Larry Ellison Bio
Lawrence Joseph Ellison (born August 17, 1944) is an American businessman and entrepreneur who co-founded Oracle Corporation in 1977. He served as Oracle’s chief executive officer for nearly four decades before stepping aside in 2014, and he currently serves as the company’s executive chairman and chief technology officer. Under his leadership, Oracle grew into one of the largest enterprise software companies in the world, specializing in database management systems and cloud services.
According to Forbes, as of early 2026, Ellison’s estimated net worth was about $192 billion, placing him among the wealthiest people in the world. On September 10, 2025, a sharp rise in Oracle’s share price briefly pushed his estimated net worth to roughly $393 billion, making him the richest person in the world for a short time. He is also widely known for his personal investments, philanthropy, and ownership of about 98 percent of the Hawaiian island of Lānaʻi.
Early Life and Background
Lawrence Joseph Ellison was born on August 17, 1944, in New York City. His biological mother was Florence Spellman, and his biological father was an Italian-American United States Army Air Corps pilot. After Ellison contracted pneumonia at nine months old, his mother gave him to her aunt and uncle, Louis Ellison and Lillian Spellman Ellison, who adopted him and raised him in Chicago. Ellison did not meet his biological mother again until he was 48 years old.
Ellison grew up in Chicago’s South Shore neighborhood, then a middle-class area. He remembers his adoptive mother as warm and loving, while he viewed his adoptive father as distant and unsupportive. Louis Ellison had made a small fortune in Chicago real estate before losing it during the Great Depression, and he had chosen the family name to honor Ellis Island, his point of entry into the United States. Ellison was raised in a Reform Jewish household and attended synagogue regularly, although he later described himself as a religious skeptic and refused a bar mitzvah celebration at age 13.
He attended South Shore High School in Chicago and was admitted to the University of Illinois at Urbana–Champaign, where he initially studied pre-medical subjects and was named science student of the year. After his adoptive mother died, he withdrew without taking final exams in his sophomore year. He then spent the summer of 1966 in California before enrolling at the University of Chicago, where he studied physics and mathematics for one term and first encountered computer design. Ellison left both universities without earning a degree and later moved to Berkeley, California, where he began working as a computer programmer.
Path to Founding Oracle
After leaving the University of Chicago, Ellison moved to Berkeley and began his career as a computer programmer for several companies in the Bay Area. During the 1970s, he worked briefly at Amdahl Corporation before joining Ampex Corporation, where he led a project that built a database for the Central Intelligence Agency under the code name “Oracle.” That project gave him hands-on experience with relational database systems and exposed him to the ideas of Edgar F. Codd, whose research on relational data models shaped his thinking.
In 1977, Ellison joined two colleagues from Ampex, Ed Oates and Bruce Scott, at a small startup called Software Development Laboratories that had been founded by his former Ampex supervisor, Bob Miner. Each founder contributed about $2,000, with Ellison putting up $1,200 of his own money. Although he had strong technical skills, the group decided that Ellison would run sales while the others focused on engineering. In 1979, the company renamed itself Relational Software, Inc., and the initial release of its database was called Oracle version 2; there was no version 1. By 1983, the company had officially become Oracle Systems Corporation, named after its flagship product.
Larry Ellison Career
Early Career at Oracle (1977–1994)
Oracle’s first major product was its relational database, which was designed to work with IBM’s System R framework. After IBM refused to share its error codes, Oracle built its own path to compatibility. In 1990, Oracle laid off about 10 percent of its workforce, roughly 400 people, because the company was losing money. The trouble came from an “up-front” sales strategy in which sales staff booked future license sales in the current quarter to boost their bonuses. When those future sales failed to arrive, Oracle had to restate its earnings twice and settle class-action lawsuits, an episode Ellison later called “an incredible business mistake.”
Even as Oracle struggled financially, the relational database market was expanding. Ellison was named Entrepreneur of the Year by Harvard University in 1990, an early sign of the recognition he would receive throughout his career. By the mid-1990s, Oracle had survived its early turbulence and positioned itself for steady growth.
Database Wars and Industry Dominance (1994–2010)
From 1994 to 1997, Ellison’s biggest rival was Informix and its chief executive, Phil White. Their rivalry played out on the front pages of Silicon Valley business news. In April 1997, Informix announced a major revenue shortfall and earnings restatements, and White eventually went to prison. Ellison was also made a director of Apple Computer in 1997 after Steve Jobs returned to the company, and he served on that board until 2002.
After Oracle’s competitors stumbled, the company enjoyed a period of dominance in the relational database market. Ellison became one of the highest-paid executives in the United States during this era. In 2005, he settled a long-running insider trading lawsuit by agreeing to pay $100 million to charity in Oracle’s name, and his total compensation in some years exceeded $60 million. In April 2009, after a bidding contest with IBM and Hewlett-Packard, Oracle announced its intent to buy Sun Microsystems, a deal it completed in January 2010 after receiving regulatory approval. That acquisition gave Oracle control of the popular MySQL open source database and marked a major expansion of its technology portfolio.
Executive Chairman Era (2014–Present)
In September 2014, Ellison stepped down as CEO of Oracle and appointed Mark Hurd and Safra Catz as co-CEOs. He took on the roles of chief technology officer and executive chairman, focusing on product strategy and long-term technology direction. In November 2016, Oracle bought the cloud software company NetSuite for $9.3 billion, a deal in which Ellison had a personal financial interest. He also became a director of Tesla in December 2018 after buying 3 million shares, though he left that board in August 2022.
By the mid-2020s, Ellison remained deeply involved in Oracle’s push into cloud computing and artificial intelligence. On September 10, 2025, a surge in Oracle’s share price briefly made him the wealthiest person in the world, with an estimated net worth of $393 billion. In August 2025, his family trust provided funding for the merger of Paramount Global with his son David’s Skydance Media, leaving the trust as the largest shareholder in the new company.
Notable Events and Milestones
Ellison’s most dramatic public moment outside of business came in the 2010 America’s Cup, when his sailing team, BMW Oracle Racing, won the 33rd America’s Cup in Valencia, Spain, becoming the first challenger to win a “deed of gift” match. In 2013, his Oracle Team USA completed what has been called “one of the greatest comebacks in sports history,” overcoming an 8–1 deficit to defeat Emirates Team New Zealand 9–8 in the 34th America’s Cup. In 2010, he also made a brief cameo in the film Iron Man 2.

In 2013, he was inducted into the Bay Area Business Hall of Fame, and in 2024, he was named one of the 100 most influential people in the world by Time magazine.
Other Achievements
Beyond his main career at Oracle, Ellison co-founded SailGP in 2019 with Russell Coutts, an international sailing series using F50 foiling catamarans. He has also funded medical, academic, and charitable causes, including the Lawrence J. Ellison Institute of Technology, and he has signed The Giving Pledge, committing to give away the majority of his wealth.
