The stock prices of Nvidia, Google, and Apple, the world's top three listed companies by market capitalization, all hit record closing highs on Wednesday, driven by the worldwide artificial intelligence boom.

Nvidia's stock price closed up 2.29 percent at 225.83 US dollars per share on the day, pushing its market capitalization to 5.488 trillion dollars, thus maintaining its top position in the world.

Alphabet, Google's parent company, saw its stock price surge 3.94 percent to 402.62 dollars per share, bringing its total market capitalization to 4.839 trillion dollars.

Apple's stock price rose 1.38 percent to close at 298.87 dollars per share, pushing its market capitalization to 4.39 trillion dollars.

According to US media reports, the recent strong performance of US tech stocks is mainly due to increased spending on AI infrastructure by many companies, coupled with better-than-expected earnings reports, which have boosted market optimism. Apple, on the other hand, has benefited from strong sales of its main products and continued high growth in its services business.
