Anthropic IPO Said to Bar China Bids; Filing Has 25 Markets

Institutional investors based in mainland China and Hong Kong have been excluded from placing orders in Anthropic’s IPO, Bloomberg News reported on Friday, citing people familiar with the matter. Several banks have either refused to take those orders or consider it unlikely that they could get allocations, the people said, and some of them said the constraints were partly due to the US International Traffic in Arms Regulations.

Anthropic’s own S-1/A lists selling notices for 25 markets, from Argentina to the United Kingdom, and the words Hong Kong appear 0 times in it, by our count. The exclusion lands on a book Bloomberg reported on 12 November at about six times the shares available: against the 825,000,000 shares on offer, that is about $346.5 billion to $386.1 billion of orders at the $70 to $78 range, by our arithmetic, about 4.0 to 4.5 times SpaceX’s $86.25 billion IPO.

Business Pill · IPO Float

A short explainer on IPO float, the share of a company sold in its listing. It teaches the general idea and does not discuss Anthropic’s offering.

Update, 13 November 2026: what the reported valuation target means per share. Anthropic is targeting a valuation of $1.25 trillion to $1.4 trillion in its IPO, The Information reported, and several investors it spoke to expect it to price above that range. On the fully diluted count our earlier pieces used, those values are $69.00 and $77.46 a share, about the filed $70 to $78 range; on the 13.09 billion shares the filing says will be outstanding they would take $96.11 to $107.89, by our arithmetic. Read what the $1.25 trillion to $1.4 trillion target means.

The key insight: As we read it, the reported exclusion matters less for the size of the book than for who is in it: Bloomberg says China- and Hong Kong-based institutions are being turned away from a book it put at about six times the shares, which is $346.5 billion to $386.1 billion of orders at the range, by our arithmetic, and the S-1/A lists selling notices for 25 markets, none of them Hong Kong.

Update (14 Nov): Taiwan’s Fubon Life plans to subscribe for up to $700 million of Anthropic IPO shares. Fubon Financial Holding announced on the evening of 13 November, on behalf of its unit Fubon Life, that the insurer will take part in the offering with a subscription cap of $700 million, about NT$23 billion, excluding commissions and related taxes and fees, Taiwan’s Central News Agency reported. The number of shares and the price will be announced once set. Fubon Life said it is investing life-insurance funds under Taiwan’s Insurance Act; Fubon Financial itself holds no Anthropic shares, the report said.

Taiwan sits outside the China and Hong Kong exclusion Bloomberg reported. At the $74 midpoint, the 825,000,000-share base deal is about $61.05 billion, so a full $700 million order would be about 1.1% of it (our arithmetic). The final number of shares Fubon Life receives has not been announced.

What Bloomberg Reported

Bloomberg’s report, published at 15:37 UTC and marked exclusive, says the exclusion is “highlighting the sensitivities around an industry both Washington and Beijing consider strategic”. It adds that “some prospective investors are continuing to pursue possible ways to bid”. We read the headline and the first two paragraphs; the rest of the article is behind Bloomberg’s paywall.

Headline relays on X from 15:37 UTC put it as “ANTHROPIC IPO IS SAID TO EXCLUDE CHINA, HK-BASED INVESTORS”. The exclusion covers institutional investors based in the two places, as Bloomberg words it; the part we read does not say how many investors or how much demand that covers.

Earlier on Friday, Bloomberg reported that if the share sale prices at the top of its marketed range on Nov. 18, the IPO and private placement would together raise $90.4 billion, “easily surpassing the $86.2 billion in Elon Musk’s SpaceX listing in June”, according to Bloomberg’s summary of its article.

Orders at about six times the 825,000,000 shares Anthropic offers, at the $70 and $78 ends of its range, again
Orders at about six times the 825,000,000 shares Anthropic offers, at the $70 and $78 ends of its range, against the largest IPOs so far. Six times is Bloomberg’s report, citing people familiar; the dollar values are our arithmetic. SpaceX and Alibaba from SEC filings; Aramco as reported by Reuters.

What Was Posted on X

Walter Bloomberg (@DeItaone) relayed the headline at 15:38 UTC on 13 November, a minute after Bloomberg News published its report that China- and Hong Kong-based institutional investors have been excluded from Anthropic’s IPO. The relay is a headline only; this piece relies on the opening of Bloomberg’s article and on Anthropic’s filing.

Unusual Whales posted at 15:17 UTC on 13 November that Anthropic’s IPO has drawn about six times the orders for the shares available, per Bloomberg, which first reported it on 12 November. This piece turns that multiple into dollars against the 825,000,000 shares in the S-1/A.

What the Filing Says About Arms Rules and China

The S-1/A filed on 10 November says Anthropic’s models may be controlled under the Commerce Department’s Export Administration Regulations “or, in more limited circumstances, under the International Traffic in Arms Regulations”. It adds: “In certain contexts, the provision of our models, platform, and applications may constitute export of defense articles or defense services subject to the ITAR”.

On China, the filing says “the U.S. government has increasingly scrutinized AI companies’ exposure to Chinese state actors”. A separate passage on a US data rule describes limits on transfers of covered data to partners, vendors, employees and “investors located in China or with other specified links to China”; that passage is about data transfers, not share sales.

The ITAR passages quoted here concern the export of Anthropic’s models. The link between those rules and the order book comes from Bloomberg’s sources, not from the filing.

