Larry Ellison ranks among the world's wealthiest individuals, but his financial picture comes with an unusual twist. The Oracle co-founder has accumulated substantial debt by borrowing heavily against his stake in the software company he founded nearly 50 years ago, a strategy that sets him apart from most tech billionaires.

Ellison's borrowing has funded an extravagant lifestyle that includes multiple superyachts and ownership of 98% of an island in Hawaii. He recently guaranteed more than $40 billion in debt related to the Warner Bros. Discovery transaction, positioning him as potentially one of the most indebted wealthy individuals globally.

Unlike many tech founders who diversify their holdings, Ellison has maintained a significant position in Oracle. His son David Ellison has also moved into Hollywood, further expanding the family's entertainment interests beyond the tech sector.

The arrangement illustrates how ultra-wealthy individuals can leverage concentrated stock positions to access liquidity without selling shares, though it also exposes them to significant market risk if their company's stock declines.
