Apple Is Now a $4 Trillion Company

Apple Inc.’s share price climbed above US $269 on Tuesday, pushing its market capitalization beyond US $4 trillion. It emerged as only the third public company in history, after Nvidia Corporation and Microsoft Corporation, to achieve this benchmark. 

The surge followed stronger-than-expected demand for Apple’s latest iPhone 17, which, according to industry data, outperformed the previous iPhone 16 series by 14 % in its first ten days in China and the US. 

Since January, Apple shares have gained more than 18%. Nvidia is up nearly 40%, while Microsoft has climbed close to 30%. Nvidia, in particular, hit the US $4 trillion threshold in July 2025 and is now nearing US $4.7 trillion amid high investor conviction in its AI-driven earnings growth. 

Although Apple has modest exposure to AI infrastructure compared with its peers, the market’s enthusiasm reflects its proven launch execution and easing of trade-tariff headwinds. With five members of the “Magnificent Seven” reporting this week, the onus is now on them to convert elevated valuations into sustained earnings momentum. 

What Does This Mean for Me?

Analysts point out that more than 40% of the gains in the S&P 500 this year stemmed from these tech giants. As one market strategist warned, concentrated leadership in a handful of mega-caps increases fragility even as revenues expand. The commentary from corporate executives will be critical in shaping how far and how confidently the market pursues the AI narrative into 2026.
