I found Larry Ellison's story fascinating, especially seeing how this guy managed to bounce back at 81 years old. Last September, he officially overtook Elon Musk to become the richest man in the world – a turnaround no one really expected. His fortune skyrocketed by over 100 billion dollars in a single day after Oracle announced huge contracts, including a 300 billion dollar deal with OpenAI. The stock price jumped 40%, the biggest gain since 1992.

What really interests me is how Ellison navigated technological transitions. The guy co-founded Oracle in 1977 with barely 2,000 dollars in his pocket – including 1,200 of his own – and built an empire around databases. For decades, Oracle dominated this market without competition. But when cloud computing arrived, the company was caught up by AWS and Azure. Except Ellison saw where the real money was heading: AI infrastructure. In summer 2025, Oracle laid off thousands of employees in traditional software divisions to redirect everything toward data centers and AI. And bam, they are now at the heart of a frenzied demand.

What makes this story even more interesting is the person himself. Ellison is not just a billionaire accumulating wealth. The guy owns 98% of Lanai Island in Hawaii, nearly died surfing in 1992 but that didn’t stop him – he took up sailing afterward and won the America’s Cup with his team in 2013. He also launched SailGP. Tennis is another obsession – he transformed the Indian Wells tournament into a major event now called the fifth Grand Slam.

On a personal level, Ellison married Jolin Zhu in 2024 – a woman 47 years younger than him. We found out through a University of Michigan document mentioning Larry Ellison and his wife Jolin’s donation. Jolin was born in Shenyang, China, and studied in Michigan. She’s his fourth wife, and honestly, that shows that at 81, this guy has no intention of slowing down.

Ellison’s self-discipline is legendary. Between 1990 and 2000, he trained for hours every day, only drank water and green tea, and strictly controlled his diet. A former executive mentioned that he looks twenty years younger than his peers. It’s not just genetics; it’s a conscious choice.

On the philanthropic side, he signed the Giving Pledge in 2010, committing to give away 95% of his fortune, but unlike Gates and Buffett, he acts solo. He donated 200 million dollars to USC for cancer research, and recently redirected part of his wealth toward the Ellison Institute of Technology in partnership with Oxford to study health, agriculture, and clean energy.

What truly fascinates me is how Ellison understood before everyone else that real value lies in infrastructure, not just software. Oracle has always been behind on hype trends, but when AI exploded, they were already positioned in the right places. And now, at 81, he finds himself at the top of the billionaire rankings. Not bad for a guy who grew up an orphan.
