Who Is Mike Adenuga? Early Life and Education
Michael Adeniyi Agbolade Ishola Adenuga Jr. was born on 29 April 1953 in Ibadan, in south-west Nigeria. He attended Ibadan Grammar School before continuing his studies abroad.
In the United States he studied business administration at Northwestern Oklahoma State University and Pace University in New York. By his own account, he drove a taxi to help fund his education.
That early hustle became part of his legend — a billionaire who started with very little and built everything himself.
Building a Business Empire
Back in Nigeria, Mike Adenuga made his first fortune as a young man, trading goods such as lace and distributing soft drinks before moving into bigger ventures.
He reportedly made his first million in 1979. From there he diversified aggressively, eventually founding Equitorial Trust Bank and pushing into the capital-intensive worlds of oil and telecoms.
His appetite for big, risky bets in industries dominated by foreign players earned him his nickname, “The Bull.”
Mike Adenuga and Indigenous Oil Exploration
Adenuga’s company, Consolidated Oil — later Conoil Producing — made history in 1991 when it struck oil in commercial quantities in shallow waters off the Nigerian coast.
It was the first indigenous Nigerian company to achieve the feat, in an industry long controlled by international oil majors. The success cemented his reputation as a pioneer of local ownership in Nigeria’s most strategic sector.
Globacom: The Glo Story
Mike Adenuga’s most visible business is Globacom. After winning a GSM licence in 2003, Glo launched commercial mobile service later that year as a wholly Nigerian-owned operator challenging bigger international rivals.
Glo built a reputation for aggressive pricing and bold marketing, helping to drive down the cost of calls and data for ordinary Nigerians. It grew into one of the country’s largest networks and expanded into Ghana and Benin.
For many Nigerians, Glo is the face of Adenuga’s empire — proof that a home-grown company could take on the giants of global telecoms.
The company is also remembered for its bold marketing, signing major football stars and entertainers as ambassadors and laying its own submarine internet cable to boost connectivity in the region.
Honours and Recognition
Adenuga has been recognised at the highest levels. He was made a Grand Commander of the Order of the Niger (GCON), one of Nigeria’s top honours.
France elevated him to Commander of its Legion of Honour in 2018 — its highest distinction — and Ghana named him a Companion of the Star of Ghana, reflecting the reach of his businesses across West Africa.
Personal Life and Private Nature
Mike Adenuga is famously reclusive. He rarely grants interviews, seldom appears in public and keeps no personal social media accounts, preferring to let his businesses speak for him.
He has a large family, and his daughter Bella Disu is an executive at Globacom. Through the Mike Adenuga Foundation he supports causes in health, education and youth empowerment.
Mike Adenuga’s Net Worth
As of 2026, Mike Adenuga’s net worth is reportedly estimated by Forbes at around $6.5 billion, placing him among the three richest people in Nigeria and the wealthiest in Africa.
His fortune is built mainly on his ownership of Globacom and his oil interests through Conoil Producing. Because these businesses are privately held, the figure is an estimate and is not officially confirmed.
From driving a taxi to funding his studies to building Glo and Conoil, Mike Adenuga proved a Nigerian could take on the world’s biggest industries — and win.

Controversies
In 2006, Adenuga was briefly questioned by Nigeria’s anti-graft agency, the EFCC, amid a politically charged investigation linked to funding allegations. No conviction followed, and he spent a period abroad before returning to Nigeria in 2007.
Years later, a traditional ruler publicly alleged the probe had been politically motivated — a claim former president Olusegun Obasanjo denied. The episode remains contested, and Viorah TV reports it only as a matter of public record, taking no position.
