Houston VC funding nears $1B in first half of 2026, report says

by the numbers

Despite a weak second quarter, venture capital funding for Houston-area startups approached $1 billion in the first half of 2026, the region’s highest first-half total since 2022, according to the latest PitchBook-NVCA Venture Monitor.

This year’s first-half total of $962.4 million represented a nearly 8 percent increase over last year’s first-half total of $891.7 million. Dating back to 2016, this year’s first-half haul lags behind only 2021 and 2022 for the most first-half funding.

Houston’s year-over-year VC jump of 73 percent in the first quarter of 2026 more than made up for the year-over-year drop of 34 percent in the second quarter of 2026, according to the report.

Deal count tells a more encouraging story: Houston startups closed 102 deals in the first half, up from 93 a year earlier and the region’s busiest first half since 2022. However, the average deal size shrank, as no single funding source dominated the total.

Keep in mind that PitchBook and NVCA routinely revise quarterly numbers upward to reflect deals that were reported after a previous quarter’s data was published. So, in the case of Houston, numbers initially reported for the first quarter of 2026 may not match newly reported numbers.

Perhaps the most notable Houston-area deal announced in the first half of this year was Cart.com’s $180 million growth equity investment, led by Springcoast Partners. Cart.com is an e-commerce platform and logistics provider.

PitchBook-NVCA data shows Houston’s VC activity is growing modestly, delivering better numbers in the first half of 2026 versus 2024 and 2025, but it still sits below the highs of 2021 and 2022. This is one sign that so far in 2026, the national VC boom isn’t benefiting non-hub markets like Houston the way it’s boosting some hub markets, especially Silicon Valley and New York City.

Nationwide, AI dominated VC funding in the first half of this year. The sector made up 86 percent of VC from January through June. The report notes that the markets have still struggled to unlock IPOs, with SpaceX being the biggest exception, and few M&A deals outside health care have been significant.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

Houston-based Solugen, a startup that specializes in combating carbon dioxide emitted during the production of chemicals, has hauled in $357 million in a Series C funding round. That amount eclipses the size of any Houston VC funding round this year or last year.

Singapore-based GIC and Edinburgh, Scotland-based Baillie Gifford led the round, with participation from Temasek Holdings, affiliates of BlackRock, Carbon Direct Capital Management, Refactor Capital, and Fifty Years.

Since its founding in 2016, Solugen has raised more than $405 million in venture capital, according to Crunchbase.

"Solugen's vision for cleaner chemicals through synthetic biology has the potential to be a fundamental shift in how chemicals are made, to help tackle the environmental challenges we face globally. The chemical market itself is colossal, and Solugen is just getting started," Kirsty Gibson, investment manager at Baillie Gifford, says. Click here to continue reading.

A Houston-based software company providing clinicians a turn-key platform for their practice has announced the close of its seed funding round.

DocSpace raised $1.2 million in seed funding led by Slauson & Co. with participation by Precursor Ventures, Acrew Capital's Scout Fund, and SputnikATX Ventures.

"Existing practice management software requires clinicians to manually self-navigate the expensive and complicated business formation process before they're able to utilize any of their product services," says Amaro in a news release. "When you require clinicians to do all the hard work of starting a new business then force them to purchase expensive software, it's no surprise that fewer clinicians have the opportunity to build new businesses in their communities."

Houston space companies take off with new tech, deals and contracts

space update

Space City has had a busy month.

Houston-based aerospace institutions Venus Aerospace, Axiom Space, and Aegis Aerospace have each recently announced advancements in their respective fields that include expansions and new contracts from U.S. and international government agencies.

Here’s the latest:

Venus launches new test stand

Earlier this month, Venus Aerospace added infrastructure to support the ongoing progress of its Rotating Detonation Rocket Engine (RDRE) with the opening of its new propulsion test stand at the Houston Spaceport.

The Texas Space Commission's Space Exploration and Aeronautics Research Fund is funding the test stand, which is part of a larger effort from the state to increase investments in the aerospace economy. The ribbon-cutting event on Sept. 10 welcomed officials from Venus Aerospace, the Texas Space Commission, the Houston Spaceport, Houston business and local community leaders.

With the new stand, Venus will be able to test at higher thrust and for longer durations, which will allow the company to better replicate real-life conditions.

"Building and testing propulsion systems at this pace requires the right infrastructure around the technology," Sassie Duggleby, CEO and co-founder of Venus Aerospace, said in a news release. "We're grateful to the Texas Space Commission and the State of Texas for investing alongside companies like Venus. Public investment like this helps companies move faster and keeps critical aerospace capability growing here in Texas."

