Last week, the AI sector of the US stock market experienced severe fluctuations amid market doubts. Prior to this, AI star varieties such as Oracle were under pressure due to concerns about whether the huge investment in funds could be transformed into profit, as well as controversies over financing models. The discussion about whether the "AI bubble is on the verge of bursting" quickly spread. On December 17th, Oracle's stock price fell by more than 5%, nearly 50% lower compared to its historical high in September. The debate over the AI bubble has become the focus of the US stock market.
