Kim Joo-yeon, a researcher at Mirae Asset Securities, analyzed, “The top two semiconductors in the domestic stock market are showing weakness as they digest the ‘bubble theory’ caused by Open AI.”
According to the Financial Times (FT) and CNN last week, OpenAI recently announced to investors that its annualized sales were approaching $50 billion as of the end of September. The controversy over overheating of AI investment seems to have reignited when a figure was presented that was 29% lower than the initially reported sales volume of Open AI of $70 billion.
