Over a dozen of Dallas-Fort Worth's illustrious billionaires have made the cut on the new Forbes 400, a list of the 400 richest people in the United States for 2024.

Released on October 1, the Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies.

According to the report, America's elite class is now worth $5.4 trillion collectively, which is a $1 trillion jump since 2023.

“The Forbes 400 is richer than ever, and it’s harder than ever to be one of the 400 richest people in America," said Forbes senior editor Chase Peterson-Withorn in a press release.

In all, 43 Texas billionaires made the list.

Austin resident Elon Musk ranks No. 1 nationally for the third time, with a net worth of $244 billion. Despite ranking at the top of the list this year, Musk's net worth has actually dropped by $7 billion since 2023.

Walmart heiress Alice Walton of Fort Worth is the third-richest Texan, as well as the wealthiest person in DFW and the wealthiest woman in America. According to Forbes' list, Walton has a net worth of $89.2 billion, which has risen significantly from her 2023 net worth of $56.7 billion. Walton, 74, is the only daughter of Sam Walton, who opened the first Walmart store in 1962.

New to the list is Lyndal Stephens Greth, who is the chairman of Midland-based oil company Endeavor Energy Resources and daughter of the late Autry Stephens, who founded the company. Forbes estimates Greth's net worth as $32.3 billion, and lists Dallas as her city of residence. She is the second wealthiest person in Dallas-Fort Worth, and the 28th most affluent person in the U.S.

Greth became chairman of Endeavor Energy Resources after Stephens died in August 2024. In a deal that closed in September, Endeavor Energy Resources was sold to Midland-based Diamondback Energy for an estimated $26 billion in stock and cash.

"Endeavor is one of the largest private oil producers in the U.S., generating some 327,000 barrels of oil equivalent per day," Forbes wrote in Greth's profile. "The company has the rights to drill on more than 500,000 acres in the U.S., mainly in Texas."

The third-richest person in DFW is Koch Inc. co-owner Elaine Marshall and family. Marshall, 82, has an estimated net worth of $28.3 billion — a substantial hike from her last reported net worth of $8.8 billion in 2014. She is the fifth wealthiest Texan and the 35th richest person in the U.S.

"Elaine Marshall owns an estimated 16 percent of $125 billion (sales) conglomerate Koch, Inc. (formerly Koch Industries) with her two sons," Forbes says. "She inherited her stake from husband E. Pierce Marshall (d. 2006), whose father J. Howard Marshall II (d. 1995) was an early partner of founder Fred Koch (d. 1967)."
