If it’s good to be king than it’s even better to be a Koch. The famous billionaire brothers won the top spots yet again on Wealth-X’s wealthiest U.S. oil tycoon list.
David Koch, 75, took the top spot with a net worth of $47.9 billion, up 14 percent from last year.
Older brother Charles Koch, 79, came in at a close second with a net worth of $47.8 billion, a 14 percent spike over last year.
Continental Resources CEO Harold Hamm took the third spot despite a contentious $975 million discover settlement and falling oil prices that took a 36 percent chunk out of his fortune.
According to Wealth-X, Hamm is currently worth $11.8 billion, a $6.7 billion loss from last year.
Richard Kinder, co-founder of transportation giant Kinder Morgan, rose to the fourth spot with a net worth of $11.6 billion, a 26 percent jump since last year.
George Kaiser, chairman of BOK Financial Corporation, slid down to the fifth spot after his network fell to $10.6 billion, down from $13.3 billion last year.
Elaine Marshall, a 15 percent stakeholder and board member at Koch Industries, was the wealthiest woman on the list, with her $8.8 billion fortune landing her in the sixth spot.
Energy Transfer Partners CEO Kelcy Warren made his debut on the list at the seventh spot with a net worth of $7 billion.
The children of late Enterprise Products Partners co-founder Dan Duncan rounded out the top three spots.
Milane Frantz was knocked down to the eighth spot after her net worth fell 8 percent drop to $5.7 billion and was tied with fellow Duncan heiress Randa Williams.
Scott Duncan marked his entrance onto the list by rounding out the top ten with his $5.7 billion fortune.
