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

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.

Texas billionaire and family reign as the world’s richest clan

RETAIL RICHES

It's hardly a surprise that America's Walton family, including Fort Worth billionaire Alice Walton, remains the world's richest family. What's truly stunning is how much their wealth has grown in the past year — by more than $23 billion.

In once again crowning the Waltons the world's richest family, the Bloomberg news service recently reported that their collective fortune had risen by $23 billion in the past year due to the climbing stock price of the Walmart retail chain. Sam Walton opened the first Walmart store in 1962.

Descendants of Sam and his brother, Bud, control more than 1.3 billion shares of Walmart stock either directly or through family trusts, Bloomberg says. Even though the Waltons have liquidated $6 billion in Walmart stock this year, they're now worth more in 2021 than they were in 2020.

As of mid-September, the Waltons were worth $238.2 billion, according to Bloomberg. That's almost $100 billion above the next richest family in the world, the Mars family of candy and pet care fame. Last year, Bloomberg pegged the Waltons' fortune at $215 billion.

To put the Waltons' one-year, $23 billion bump in wealth into perspective, Bloomberg estimates the net worth of Walmart heir Lukas Walton at $22 billion.

Alice Walton ranks as the second richest person in Texas (No. 1 is Elon Musk, at more than $200 billion), but she's not the richest Walmart heir. As of September 27, Bloomberg estimated Walton's net worth at $61.9 billion, making her the 19th richest person in the world. Ahead of her are brothers Jim ($63.7 billion, No. 17 worldwide) and Rob ($63.3 billion, No. 18 worldwide).

Not everyone is impressed with the Waltons' mountain of money. In February, U.S. Sen. Bernie Sanders, an independent from Vermont, branded the Waltons "the poster child for greed," based on the retailer's low starting wage. Walmart recently raised its minimum pay for hourly workers from $11 to $12.

"This is a family that is incredibly wealthy," Sanders said of the Waltons before the wage increase took effect.

"One of their owners spend[s] zillions of dollars on antique cars. They've got mansions. They have all kinds of art collections," the senator told CNN. "But somehow or another they can't pay their starting wage at more than 11 bucks an hour."

UTHealth Houston officially opens new tower in TMC's Helix Park

open for innovation

UTHealth Houston School of Public Health recently opened its new state-of-the-art tower in the Texas Medical Center’s Helix Park.

The 350,000-square-foot, 10-story campus at 1930 Old Spanish Trail was celebrated with an official ribbon-cutting ceremony on Oct. 28. The $229 million project will consolidate all UTHealth Houston School of Public Health operations into one facility. It will also connect students who are at the Austin, Brownsville, Dallas, El Paso and San Antonio campuses with peers and faculty through digital and distance learning.

Disciplines taught in the new tower will include epidemiology, genetics, nutrition, health policy, data science and health promotion, UTHealth shared when the building first broke ground in 2023.

Architects Kirksey Architecture and Smith Group designed the building, and Vaughn Construction served as general contractor. The facility features labs for studying human disease, classrooms and spaces to support interdisciplinary and community-based research, a broadcast studio and a teaching kitchen. A skybridge over Old Spanish Trail connects the new tower with a plaza that's shared with MD Anderson.

“This new facility reflects the kind of forward-looking investment that will serve Texans for generations,” Janiece Longoria, vice chairman of the UT System Board of Regents, said in a news release. “By creating an environment where talented people can learn, collaborate, and pursue new ideas, UTHealth Houston is building capacity to meet the challenges of tomorrow while strengthening its impact across our state.”

UTHealth says the system aims for the new campus to expand on collaborative research efforts and continue graduate education, as enrollment at the School of Public Health has increased by 27 percent over the last five years.

“This new building, with its state-of-the-art education technology and learning environment, will strengthen and advance the school’s mission to educate and train the next generation of experts who will advance scientific discovery, shape evidence-based health policy, and lead innovative solutions to the complex health challenges in communities throughout Texas and across the nation,” Kevin Morano, senior vice president, provost and chief academic officer of UTHealth Houston, added in a news release.

Attending the ceremony were Dr. Melina R. Kibbe, UTHealth Houston president and Alkek Williams Distinguished Chair; Eric Boerwinkle, dean, M. David Low Chair in Public Health and Kozmetsky Family Chair in Human Genetics at the School of Public Health; Texas State Representative Lauren Ashley Simmons, Texas House District 146; representatives of the offices of Senator John Cornyn and Harris County Commissioner Rodney Ellis; and Dr. Theresa Tran, director of the Houston Health Department.

"This building represents far more than a home for our school,” Boerwinkle added in the release. “It represents the people who make our mission possible: the faculty, staff, and students who fill each laboratory and classroom with curiosity, discovery, and purpose to improve the population’s quality of life.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.
