What is Scott Duncan's net worth?

Scott Duncan is an American businessman who has a net worth of $9 billion. Scott Duncan is the youngest child of the late energy tycoon Dan Duncan, who built Enterprise Products Partners into one of the largest pipeline and energy companies in the United States. Along with his three sisters, Randa, Milane (who passed away in 2015), and Dannine, Scott inherited a multibillion-dollar stake in the family empire after his father's death in 2010.

Dan Duncan founded Enterprise Products in 1968 with just a few thousand dollars and a single truck. Over the following decades, he expanded it into a massive midstream energy company with pipelines, storage facilities, and processing plants that handle natural gas, crude oil, and petrochemicals. By the time of his death, Enterprise Products Partners had become one of the most important energy infrastructure companies in the country, and Dan Duncan was one of the wealthiest men in America, with a fortune estimated at more than $9 billion.

When Dan Duncan passed away, the transfer of wealth to his children coincided with a one-year lapse in the U.S. estate tax. That rare circumstance meant that the Duncan heirs inherited their father's fortune without having to pay billions in taxes that would otherwise have been due. The four siblings each became instant billionaires, thrust into the spotlight as some of the wealthiest young people in the world.

Scott Duncan has maintained a lower profile than his sisters, who are more directly involved with the operations and governance of the family business. While he benefits from his substantial holdings in Enterprise Products Partners, Scott has largely stayed out of public view and does not play a day-to-day executive role in the company. Instead, he is known for managing his investments and maintaining privacy, in contrast to the visibility of many other billionaire heirs.

Enterprise Products remains one of the largest publicly traded partnerships in the U.S., with annual revenues in the tens of billions of dollars. The Duncan family continues to collectively hold significant ownership in the company, which underpins their vast wealth. Forbes consistently lists the Duncan heirs among the richest families in America, with Scott's fortune estimated around $9 billion.

Despite his immense wealth, Scott Duncan has managed to keep his personal life largely out of the public eye. He is not a prominent public philanthropist like some billionaires, nor has he sought media attention or high-profile ventures. His legacy is tied primarily to the remarkable rise of Enterprise Products, his father's vision, and the family's enduring place among America's richest dynasties.
