9 Best Examples of Monopoly In Different Industries

The term monopoly comes from two Ancient Greek words Monos, which means “single,” and Poleo, which means “sell.” Roughly translated, this means “single seller.”

A monopoly can be defined as a market structure in which there is one seller and many buyers. The seller has a unique product with no substitutes and no competitors.

The verb monopolize refers to a process by which an organization gains the ability to exclude competitors and increase prices. In law, a monopoly is a single business entity with substantial market power. In economics, a monopoly is a single seller.

Although monopolies differ from industry to industry, they tend to have similar characteristics, such as:

  • Sole seller: The whole market is served by one company, and the company becomes the same as the industry it serves.
  • High barrier to entry: Competitors cannot easily enter the market due to several reasons, such as high startup costs, patents, and government regulations.
  • Price maker: Monopolies can set and raise the price of their products at will.
  • Economies of scale: Due to the large scale of manufacturing and distribution networks, monopolies can offer products and services at lower costs than any of the competitors in the industry.

Monopolies often help a region or country develop its infrastructure rapidly, effectively, and efficiently. However, when an organization becomes too dominant (leaving almost no room for competition), its quality and services can suffer. Sometimes, this leads to higher consumer costs and corrupt behavior.

Generally, United States law doesn’t stop/punish an organization for being the sole provider of products and services, but it can punish any company for using biased or unfair practices to maintain its position.

Such market structures can better be explained using examples. Below, you will find some of the most common examples of monopoly in various industries.

9. Standard Oil

Gained almost 90% of the oil refining market in the US 

Established in 1870 by American industrialists John Davison Rockefeller and Henry Flagler, Standard Oil was an oil-refining, transporting, and marketing company. Although the company had tons of competitors, it managed to gain nearly 90% of the US market.

By 1910, it had become the world’s largest oil refiner. The company streamlined production and logistics and reduced prices, undercutting competitors. Standard Oil was accused of using aggressive pricing to threaten other businesses and form a monopoly.

In 1911, the US Supreme Court found Standard Oil guilty of monopolizing the petroleum industry through multiple anti-competitive and abusive actions. The court ruled that the company must be dissolved under the Sherman Antitrust Act (of 1890).

As a result, Standard Oil was split into 34 separate entities, which included companies that became Chevron Corporation, ExxonMobil, and others — some of which still generate hundreds of billions in annual revenue.

Rockefeller owned a 25% share in each of the new companies. And due to the arrival of the gasoline-driven automobile, his personal wealth skyrocketed. He was worth $900 million in 1913, more than 2% of that year’s US GDP. 

8. Carnegie Steel Company

Carnegie Steel Corporation mill

Dominated steel industry for years in the US 

Established by Andrew Carnegie, Carnegie Steel Company became the dominant steel supplier in the United States in the late 19th century. It utilized a vertically integrated manufacturing process that consistently incorporated the latest technical methods.

Since steel is a commodity product, low-cost production is the key to a successful business. Carnegie implemented its business model in two ways. The first was owning raw material supplies such as coal, lime, and iron ore. The second was producing unparalleled scale through productivity gains and capacity expansion.

Carnegie successfully ran a monopoly for years in the steel industry. In 1901, JP Morgan bought the Carnegie Steel Company and melded it into the United States Steel Corporation.

The company was sold at nearly $492 million, of which $226 million went to Andrew Carnegie. This deal made him one of the richest men in history.

After the acquisition, the United States Steel Corporation got 60% of the steel production market, which reduced over time as smaller companies became more innovative and efficient. Despite this, US Steel still generates annual revenue of more than $12 billion and employs over 29,000 people.

7. Luxottica

Ray-Ban Clubmaster sunglass

Accused of functioning as a complete monopoly in the eyewear industry

Luxottica is an Italian eyewear company that designs, manufactures, and distributes glasses. Its two main products are prescription frames and sunglasses.

Ray-Ban, Prada, Ralph Lauren, Versace, Armani Exchange, Chanel, Oliver Peoples, Bulgari, and Burberry are some of its popular brands. In fact, the company controls nearly 80% of the major brands in the multi-billion dollar global eyeglasses industry, generating $18 billion in annual revenue.

Luxottica owns not only a large portfolio of brands but also several eye insurance groups and optical departments at Sears and Target. It has been criticized for overcharging for its products and accused of operating a monopoly.

In 2018, Luxottica merged with Essilor, a French-based international ophthalmic optics company, forming a single entity, EssilorLuxottica, which has a combined market cap of over $80 billion. Furthermore, EssilorLuxottica holds 30% of the global market share and accounts for nearly one billion pairs of frames and lenses sold annually.

6. Google Search Engine

Google dominates the internet search engine with over 88% of the market share

More than two decades ago, Google emerged as an innovative way to search the emerging internet. That Google is long gone. Today’s Google is a monopoly gatekeeper for the internet, which generates hundreds of billions of dollars in revenue every year.

