As if Houston needed any more evidence that the city is booming, a new report reveals that the Bayou City boasts the most billionaires in Texas.

Thirteen Houston billionaires land on the latest Forbes 400 list of the richest Americans. Ranked in order, the Houstonians are Richard Kinder (No. 79), Dannine Avara (No. 88), Scott Duncan (tied for No. 88), Milane Frantz (tied for No. 88), Randa Williams (tied for No. 88), Tilman Fertitta (No. 153), Dan Friedkin (No. 179), Jeffery Hildebrand (tied for No. 179), Robert McNair (No. 200), John Arnold (No. 239), George Bishop (No. 328), Drayton McLane Jr. (No. 354), and Leslie Alexander (No. 383).

The Houston list features familiar sports franchise owners (Fertitta, McNair, McLane, and Alexander); the youngest Texas billionaire (Duncan, at 35); and one of only two Texans to earn a top Forbes philanthropy score (Arnold, for his impressive post-Harvey charity). Kinder has also recently gained even more fame in Houston thanks to his massive gift to Memorial Park.

Many try, but no one, it seems, can topple Walmart heiress Alice Walton of Fort Worth from her perch as the wealthiest person in Texas. In fact, her net worth soared by $6.7 billion from 2017 to 2018, according to the latest Forbes 400 list of the richest Americans.

The new Forbes 400 ranking puts Walton, with an estimated net worth of $44.9 billion, atop the list of Texas billionaires and at No. 12 nationwide.

Walton also happens to be the country’s and world’s richest woman. Last year, Walton ranked 13th nationwide with an estimated net worth of $38.2 billion, up from $35 billion in 2016 and $32 billion in 2016. From 2017 to 2018 alone, Walton’s net worth jumped nearly 18 percent.

Not far behind her on this year’s Forbes 400 — at No. 2 in Texas and No. 17 in the U.S. — is Austin tech titan Michael Dell, whose net worth is estimated at $27.6 billion in 2018, up from $23.2 billion last year. He’s chairman and CEO of the Round Rock-based tech company that bears his name.

For those keeping score, Houston leads the Texas list (13), followed by Dallas (12), Fort Worth and Austin (six each), and Brownsville (one). No one from San Antonio appears in this year’s Forbes 400.

Walton and Dell are the only two Texans among the 20 richest Americans. In all, 38 Texans appear in this year’s Forbes 400. Other than Walton and Dell, they are:
