Nvidia shares rose as much as 27% in June, boosting its market capitalisation to $3.34 trillion, before giving up some of their gains later in the month due to profit booking and concerns over its high valuations.

Microsoft's market capitalisation increased by 7.6%, while that of Apple Inc. surged 9.6% over the past month.

Meanwhile, Amazon.com Inc, hit $2 trillion in market value last month, becoming the fifth United States company to achieve the milestone, riding on AI-influenced enthusiasm.

Broadcom Inc.'s market capitalisation jumped about 20% last month after it increased its annual revenue forecast for AI-related chips by 10% and announced a stock split to capitalise on this year's rally in its shares.
