At 81 Years Old, Larry Ellison Conquers the Summit: How a Silicon Valley Visionary Reinvented Himself with AI

September 10, 2025, will be remembered in the annals of business technology. On that date, Larry Ellison, the octogenarian co-founder of Oracle, crossed a threshold few reach in their later decades: he became the world’s richest man. With a fortune reaching $393 billion, he overtook Elon Musk, who had previously reigned unchallenged with $385 billion. It wasn’t a gradual change but an almost meteoric transformation that added more than $100 billion to his wealth in just one day. At an age when many privileged individuals retire to enjoy their accumulated riches, Ellison proves that true ambition knows no age.

From abandonment to wealth: how Larry Ellison built the Oracle empire

Ellison’s story begins far from the glamour of Silicon Valley. Born in 1944 in the Bronx, New York, he was abandoned by his biological mother at nine months old. Raised by his aunt in Chicago, he grew up in a modest family, the adopted son of a government employee. Although he enrolled at the University of Illinois, he did not complete his studies. After his adoptive mother’s death during his second year, he dropped out. He later attempted again at the University of Chicago but only stayed for one semester. However, his true education would come far from universities.

For several years after leaving school, Ellison wandered across the United States searching for his path. His destiny changed when he arrived in Berkeley, California, where he sensed something different: an atmosphere infused with intellectual freedom and emerging technology. “People there seemed freer and smarter,” he would recall years later. In the early 1970s, he got a job at Ampex Corporation, a company specializing in audiovisual storage. There, he participated in a project that would define his career: designing a revolutionary database system for the CIA to manage information efficiently. This project, codenamed “Oracle,” showed him the commercial potential of data management technology.

In 1977, at age 32, he saw his opportunity. Alongside Bob Miner and Ed Oates, his colleagues from Ampex, he invested in founding Software Development Laboratories. Ellison contributed $1,200 of the initial $2,000. The vision was bold: create a universal commercial database system, which they simply called “Oracle.” What distinguished Ellison was not inventing relational database technology but being the first to see its commercial potential and risking his entire fortune to conquer the market. In 1986, Oracle went public on Nasdaq, becoming a phenomenon in enterprise software.

For more than four decades, Ellison held nearly every executive role in the company, acting as the strategic compass that guided Oracle through radical transformations. From 1978 to 1996, he was president; later, he would serve as chairman multiple times. Even a surfing accident in 1992 that nearly cost him his life did not stop him. In 2014, although he formally resigned as CEO, he remains as executive chairman and chief technology officer, roles he still holds today.

AI was his late-blooming ticket: how Oracle resurged in the era of artificial intelligence

For years, Oracle was plagued by the same uncomfortable questions: was it falling behind in the cloud computing era? Giants like Amazon AWS and Microsoft Azure seemed to have won the race. But in the most spectacular transformation of his late career, Larry Ellison strategically positioned Oracle in the expanding wave of generative artificial intelligence.

The catalyst was September 10, 2025, when Oracle announced a colossal partnership with OpenAI: a five-year, $300 billion contract, along with three other significant agreements. The market responded with epic enthusiasm: shares soared over 40% in a single day, the highest growth since 1992. Suddenly, Oracle shifted from being a “legacy software company” to one of the leading providers of AI infrastructure.

The strategy was meticulous. In summer 2025, the company underwent a radical restructuring: laying off several thousand employees from traditional software and hardware divisions, while simultaneously investing heavily in data centers and AI infrastructure. It was not delay but repositioning. Thanks to its historic strength in robust databases and access to enterprise clients, Oracle had exactly what the world needed in the AI explosion: unprecedented storage, processing, and data management capacity.

Ellison, who had already witnessed how technology redefined industries, recognized that AI needed data infrastructure more than ever. What for others seemed the sunset of Oracle was, for him, an opportunity for a second business youth.

Extreme self-discipline and boundless passion: the paradoxical lifestyle of an 81-year-old entrepreneur

Larry Ellison embodies fascinating contradictions. He owns 98% of Lanai Island in Hawaii, several California mansions, and world-class yachts—symbols of almost immeasurable luxury. Yet, he lives under a regime of self-discipline few would dare to maintain. In later interviews, former executives revealed that during the 1990s and 2000s, Ellison dedicated several hours daily to rigorous physical exercise. He practically did not consume sugary drinks, preferring water and green tea, while meticulously controlling every aspect of his nutrition.

