. Against that stands $131.9 billion of cash, which means the company can afford to wait; the binding constraint is the ~$895.4 billion of compute commitments, $69.8 billion of which falls due within two years.
What others say
The signals from buyers, analysts and prediction markets do not agree. Reuters quoted potential investors, anonymously, balking at the roughly $1.5 trillion ask and wanting a lower entry price. HSBC’s chief multi-asset strategist Max Kettner told Bloomberg Radio that “around $1 trillion would be a more comfortable launch point,” said he did not want the headline “oh my god, it is a trillion dollar IPO,” and warned against a SpaceX-style “rip then dump.” Morningstar’s chief equity strategist Michael Field took the other side: the physical and reputational cost of delaying could hurt the valuation more than a lower price, and he expects Anthropic to list at a discount rather than postpone. Prediction markets read the same news differently: Kalshi priced the odds of a 2026 IPO completion under 60% (per Huxiu), while Polymarket’s contract for a listing by December 31 traded at 88.2% (per Crypto Briefing) — one pricing risk, the other pricing optimism. The peer comparison landed the same week: OpenAI closed the first $11 billion tranche of its round at a $1.25 trillion valuation, below its earlier $1.4 trillion target, and Huxiu counted a queue of postponed or withdrawn listings behind it — Switch, Nscale, SB Energy, Firmus, AirTrunk REIT. Talent moved too: Claude Code’s former product head Cat Wu宣布 and Anthropic’s first growth-marketing hire Austin Lau both left for OpenAI in early November, though neither report tied the exits to the IPO.
Our take
Our judgment: what matters here is not how much Anthropic raises but that this will be the first public-market price ever set for a frontier AI company. The $965 billion private round and the $2 trillion press expectations were never tested against open order books; if the $1.1–1.3 trillion talk holds, it becomes the anchor for everyone after — OpenAI included — and turns “are AI companies overpriced?” into a tradeable answer. For developers and procurement teams that depend on Claude, the short-term impact is small: $131.9 billion in cash means supply and roadmap are not funding-constrained. Longer term, quarterly disclosures will, for the first time, expose Anthropic’s real margins and its progress against those compute commitments. The honest catch: every date and valuation band in this piece comes from anonymous sources and paywalled reporting the company has not confirmed, and the S-1 still has no price range. As Briefs Finance notes, Cerebras and Figma both traded below their IPO prices — day-one pricing is neither a ceiling nor a floor.
What to watch
Dated checkpoints. Around November 10: whether the roadshow actually starts — the earliest day SEC rules allow. Days after: the price-range amendment on EDGAR, which FinanceFeeds calls “the single filing that moves the Anthropic IPO from reported to confirmed.” November 19–20: dates Fox Business floated as possible first trading days (second-hand, unverified). November 26: Thanksgiving, the hard deadline of this window. Unresolved: investors still have not seen stand-alone October figures; if volatility persists, both the raise and the price could shrink again.