Venus closed a $91 million Series B in July and expanded its leadership team.

Axiom partners in Europe

Axiom Space has signed a memorandum of understanding with the European Space Agency for “sustained European access to low-Earth orbit (LEO)” following the retirement of the International Space Station, according to a news release from the company.

Under the agreement, Axiom and the ESA agreed to explore future astronaut missions on the ISS and Axiom Station, research, transportation and spacesuit partnerships. The organizations will explore using the ESA’s European Cargo Return service and potentially a future European crew vehicle to support operations at Axiom Station, the company's forthcoming commercial space station. The partnership could also involve Axiom's AxEMU spacesuit for orbital and lunar applications, according to the release.

“With the upcoming de-orbitation of the ISS, it is our duty to anticipate and prepare future solutions to ensure our access to low-Earth orbit,” Daniel Neuenschwander, director of human and robotic exploration at ESA, said in the release. “The two documents signed today underline both our commitment to safeguard our ability to pursue in-orbit science and to keep offering flight opportunities to our European astronaut corps, as well as the growing interest of international partners for our ongoing project to develop an autonomous European cargo vehicle.”

The announcement comes as Axiom has made several international moves this year. The company shared plans to establish Axiom Space Switzerland this summer and launched Axiom Space Japan in July.

"The path to a sustainable human presence in space runs through international collaboration — reliable supply chains, shared innovation, and partners who bring real capability," Jonathan Cirtain, CEO and President of Axiom Space, said in the release. "Europe's contributions to microgravity science and deep space technology make ESA exactly that kind of partner. This MoU strengthens our work together, and we look forward to ESA and its member states joining us as customers for future astronaut missions."

Aegis expands DoW deal

Webster, Texas-based Aegis Aerospace announced that it has won a new task order to continue supporting the U.S. Space Force’s Space Test Program.

The contract starts in October and covers designing, building, testing and operating Department of War payloads or equipment on NASA, government, and commercial launch vehicles and platforms. The contract was issued by the USSF Space Systems Command, Space Test Program under NASA Johnson Space Center’s Research, Engineering, and Mission Integration Services 2 (REMIS 2).

Currently, the company is working on three payload facilities on the ISS and has plans for two more in development.

“Aegis Aerospace is grateful to continue our exceptional payload integration support to the USSF and the STP to meet their critical mission objectives,” President Matt Ondler added in the release. “This work is more important than ever to maintain U.S. superiority in space. This new contract will take us beyond the current life of the ISS and see us integrate and test payloads on commercial space stations, free-flyers, and cislunar missions.”

10 Houston billionaires land on Forbes' 2026 list of richest Americans

America's Richest

The richest billionaires in America have a collective worth of $8 trillion in 2026, a staggering $1.4 trillion increase since last year, says Forbes. American billionaires are so wealthy that it now takes an unprecedented $4.4 billion net worth to be considered one of the richest people in the country. And one local billionaire has regained the title as Houston's wealthiest resident.

Oil tycoon Jeffery Hildebrand, 67, now reigns as the No. 1 richest Houstonian, the 9th richest Texan, and the 88th richest person in America for 2026.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies. In all, 43 billionaires across Texas made it on the 2026 list, and 10 are based in Houston.

Hildebrand's net worth has surged $4.7 billion since last year, bringing his current net worth to $14.7 billion. He cofounded Hilcorp, one of the largest privately owned oil and natural gas producers in the U.S., in 1990 and served as its CEO until 2018. He still serves as the chairman of the company.

Hildebrand skyrocketed past several other Houston billionaires to claim the top spot citywide: Kinder Morgan chairman Richard Kinder, Toyota mega-dealer Dan Friedkin, and hospitality honcho Tilman Fertitta.

Kinder, 81, was dubbed Houston's richest billionaire in the 2025 Forbes 400 list, whose net worth has increased from $11.1 billion to $12.9 billion in just one year. He is the 11th richest Texan and the 100th richest person in America.

Friedkin, 61, is the third-richest Houstonian and the 102nd richest American with an estimated net worth of $12.9 billion, up from $9.7 billion last year. He most notably owns Gulf States Toyota, which sold $14.5 billion worth of Toyotas in 2025, per Forbes.

The Friedkin family is also in talks to launch a new NHL team in Texas, with Houston and Austin being eyed as potential home bases, CultureMap reports. Bringing a professional hockey team to Houston would be a major boon for the city, which has been without one since the Houston Aeros folded in 2013.

