A day after Anthropic filed to go public, Asian stocks rose sharply on October 27, 2026. In a market report that day, Reuters wrote that South Korea's KOSPI climbed more than 4% in early trading, Japan's Nikkei rose 1.9%, the MSCI Asia-Pacific ex-Japan index gained 1.2%, and Nasdaq futures were up 0.4%. Investors linked the rally to the prospectus Anthropic had published the day before: the first-half revenue growth it disclosed made the market reassess how fast the AI industry can earn money.
Where the gains landed
On October 26, Anthropic filed an S-1 document with the U.S. Securities and Exchange Commission and said it planned to list on Nasdaq under the ticker ANT; the number of shares and the price range have not been set. First-half revenue was $16.286 billion, while the net loss was $80.748 billion, of which about $72.388 billion came from revaluing convertible notes rather than cash spent.
More than one company's story
U.S. chip stocks also rose overnight, with the Philadelphia Semiconductor Index up 2.8%, its biggest one-day jump in a month. The market read Meta's plan to raise up to $95 billion for AI infrastructure as the same logic continuing: spending on computing keeps growing, and suppliers' order expectations rise with it.
After the excitement, earnings season
This week brings results from Alphabet, Microsoft, and Amazon, among others, plus policy meetings at the Federal Reserve, the European Central Bank, and the Bank of Japan, where economists expect all three to hold rates steady. Anthony Saglimbene, chief market strategist at Ameriprise, cautioned that investors need to see demand broadening beyond these interconnected companies before aggressive capital spending can be read as durable business need. The filing lit the mood; earnings season has to answer whether the spending turns into lasting profit.
