In 2015, no one could have truly imagined the immense growth that would unfold in the American technology sector over the subsequent decade. The companies now known as the “Magnificent Seven” – Apple, Microsoft, Alphabet (Google), Amazon, Meta (Facebook), Tesla, and NVIDIA – then boasted relatively “modest” market capitalizations in the hundreds of billions. However, by 2025, each of them had surpassed the trillion-dollar mark, with some even tripling that valuation, fundamentally reshaping the global investment map.

Less Than a Decade: From Billions to Trillions – A Tech Success Story

By 2018, none of these companies had crossed the trillion-dollar threshold. Apple was the first to break this historic barrier in August 2018, during a two-year period where the capital market enthusiastically responded to iPhone developments, the shift to digital services, and exceptional profit volumes. In the same year, Microsoft and Amazon were hot on its heels, though all were still in the hundreds of billions range.

Just three years later, in 2021, the American capital market witnessed a true revolution: six of the seven companies had already surpassed the trillion-dollar mark. Apple exceeded $2.9 trillion, Microsoft crossed $2.5 trillion, and Amazon reached $1.6 trillion. This rapid growth occurred against the backdrop of the COVID-19 pandemic, which accelerated global digital transformation processes and propelled the technology sector to unprecedented heights. Investors who identified this trend early reaped substantial returns.

The Meteoric Ascent of NVIDIA: Leading the AI Revolution

One of the most prominent and fascinating trends in recent years has been the dramatic rise of NVIDIA. In 2015, its market capitalization was negligible – less than $20 billion. By 2021, it was still “behind” with about $736 billion. However, the growth recorded between 2022 and 2025 was unprecedented: the company crossed the $3.85 trillion mark in July 2025 and became the largest company in the U.S. by market capitalization. The primary explanation lies in the surge of Artificial Intelligence (AI), where NVIDIA has become a dominant player in the chip market, particularly in AI chips. This is a prime example of smart investment in breakthrough technologies.
