Anthropic IPO Slips to Pre-Thanksgiving Target at $2 Trillion

From October to November

Anthropic's long-anticipated stock market debut is still on, but the calendar has moved. The Claude maker is now aiming to list on the Nasdaq before the Nov. 26 Thanksgiving holiday, with bankers potentially launching the formal roadshow during the week of Nov. 9, according to Bloomberg reporting cited by Yahoo Finance.4 The company reportedly still intends to finish its debut by year-end at the latest.4

The framing of that shift varies. The same report calls the pre-Thanksgiving window a "compressed timeline" while also noting that investors had previously expected an October listing.4 Those two statements do not fit neatly together. A New York Times piece on venture data still described Anthropic as tracking an October 2026 listing.5 The most plausible reading is that October was the market's assumption rather than a committed date. November is now the working target, which amounts to a modest slip. Late-November timing also carries its own risk, because Wall Street activity tends to slow sharply around the holiday.4 Any further delay could push the deal into December or beyond.

The Oct. 14 Pitch and the Numbers

The first concrete step is a gathering for prospective investors at Anthropic's San Francisco headquarters on Oct. 14.24 Bidders have reportedly pegged a fair valuation at $1.8 trillion to $2 trillion.234 That is roughly double the $965 billion post-money valuation from Anthropic's Series H in May.2 It would also top SpaceX's $1.77 trillion listing in June, which would make this the largest IPO on record.3

The reported size of the raise has grown quickly. Estimates have moved from more than $20 billion in September to as much as $100 billion, with Morgan Stanley, Goldman Sachs and JPMorgan Chase said to be leading the deal.2 Some caution is warranted here. One analysis notes that the invitation details, the valuation range and the underwriter figures come from a Barchart contributor piece produced with automated tools and not confirmed by Anthropic.2 It also stresses that no senior Anthropic executive has publicly named a valuation target.2 The $2 trillion figure is what investors and bankers expect, not a price the company has set.

There is also a sequencing concern. Investors are hearing a trillion-dollar pitch before any public prospectus exists.2 Until an S-1 is filed, outsiders are judging the company on leaks and pre-IPO marketing.

The Bear Case

Not everyone is buying in. Independent research firm New Constructs called the offering "the most ridiculous IPO of 2026" and warned of an "unprecedented test of investor gullibility."1 The firm values Anthropic at roughly $150 billion, less than a tenth of the reported target.1 By its estimate, justifying a $2 trillion valuation would require Anthropic to earn about double Nvidia's trailing-year profit.1 It cites widening operating losses and the growing popularity of open-source models as reasons it sees no "viable business" at that price.1

A separate analysis points to a figure it considers more important than the headline valuation: about $518 billion in future cloud, compute and infrastructure obligations, nearly all of them non-cancellable.3 Commitments that large make revenue growth a necessity, not a bonus. Public shareholders would inherit those obligations whether or not demand for AI keeps rising.

A Split AI IPO Pipeline

The broader backdrop is mixed. AI captured 82.7% of U.S. venture deal value through the third quarter, the highest share on record, even as megarounds for OpenAI and Anthropic paused.5 Meanwhile, OpenAI is reportedly leaning toward delaying its listing to 2027 after SpaceX's volatile debut.5 The two leading AI labs are now on different paths to public markets, so there is no single AI listing wave to point to.5

Our Read

The slide from an assumed October to a pre-Thanksgiving target is not alarming on its own. Mega-IPOs rarely run on schedule, and Anthropic appears to be moving ahead. The more telling pattern is that valuation expectations and raise sizes keep climbing while the core financial disclosure is still missing.

The $1.8 trillion to $2 trillion range reflects investor enthusiasm. The $518 billion in fixed commitments and the operating losses are what the eventual prospectus will need to address.13 Given OpenAI's retreat and SpaceX's rocky trading, Anthropic's listing looks set to serve as a referendum on whether public markets will pay private-market prices for frontier AI. The November window leaves little room for another delay.
