Top 30 largest US tech companies 2020

Top US tech companies

The technology sector is the economic star of the United States, leading the country’s growth as well as its financial markets. IT and communications companies are at the heart of innovation, rapidly changing people’s lives and transforming business, finance, and the broader economy.

The largest American technology companies operate in a wide array of industries with products and services that disrupt traditional methods of doing business or create new models that revolutionize entire sectors. With high tech products and high-value-added services, actors of the tech industry are engaged in stiff competition to acquire and keep their share in a number of highly lucrative markets.

This fight for market share is even more fierce as in many tech businesses, the “winner takes all” law proves that the dominant player gets the lion’s share of profits. And the notorious big five American tech companies, Microsoft, Apple, Amazon, Google, and Facebook, are proof of this phenomenon with their unrivaled supremacy over their own respective principal businesses: office software, smartphones, e-commerce, search engines, and social media.

Spearheaded by the big five in this exacerbated rivalry, the large tech companies have no second-thought in developing products to compete against each other or new rising startups. They rely upon their existing customer base or distribution networks to gain market share if they cannot disrupt the market or its business practices.

Even though new actors periodically come to challenge the tech companies in some of their businesses, rare are the companies that grow beyond a few billion in valuation in a domain where large companies are already operating, as they often get acquired before reaching this size. The largest US startups could pose some threats with future diversification, but they often only can reach a large size because they challenge an industry where the existing big tech companies are not yet actively operating.

For now, the most prominent American tech companies are the backbone of the country’s economic growth and a key aspect of its global power. They are also one of the main levers for future high-paying jobs in the US and even though they threaten a number of traditional industries, they also bring hope in the US and around the world that their innovative and disruptive approach to business will bring new useful exciting applications in people’s lives.

List of the top 30 largest American tech companies by market capitalization

To give you more perspective on the actors of the technological sector in the US, details about the thirty largest public companies that make the American tech have been listed hereafter. Each company is detailed with presentations of its sector, sub-industry, activities, market capitalization, a direct link to its website, logo, and stock symbol.

The technology companies listed hereafter are ranked by market capitalization in United States Dollars, as of effective close on Friday, February 7, 2020. They are defined in accordance with the Global Industry Classification Standard (GICS) as belonging to the specific sectors of Information Technology or Communication Services, or Consumer Discretionary, for Amazon since it is primarily involved in the sub-industry of Internet & Direct Marketing Retail.

The other companies are engaged in a variety of technology sub-industries, including Systems Software, Wireless Telecommunication Services, Internet Services & Infrastructure, Application Software, Data Processing & Outsourced Services, Semiconductors, Cable & Satellite, IT Consulting & Other Services, Movies & Entertainment (for Netflix), Communications Equipment, Integrated Telecommunication Services, Interactive Media & Services, and Technology Hardware, Storage & Peripherals.

Remark that other important actors were not included in this list as their core business is not part of the technology sector. Even though Walmart is a key player in e-commerce, its core business is in retail; the same goes for Disney which has recently launched Disney+ to offer its content catalog through video-on-demand and notably competes against Netflix, as Disney’s core business is in movies and amusement parks.
