Nvidia: AI Investment Bubble Concerns Rise Among Investors

Investors are expressing concerns about a potential bubble in artificial intelligence investments, despite Nvidia's impressive financial results. Nvidia's market capitalization is approaching $4 trillion, surpassing all previous records.
Nvidia accounts for 8% of the S&P 500, and its capitalization is approximately 3.6% of global GDP. Half of its revenue comes from just three customers. Sam Altman of OpenAI has mentioned the possibility of an AI bubble.
Economists note that capital expenditures by American technology giants have contributed more to GDP growth this year than private consumption; however, a corresponding increase in productivity and wages has not been observed.
