Dr. Mike Adenuga Jr., GCON, belongs firmly in the latter group. As he turns 72, his story stands as a powerful reminder of what vision, grit, and quiet determination can build. From driving taxis in New York as a student to becoming a telecom and oil magnate in Africa, Adenuga’s life is both inspiring and deeply human—a story of ambition, setbacks, and bold decisions that paid off.
Mike Adenuga’s path to oil and telecom wealth
To understand how far he’s come, you have to look back at where it all started. Born to modest beginnings in Ibadan, Adenuga’s early years were shaped by a strong work ethic and a desire to do more. He attended Ibadan Grammar School and later Comprehensive High School in Aiyetoro, where he earned his Higher School Certificate. Driven by the dream of a better future, he left for the United States to study business administration, first at Northwestern Oklahoma State University and then at Pace University in New York. To make ends meet, he drove taxis—an experience that not only helped pay tuition but taught him valuable lessons about sacrifice and resilience.
By the time he returned to Nigeria in 1974, the country was riding high on an oil boom. While others focused on consumption, buying flashy imported cars, Adenuga noticed something different: many of those cars lacked basic features like air conditioning and quality sound systems. What looked like a small inconvenience to others looked like a business opportunity to him. That early instinct to spot gaps and fill them would become the hallmark of his career. Over the years, Adenuga built an empire—founding Globacom, Nigeria’s leading indigenous telecom company, and leading Conoil Plc and Conoil Producing to become major players in petroleum marketing and oil exploration. His companies have created thousands of jobs and brought services to millions across the continent. But none of it came easy. Behind the success are years of calculated risks, long nights, and a deep commitment to building something that would last.
From stereos to shallow-water strikes
Adenuga began importing car stereos and air-conditioning units, quickly rising to become Africa’s leading importer in the segment. His entrepreneurial instincts were sharp; he not only identified what people needed, but anticipated what they would want next. It was this foresight that led him to introduce Nigeria to removable car stereos—an innovation that addressed rampant car theft and cemented his status as a market leader. He often recalled, in one of his rare interviews, “We were able to bring it ahead of competition and that really gave us a strong head start.” By the age of 26, he had made his first million through this venture and by trading in lace fabrics and soft drinks.
But that was merely the beginning. Instead of resting on early success, Adenuga plowed his wealth into new ventures—diversifying into banking, real estate, and eventually the oil sector, where his audacity would alter Nigeria’s energy narrative. In the early 1990s, when oil exploration was largely the domain of multinational giants, Adenuga staked $100 million of his fortune into oil block development through his company, Consolidated Oil. It was a gamble that paid off. In 1991, he made history by becoming the first Nigerian to discover oil in commercial quantities in the country’s shallow waters. This milestone birthed Conoil Producing Limited, now one of Nigeria’s largest indigenous exploration companies, operating six prolific blocks in the Niger Delta with estimated reserves exceeding 400 million barrels of oil and 1.8 trillion cubic feet of gas.
Globacom drives West Africa connectivity
Yet even as Conoil thrived, Adenuga had his eyes on another revolution—telecommunications. In the early 2000s, mobile phones were still the preserve of Nigeria’s elite, with SIM cards priced as high as $250. Adenuga envisioned a different future—one where every Nigerian, from the cities to the villages, could connect seamlessly. After a brief regulatory setback that saw his telecom license revoked and later reinstated, he launched Globacom in 2003. His bold strategy of slashing SIM card prices and offering competitive tariffs rapidly democratized access. Globacom wasn’t just a telecom company; it was a movement. He didn’t stop there. With a $1.5 billion investment, Adenuga spearheaded the construction of Glo-1, a 6,100-mile submarine cable linking Nigeria to Europe. It was a bold infrastructure play that significantly boosted broadband connectivity across West Africa.
Today, Globacom is Nigeria’s second-largest mobile operator with over 60 million subscribers, and it continues to expand into underserved regions. His MoneyMaster Payment Service Bank initiative is also setting a new standard for financial inclusion, deploying over 100,000 agents to deliver banking services to Nigeria’s unbanked population. Through Bella Disu, his enterprising daughter and executive vice-chair of Globacom, the Adenuga family’s real estate footprint has grown via Cobblestone Properties. Projects such as Ilé Ọjà in Victoria Island and Opebi are redefining the landscape of luxury living in Lagos. Under her leadership, Abumet Nigeria Limited has also quadrupled its earnings, and she sits on the board of Julius Berger, Nigeria’s construction behemoth, which generated a record N566.2 billion in revenue in 2024.
Purpose, power, and quiet generosity
Despite his empire and estimated net worth of $6.8 billion—making him the second-richest Nigerian and among the top five wealthiest individuals in Africa—Adenuga remains strikingly private. Unlike many high-profile billionaires, he does not court the media. Instead, his actions speak. His philanthropic work, carried out quietly but consistently, includes donations of N1.5 billion during the COVID-19 pandemic, $3.8 million to victims of Niger Delta floods in 2012, and more than $20 million annually channeled into education and sports. His foundation offers scholarships to bright but underprivileged students, a cause close to the heart of a man who once drove cabs just to stay in school.
His properties—from the opulent “Bellissima” mansion on Banana Island to homes in London, Accra, and Johannesburg—are architectural marvels, yet they pale in comparison to the infrastructure of goodwill and employment his companies have built across Africa. The spirit that drove him to study business while driving a taxi, that enabled him to invest nine-figure sums in oil blocks against all odds, and that disrupted Nigeria’s telecom space, remains unbroken.
At 72, Mike Adenuga is not just a billionaire or a tycoon—he is an institution. His legacy is written not only in balance sheets but in lives transformed. He is the embodiment of African resilience, proof that greatness is born not of privilege, but of purpose. From the back seat of a yellow cab to the top tiers of global wealth, Adenuga’s journey is a symphony of bold choices and unwavering belief. Seventy-two years of greatness indeed—and counting.
