Africa is often discussed through the lens of population, natural resources and economic growth. But another part of the continent's economic story is becoming increasingly difficult to ignore: the growth and concentration of private wealth.

Africa is home to thousands of high-net-worth individuals, including millionaires, centi-millionaires and billionaires who have built fortunes across industries ranging from mining and manufacturing to technology, finance, telecommunications, property and consumer goods.

According to the Africa Wealth Report 2025, Africa had approximately 122,500 millionaires, 348 centi-millionaires and 25 billionaires. The report also highlights how concentrated this wealth is, with five countries — South Africa, Egypt, Morocco, Nigeria and Kenya — accounting for about 63% of the continent's millionaire population and 88% of its billionaires.

So, which African countries have the most millionaires and billionaires?

1. South Africa

South Africa is by far the largest millionaire market in Africa.

The 2025 Africa Wealth Report estimates that the country has 41,100 resident millionaires, meaning roughly one-third of Africa's millionaire population lives in South Africa.

The country's wealth is supported by a relatively sophisticated financial system, established stock markets, mining, manufacturing, property, retail, professional services and a deep corporate sector.

Johannesburg remains the continent's leading wealth center. The report estimates that the city is home to 11,700 resident millionaires, more than any other African city. Cape Town follows with approximately 8,500.

South Africa is also home to several of the continent's billionaires.

However, its wealth story is not entirely positive. The country's millionaire population declined by about 6% over the decade covered by the report, reflecting economic pressures and the movement of wealthy individuals to other countries.

2. Egypt

Egypt ranks second, with approximately 14,800 millionaires.

Its position is hardly surprising given the size and diversity of the Egyptian economy. Cairo is a major commercial center, while sectors such as real estate, construction, telecommunications, tourism, manufacturing and financial services have created substantial private fortunes.

Egypt also has one of Africa's largest billionaire populations. The 2025 wealth data put the country ahead of most African markets in terms of billionaire numbers.

The country's enormous domestic market is another advantage. Businesses serving hundreds of millions of consumers can potentially achieve significant scale, particularly in sectors such as property, retail, infrastructure and consumer goods.

3. Morocco

Morocco has approximately 7,500 millionaires, placing it third among African countries.

What makes Morocco particularly interesting is the direction of its wealth growth.

The country's millionaire population increased by approximately 40% over the decade covered by the 2025 report.

Casablanca is at the center of much of this activity. As Morocco's commercial and financial capital, the city has attracted businesses involved in banking, manufacturing, logistics, telecommunications, property and international trade.

Morocco's geographical position also gives it an unusual advantage. It sits close to Europe while maintaining strong commercial connections with other parts of Africa.

4. Nigeria

Nigeria has approximately 7,200 millionaires.

The country has one of Africa's largest and most entrepreneurial economies, producing major fortunes across energy, telecommunications, manufacturing, financial services, food production and consumer businesses.

Nigeria is also home to some of Africa's best-known billionaires, including entrepreneurs whose companies have become major players in cement, food, telecommunications and other essential industries.

However, Nigeria's wealth numbers also illustrate an important distinction between economic size and wealth growth.

The Africa Wealth Report indicates that Nigeria's millionaire population declined by approximately 47% over the decade covered by the report.

Currency movements, economic conditions and the relocation of wealthy individuals can all influence these figures.

5. Kenya

Kenya rounds out Africa's “Big Five” wealth markets with approximately 6,800 millionaires.

Nairobi is the country's main wealth center and has developed into one of East Africa's most important financial, technology and business hubs.

Kenya's wealth creation story is broader than traditional industries. Banking, telecommunications, technology, real estate, agriculture, manufacturing and professional services have all contributed to the country's expanding private sector.

The country's digital economy has also created opportunities that did not exist at the same scale a generation ago.

6. Mauritius

Mauritius is one of the most interesting countries in Africa's wealth rankings because of its size.

Despite being a relatively small island nation, Mauritius has approximately 4,800 millionaires according to the 2025 figures reported by Henley & Partners.

More importantly, it has recorded the continent's strongest millionaire growth over the past decade.

Henley & Partners reports that Mauritius experienced approximately 63% growth in its millionaire population over that period.

