Top 5 Biggest Tech Brands in the World

The tech industry is one of the world’s most competitive and rapidly changing industries. Companies must constantly innovate and adapt to the latest trends to stay ahead of the curve.

These large IT firms have dominated the market in recent decades. Technology has been more pervasive across the economy during the last few decades. The S&P 500 index now has a total weighting of 29.1% for the technology sector, up from 20.7% at the end of 2016 and among the greatest long-term performers on the market.

Even large-cap firms that aren’t strictly categorised as tech firms by the Global Industry Classification Standard, or GICS, including Alphabet Inc. (GOOG, GOOGL), Amazon.com Inc. (AMZN), and Tesla Inc. (TSLA), have operations that are centred upon disruptive technologies.

IT businesses have handled the negative effects of the COVID-19 epidemic despite it. The combined market capitalization of the top five tech companies exceeds $7 trillion.

As a result, a handful of tech brands have become household names.
