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.

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 benefactorRichard 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).

Houston researchers report promising first in-human trial for implantable cancer therapy

cancer breakthrough

When it comes to cancer remedies, the treatment can be as challenging for the body as its cause. But what if immunotherapy could be localized? That’s precisely what a Houston team may soon make a reality.

Rice University researchers, in partnership with MD Anderson Cancer Center, recently published their findings from the first in-human trial of an implantable cancer-fighting treatment in the journal Clinical Cancer Research. The paper details testing of AVB-001, encapsulated cells engineered to release interleukin-2 (IL-2)—a naturally occurring signaling protein that boosts immunity—in the peritoneal cavities of 14 patients. The goal is to avoid the toxicity usually experienced with less targeted treatments, as well as find a solution to IL-2s’ abbreviated half-lives.

“Traditional IL-2 therapy has shown potent antitumor activity, but its clinical use has been limited by severe side effects and delivery challenges,” Omid Veiseh, director of the Rice Biotech Launch Pad, professor of bioengineering at Rice and a senior author on the study, said in a press release. “This platform allows us to localize and sustain cytokine exposure directly where tumors reside while minimizing systemic toxicity.”

Serous ovarian carcinoma is especially well-suited to the use of AVB-001 because it tends to spread throughout the abdomen. After a minimally invasive laparoscopic procedure, patients implanted with the cells were noted to tolerate the treatment well. Half of the enrolled patients’ cancer was stabilized, with several among them reporting extended signs of benefit. No maximum tolerated dose was reached and there were no life-threatening events tied to the study.

If that sounds like less-than-earth-shaking results, this is only the beginning. The capsules were implanted for about one week because IL-2 activity drops off after that. The researchers now know that further testing should include either higher levels, repeated doses, or a combination thereof, in order to create stronger advances.

The team has already made early headway on this next step. Preclinical studies in nonhuman primates were not only tolerated well, but without added toxicity, the apes had consistent pharmacological effects.

“This is a foundational step,” Veiseh explained. “We now have evidence that the platform is safe, biologically active and potentially scalable. The next phase is optimizing dosing and exploring combination therapies to unlock its full clinical potential.”

The combination would also include a checkpoint inhibitor, which might improve AVB-001’s tumor-fighting power. “What is exciting is that we are not just delivering a drug, we are programming a microenvironment,” added Dr. Amir Jazaeri, professor of gynecologic oncology at MD Anderson, member of the Rice Biotech Launch Pad’s clinical advisory board and a senior author on the study. “This opens the door to combination strategies that could amplify immune responses in ways that have not been feasible before.”
