Early Life and Education
Larry Ellison was born in the Bronx, New York City, in 1944 to a single mother and never knew his biological father. At just nine months old, he was sent to live with his aunt and uncle in a modest South Side Chicago apartment.
His adoptive father, a government clerk, believed Ellison would amount to nothing—a sentiment Larry would spend a lifetime disproving.
Ellison attended the University of Illinois and later the University of Chicago but dropped out before graduating. While he never earned a formal degree, his exposure to computer programming and mathematics during this time laid the groundwork for a legendary tech career.
Career Beginnings
Ellison moved to Berkeley, California, during the tech boom of the 1970s. After brief stints at Ampex and other tech firms, he became fascinated by relational database models described in a 1970 paper by IBM researcher Edgar F. Codd.
In 1977, with just $2,000 of his own money and $1,200 from partners Bob Miner and Ed Oates, Ellison co-founded Software Development Laboratories—the precursor to Oracle.
The company’s big break came when it won a contract to build a database system for the CIA, codenamed “Oracle.” By 1982, the firm had adopted the same name and began its rise to dominance in enterprise software.
Rise to Wealth
Oracle went public in 1986, making Ellison an instant multimillionaire. Throughout the 1990s and early 2000s, Oracle grew aggressively by selling high-performance database software to corporations, governments, and financial institutions.
By the early 2000s, Ellison was consistently one of the wealthiest individuals in the United States. Under his leadership, Oracle expanded its footprint through a series of major acquisitions: PeopleSoft, Siebel Systems, BEA Systems, and Sun Microsystems.
As of 2025, Ellison remains Oracle’s CTO and Chairman, with the company now a leader in cloud infrastructure, AI-enhanced databases, and cybersecurity.
His personal net worth stands at $147 billion, placing him consistently among the top 10 wealthiest individuals globally.
How He Made His Fortune
Ellison built his fortune by providing critical software infrastructure to businesses and governments—databases that power everything from financial transactions to national defense.
Oracle’s model shifted over time from traditional software licensing to a modern cloud computing platform, allowing the company to compete with Amazon Web Services, Microsoft Azure, and Google Cloud.
His wealth is primarily tied to his 42% stake in Oracle. He also owns substantial holdings in Tesla, where he served on the board, and various private ventures in health tech and biotech.

Philanthropy and Social Impact
While Ellison was once criticized for his limited philanthropic engagement, he has since increased his giving. In 2010, he signed The Giving Pledge, committing to donate the majority of his wealth during his lifetime.
Through the Lawrence Ellison Foundation, he funds research into aging, global public health, and education reform. He has also donated hundreds of millions toward cancer research, particularly at USC and Stanford.
Ellison is known for favoring science-driven, results-oriented philanthropy over high-profile charitable branding.
Personal Life and Interests
Larry Ellison has been married and divorced four times and has two children, Megan and David, both active in the film industry.
He owns a sprawling estate in Woodside, California, designed like a 16th-century Japanese imperial palace, and a vast portion of Lanai, Hawaii, where he is developing a model for sustainable tourism, agriculture, and wellness.
Ellison is a passionate yachtsman—his Oracle Team USA won the America’s Cup in 2010 and 2013. He also holds interests in aviation, real estate, and competitive sailing.
Business Philosophy and Strategies
Ellison is known for his combative style, relentless ambition, and unmatched work ethic. His leadership is marked by aggressive acquisitions, competitive pricing strategies, and a refusal to be outdone by rivals like IBM, SAP, and Microsoft.
He believes in vertical integration—controlling everything from hardware (through Oracle’s Sun acquisition) to cloud infrastructure. He has also been a vocal advocate for AI integration in enterprise software, saying in 2024 that “AI will be the foundation of the modern digital corporation.”
Challenges and Controversies
Oracle has faced multiple lawsuits over antitrust practices, software licensing disputes, and alleged discrimination. In 2020, the company was criticized for its pursuit of a contract with the U.S. government for COVID-19 data aggregation without clear privacy guidelines.
Ellison himself has occasionally courted controversy for his political affiliations, including fundraising events and statements aligned with libertarian and conservative causes.
His leadership style—forceful, visionary, at times polarizing—has both fueled Oracle’s rise and drawn criticism from opponents and former employees.
Current Focus and Future Plans
As of May 2025, Ellison is focused on scaling Oracle’s autonomous database and AI-powered cloud infrastructure, positioning the company as a next-generation enterprise tech leader.
He is also investing in precision medicine, climate adaptation technologies, and energy-efficient server farms on Lanai.
Despite being in his 80s, Ellison remains active in Oracle’s strategy and product development—regularly appearing at keynotes and industry forums.
He has stated he has “no intention of retiring,” calling Oracle “the ultimate intellectual adventure.”
