Anthropic opened its IPO roadshow on Nov. 10. Dario Amodei, the company's co-founder and CEO, set the week's pitch to investors in motion that day2. Investors covered every one of its 825 million shares within a day. By Nov. 11, orders ran several times past that number, Bloomberg reported, citing people close to the deal34.
The Book Fills Before the Price Does
Anthropic set a price range of $70 to $78 a share that Tuesday. The listing will trade on Nasdaq under the ticker ANT1. Pricing is planned for Nov. 18, with trading set to start Nov. 19.
It also set aside about 20 percent of the offering for retail buyers. A typical IPO keeps just 5 to 10 percent for them1. The 20 percent split alone shows how hard Wall Street is pushing to get in.

Anthropic ($ANT) has reportedly attracted several times more investor orders than shares available, according to Bloomberg, citing people familiar with the offering.

The account posts under the name Walter Bloomberg, carrying a disclaimer that separates it from Bloomberg News. It relayed what Bloomberg's own reporters were hearing from bankers. The book had cleared, and new orders kept landing in sizes usually reserved for anchor investors34.
A Target Cut From $2 Trillion, Twice
Anthropic's own ambitions started much higher. Bankers were discussing a $2 trillion valuation this fall, then backed off toward $1.5 trillion as a tech selloff rattled shareholders1. One investor called even $1.5 trillion a "stretch," CNBC reported.
The filed range settled lower still. At $78 a share, Anthropic is worth $1.405 trillion on a fully diluted basis. That is up from the $965 billion it carried in a May funding round1. Drop to $70, and the ceiling works out closer to $1.26 trillion.
Patrick Moorhead, CEO of Moor Insights & Strategy, ran his own numbers the morning the range came out. He pegged Anthropic's fully diluted value at $1.2 trillion to $1.3 trillion, below the company's own ceiling9. "Maybe, just maybe, they are pricing it to go crazy on IPO day," Moorhead wrote.

Fully diluted valuation, by whose estimate, as of Nov. 11, 2026
Each bar is one estimate of Anthropic's value: the magenta bar is SpaceX's own June valuation for scale, the blue bar is Anthropic's ceiling from its own filed price range, and the gray bar is Patrick Moorhead's independent calculation.
SpaceX's valuation and Moorhead's estimate may rest on a different share count than Anthropic's own fully diluted figure, so each bar is best read on its own.

The numbers behind this chart
| Item | Value |
|---|---|
| SpaceX's June IPO | $1.77T |
| Anthropic's filed ceiling | $1.41T |
| Moorhead's independent estimate | $1.25T |
SpaceX set the bar five months earlier. It priced its own record IPO at $135 a share on June 3. The sale raised $75 billion and valued the rocket maker at $1.77 trillion5. Anthropic's ceiling sits $365 billion under that number.
Anthropic is closing part of the gap a different way. Seven of its own suppliers and customers agreed to buy $26 billion of stock at the IPO price, alongside the public offering3. The group includes Nvidia, Microsoft, Google, AMD, Broadcom, Micron and TSMC. Add that to the $64.35 billion the public shares could raise, and the combined haul tops $90 billion, ahead of SpaceX's single raise1.
Anthropic needs a $26 billion side deal to pass SpaceX's $75 billion
Total dollars raised, by offering, as of Nov. 11, 2026
Each bar is one company's raise. SpaceX's bar is one public offering. Anthropic's bar stacks its public shares under its private placement, the combination it needs to clear SpaceX's total.
SpaceX raised its $75 billion through public shares alone. Anthropic's total only passes that figure once its $26 billion private placement is added to the public offering.

The Case For: Sentiment Is the Trade
Kevin Rippey covers technology stocks at Evercore ISI. He told CNBC the deal matters for reasons beyond Anthropic's own books.
"Sentiment around the frontier is the core driver of the AI trade set," Rippey said. "That is where I think things begin and end over the last two weeks"8.
A clean debut, in his reading, sends one message to every investor holding an AI stock. The frontier labs still earn the premium markets have paid them. He called the setup into December "quite bullish" if the offering lands well8.
The Case Against: A Peak Before a Fall
Jack Selby reads the same order book and sees a warning. He is a managing partner at Peter Thiel's family office and runs the venture firm Copper Sky.
"An underperforming Anthropic IPO has to be a very prominent player in what will be a pretty massive correction in the market with respect to AI," Selby told Bloomberg Television6. He added a sharper line about what comes after: a weak debut would hit hardest once early lockups expire.
Selby's numbers back the warning. He says more than 80 percent of Anthropic's revenue resets to zero each quarter. The reset leaves the company exposed every time a rival ships a cheaper model6. "It's a real business, but the business is still in its early innings and the idea that it is a trillion-dollar business seems exceptionally far-fetched," Selby said.
History gives his case some cover. A review of past deals found Klarna and StubHub both closed below their offering price despite heavy oversubscription7. Cerebras, SpaceX and Jersey Mike's each drew book coverage of four to twenty times their shares, the same review found. Full coverage, on this count, settles little about the first trading day.
What to do
Read Anthropic's own filing before the shares price on Nov. 18. Compare the $1.405 trillion ceiling against Moorhead's independent $1.2 trillion to $1.3 trillion estimate, and decide which number you would pay. Treat the oversubscribed book as a sign of demand alone, separate from whatever case you make for the price itself.
Watch where ANT opens against that range on Nov. 19. A price near the top backs Rippey's reading, while a quiet open, or a slide in the weeks after, backs Selby's instead.
By the numbers
- 825 million: Shares in Anthropic's combined public offering, priced at $70 to $78 each1.
- $64.35 billion: Proceeds Anthropic could net at the top of that range1.
- $1.405 trillion: Anthropic's fully diluted valuation ceiling, up from $965 billion in May1.
- 20 percent: The share of the offering set aside for retail buyers, versus a typical 5 to 10 percent1.
- $75 billion: What SpaceX raised in its own record IPO on June 11, valuing it at $1.77 trillion5.
- 80 percent: The share of Anthropic's revenue Jack Selby says resets to zero every quarter6.
- $26 billion: The private placement seven of Anthropic's own suppliers agreed to buy alongside the public shares3.
What to watch
Nasdaq opens ANT for trading on Nov. 19. A price that holds above the $78 ceiling through its first week would back Rippey's reading of sentiment over math.
Watch the lockup calendar next. Selby's sharpest warning lands weeks later, once insiders can finally sell.