25 Markets, and None Is Hong Kong

The underwriting chapter’s Selling Restrictions section carries notices for 25 jurisdictions, by our count: Argentina, Australia, Brazil, Chile, Colombia, Dubai, the European Economic Area, India, Indonesia, Israel, Malaysia, Mexico, New Zealand, Peru, the Philippines, Qatar, Saudi Arabia, Singapore, South Africa, South Korea, Switzerland, Taiwan, Thailand, the United Arab Emirates and the United Kingdom.

The words Hong Kong appear 0 times in the full S-1/A, by our search, and 0 times in the original S-1 of 26 October and the first amendment of 2 November. The five free writing prospectuses Anthropic filed on 11 and 12 November, covering its IPO website and its UK, Australian, European and Japanese materials, also contain 0 mentions.

Other recent IPO filings do carry such a notice. Nscale’s S-1 of 18 September and SB Energy’s amended S-1 of 21 September each have a section titled “Notice to Prospective Investors in Hong Kong”. SpaceX’s June prospectus, which also names the ITAR, has 0 mentions of Hong Kong.

A missing notice is not the same as a ban: these sections set out how underwriters may offer shares in each market. Bloomberg’s report is about orders from China- and Hong Kong-based institutions being turned away. We do not know why Hong Kong is not among the 25.

How many times the words Hong Kong appear in the full text of four IPO filings on SEC EDGAR, our count on 13 November 2026. Nscale’s and SB Energy’s filings each have a Hong Kong investor notice; Anthropic’s S-1/A has selling notices for 25 markets, none for Hong Kong.

The Six-Times Book in Dollars

Bloomberg’s 12 November report, as its first sentence was quoted on X, says the IPO “has drawn about six times the orders for the shares available”, citing people familiar with the matter; we covered it in our oversubscribed-book piece. Read against the 825,000,000 base shares, about six times is about 4.95 billion shares of orders: $346.5 billion at $70, $366.3 billion at the $74 midpoint and $386.1 billion at $78, by our arithmetic.

Orders beyond the base shares, five times 825,000,000, come to about $289 billion at $70 and about $322 billion at $78, by our arithmetic. The underwriters’ option adds up to 123,750,000 shares; with it, the full deal at $78 is $74.0 billion.

Against the largest IPOs so far, that book is about 4.0 to 4.5 times SpaceX’s $86.25 billion gross raise, from its SEC filings, and about 11.8 to 13.1 times Saudi Aramco’s $29.4 billion including its greenshoe, as Reuters reported. Alibaba raised $25.0 billion in 2014, including its underwriters’ option, from its SEC filings. The base deal itself, $57.75 billion to $64.35 billion, is about two times Aramco and 67% to 75% of SpaceX, by our arithmetic; our league table ranks them.

Bloomberg’s $90.4 billion is the base deal at $78 plus the $26.0 billion private placement, $90.35 billion by our arithmetic. The placement is sold to suppliers in a separate class of stock, covered in our placement piece.

The Structural Read

As we read the filing, the arms-rule risk is about Anthropic’s models: the S-1/A says some provision of its models may count as export of defense articles or defense services under the ITAR. Bloomberg’s sources say those rules were partly behind the constraints on the order book; the filing does not make that link itself.

As we read the selling notices, Anthropic’s list matches the shape of SpaceX’s June prospectus, which also names the ITAR and also has 0 mentions of Hong Kong, while Nscale’s and SB Energy’s September filings each carry a Hong Kong notice. We do not know why Hong Kong is left out.

Bloomberg News, 13 November 2026

“The constraints were partly due to the US International Traffic in Arms Regulations, which control the trade of defense products, some of them said”

Three Implications

FOR DEMAND About 4.95 billion shares of orders on Bloomberg’s about-six-times report, against 825,000,000 shares, so about $289 billion to $322 billion of orders sit beyond the base deal, by our arithmetic.

FOR THE INVESTOR BASE China- and Hong Kong-based institutions are excluded from placing orders, Bloomberg reports, citing people familiar; 25 markets have selling notices in the S-1/A.

FOR THE TIMELINE Pricing is expected on 18 November and trading on 19 November, per Anthropic’s IPO website filed with the SEC, five and six days after the Bloomberg report, by our arithmetic.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Capex Map & The State of AI Hyperscalers.

The framework records: “the capex race is no longer a corporate spending cycle. It is a sovereign-scale financing problem dressed in tech-company clothing”.

As we read it, a book reported at about six times an offering of up to $64.35 billion shows public equity markets taking part in that financing, with US arms-export rules reported as one reason some buyers are left out. The framework predates the IPO and does not discuss it.

What Is Not Established

Bloomberg’s sources are unnamed, and we read only the opening of its article. The part we read does not say how many investors were turned away, how much demand they represented, or whether the six-times figure counts orders that banks declined. It does not say whether six times is measured against the base shares or including the option; we used the base.

We did not see a comment from Anthropic or its banks in the part we read, and Anthropic was not contacted for this piece. Pricing is expected on 18 November and trading on 19 November, per Anthropic’s IPO website filed with the SEC; see how the Anthropic IPO works and our Anthropic IPO map.

The Bottom Line

Bloomberg reports, citing people familiar, that China- and Hong Kong-based institutions have been shut out of Anthropic’s IPO book, partly over US arms-export rules. The S-1/A names 25 markets for its selling notices, none of them Hong Kong, and a book of about six times the 825,000,000 shares would hold $346.5 billion to $386.1 billion of orders, by our arithmetic.
