Brad Duke went from Powerball millionaire to billionaire by investing
Powerball winner Brad Duke billionaire via investing

Brad Duke, a personal trainer from Star, Idaho, won a $220 million (£165 million) Powerball jackpot in 2005. Rather than spending his winnings on luxury items, he chose to invest wisely, turning his million-dollar win into a billion-dollar fortune within 12 years.

Winning and Wise Choices

Duke did not immediately splurge on sports cars or a mansion. Instead, he decided to make his money work for him. In 2007, he outlined his investment plan: $45 million into low-risk ventures, $35 million into high-risk assets, and $1.3 million into the Duke Family Foundation. He built a team of trusted financial advisors to help him reach his goal of being "worth about 10 times as much" as his initial win.

Within 12 years, Duke's net worth reached $1 billion (£750 million), a feat achieved through disciplined investing rather than frivolous spending.

Lifestyle and Advice

While Duke avoided major splurges, he did make some memorable purchases. He financed a trip to Tahiti for 17 friends and bought himself more than a dozen new bikes. He continued working as a manager and cycling instructor at Gold's Gym for over a year after his win, looking back fondly on his time there. "I really didn't think things could get better for me," he told KTVB in 2022. "I remember thinking that and within that week, this happened."

Duke reflected on the responsibility of winning, saying, "If you accept that cheque, you accept an amazing responsibility to yourself and whomever you decide to include in it. I was quiet about winning for a month before I decided to come out. During that time, I was getting as much research as I could on existing lottery winners and what their stories were." He noted that most winners "lose all the money within a short amount of time."

Method and Smaller Wins

Duke was not a casual gambler; he developed an intricate mathematical system for picking his numbers. Before hitting the jackpot, he had already won smaller amounts, such as $150 or $500.