At 81, the results are clear: Ellison describes himself as “twenty years younger than his peers,” with energy that defies his chronological age. His secret is not a magic elixir but the intersection of the freedom to pursue passions and relentless discipline.

Water and wind are his recurring obsessions. Although a surfing accident in 1992 nearly took his life, he never stopped seeking that adrenaline rush. He eventually channeled this passion into sailing. In 2013, Oracle Team USA, generously sponsored, executed an epic comeback in the America’s Cup, winning one of the most legendary trophies in water sports history. Its impact was so significant that in 2018, he founded SailGP, a league of ultra-fast catamarans that has attracted celebrities like Anne Hathaway and elite athletes like Mbappé as investors.

Tennis is another passion he transformed into a legacy. He revitalized the Indian Wells tournament in California, elevating it to the status of the “fifth Grand Slam.” For Ellison, sport is not merely entertainment but a fundamental tool for his longevity and vitality.

Regarding his personal life, Ellison has gone through four marriages and numerous publicly known relationships. In 2024, he discreetly married Jolin Zhu, a Chinese woman 47 years his junior, a news that leaked through a donation announcement from the University of Michigan. According to reports from the South China Morning Post, Zhu was born in Shenyang, China, and graduated from an American institution. Some joke on social media that Ellison loves surfing as much as marriage, and both passions seem equally attractive to a man who has never accepted the limitations age imposes.

Power, philanthropy, and legacy: how Larry Ellison expands his empire beyond Silicon Valley

Ellison’s wealth has long transcended the personal realm to become a family empire. His son, David Ellison, recently orchestrated the acquisition of Paramount Global, the corporate parent of CBS and MTV, for $8 billion, with $6 billion financed by family backing. This transaction marks the Ellison entry into Hollywood, linking technology and entertainment in an unprecedented power structure.

In the political arena, Ellison also wields significant influence. A long-time Republican donor, in 2015 he funded Marco Rubio’s presidential campaign; in 2022, he contributed $150 million to the Super PAC of South Carolina senator Tim Scott. In January 2025, he appeared at the White House alongside SoftBank CEO Masayoshi Son and OpenAI CEO Sam Altman to announce the deployment of a $500 billion AI data center network. Oracle’s technology would be central, transforming this project into an extension of both commercial and geopolitical power.

Regarding philanthropy, in 2010 Ellison signed the “Giving Pledge,” publicly committing to donate at least 95% of his fortune. But unlike Bill Gates or Warren Buffett, he rarely participates in collective initiatives. In an interview with the New York Times, he revealed: “I value my solitude and do not wish to be influenced by external ideas.” In 2016, he donated $200 million to the University of Southern California to establish an oncology research center. Recently, he announced that a substantial part of his wealth will fund the Ellison Institute of Technology, developed in collaboration with Oxford University, dedicated to medical, agricultural, and climate research.

In his own words on social media: “We want to design a new generation of life-saving medicines, build low-cost agricultural systems, and develop clean, efficient energy for humanity.” His philanthropy is intensely personal; he does not seek to join his billionaire peers but aims to independently craft a future reflecting his unique vision.

The legend continues: how an octogenarian keeps writing his story

At 81, Larry Ellison has finally reached the pinnacle: becoming the richest man in the world. His journey is a story of perpetual reinvention. From an abandoned orphan working on a CIA project, to building a global database empire, dropping out of conventional universities, and with a prescient vision, positioning himself strategically in the wave of artificial intelligence—achieving what many would call an “impossible comeback.”

Wealth, political power, successive marriages, extreme sports, idiosyncratic philanthropy: Larry Ellison’s life has never lacked drama nor stayed far from controversy and admiration. He is the perpetual rebel of Silicon Valley: stubborn, competitive, and unwavering in his convictions. Though the throne of the world’s richest may change again, at least for now, Ellison has demonstrated that old tech titans still set the rules in an era transformed by AI. His story is not just a business biography but a testament that true wealth, at any age, lies in the ability to reinvent oneself.