Fertitta, 69, has a net worth of $12.3 billion and is the fourth richest Houstonian and the 110th richest American. Fertitta owns hospitality corporation Fertitta Entertainment and the NBA team Houston Rockets. He most recently purchased the WNBA's Connecticut Sun and plans to relocate them to Houston under the Houston Comets name in 2027. He also keeps himself busy as President Trump's ambassador to Italy.

There's also one new Houston-based billionaire making his debut on the Forbes 400: Houston Texans owner and CEO Cal McNair.

McNair, 64, took over as the principal owner of the NFL team after his late mother, Janice McNair, transferred her principal stake to him in 2024. Janice, who cofounded the Texans with her late husband Bob McNair, passed away in July 2026. She previously had an estimated net worth of $7.3 billion.

Cal McNair ranks as the 218th richest person in America with an estimated net worth of $7.7 billion.

Here's how the rest of Houston's billionaires fared on this year's list:

  • Houston pipeline heir Randa Duncan Williams ranks 124th with an estimated net worth of $11.7 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 128th nationally. Each has an estimated net worth of $11.6 billion. Scott Duncan ties for No. 137 with an $11.3 billion estimated net worth.
  • Energy exploration chief exec George Bishop of The Woodlands ranks No. 380 with an estimated net worth of $4.5 billion. Last year: $4.7 billion.

Texas' richest billionaires
Walmart heiress Alice Walton, 76, who currently leads as the richest woman globally, is also the richest woman in America, the third-wealthiest person in Texas, and the richest Fort Worth resident for 2026.

Walton's net worth has grown by $12 billion since last year, bringing her current net worth to $118 billion. She is the only daughter of late Walmart cofounder Sam Walton, though she focuses her attention on other endeavors like the Crystal Bridges Museum of American Art and the Alice L. Walton School of Medicine in Bentonville, Arkansas. Forbes still lists her residence as Fort Worth. Walton is one of only 62 women billionaires on the Forbes 400 list, making up just 16 percent of the total list.

3 Houston children's hospitals ranked best in the nation by U.S. News

Hospital Honor Roll

Houston has many renowned hospitals providing exceptional care, and now three local medical centers have earned national acclaim for their top-notch healthcare for children and adolescents.

Texas Children's Hospital, Children's Memorial Hermann Hospital, and Children's Cancer Hospital-MD Anderson Cancer Center are the three local pediatric care centers named in U.S. News and World Report's 2026-2027 Best Children's Hospitals.

Each year, U.S. News surveys over 100 children's hospitals and thousands of pediatric specialists to determine it's Best Children's Hospitals rankings. The winning hospitals excel at various factors such as "clinical outcomes, compliance with established best practices, and level and quality of hospital resources directly related to patient care."

Out of the 90 total children's hospitals selected across 34 states and Washington, D.C., only six were based in Texas.

"For two decades, U.S. News has helped guide families to top-tier pediatric care," said Ben Harder, chief of health analysis and managing editor at U.S. News, in a release. “Finding the right medical team for a rare diagnosis or complex surgery can be overwhelming, and U.S. News’ annual evaluation of the Best Children’s Hospitals provides a clear starting point for parents and referring pediatricians alike."

Texas Children's Hospital reigns as the No. 1 pediatric hospital in the Lone Star State and in the Southwest, and it was the only Texas hospital to be named in U.S. News' national Best Children's Hospitals Honor Roll list for 2026-2027.

Texas Children's also leads as the No. 1 best hospital in the U.S. in two pediatric specialties — Cardiology and Heart Surgery; Diabetes and Endocrinology. It earned top-five acclaim in seven more nationally ranked specialties: Nephrology (No. 2); Pulmonology and Lung Surgery (No. 2); Urology (No. 2); Neurology and Neurosurgery (No. 3); Gastroenterology and GI Surgery (No. 5); Neonatology (No. 5); and Orthopedics (No. 5).

The hospital also ranked as the country's 12th best pediatric cancer hospital, and it's one of the top 50 Best Children's Hospitals for Behavioral Health in the U.S.

Children's Memorial Hermann Hospital is the No. 3 best pediatric hospital in Texas for 2026-2027, and it earned top-50 ranks in seven specialties:

  • No. 12 – Cardiology and Heart Surgery
  • No. 26 – Neonatology

  • No. 34 – Neurology and Neurosurgery
  • No. 40 – Orthopedics
  • No. 50 – Nephrology
  • "Top 50" Best Children's Hospitals for Behavioral Health

MD Anderson's Children's Cancer Hospital was unranked in the statewide list of the best pediatric care centers. It ranked as the No. 33 best pediatric cancer hospital in the U.S.

Other high-performing Texas pediatric hospital include Children's Health Dallas, Dell Children's Medical Center in Austin, and Cook Children's Medical Center in Fort Worth.
