Who are the Big Five Tech

You have probably met the term Big Four Tech or Big Five Tech somewhere on the Internet. It was created by the journalists to bring together the best and highly valued players of the digital world.

The unofficial term first appeared in 2013, when the investment expert Jim Cramer was speaking about the noteworthy technology stocks. He included Facebook, Amazon, Netflix, and Google to the FANG (the companies names abbreviation) group. Microsoft was not on the list because of the boring stock price at that time.

Since then, different sources include different companies in the Big Tech group depending on the indicator they are interested in.

For example, Goldman Sachs and JP Morgan came up with the version of Big Five Tech, based on market capitalization, the number of acquisitions, and the influence on sociocultural evolution. These companies are:

  • Facebook,
  • Amazon,
  • Apple,
  • Microsoft,
  • Alphabet (Google).

Today, these tech giants have a combined market value of more than $5 trillion. Each of them had numerous large acquisitions and mergers, and their influence on almost all tech fields is significant.

For example, Amazon is one of the leading cloud service providers with a market share of almost 50%. It has also gained 69% of the market of AI-based personal assistants (Google has only 25% of the market).

Alphabet has basically monopolized the popular web-based services, like online search, video sharing, and online mapping and navigation.

Facebook dominates social networking, image sharing, and online messaging. It also shares the leadership with Google on the digital advertising market.

Apple tops the smartphones and computing device sector.

Microsoft remains a leader in the operating systems, as well as productivity software markets. But it is also one of the largest cloud computing companies and one of the biggest in the game industry.

In 2014 the Microsoft bought Nokia company, but the partnership was not successful and ended two years later.


You have probably noticed that all of the world's most powerful tech companies are US-based. But China has its own analogs to Big Tech Five called BATX (Baidu, Alibaba, Tencent, Xiaomi). And some of these promising companies have already reached the top ten.

Besides, there are tons of companies coming and emerging start-ups that strive to the top. So, there's a great possibility that in a few years the Big Tech will look completely different.
