Shares of chipmakers and their suppliers in South Korea and Japan jumped on Tuesday after Anthropic, the developer of the Claude artificial intelligence models, made its initial public offering filing public, reviving demand for AI-linked stocks that had been under pressure for weeks [1].
The San Francisco company filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission on Monday, October 26 [2]. The preliminary prospectus says Anthropic has applied to list its Class A common stock on the Nasdaq Global Select Market under the symbol "ANT," with Goldman Sachs and Morgan Stanley at the top of an underwriter list that also includes J.P. Morgan, Citigroup and Barclays [2]. The price range and the number of shares to be sold have not yet been set [2].
The filing gives investors their first detailed look at the company's finances. Revenue for the six months ended June 30 was about $16.3 billion, compared with roughly $1.16 billion in the same period of 2025 [2]. The operating loss narrowed to $693 million from about $2.1 billion a year earlier [2]. The reported net loss was far larger, at about $80.7 billion, which the prospectus attributes mainly to a $72.4 billion charge from the rising fair value of convertible notes, derivative liabilities and SAFEs rather than to day-to-day operations [2]. Yahoo Finance reported that the company was valued at $965 billion in May and that the listing is expected later this fall [3].
In Asia, the reaction was strongest among companies tied to AI hardware. South Korea's Kospi closed 3.1% higher at 5,638.34 after briefly rising more than 4%, while Japan's Nikkei 225 gained 1.7% to 63,268.37 [4]. SK Hynix rose 5.2% and Samsung Electronics added 4.2%, while in Tokyo chip-testing equipment maker Advantest climbed 9.6% and SoftBank Group gained 5% [4]. The Kospi had fallen 18.2% over the previous month, according to Fortune [1]. South Korea also reported that its economy grew at a better-than-expected 3.4% annual rate in the July-to-September quarter [4].
Chinese markets moved the other way. Hong Kong's Hang Seng fell 0.7% and the Shanghai Composite lost 1.3% [4]. Among mainland AI names, Semiconductor Manufacturing International Corp. fell 1.3% and AI processor designer Cambricon dropped 5.7% [1]. Alicia Garcia Herrero, chief economist for Asia Pacific at Natixis, told Fortune that Hong Kong and mainland markets "sit outside the main U.S. AI supply chain" [1]. Traders in China were also watching a closed-door Communist Party leadership meeting in Beijing for policy announcements [4].
The move in Asia followed a firmer session on Wall Street, where the S&P 500 rose 0.7% on Monday and the Nasdaq Composite gained 0.8%, with Nvidia up 2.4% after three straight losing weeks [4].
The listing matters for markets beyond Anthropic itself. AI stocks have been volatile in recent weeks as investors questioned the cost of borrowing to build data centers and buy chips [4]. A public Anthropic would report results every quarter, giving investors a regular reading on demand for frontier AI models and on the computing spending that feeds chip and memory makers. Gary Ng, a senior economist at Natixis, told Fortune that a convincing outlook could translate into more AI infrastructure spending and more sales for Japanese and South Korean semiconductor supply chains [1].
Looking ahead, SK Hynix reports third-quarter results on Wednesday and Samsung Electronics on Thursday, while Alphabet and Microsoft report Wednesday and Amazon on Thursday [4]. Investors will also watch for the price range and offering size in an amended Anthropic filing, which will indicate how the company is valued as it heads to market.
