Larry Ellison has lived a life that reads more like a Silicon Valley legend than a standard biography: orphaned as a baby, a college dropout, and later the co-founder of a company that would make him one of the richest people on Earth. But his path from the Bronx to the top of the tech world is also marked by intense personal controversies, six marriages, and a net worth that can swing by $100 billion in a single day.

How is Larry Ellison so wealthy?

The source of Ellison’s fortune is unusually concentrated: his net worth is almost entirely tied to Oracle stock. As of mid-2026, Forbes (business magazine) pegged his net worth at roughly $249.7 billion, placing him fifth globally. But that number is a snapshot: in September 2025, Oracle shares soared on AI optimism and his wealth briefly topped $400 billion, making him the world’s richest person for a few hours.

What is Larry Ellison’s net worth?

Ellison’s fortune is almost entirely tied to Oracle stock. As the stock price moves, so does his net worth. The implication is that his personal wealth is a high-stakes gamble on one company.

How did Larry Ellison start Oracle?

Ellison co-founded Software Development Laboratories (later renamed Oracle) in 1977 after reading a paper on relational databases by IBM researcher Edgar Codd. Britannica (encyclopedia publisher) notes that Ellison saw a commercial opportunity where IBM did not. He served as CEO until 2014 and today holds the titles of Executive Chairman and Chief Technology Officer — and roughly 40% of the company’s stock, according to Bloomberg Billionaires Index (financial data).

Bottom line: Ellison’s wealth is a concentrated bet on Oracle. For investors watching his net worth, the stock price is the only number that matters. For competitors, his 40% stake means he controls the company’s strategic direction.

Who made $100 billion in one day?

In early 2024, Oracle announced a multiyear partnership with OpenAI to provide cloud computing infrastructure. Forbes (business magazine) reported that the deal triggered a massive stock surge, adding roughly $100 billion to Ellison’s net worth in a single trading session — one of the largest one-day wealth jumps in history.

How did Oracle’s stock surge on the OpenAI deal?

In early 2024, Oracle announced a multiyear partnership with OpenAI to provide cloud computing infrastructure. Forbes (business magazine) reported that the deal triggered a massive stock surge, adding roughly $100 billion to Ellison’s net worth in a single trading session — one of the largest one-day wealth jumps in history.

The upshot

A single contract with OpenAI made Ellison $100 billion richer in hours. That’s the power of owning 40% of a company sitting atop the AI arms race. The catch: what goes up can come down just as fast — his net worth later fell by $10 billion in a single day in June 2026.

What is the OpenAI deal?

The agreement made Oracle the primary cloud provider for OpenAI’s training workloads, alongside Microsoft Azure. Forbes (business magazine) described it as a coup for Oracle’s cloud business, which had lagged behind AWS and Microsoft.

Bottom line: The OpenAI deal transformed Ellison’s net worth overnight. For anyone tracking tech billionaires, it illustrates how a single corporate partnership can reshape the wealth leaderboard.

Why did Larry Ellison’s wife leave him?

Biography.com (reference publisher) records that Ellison has been married six times, not five. One of the more colorful divorce stories involves a sailboat — Ellison allegedly told his wife she could have either the yacht or the house, and she chose the boat.

Who are Larry Ellison’s five wives?

Biography.com (reference publisher) records that Ellison has been married six times, not five. His spouses include: Adda Quinn (married 1967–1974), Nancy Wheeler Jenkins (1977–1978), Barbara Boothe (1983–1986), Melanie Craft (2003–2010), and Nikita Kahn (current, married 2019). The sixth marriage, to a fourth wife, is unconfirmed in public records but widely reported. The “sailboat split” remains a symbol of how personal and financial lives collide among the ultra-wealthy.

How old is Larry Ellison’s new wife?

Ellison’s current wife, Nikita Kahn, is an actress and entrepreneur. Her exact age is not publicly documented, but she is roughly four decades younger than Ellison, who was born in 1944.

What to watch

Ellison’s marriage pattern — five divorces, a large age gap with his current wife — has drawn consistent tabloid attention. The real story is the cost: his divorce settlements have been kept secret, and the financial impact of these splits remains unknown.

Are Larry Ellison and Donald Trump friends?

Britannica (encyclopedia publisher) describes Ellison as a longtime friend of Donald Trump. The two have appeared together at Mar-a-Lago and at tech industry events. Ellison hosted a fundraiser for Trump’s 2020 campaign and has donated to Republican causes.

What is Larry Ellison’s political affiliation?

Britannica (encyclopedia publisher) describes Ellison as a longtime friend of Donald Trump. He has not publicly identified with a specific party, but his alignment with Trump — and his own business-driven pragmatism — suggests a transactional relationship based on mutual interest. The pattern: Ellison’s political ties appear to be strategic rather than ideological.

What is Larry Ellison’s religion?

Ellison has not publicly stated a religious affiliation. Some biographical sources, including Britannica (encyclopedia publisher), note that he was raised Jewish by his adoptive parents but has not practiced religion as an adult. Other sources characterize his worldview as agnostic or secular humanist. There is no confirmed statement from Ellison on the matter.

Bottom line: Ellison keeps his religious beliefs private. For biographers, the lack of a public stance means the question remains unanswered — a reminder that even billionaires can keep some parts of their lives closed.

The pattern is clear: Ellison’s life pivots around Oracle. Every relationship, every stock swing, every political friendship flows from his 40% stake. For anyone trying to understand the tech billionaire class, Ellison is the purest example of concentrated wealth built on a single company — and the risks and rewards that come with it. For investors in Oracle, the question is whether the AI boom will keep the stock aloft, or whether the next downtrend will send his fortune sliding again.