Google has been accused (several times) of unethically protecting its monopoly over search and search advertising. The United States Department of Justice, for instance, has accused Google of making deals with other tech giants like Apple and suppressing competition through exclusive business agreements and contracts.

The company deals with several mobile carriers and handset manufacturers to make Google the default search engine. It has also acquired hundreds of smaller companies since its inception, many of which have helped Google grab over 88% of the US search market.

However, Google has always defended itself by saying that ‘competition is only a click away, and its services have helped thousands of small firms.’

“People use Google because they choose to, not because they are forced to, or because they cannot find alternatives.” — Kent Walker, Google’s chief legal officer

5. YKK

Manufactures 90% of all zippers and fastener products

YKK (stands for Yoshida Kogyo Kabushikikaisha) is the world’s largest zipper manufacturer. It also makes architectural products, plastic hardware, fastening items, and industrial machinery from over 100 facilities in 71 countries.

The company produces almost 90% of all zippers and fastener products around the world. Its products can be found in various things, ranging from laptop cases to jeans.

YKK’s success is certainly not unwarranted. It has been able to deliver high-quality products for decades while maintaining an acceptable price.

Its pricing makes it difficult for competitors to enter the market. The Chinese, despite plenty of cheap labor and costless capital, haven’t found a way to make their way into this industry.

It’s quite hard to believe that most Chinese garment markers import Japanese zips. Whatever the reason behind this strange fact, YKK has managed to monopolize a highly competitive, commoditized industry.

4. Saudi Aramco

Headquarters of Saudi Aramco in Dhahran

Saudi Arabia’s giant state oil monopoly is worth over $2 trillion 

Most existing monopolies do not entirely dominate the global industry. Instead, they control large assets in one region or country. This kind of phenomenon, known as nationalization, often occurs in the banking, transportation, and energy sectors.

One such example of a nationalized major asset is Saudi Aramco, a Saudi Arabian multinational petroleum and natural gas company based in Dhahran. With an annual profit of over $88 billion, it is the largest profit-making company in the world.

The company has the largest daily oil production capacity and the second-largest crude oil reserves. It manages the Master Gas System, the world’s biggest hydrocarbon network, and controls more than 100 oil and gas fields in Saudi Arabia. It also operates the world’s largest onshore and offshore oil fields (Ghawar Field and Safaniya Field, respectively).

Between 1988 and 2015, Saudi Aramco alone accounted for nearly 4.5% of the global industrial greenhouse gas emissions.

3. De Beers Group

De Beers store in Paris

Controlled 80% of the rough diamond distribution for over a century 

Established in 1888, De Beers has a long history of monopolistic practices. It specializes in diamond mining, diamond trading, and industrial diamond manufacturing.

Cecil Rhodes, the founder of De Beers, bought dozens of diamond mines in the late 19th century, building the company’s first monopoly over the South African mines. This was the beginning of De Beers’s major monopoly over the global diamond market.

Rhodes continued purchasing both mines and diamonds from other companies. He made agreements with various suppliers, which allowed his company to dominate as much as 85% of the global diamond market.

However, by the end of the 1950s, several new mines were discovered in Canada, Australia, and Russia. The Argyle Diamond mine in Australia and the Alrosa state-owned mine in Russia, for example, gradually started bypassing the De Beers distribution channel.

This made it very difficult for De Beers to maintain its control over global supply. As a result, it started losing market share and eventually lost monopoly status in the diamond market, though it still sells nearly 30% of the global diamond production.

In terms of volume, De Beers Group is currently the second-largest producer, holding a market share of approximately 22%. In contrast, Alrosa accounts for 27% of global diamond extraction.

2. Microsoft

Internet Explorer 4.0 released in 1997 

Accused of creating a monopoly by giving its browser for free 

One of the world’s most successful software companies, Microsoft, has been accused of anti-competitive and monopolistic practices by virtually every modern nation.

The company was accused of building a monopoly by giving its browser (Internet Explorer) software for free, which led to the collapse of rival Netscape. In 1998, the Department of Justice filed antitrust charges against Microsoft for such monopolistic actions.

It was further alleged that the free software programs that come with Microsoft Windows restrict the market for competing web browsers. The company was also questioned whether it had manipulated its application programming interfaces to favor Internet Explorer over other web browsers.

The case focused less on interoperability and more on predatory techniques and market barriers to entry. In the settlement, Microsoft agreed to share computing interfaces with other tech companies.

In 2004, Microsoft was fined €497 million by the European Union for abusing its dominance with the Windows operating system. The company paid the fine in full and released new versions of Windows XP without Windows Media Player.

1. AT&T

Standard Western Electric telephone set, rented to subscribers in the US

Held monopoly on phone service in the US and Canada for over 7 decades 

AT&T is currently the world’s largest telecommunication company and the largest provider of mobile and fixed telephone services in the US. After the acquisition of WarnerMedia, AT&T also became the largest media company in the world (in terms of revenue).

