When Nigerians make phone calls, buy fuel or use mobile internet, they interact with industries that have helped shape the country’s economy. Behind some of these businesses is Mike Adenuga, the billionaire entrepreneur who built major interests in telecommunications and oil.
Adenuga is the founder of Globacom, one of Nigeria’s major telecommunications operators, and has business interests associated with Conoil. His journey from trading to building businesses in capital-intensive industries offers a look at how he accumulated his wealth over several decades.
But how did he move from selling everyday goods to building companies in telecommunications and oil, and how much is he worth today?
Who Is Mike Adenuga?
Michael Adeniyi Agbolade Ishola Adenuga Jr., popularly known as Mike Adenuga, is a Nigerian businessman whose interests span telecommunications, oil and gas, and other investments.
Born in Ibadan on April 29, 1953, Adenuga studied business administration at Northwestern Oklahoma State University in the United States before earning a master’s degree in business administration from Pace University in New York.
According to Forbes, he supported himself during his studies by working as a taxi driver. He also became involved in business at a young age, selling lace materials and distributing soft drinks.
These early ventures provided his first experience of trading and identifying commercial opportunities. Forbes reports that he made his first million at the age of 26, before moving into larger investments in oil and telecommunications.
How Mike Adenuga Made His First Million
Adenuga’s early business activities centred on trading and distribution. He sold lace materials and distributed soft drinks, building experience in sourcing products and connecting them with customers.
Although these activities were different from the industries he later entered, they provided a starting point for his entrepreneurial journey.
Rather than remaining in trading, Adenuga went on to pursue opportunities in sectors requiring substantially more capital and infrastructure. His later investments in oil exploration and telecommunications would become central to his business empire.

How He Built His Oil Business
Adenuga’s expansion into the energy sector became an important part of his business journey. In 1990, he obtained a drilling licence and began exploring opportunities through Consolidated Oil, later associated with Conoil Producing.
In December 1991, the company became the first indigenous Nigerian company to discover crude oil in commercial quantities, according to accounts of its history. The achievement marked an important milestone in the development of locally owned participation in Nigeria’s oil exploration industry.
Oil exploration requires substantial capital, technical expertise and long-term investment. Success in the sector can also be affected by global oil prices, production costs, regulation and the availability of infrastructure.
Adenuga’s oil interests provided another major business interest alongside his later investments in telecommunications.
Today, his interests include Conoil Producing, which is involved in oil exploration and production, and Conoil Plc, which operates in the petroleum products market.
How Globacom Changed His Business Journey
Adenuga expanded into telecommunications as mobile phone services began opening up in Nigeria. He obtained a conditional GSM licence in 1999, although it was revoked before the business could launch.
He later secured another licence, and Globacom launched in Nigeria in August 2003.
At the time, mobile telecommunications remained expensive for many Nigerians. Globacom entered the market with lower entry costs and introduced per-second billing, challenging the pricing practices of established operators.
Its entry helped intensify competition in the telecommunications market. More affordable access and growing competition contributed to the expansion of mobile services, although the sector’s wider growth also depended on investments by other operators, regulatory changes and rising consumer demand.
Globacom subsequently invested in telecommunications infrastructure, including the Glo-1 submarine fibre-optic cable connecting Nigeria and other West African markets to international networks.
These investments helped establish telecommunications as one of the most visible parts of Adenuga’s business interests.
However, operating a telecommunications company also involves substantial costs, including network maintenance, technology upgrades, spectrum and infrastructure investments. Globacom’s business value and Adenuga’s wealth therefore depend on more than the number of customers using its services.

How Mike Adenuga Makes His Money
Adenuga’s estimated wealth is associated with his holdings across several businesses. His major interests include:
Telecommunications: Globacom is one of the main businesses associated with Adenuga. Its operations span mobile communications and data services, supported by significant telecommunications infrastructure.
Oil and gas: His interests include Conoil Producing, which operates in oil exploration and production, as well as Conoil Plc, a publicly traded petroleum marketing company.
Financial investments: Forbes identifies a minority holding in Sterling Financial Holdings among his publicly reported investments.
These interests are important when examining his wealth because a billionaire’s net worth is not simply the amount of money earned from one company. It is an estimate of the value of assets and business holdings, minus liabilities where these can be accounted for.
The value of private businesses such as Globacom can be particularly difficult to establish because they do not publish the same level of financial information as publicly listed companies.
Mike Adenuga’s Estimated Net Worth in 2026
According to Forbes’ real-time billionaire profile, Mike Adenuga’s estimated net worth was $6.9 billion as of October 27, 2026.
Forbes’ 2026 annual list of Africa’s richest people placed his estimated wealth at $6.5 billion. The annual list and real-time tracker can show different amounts because they use different valuation dates and the real-time estimate changes as market values move.
These figures are estimates rather than a complete public accounting of Adenuga’s personal assets and liabilities. His wealth is associated with businesses operating in industries where valuations can change with market conditions, company performance, currency movements and investor expectations.
It is also important to distinguish his personal net worth from the revenue generated by Globacom or Conoil. Company revenue is the money a business generates from its activities; it is not the same as profit or the value of the owner’s personal holdings.
What His Business Journey Shows
Adenuga’s career demonstrates how an entrepreneur can move from trading into industries that require long-term capital investment. His early commercial activities were followed by investments in oil exploration and telecommunications, two sectors with significant infrastructure and operating requirements.
His story also highlights the importance of timing and competition. Globacom entered Nigeria’s mobile market after other operators had established themselves, but its pricing strategy helped it compete for customers who had previously found mobile services expensive.
At the same time, building a large business does not guarantee that growth will continue without challenges. Telecommunications operators face changing technology, infrastructure costs and intense competition, while oil businesses are exposed to market and production risks.
For aspiring entrepreneurs, Adenuga’s journey offers an example of how business interests can expand over time. It also shows why sustainable growth requires more than a promising idea: it depends on investment, operational execution and the ability to respond to changing market conditions.
The Mike Adenuga We Know Today
Mike Adenuga built a business empire through investments in telecommunications and oil, expanding beyond the trading activities that marked the beginning of his career. Globacom became a major part of his business identity, while his oil interests added another source of exposure to Nigeria’s energy sector.
Forbes estimated his net worth at $6.9 billion on October 27, 2026, although that figure can change as business and market valuations move.
His journey offers an example of how long-term investment and expansion into essential industries can create substantial wealth. It also highlights the importance of distinguishing a company’s performance from the personal wealth attributed to its owner.
