Anthropic IPO Filing Ignites AI Sentiment, Lifts Asia Tech Stocks Ahead of Earnings and Central Bank Decisions

Asian equity markets advanced sharply following the announcement that Anthropic, a prominent generative AI startup, has filed for an initial public offering. The move revived investor enthusiasm in the artificial intelligence sector, bolstering technology stocks across key Asian indices and adding momentum to global sentiment ahead of a week with high-profile corporate earnings and central bank policy decisions.

AI Optimism Drives Tech Rally

The surge in Asian markets was evident as South Korea’s KOSPI outperformed regional peers, rallying over 3% after paring some early gains. Leading chipmakers Samsung Electronics and SK Hynix climbed 4% and 6%, respectively. Japan’s Nikkei 225 gained 1.6%, while Tokyo-listed SoftBank shares jumped more than 5% and Advantest surged nearly 10%. The Philadelphia Semiconductor Index rose 3% overnight, its largest daily gain in over a month, reflecting renewed interest in companies supplying AI infrastructure and components, according to Investing.com.

Anthropic’s IPO filing disclosed rapid revenue growth alongside steep losses, highlighting both the commercial potential and the high capital costs associated with advancing generative AI. The move signaled that public markets remain receptive to AI-focused companies despite ongoing concerns about profitability and substantial infrastructure spending. This renewed appetite for AI-exposed equities was mirrored in US markets on Monday, as the S&P 500 rose 0.7% and the Nasdaq Composite 0.8%, both supported by demand for AI-related shares.

Regional Divergence and Macro Support

While most Asian markets participated in the rally, China’s Shanghai Composite and Shanghai Shenzhen CSI 300 both edged 0.2% lower, and Hong Kong’s Hang Seng fell 0.6%. Nonetheless, major chipmakers SMIC and Hua Hong Grace Semiconductor posted modest gains. In contrast, Australia’s S&P/ASX 200 rose 0.5%, while Singapore’s Straits Times Index slipped 0.2%. India’s Nifty 50 index added 0.1%.

Further support for the technology rally came from stronger-than-expected macroeconomic data in South Korea. Its third-quarter GDP grew 1.0% quarter-on-quarter, accelerating from 0.6% in the prior period and surpassing economist forecasts of 0.7%.

Key Risks and Focus Ahead

Attention now shifts to upcoming US technology megacap earnings, with Alphabet, Microsoft, and Amazon all scheduled to report this week. Investors are focused on whether spending on data centers, semiconductors, and computing infrastructure is translating into sufficient revenue and profitability to support current valuations, as reported by Investing.com.

Simultaneously, investors are bracing for monetary policy decisions from the US Federal Reserve, European Central Bank, and Bank of Japan. All three are widely expected to maintain interest rates, shifting focus to remarks from policymakers for guidance on the future path of borrowing costs. The path of rates remains central to risk appetite in the technology sector.

The AI rally has also faced pressure in October as investors questioned the sustainability of the investment boom, especially given elevated borrowing costs. Additionally, crude oil extended losses, providing some relief as diplomatic efforts in the Middle East raised hopes for reduced geopolitical tensions. Persistently high energy prices, however, could fuel inflation and complicate the outlook for central banks, potentially limiting prospects for monetary easing. Ongoing risks include potential disruptions to energy supply and the impact of global political developments on market volatility.
