Dallas is rolling in millionaires and a new list offers the proof: A study of the Top 10 Wealthiest Cities in USA by residency and citizenship consultant Henley & Partners puts Dallas at No. 6 — home to 72,400 millionaires as of December 2024.

As if that's not enough, Dallas also has 135 centi-millionaires — meaning they're worth $100 million or more — and 16 billionaires.

According to the study, the number of millionaires in Dallas grew 85 percent from 2014 to 2024.

The study pointed out that Dallas “has seen very strong wealth growth over the past two decades, driven in part by the relocation of several major corporate headquarters to the city. Prominent companies based in the Dallas-Fort Worth area include AT&T, CBRE, Caterpillar, American Airlines, Charles Schwab, and Texas Instruments.”

Houston was the richest city in Texas, coming in at no. 5 and beating Dallas by one place. Austin just squeezed in at 10th place but is rushing to catch up: It had the greatest increase in number of richy-rich in the past decade.

Here’s the rundown for Houston and Austin:

• Houston — 81,800 millionaires, 210 centi-millionaires, and 16 billionaires. Millionaire growth rate from 2014 to 2024: 75 percent.
• Austin — 32,000 millionaires, 90 centi-millionaires, and 10 billionaires. Millionaire growth rate from 2014 to 2024: 90 percent.

In its comments about Houston, the study pointed out that “America’s energy capital, Houston, is a global leader in engineering and aeronautics. It is also home to 24 Fortune 500 companies — the third-highest number among U.S. cities, after New York and Chicago."

Regarding Austin, the study said: “With its booming tech sector, Austin has been dubbed ‘Silicon Hills.’ Several major tech companies have moved their headquarters to the city over the past decade, most notably Tesla. Texas’s low state taxes add to Austin’s appeal. While wealth growth in the city has slowed over the past couple of years, it remains very impressive when viewed over the past decade as a whole.”

New York City topped the overall list, boasting 384,500 millionaires, 818 centi-millionaires and 66 billionaires. But Texas is the only state with three millionaire hubs in the top 10.

On a separate Henley & Partners list, Houston took the No. 5 spot for the most centi-millionaires in the U.S. Dallas ranked seventh and Austin ranked 12th.
