According to Forbes, half of all of the world’s billionaires are less wealthy than they were in 2022. But that’s not the case for most Houston-area billionaires like oil tycoon Jeffery Hildebrand, who was named the richest man in the city.

The 2023 edition of Forbes’ World’s Billionaires List declared Hildebrand’s net worth at $10.2 billion, placing him as the 171st richest person in the world. His fortune is $2.7 billion higher than his 2022 net worth of $7.5 billion, when he ranked No. 316 on the list.

As CultureMap reported, in 2015, Hildebrand made headlines when he gifted each of his 1,381 employees a $100,000 holiday bonus.

Houston’s favorite hospitality mogul and Rockets owner Tilman Fertitta is the city’s second-richest man, with his net worth climbing up to $8.1 billion. He ranked No. 256 on Forbes’ list, substantially higher than his No. 471 rank in 2022 when his net worth was $5.6 billion. Fertitta is surely living life to the fullest after hosting Miami rapper Pitbull at his San Luis Salute celebration earlier this year.

Other Houston-area billionaires that made Forbes 2023 world’s richest list are:

  • Pipeline magnate Richard Kinder: tied for No. 317, $7.2 billion, down from $7.5 billion
  • Houston siblings and pipeline heirs Dannine Avara, Scott Duncan, Milane Frantz, and Randa Duncan Williams: all tied for No. 352, $6.8 billion, up from $6.6 billion

New to the 2023 report is Kamal Ghaffarian, the co-founder and executive chairman of Houston's Axiom Space, with a net worth of $2.1 billion. Though his LinkedIn notes that he is based in Maryland, reports add that he resides in Florida. His Forbes rank is No. 1434.An honorable mention (and billionaire newbie) is Amy Adams Strunk, the controlling owner of the Tennessee Titans and daughter of Houston Oilers owner Bud Adams. She has a residence in Waller (about 40 miles northwest of Houston) and her net worth is $1.7 billion — making her No. 1725 on the list.One name missing from Forbes 2023 report is software entrepreneur Robert Brockman, who passed away last August. Brockman fell from grace after he was charged in the largest tax fraud case in U.S. history in 2020. Forbes listed his 2022 net worth at $4.7 billion. He is survived by his wife, son, and two grandchildren.Elsewhere in Texas, Elon Musk reigns as the richest man in the state and in its capital city of Austin with a net worth of $180 billion. The Tesla and Space-X founder is the second richest person in the world, wedging his way between No. 1 Bernard Arnault of France (overseer of the LVMH empire of 75 fashion and cosmetics brands, including Louis Vuitton and Sephora), with a net worth of $211 billion; and No. 3 Jeff Bezos, the American Amazon founder, worth $114 billion.

Dallas Cowboys owner Jerry Jones'$13.3 billion net worth won him the title of Dallas' richest person, and the 12th richest sports owner on Forbes' "World's Richest Sports Owners 2023." His net worth is up from $10.6 billion last year.

The Fort Worth-based Walmart family heiress Alice Walton earned a spot on Forbes’ list as the third richest woman in the world. Her fortune is pegged at $56.7 billion, down slightly from $65.3 billion last year.

Richard Kinder and 10 other Houston billionaires cash in on Forbes list of richest Americans

where's the money

Never one to overtly draw attention to himself, Houston pipeline magnate — and Memorial Park benefactor — Richard Kinder has landed on a coveted list, as have 10 other Houstonians.

Forbes has released the Forbes 400 list of richest Americans, and Kinder ranks eighth in Texas and 128th nationally with an estimated net worth of $7.1 billion.

Meanwhile, Houston hospitality king and Rockets owner Tilman Fertitta ranks 11th in Texas and 158th nationally with an estimated net worth of $6.3 billion.

Houston pipeline heirs Dannine Avara, Scott Duncan, Milane Frantz, and Randa Duncan Williams tie for 12th place in Texas and tie for 161st nationally. Each has an estimated net worth of $6.2 billion.

Software entrepreneur Robert Brockman ranks 19th in Texas and ties for 229th nationally with a net worth of $4.7 billion.

Oil mogul Jeffery Hildebrand ranks 20th in Texas and ties for 240th nationally with a net worth of $4.6 billion.

Toyota mega-dealer Dan Friedkin ranks 24th in Texas and ties for 253rd with an estimated net worth of $4.4 billion.

Houston Texans owner Janice McNair of Houston ranks 26th in Texas and ties for 269th nationally with an estimated net worth of $4.2 billion.

Finally, local hedge fund honcho John Arnold ties for 30th in Texas and ties for 358th nationally with an estimated net worth of $3.3 billion.

Here's how billionaires from other major metros in Texas fared on the Forbes 400 list.

Austin

No shocker here: Tesla and SpaceX guru Elon Musk ranks No. 2 among the richest Americans and No. 1 among the richest Texans. What is shocking, however, is how much Musk's net worth skyrocketed from 2020 to 2021. Hint: It's more than $100 billion.

This year, the Forbes 400 estimates his net worth stood at $190.5 billion as of September 3. To give that some context, the size of the economy in the state of Kansas exceeds $193 billion.

Last year, Musk's estimated net worth was $68 billion. This means that from 2020 to 2021, his net worth exploded by $122.5 billion, or 180 percent.

Among the richest Americans, only Amazon's Jeff Bezos beats Musk — but not by much. The Forbes 400 pegs Bezos' net worth at $201 billion as of September 3, up from $179 billion at the same time last year.

Forbes lists Musk's residence as Austin, although he has said he spends much of his time in Boca Chica. The Texas Gulf Coast community hosts Starbase, a launch site for SpaceX rockets. Regardless of precisely where he lives, Musk does spend a lot of time in the Austin area, where Tesla is building a $1.1 billion vehicle manufacturing plant. Musk relocated to Texas last year.

Before Musk arrived in the Lone Star State, Walmart heir Alice Walton of Fort Worth ranked as the richest person in Texas. She's now in second place, with a net worth estimated at $67.9 billion. Walton ranks as the 12th richest American and richest American woman on this year's Forbes 400.

Aside from Musk, Austin billionaires who appear on the Forbes 400 are:

  • Michael Dell, founder, chairman, and CEO of Round Rock-based Dell Technologies. Estimated net worth: $50.1 billion. Texas rank: No. 3. U.S. rank: No. 18.
  • Robert Smith, founder, chairman, and CEO of private equity firm Vista Equity Partners. Estimated net worth: $6.7 billion. Texas rank: No. 9. U.S. rank: No. 141.
  • Vodka titan Bert "Tito" Beveridge. Estimated net worth: $4.8 billion. Texas rank: No. 18. U.S. rank: No. 224 (tie).
  • IT entrepreneur Thai Lee. Estimated net worth: $4.1 billion. Texas rank: No. 27 (tie). U.S. rank: No. 273 (tie).
  • Software entrepreneur Joe Liemandt. Estimated net worth: $3 billion. Texas rank: No. 33 (tie). U.S. rank: No. 377 (tie).
  • Jim Bryer, founder and CEO of venture capital firm Bryer Capital. Estimated net worth: $2.9 billion. Texas rank: 35 (tie). U.S. rank: No. 389 (tie).

Air taxis network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” She added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

5 Houston deep tech startups pushing the boundaries of their industries

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Casimir

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.
