Anthropic IPO Shuts Out China and Hong Kong Investors as U.S. Defense Rules Bite
Anthropic’s blockbuster stock market debut is closed to institutional investors in mainland China and Hong Kong, Bloomberg reported on Friday, with banks handling the offering refusing their orders under U.S. defense-trade rules — even as demand for the shares runs about six times the supply on offer.
Several U.S. banks involved in the deal have either refused to accept orders from buyers in those regions or told them that securing an allocation is highly unlikely, according to people familiar with the matter cited by Bloomberg. The restrictions stem in part from the U.S. International Traffic in Arms Regulations, known as ITAR, which govern the export and trade of defense-related technologies. Anthropic did not respond to a request for comment.
The exclusion is striking because the offering is otherwise one of the most sought-after listings in history. Anthropic is selling 825 million Class A shares at $70 to $78 each, a deal that could raise up to $64.4 billion in the public offering alone, with a further $26 billion in a concurrent private placement. At the top of the range, the company would be valued at about $1.4 trillion on a fully diluted basis. Reuters reported that orders reached roughly six times the available shares by Thursday evening, after the book was about twice covered on the first day of the roadshow on Tuesday.
What the banks are doing
The curbs are not written into the offering’s headline terms. Anthropic’s listing prospectus does not explicitly detail selling restrictions for mainland China and Hong Kong, according to the Bloomberg reporting. Instead, the limits are being applied by the syndicate banks themselves, which have declined orders or cast doubt on allocations for investors based in the two regions.
China appears alongside nations such as Iran and North Korea on U.S. defense-trade control lists, and Anthropic noted in its filing that escalating U.S.-China tensions and federal scrutiny over exposure to Chinese state actors pose material risks to its business. The company builds Claude, the family of artificial intelligence models at the center of the offering, and frontier AI systems are increasingly treated by Washington as strategically sensitive technology.
Goldman Sachs and Morgan Stanley are leading the offering, with 20 other banks taking part. The Financial Times has reported that bankers are weighing pricing the shares above the filed range, which could lift the targeted valuation beyond $1.5 trillion.
Investors look for workarounds
Some investors in the affected regions are trying to find another way in. A family office tied to a Chinese technology founder has submitted an order using a trust registered in the British Virgin Islands, though it remains uncertain whether the bid will succeed, Bloomberg reported. Hong Kong-based institutions may still attempt to bid through offshore holding structures, though final allocation decisions rest with Anthropic and are unlikely to be clarified in formal written guidelines, according to sources quoted by Bloomberg.
The restrictions mirror the playbook used during Elon Musk’s $86.2 billion SpaceX initial public offering earlier this year, when syndicate banks were instructed to bar orders from mainland China and Hong Kong under the same ITAR rules. The parallel underlines how national security rules are now shaping who can own shares in the companies building frontier AI.
Why this matters
The exclusion is the clearest sign yet that the U.S.-China technology rivalry has moved from export controls on chips into the capital markets themselves. The same week Anthropic’s books filled up, Jensen Huang resigned as Nvidia’s chief executive amid a scandal over alleged Chinese ties and chip export controls — a reminder that Washington’s scrutiny of AI companies now extends from their supply chains to their boardrooms and their shareholder registers.

For American investors, the practical effect is a smaller pool of buyers competing for the shares. Bankers have told prospective investors that existing backers will be given priority in allocations, and that some would-be buyers will receive smaller stakes than they requested. Retail sentiment around the stock, expected to list next week, has trended “extremely bullish” on the Stocktwits platform over the past day.
The numbers behind the demand are formidable. Anthropic’s annualized revenue run rate reached $81 billion at the end of October, up from $65 billion at the end of July, and the company reported $33.2 billion in revenue for the first nine months of 2026. Bank models cited in coverage project revenue of roughly $52 billion to $53 billion for 2026, rising to $135 billion to $137 billion in 2027.
What happens next
Anthropic expects to set the final IPO price on Wednesday, November 18, with trading starting the following day on the Nasdaq Global Select Market under the ticker ANT. The terms, including the size of the demand and the final price, could still change before then.
The company has said it expects to price on November 18, and the Financial Times reported that bankers are exploring a price above the stated range that could lift the fully diluted valuation beyond $1.5 trillion. If demand holds, the listing would be the largest first-time share sale in history, ahead of the biggest offerings of the past two decades.
Whether the China and Hong Kong exclusion survives scrutiny is another open question. The restrictions were reported by Bloomberg citing people familiar with the matter, and neither Anthropic nor the lead banks have publicly confirmed the policy. What is confirmed is the demand: the order book was six times more orders than shares on offer, and the deal is on track to price next week with or without buyers from the two regions.
Frequently Asked Questions
Why are investors in China and Hong Kong being shut out of the Anthropic IPO?
Underwriting banks have declined or cast doubt on orders from institutional investors based in mainland China and Hong Kong, citing U.S. International Traffic in Arms Regulations in part, according to Bloomberg. The rules govern defense-related technologies, and frontier AI is increasingly treated by Washington as strategically sensitive.
Is the exclusion written into Anthropic’s prospectus?
No. The listing prospectus does not explicitly detail selling restrictions for mainland China and Hong Kong, according to the Bloomberg reporting. The limits are being applied by the syndicate banks handling the offering.
How big is the Anthropic IPO?
Anthropic is offering 825 million Class A shares at $70 to $78 each, which could raise up to $64.4 billion in the public offering, plus $26 billion in a concurrent private placement, for a total of up to $90.4 billion.

Anthropic’s debut was already set to be the largest IPO ever. The decision to keep investors in China and Hong Kong out of it shows that, in 2026, even the biggest capital markets event of the year is shaped by the U.S.-China rivalry — and by defense rules written long before artificial intelligence existed.
