6 MD Billionaires Worth Combined $30B Make Exclusive Forbes 400

With a net worth of $908 billion, Elon Musk again tops the Forbes 400, a ranking of the nation’s wealthiest billionaires that includes Annette Lerner, the richest person in Maryland.

Forbes said Musk’s place at the top of its 45th annual Forbes 400 ranking shows “the wealth gap is widening, even among the ultra-rich.” Those on the ranking, released Tuesday, are worth a record $8 trillion, up from $6.6 trillion a year ago. Together, the 20 richest billionaires account for $4 trillion of the total, up from $970 billion from last year.

“Elon Musk’s trillionaire moment was short-lived, but the wealth controlled by the top 20 is massive,” Forbes said.

Billionaires on the list from Maryland are:

• No. 277 - Annette Lerner and family - $6.1B - Lerner Enterprises is among the largest real estate owners in the Washington, D.C., area. Ted Lerner died in February 2023, leaving Annette and her children as the heirs of his estate. Since 2006, the Lerners have owned the Washington Nationals baseball team. Ted passed control of the team to son Mark in 2018.
• No. 318 - Dan Snyder - $5.3B - Dan Snyder initially made his fortune with a marketing business, Snyder Communications, that he started as a college dropout. After taking the company public in 1996, Snyder sold it to French firm Havas for $2.1 billion in stock in 2000. In 1999, he bought the NFL's Washington Commanders for $750 million, borrowing $350 million. He sold the franchise for $6.05 billion in 2023.
• No. 325 - Mitchell Rales - $5.2B - Mitchell Rales and his brother Steven acquired a real estate investment trust in 1983 and merged it into the firm Danaher. Over the years, they acquired more than three dozen companies and turned Danaher into an industrial firm with nearly $25 billion in 2025 revenue. Rales is also a minority owner of the NFL's Washington Commanders.
• No. 380 - Theodore Leonsis - $4.5B - Theodore 'Ted' Leonsis is chairman and majority owner of Monumental Sports, which he founded in 2010. Monumental owns several sports teams and venues in Washington, D.C including the NBA's Wizards, the NHL's Capitals, the WNBA's Mystics and Capital One Arena.
• No. 380 - David Rubenstein - $4.5B - David Rubenstein is one of three billionaire founders of private equity firm Carlyle Group, which has roughly $485 billion in assets under management. Rubenstein cofounded Carlyle in 1987 with William Conway Jr. and Daniel D'Aniello. He now serves as non-executive co-chairman. He is also the controlling owner of the Baltimore Orioles, which he purchased with an investor group in 2024 for $1.75 billion.
• No. 396 - Jim Davis - $4.4B - Jim Davis cofounded Allegis Group, the largest staffing firm in the U.S. Davis launched Allegis (then called Aerotek) in 1983 with his cousin Steve Bisciotti, who is also a billionaire. Allegis now has offices on four continents and boasts an annual revenue of more than $14 billion.

Even with the list threshold rising to a record $4.4 billion — up from $3.8 billion in 2025 — strong financial growth allowed 34 newcomers to join it. Notably, a record 590 U.S. billionaires were “too poor to make the cut,” Forbes said.

Many of the 34 newcomers made their fortunes in artificial intelligence, including Cognition AI cofounder Steven Hao, six Anthropic cofounders and OpenAI cofounder Greg Brockman.

The AI sector has come under intense scrutiny in Congress this week as high-profile tech leaders push for federal safety regulations and a reduced pace of innovation. These warnings follow mounting concerns about existential risks posed by advanced AI systems, echoed in an essay by Anthropic CEO Dario Amodei and supported by xAI's Musk and OpenAI's Sam Altman.

The list includes 62 women, including 13 who are self-made. Alice Walton remains the richest American woman, while ABC Supply cofounder Diane Hendricks is the richest self-made woman.

Ten listees are younger than 40, up from four in 2025. The oldest is 97-year-old timber billionaire Archie Aldis Emmerson, and the average age is 70.
