Anthropic's IPO roadshow has been running since November 10, and on the morning of November 12 its public IPO page hit the top of Hacker News. The reaction splits three ways: traders on X passing along oversubscription reports, skeptics on Hacker News doing loss math, and a smaller group of Claude users who say they will buy anyway.
Here is what people are saying, with links to each post. X and Hacker News counts are as of early morning PT on November 12, before this post went live, and will change. This post is not investment advice.
The deal, in one paragraph
Per Anthropic's amended S-1 and CNBC, Anthropic is marketing 825 million shares at $70 to $78. Anthropic's IPO page says that, subject to regulatory clearance, the share price is expected to be set on November 18 (EST) and shares are expected to begin trading on Nasdaq under ANT on November 19 (EST). Seven companies, led by Google and Nvidia at $10 billion each, are buying $26 billion of stock in a separate private placement. We covered the filing terms in Anthropic Sets $70 to $78 IPO Range, $26B From Big Tech, and the first wave of reactions to the S-1 in our S-1 roundup.
X: oversubscribed, and maybe priced higher
The most shared posts on X were market wires, not opinions.
- @unusual_whales (Nov 10, 5:42 PM PT, about 1,340 likes): "BREAKING: Anthropic bankers prepare to increase IPO valuation to $1.5 trillion or more, per FT"
- @zerohedge (Nov 11, 5:15 AM PT, about 960 likes): "*ANTHROPIC MEGA-IPO IS SAID TO BE MULTIPLE TIMES OVERSUBSCRIBED"
- @DeItaone (Nov 11, 5:47 AM PT, about 680 likes) attributed the same report to Bloomberg, "citing people familiar with the offering."
- @unusual_whales (about 1,050 likes) listed the private placement buyers: Google and Nvidia at $10B each, AMD $2.5B, Broadcom, Micron and Microsoft at $1B each, TSMC $500M.
These are reports from people familiar with the deal, not filings. The final price is not set until Anthropic prices the deal, which its IPO page says is expected on November 18.
Prediction markets joined in. @Kalshi (about 1,480 likes, 1.6M views) posted: "BREAKING: 1 in 70 Americans worth over $100 million could be Anthropic employees after IPO". @unusual_whales cited Polymarket at a "46% chance that the valuation hits $1.5 trillion to $1.75 trillion."
@unusual_whales also posted a revenue-per-employee list "per YF" that puts Anthropic at "$6.6M+", second only to Nvidia at "$7.2M".
Hacker News: the loss math
The Hacker News thread on Anthropic's IPO page had 152 points and 173 comments. Most top comments were skeptical.
The most direct one came from p-e-w: "$23 billion quarterly net loss. Hundreds of billions in future liabilities. IPO valuation above $1 trillion. The lunatics are running the asylum."
A reply from juliie pushed back on the headline loss: "To be fair, that loss includes over $20b from instruments like convertible notes." The commenter argued those notes "will behave like equity, and just turn into stock" and dilute investors rather than cost Anthropic cash.
Another, HeavyStorm, asked: "What the hell is 15% adjusted margin?"
The moat question
The biggest sub-thread (31 replies) started with brainless: "There is a lot of value from LLMs but it is something that I can switch easily." The argument: most apps do not need frontier models, so Anthropic and OpenAI "will have to become more of the end user application stack."
mxschumacher replied that such a move "would mean that they have to compete heavily with their own largest customers." arbll disagreed: "In practice it does not happen because there is a lot of value in having someone else deal with a problem."
TrackerFF compared AI to "some sort of utility. Like electricity, internet, etc." simianwords answered: "A model is also clearly not fungible."
Is this the bubble test?
Yajirobe asked whether the IPO, with the Nvidia leadership story, will "finally pop the AI bubble." marginalia_nu said that was unlikely on its own: "Nothing pops because of an underperforming IPO." The same comment added that a flop "might affect the valuation of OpenAI."
small_model said: "I would wait for 2-3 quarters before investing, it will drop and there will likely be lock-ins to contend with." esskay expected a repeat of SpaceX: "high price, instant drop and a load of amateur investors wondering why they just lost a ton of money."
Who can actually buy
Retail access was a practical thread. Bloomberg reported that "Australian retail investors are able to buy shares." @WOLF_Financial cited Bloomberg on the oversubscription and wrote that Anthropic expects retail investors in the U.S. and other countries to get "up to 20% of the shares."
On Hacker News, yu3zhou4 found the Revolut page blocked from Poland, with a notice that it "can only be viewed by persons located in UK, Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Spain, and Sweden." Kwpolska said the US page redirected to an EU version. zhivota asked how to decide with one day between pricing and trading: "I'd like to try it but I've never bought an IPO before."
EcommerceFlow said it was "incredibly sad we had no avenue to invest in these companies until now." arionmiles replied: "It's called the Secondary Market."
The roadshow video itself
Amodei's claim in the roadshow video that major diseases could be gone within a decade drew its own backlash, which we covered in our disease-claim roundup. It came up again here. steveBK123 quoted a tweet that contrasted a biopharma CEO's "forward-looking statements" with an AI CEO's "We will cure all diseases in less than 10 years" and asked: "can we at least be a little more sober?" @GaryMarcus (about 180 likes) wrote that "Dario basically lied his ass off in the video.". That is Marcus's opinion. We did not find a public response from Anthropic to the post.
Others read the charts. @SequoiaMaple posted one slide and wrote: "it's like really trying not to be an exponential."
The fans
A minority defended the company. Jgrubb: "What an interesting flood of negative comments with nothing to say. This company has completely changed my career." fblp: "The economics of this are absurd," but "I use Claude everyday" and "I wish them the best for their IPO."
Bottom line
On X, the story is demand: oversubscription reports and talk of a higher price. On Hacker News, the story is doubt about losses, moats and whether retail buyers end up as exit liquidity. None of the reported demand figures are final until Anthropic prices the deal, which is expected on November 18. Trading is expected on November 19. This post is not investment advice.
