Texas is home to second largest population of millionaires in the U.S.

The Millionaires Club

Tilman Fertitta, Elon Musk, Alice Walton, and Jerry Jones are members of the billionaires club in Texas. But just how many millionaires does the Lone Star State boast?

Altogether, 73,930 Texans were classified as millionaire tax filers in 2022, according to an analysis of IRS data by digital marketing firm Hennessey Digital. (For context, that millionaire count is just a few thousand shy of the entire population of Missouri City.) This figure puts Texas in the No. 2 spot for the country’s biggest population of millionaire taxpayers, behind first-place California.

However, if you crunch the figures a different way, Texas’ millionaire status isn’t quite as impressive, demonstrating that not everything is bigger in Texas. Texas ranks 10th among the states with the highest proportions of millionaire taxpayers, the study indicates. According to Hennessey Digital’s calculations, 27.1 of every 10,000 Texas tax filers reported adjusted gross income of at least $1 million for the 2022 tax year.

“The state’s booming economy, driven by energy, technology, and business-friendly policies, contributes to its wealthy population,” says Hennessey Digital.

Forbes ranked 43 Texans among the 400 wealthiest Americans last year, with Elon Musk topping the list. Houston hospitality king, Rockets owner, and newly appointed ambassador to Italy Tilman Fertitta was the 12th richest Texan and the 99th richest person in the United States, according to Forbes.

Which state comes out on top for the largest share of millionaire taxpayers? Connecticut, with 44.76 millionaire tax filers for every 10,000 filers, the Hennessey study shows. A number of well-to-do Connecticut suburbs are situated just a commuter train ride away from New York City, where bankers, brokers, and others pull in the big bucks. (Connecticut sits two spots above New York state in the millionaire ranking.)

The numbers in the study “highlight the diverse economic landscapes across our nation. States with favorable tax policies and thriving industries tend to attract more high-income earners,” says Jason Hennessey, CEO of Hennessey Digital. “Understanding these patterns can provide valuable insights for businesses and individuals making decisions about where to live, work, or invest.”

Local billionaires Jeffery Hildebrand and Tilman Fertitta top list of richest in Houston, per Forbes

meet the billionaires

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
  • Toyota mega-dealer Dan Friedkin: tied for No. 466, $5.5 billion, up from $4.3 billion
  • Houston Texans owner Janice McNair: tied for No. 534, $5 billion, up from $4.2 billion
  • Hedge fund honcho John Arnold: tied for No. 878, $3.3 billion, unchanged since 2018
  • Energy exploration chief exec George Bishop: tied for No. 982, $3 billion, up from $2.7 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.

Coya Therapeutics

Clinical-stage biotechnology company Coya Therapeutics (NASDAQ: COYA) has developed COYA-302 that enhances anti-inflammatory T cell function and suppresses harmful immune activity. The drug candidate is being advanced for several neurodegenerative diseases—including ALS, Alzheimer’s, Parkinson’s, and frontotemporal dementia—and has demonstrated promising reductions in neuroinflammation in preclinical and early clinical studies, according to the company.

Coya, founded in 2021, received FDA acceptance for its investigational new drug application for COYA-30 this summer. It closed its IPO in January 2023 for more than $15 million and added $26 million in PIPE funding that same year. Last year, the company secured an additional $15 million in PIPE funding.

Fervo Energy

Houston-based Fervo Energy is working to provide 24/7 carbon-free energy through the development of cost-competitive geothermal power. The company is developing its flagship Cape Station geothermal power project in Utah, which is expected to generate 400 megawatts of clean energy for the grid. The first phase of the project will supply 100 megawatts of power beginning in 2026. The second phase is scheduled to come online by 2028.

The company raised $205.6 million in capital to help finance the project earlier this year and fully contracted the project's capacity with the addition of a major power purchase agreement from Shell. Founded in 2017 by CEO Tim Latimer and CTO Jack Norbeck, Fervo is now a unicorn, meaning its valuation as a private company has surpassed $1 billion. In March, Axios reported Fervo is targeting a $2 billion to $4 billion valuation in an IPO.

Koda Health

Houston-based Koda Health has developed an advance care planning platform (ACP) that allows users to document and share their care preferences, goals and advance directives for health systems. The web-based platform guides patients through values-based decisions with interactive tools and generates state-specific, legally compliant documents that integrate seamlessly with electronic health record systems. The company also added kidney action planning to its suite of services for patients with serious illnesses last year.

Koda Health was founded out of the TMC's Biodesign Fellowship in 2020 by CEO Tatiana Fofanova, chief medical officer Dr. Desh Mohan, and chief technology officer Katelin Cherry. The company raised a $7 million series A earlier this year, and also announced major partnerships and integrations with Epic, Guidehealth, Medical Home Network, Privia Health and others.

Mati Carbon

Houston climatetech company Mati Carbon removes carbon through its Enhanced Rock Weathering (ERW) program that works with agricultural farms in Africa and India. Mati says the farmers it partners with are some of the most vulnerable to the impacts of climate change. The nonprofit won the $50 million grand prize in the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation, earlier this year.

Mati Carbon scaled operations in India, Zambia, and Tanzania this year and has advanced its proprietary measurement, reporting and verification (MRV) platform, known as matiC, enabling seamless field data capture, chain-of-custody and carbon accounting at scale. The company was founded in 2022 by co-directors Shantanu Agarwal and Rwitwika Bhattacharya.

Molecule

Houston-based Molecule Software has developed an energy trading risk management (ETRM) platform that allows companies trading power, oil and gas, biofuels, renewables and more stay ahead as the markets evolve.

The company closed a Series B round earlier this year for an undisclosed amount. Sameer Soleja, founder and CEO of Molecule, said at the time that the funding would allow the company to "double down on product innovation, grow our team, and reach even more markets." The company was founded in 2012 by CEO Sameer Soleja and participated in the Surge Accelerator the same year.

Utility Global

Houston-based Utility Global has developed its proprietary eXERO technology that produces low-cost, clean hydrogen from water and industrial off-gases without requiring grid electricity.

First founded in 2018 by CEO Parker Meeks, the company participated in Greentown Labs and the Rice Alliance for Technology and Entrepreneurship programs. It raised a $55 million funding round earlier this year and launched commercial partnerships with ArcelorMittal Brazil and Hanwha Group in South Korea to deploy its hydrogen solutions at scale.

Venus Aerospace picks up investment from Lockheed Martin Ventures

space funding

Venus Aerospace, a Houston-based startup specializing in next-generation rocket engine propulsion, has received funding from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, for an undisclosed amount. The product lineup at Lockheed Martin includes rockets.

The investment follows Venus’ successful high-thrust test flight of its rotating detonation rocket engine (RDRE) in May. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

Venus says the Lockheed Martin Ventures investment reflects the potential of Venus’ dual-use technology for defense and commercial uses.

“Venus has proven in flight the most efficient rocket engine technology in history,” Venus co-founder and CEO Sassie Duggleby, a board member of the Texas Space Commission, said in a news release. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

Chris Moran, executive director and general manager of Lockheed Martin Ventures, said Lockheed Martin has been a longtime supporter of early-stage “transformational” technologies.

“Our investment in Venus Aerospace reflects a conviction that next-generation propulsion will define which nations lead in space and defense for decades to come,” Moran added in the release. “We are committed to helping Venus scale this technology and integrate it into critical systems.”

Since its founding in 2020, Venus has secured more than $106 million in funding. In addition to Lockheed Martin Ventures, investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. Supporters of Venus include NASA, the Air Force Research Lab and the Defense Advanced Research Projects Agency (DARPA).