Its history began as a part of the Bell Telephone Company established by Alexander Graham Bell in 1877, which later became AT&T Corporation.

AT&T dominated the telephone service in both the US and Canada throughout most of the 20th century. In the 1910s, the company had a slogan:

One policy, One system, Universe service

And this remained AT&T’s philosophy for the next seven decades. It bought several smaller phone companies during the early 20th century. In order to avoid any actions from antitrust regulators, the company made an agreement called the Kingsbury Commitment with the federal government. This agreement enabled the company to operate as a monopoly until 1984.

The United States v. AT&T antitrust case (opened in 1974 and finalized in 1982) led to the breakup of AT&T into seven regional Bell operating companies and a smaller new AT&T, which emphasized long-distance services.

Companies Having Significant Shares in an Industry 

Many companies dominate their sectors, but they aren’t strictly considered monopolies in a legal sense. They face competition in different aspects of their businesses. Some popular examples include:

Amazon in the e-commerce market

Amazon is the largest online retailer globally, holding over 37% of the US e-commerce market. Its dominance is evident in a broad range of produce categories, from books and electronics, and it has become a go-to platform for online shopping for millions of customers. 

The company also holds over 31% of the global cloud infrastructure. Amazon Web Services is a leading player in the cloud services industry, offering storage, computing power, and infrastructure to businesses of all sizes. This diversification has significantly added to Amazon’s overall market value.


Pfizer holds approximately 9% of the world’s pharmaceutical drug market. It has had a substantial impact on the market, both in terms of drug prices and its overall role within the sector. 

As a leading pharmaceutical company, Pfizer wields significant pricing power for its patented drugs. It focuses on developing high-cost specialty drugs, especially in fields like oncology and rare diseases. Additionally, the company invests heavily in R&D to innovate and address unmet medical needs.

JP Morgan Chase

With over $3.9 trillion in total assets, JP Morgan Chase is one of the largest and most influential banks globally. Its consistent ranking among the largest banks by market capitalization reflects its substantial value in the financial markets.

Due to its size and involvement in various financial activities, the bank is often viewed as an economic indicator. Its performance and financial health can reflect broader economic trends and conditions.

More to Know

What is the difference between a monopoly and a competitive market?
Monopoly Competitive Market
There is one major seller  There are multiple sellers 
Products are unique, and limited alternatives are available  Diverse range of products and brands
High barriers; difficult for new firms to enter Low barriers; new firms can easily enter the market
Can influence and manipulate prices Prices are determined by supply and demand forces
Limited choices, consumers may lack options Wide range of choices, consumers have more options
Higher profit margins to pricing power Lower profit margins due to competitive pressures
May lack incentives for innovation Incentives for innovation to stay competitive
How do monopolies form?

Monopolies are usually formed in industries where high fixed costs are required to acquire customers and have a meaningful return on investment. Buying up the competition, buying exclusive rights (from the government) to provide goods and services, hoarding a scarce resource, or using intellectual property rights are some of the common ways to monopolize the market.

What are the main characteristics of a monopoly?

A monopoly can have one or more of these characteristics:

  • Higher barriers to entry in the sector
  • Price maker
  • price maximizer
  • Ability to change the quantity or price of the product without affecting the business
  • The whole market is served by a single seller, or the firm is the same as the industry


What are the disadvantages of a monopoly market?

While monopolies can benefit from economies of scale (lower average costs) and have deep pockets to fund research and development, they have several disadvantages —

  • Higher prices: Since monopolies face inconsistent demand, they can increase prices at any time. For example, when Microsoft had a monopoly on Desktop software in the 1980s, they charged higher prices for MS Office.
  • Price discrimination: Monopoly companies sometimes practice price discrimination, where they charge different prices for different consumers for the same product.
  • Inferior products and services: A monopoly firm may willingly offer inferior goods and services because they know that consumers have no other choice.
Are there global initiatives addressing international monopolies?

While there is no single global initiative specifically created to address international monopolies, various international organizations and agreements aim to promote fair competition and prevent anticompetitive practices on a global scale. Popular organizations or initiatives include: 

  • Organization for Economic Co-operation and Development (OECD) promotes policies that improve economic and social well-being globally.
  • United Nations Conference on Trade and Development (UNCTAD) provides guidance on competition law and policy. 
  • International Competition Network (ICN) facilitates cooperation and communication among antitrust agencies. 
  • World Trade Organization (WTO) recognizes the importance of competition policy in the context of international trade. 
  • Bilateral and Regional Agreements often have provisions about antitrust measures and addressing anticompetitive practices that might have cross-border effects.

    I liked your content on Best Examples of Monopoly In Different Industries. You have very well explained this.

  • The most harmful oligopoly to the average American is the Big 4 meatpacker stranglehold on the price of meat. The meatpackers absolutely OWN the House and Senate Ag Subcommittees, and prevent any anti-trust action against them.
