Africa’s biggest companies are becoming increasingly important to the continent’s investment and business landscape, with firms in technology, banking, mining and telecommunications commanding billions of dollars in market value.
According to the July 2026 edition of the Mansa 100 by Mansa Markets, the combined value of the 100 most valuable publicly listed African companies was approximately $650 billion. The ranking measures companies by US dollar market capitalisation and provides a snapshot of where Africa’s corporate wealth is concentrated.
Naspers emerged as Africa’s most valuable listed company, with a market capitalisation of roughly $40 billion. The South African technology and investment group has significant exposure to global technology businesses, making it one of the continent’s most valuable corporate names.
AngloGold Ashanti ranked second at about $38 billion, followed by South Africa’s FirstRand, Capitec Bank and Standard Bank to complete the top five. The strong presence of banks among the leading companies highlights the importance of financial services to Africa’s corporate economy.
The mining sector is also strongly represented. Gold Fields ranked sixth, while other major gold producers also appeared among the continent’s largest companies. Rising gold prices have helped increase the value of African mining companies and strengthened their position in global financial markets.
Telecommunications is another major force. MTN Group, Vodacom, Airtel Africa, MTN Nigeria, Safaricom and MTN Ghana all featured in the Mansa 100. Their presence reflects the continued expansion of mobile communications, internet services and digital financial products across African markets.
South Africa dominates the ranking, with 54 companies listed on the Johannesburg Stock Exchange appearing among the 100. Nigeria follows with 18 companies, while Egypt contributes 14, Kenya five, Malawi five and Ghana four.
Nigeria’s position is particularly significant because it shows the growing weight of the country’s listed companies within the wider African investment market. Companies such as Airtel Africa, MTN Nigeria and Dangote Cement provide exposure to some of the continent’s largest consumer and industrial markets.
Mansa Markets said its ranking focuses on African companies listed on African exchanges whose businesses are fundamentally African. It excludes secondary listings of global companies whose primary operations and economic base are outside the continent.
The market values are converted into US dollars using official exchange rates, while the live ranking changes with share prices. Mansa Markets also publishes a fixed monthly edition so that journalists, researchers and investors can refer to a specific period without the ranking changing afterwards.
The ranking shows that Africa’s corporate power is spread across several industries rather than being driven by one sector. Banking remains a major source of corporate value, while mining benefits from commodity prices and telecommunications continues to gain from Africa’s digital expansion.
For investors, the list offers a useful picture of the companies attracting the most market value across the continent. However, market capitalisation can change daily as share prices and exchange rates move.