Financial services, investment, tourism, property and its international business environment have helped make Mauritius an important wealth hub.

7. Algeria

Algeria also has a substantial millionaire population, although its wealth market has faced challenges.

The country benefits from significant natural-resource wealth, particularly its energy sector, while major cities such as Algiers provide centers for commerce and professional services.

The 2025 wealth data indicate that Algeria's millionaire population declined over the preceding decade.

That illustrates an important point about wealth rankings: a country can have enormous natural resources without automatically producing rapid growth in the number of wealthy residents.

8. Ghana

Ghana has developed a growing private wealth market supported by finance, property, mining, entrepreneurship, telecommunications and consumer businesses.

Accra is particularly important. The capital has become an increasingly prominent West African destination for entrepreneurs, investors and international businesses.

Ghana's wealth market is smaller than those of South Africa, Egypt or Nigeria, but its entrepreneurial ecosystem gives it an important position in the wider African economy.

9. Namibia

Namibia has a relatively small population but a notable concentration of private wealth.

Mining, financial services, tourism, property and related industries have helped create affluent business communities.

The country also stands out because its millionaire population has shown strong growth over the longer term. The 2024 Africa Wealth Report projected more than 85% millionaire growth in Namibia over the following decade.

10. Ethiopia

Ethiopia has a very different wealth story from Mauritius or Namibia.

Its enormous population and expanding urban economy create a large potential market for entrepreneurs and businesses.

Addis Ababa is the country's commercial and diplomatic center, with growing activity in construction, manufacturing, services, transportation and technology.

Although Ethiopia's millionaire population remains much smaller than South Africa's or Egypt's, its economic scale gives the country significant long-term potential.

Where Are Africa's Billionaires Concentrated?

Millionaires and billionaires are not distributed evenly across the continent.

The 2025 Africa Wealth Report estimates that Africa has 25 billionaires, with the majority concentrated in a small number of countries. South Africa, Egypt, Nigeria and Morocco are particularly important billionaire markets.

This concentration makes sense when the structure of Africa's largest economies is considered.

Large fortunes generally emerge where entrepreneurs and investors have access to sizeable markets, capital, established companies, natural resources or industries capable of operating at enormous scale.

South Africa's mining, financial and consumer sectors have produced substantial wealth. Egypt has major fortunes connected to construction, telecommunications and other industries. Nigeria has created billionaires through manufacturing, telecommunications, food and energy-related businesses.

What Is Creating New Wealth in Africa?

The traditional sources of African wealth are changing.

Mining and natural resources remain important, but they are no longer the only routes to substantial private fortunes.

Technology is opening new opportunities. Fintech companies, digital marketplaces and software businesses can potentially reach millions of customers without requiring the physical infrastructure associated with older industries.

Real estate remains another major source of wealth, particularly in rapidly expanding cities.

Financial services, manufacturing, logistics, telecommunications and consumer businesses are also important because Africa's growing urban population is creating demand for products and services.

The most interesting development may therefore be the emergence of new types of African wealth.

The continent's future millionaires will not necessarily come from the same industries as previous generations.

Africa's Wealth Story Is Bigger Than a Ranking

A list of countries with the most millionaires and billionaires tells only part of the story.

The number of wealthy individuals can rise or fall because of exchange rates, asset prices, migration, business conditions and changes in how wealth is measured.

It also should not be confused with the financial wellbeing of the average citizen.

A country can have thousands of millionaires while millions of people continue to face significant economic challenges.

What the numbers do show is where Africa's strongest concentrations of private capital currently exist.

South Africa remains the continent's dominant wealth market, while Egypt, Morocco, Nigeria and Kenya form the next major group. Mauritius is particularly notable for its rapid growth, while countries such as Rwanda, Namibia and Morocco demonstrate that smaller or emerging markets can also build wealth at impressive rates.

For investors, entrepreneurs and businesses watching Africa, that geographic distribution is worth paying attention to.

The continent's wealth map is not fixed. As technology develops, cities expand and new industries emerge, the countries producing Africa's next generation of millionaires and billionaires could look very different from today's rankings.
