The article discusses the potential impact of artificial intelligence (AI) on the stock market, particularly the S&P 500 index. According to Goldman Sachs, the AI boom could drive a 15% upside for the S&P 500 over the next two years. The bank’s analysts believe that AI will be a key driver of productivity growth and corporate earnings, leading to a significant boost in stock prices. However, they also caution that the AI-driven rally may not be sustainable beyond 2024, as the market could become overheated and signal a potential bubble. The article highlights that while AI is expected to be a game-changer for various industries, investors should remain cautious and monitor market conditions closely to avoid potential risks associated with overvaluation.
