Larry Ellison: Life, Career, Net Worth of Oracle CTO and Cofounder

Larry Ellison’s Rise to Wealth and Influence

Larry Ellison, the founder and chief technology officer of Oracle, currently holds the position of the fifth-richest individual worldwide, boasting a net worth of $238 billion, as reported by the Bloomberg Billionaires Index. His financial journey in 2025 was characterized by significant fluctuations, including a brief period when he became the richest person globally with a net worth of $393 billion in September. This surge was largely driven by a spike in Oracle’s stock following impressive quarterly results and an optimistic forecast for its AI-driven cloud services. However, by the end of 2025, Ellison experienced a substantial $25 billion decline in his wealth due to a more than 11% drop in Oracle’s shares, which was attributed to disappointing earnings. This decline on December 12 marked one of the most significant single-day losses of the year, resulting in Tesla’s Elon Musk reclaiming the title of the world’s wealthiest individual.

Ellison’s Vision for Artificial Intelligence

As Oracle, like many other technology leaders, heavily invests in artificial intelligence, Ellison is at the forefront of these initiatives. His current endeavors include the establishment of data centers for clients such as OpenAI. Since founding Oracle in 1977, Ellison has maintained his status as a powerhouse in Silicon Valley, even while residing in Hawaii.

Early Life and Education

Born in the Bronx on August 17, 1944, to a single mother, Florence Spellman, Ellison spent his formative years in the South Side of Chicago. He briefly attended the University of Illinois but left after the death of his adoptive mother. A short stint at the University of Chicago also ended prematurely. In 1966, at the age of 22, he relocated to Berkeley, California, near the burgeoning tech scene of Silicon Valley. During this time, he held various jobs, including positions at Wells Fargo and Amdahl, where he acquired essential programming skills.

The Founding of Oracle

In 1977, Ellison established Oracle with an initial investment of $2,000, motivated by IBM scientist Edgar F. Codd’s groundbreaking concept of relational databases. The company’s first product was named Version 2. After a brief period as Relational Software Inc., the company rebranded to Oracle Systems in 1982 and went public in 1986, generating $55 million in revenue. Although Oracle experienced rapid growth, it faced near bankruptcy in 1990 due to revenue miscalculations that led to financial losses and layoffs. By 1992, the release of Oracle7 restored the company’s fortunes. Throughout the 1990s, Oracle engaged in fierce competition with rivals like Informix and capitalized on the dot-com boom, providing database solutions to numerous startups. Flush with capital, Oracle embarked on an acquisition spree, acquiring PeopleSoft for $10.3 billion in 2005 and Sun Microsystems in 2010, which enabled the company to secure crucial technologies, including MySQL. In the same year, Ellison brought in Mark Hurd and Safra Catz, who later became co-CEOs. He stepped down as CEO in 2014 but continues to serve as chairman and chief technology officer.

Wealth and Lifestyle

As Oracle’s largest shareholder, Ellison has leveraged his wealth to lead a life filled with high-profile investments, philanthropy, and notable purchases. An avid yacht racer, he financially supported the BMW Oracle USA team that won the America’s Cup in 2010. He has also amassed a collection of luxury Richard Mille watches, each worth hundreds of thousands to millions of dollars. In 2009, he acquired the Indian Wells tennis tournament for $100 million, and in 2012, he purchased 98% of the Hawaiian island of Lanai, where he later established a wellness retreat and supported a farming startup. His real estate holdings extend to opulent properties in Malibu, Palm Beach, and Rhode Island. Ellison has a history of being an active investor, having been an early supporter of Salesforce and investing in Leapfrog and the infamous Theranos. One of his most successful investments was in NetSuite, where a $125 million investment in 1998 yielded a $3.5 billion return when Oracle bought the company in 2016. He served on Apple’s board in the late 1990s and joined Tesla’s board in 2018, resigning from that position in 2022.

Family Background

Ellison has two children: David and Megan. His daughter, Megan, is an Oscar-nominated film producer who founded Annapurna Pictures, known for producing acclaimed films such as “Zero Dark Thirty” and “American Hustle.” His son, David, also works in the film industry, running Skydance Media, which has produced popular movies, including “Terminator: Dark Fate” and installments of the “Mission: Impossible” series. After extensive negotiations in 2024, Skydance Media entered into a partnership with Paramount, creating Paramount Skydance, with David as CEO. The duo, who hold a controlling interest in Paramount, previously made a hostile bid for Warner Bros. Discovery, offering $30 per share in December 2025.

Philanthropic Efforts

Ellison committed to philanthropy by signing the Giving Pledge in 2010, promising to donate 95% of his wealth. His charitable contributions include a significant $200 million donation to a cancer center at USC in 2016, which has since been renamed the Ellison Institute of Technology. The institute announced plans for a campus in Oxford in 2023. He has also been active in the political arena during Donald Trump’s second term, participating in a press conference with tech leaders like Sam Altman of OpenAI and Masayoshi Son of SoftBank to announce Project Stargate, a collaborative initiative to invest up to $500 billion in AI infrastructure in the United States. Trump has referred to Ellison as a remarkable individual, praising his extensive influence and contributions.
