On July 25, Bloomberg reported that the current fervor surrounding artificial intelligence (AI) is giving rise to a new phenomenon in the stock market: the surge in a company's market capitalization following the announcement of substantial AI investment plans often outstrips the actual amount invested. Take NVIDIA as a case in point. Last week, the company declared a $5 billion equity investment in Intel. Then, on Monday of this week, it unveiled plans to invest up to $100 billion in OpenAI. Remarkably, within just three trading days after these investment plans were made public, NVIDIA's market cap soared by over $320 billion—triple the anticipated investment sum.
