Asian stock markets surged on Tuesday, buoyed by renewed enthusiasm for artificial intelligence after Anthropic PBC filed for its highly anticipated initial public offering. The move lifted risk appetite across the region, with technology shares leading gains ahead of major tech earnings and central bank meetings this week.
According to Bloomberg, equity-index futures for Japan and South Korea pointed higher at the open, tracking solid overnight gains on Wall Street. The S&P 500 advanced 0.7% and the tech-heavy Nasdaq 100 rose 1.1%, while the Philadelphia Semiconductor Index jumped 2.8%, its largest single-day gain in over a month.
South Korea’s KOSPI index saw some of the strongest momentum, climbing as much as 4.4% in early trading. Shares of leading chipmakers Samsung Electronics Co. and SK Hynix Inc. each rose more than 5%, according to Bloomberg, as investors bet on increased demand for semiconductors driven by advances in AI technologies.
Japan’s Nikkei 225 Stock Average also posted robust gains, rising as much as 2.2%. Chip-related stocks were standouts, with Advantest Corp. and Sumco Corp. each surging more than 6% in early trading, reflecting heightened investor confidence in the sector following Anthropic’s IPO announcement.
However, not all Asian markets participated in the rally. China’s markets underperformed, with Hong Kong’s Hang Seng Index and mainland China’s CSI 300 both declining. Proactive Investors reported that the Shanghai Composite slipped 0.4%, while the Hang Seng Index was 0.2% higher in late trading, showing more muted reactions compared to the broader region.
The surge in Asian equities followed Anthropic’s filing of its S-1 registration statement, moving the company closer to becoming the first publicly traded firm focused primarily on developing advanced AI models. The IPO, expected to take place on the Nasdaq under the ticker “ANT”, could raise at least $100 billion and value the company at up to $2 trillion, according to XTB and other market sources.
Anthropic’s filing has been widely interpreted as a signal of strong investor demand for artificial intelligence, especially after weeks of uncertainty over the sustainability of the AI trade. The company, known for its Claude AI model, is seen as a bellwether for the sector and its public debut is attracting close scrutiny from global investors.
Broader market sentiment was also influenced by upcoming earnings from major US technology companies and the Federal Reserve’s rate decision later this week. Meta Platforms is reportedly seeking to raise as much as $95 billion in a separate equity offering to support its AI development, while chipmaker Broadcom has secured a $63 billion financing deal to supply chips for Anthropic, according to Bloomberg.
Why it matters
Anthropic’s IPO filing has injected fresh momentum into global equity markets, particularly in Asia, where technology and semiconductor stocks are heavily weighted. The sharp gains in South Korea’s KOSPI and Japan’s Nikkei 225 underscore the pivotal role of AI in driving investor sentiment and capital flows, especially as chipmakers like Samsung Electronics and Advantest Corp. benefit directly from the sector’s expansion.
The landmark IPO, which could value Anthropic at up to $2 trillion, marks a significant milestone for the artificial intelligence industry. According to XTB, the offering would be one of the largest in capital markets history, reflecting the scale of investor interest and the perceived transformative potential of AI technologies. The move also comes as other tech giants, such as Meta Platforms and Broadcom, ramp up their own AI investments, signaling an intensifying race for dominance in the sector.
With major central bank decisions and tech earnings on the horizon, the market’s reaction to Anthropic’s IPO highlights the growing interdependence between technology innovation and financial markets. As investors await further details on the IPO’s timing and pricing, the focus will remain on how the AI trade shapes broader market dynamics in the weeks ahead.
