Houston takes flight at Paris Air Show just in time for Space City Month​

Oui, oui

As we move closer to the 50th anniversary of Apollo 11 in mid-July, eyes around the world are turning to the United States and to Houston's NASA Johnson Space Center in celebration of the historic mission that first brought mankind to the moon. Thanks to that unprecedented interest, Houston was asked to be a featured partner of the USA Partnership Pavilion at the Paris Air Show last month.

Drawing nearly 2,500 exhibitors from 49 countries and more than 316,000 total visitors, the Paris Air Show continues to be the world's premier aerospace and aviation industry event. Houston's historic achievements set the stage to showcase how the region continues to be a global hub for technology and innovation.

A delegation of top Houston organizations brought distinct assets that showcased a collective advantage in competing for aerospace business. Led by the Greater Houston Partnership under the promotional banner Space City: The Gateway to Innovation, the group included:

  • Houston Spaceport, one of the nation's 10 licensed commercial spaceports co-located at Ellington Field (EFD).
  • Rice Space Institute, which has helped to establish Rice University's international reputation in all areas of space research by investing in efforts to further the development of new ideas and innovation in the broad area that is space exploration and utilization.
  • SpaceCom, the Space Commerce Conference and Exposition, an annual two-day conference that connects NASA technology with the private sector to fuel future innovation
  • Space Center Houston, the official visitor center of NASA's Johnson Space Center and a leading science and space learning center.
  • Blue Bear Capital, a Houston-based venture capital firm investing in fast-growing private companies that apply data driven technologies and innovative business models to the global energy supply chain.
  • Trumbull Unmanned, A Forbes Top 25 Veteran Founded startup based out of the Houston Spaceport that collects, analyzes, and visualizes critical data for the energy sector, primarily supporting oil and gas and environmental efforts.

As an anchor NASA community and home to the sharpest minds in aerospace, life sciences, energy and innovation, it was only fitting that Houston have a prominent presence in the show at Le Bourget. Among the 300 exhibitors representing the United States in the USA Partnership Pavilion, twenty of which were states, Houston was the only city with a major presence. Throughout the week, the Houston delegation participated in a schedule of high-profile thought-leadership and hospitality events to engage and educate global industry and government decision-makers and influencers.

For our part at the Greater Houston Partnership, we were able to conduct a series of meetings with companies from around the world, gathering more than 40 international and domestic economic development leads. The show is also a great media opportunity that allowed us to secure nearly 20 interviews for our delegation members with print and broadcast outlets from across the U.S. and Europe.

The USA Partnership Pavilion's week-long celebration of innovation and human achievement was led Apollo Astronauts Brig. Gen. Charlie Duke, and Houston-natives Col. Walt Cunningham and Col. Al Warden. Their presence served as a tangible way to connect our nation's achievements to the innovative future of the global aerospace industry.

"The 50th anniversary is such a unique time in history. It gives us an opportunity to think back about what we did, realize where we are today, and where we want to be in the future," says Col. Al Worden, "The most important thing about the space program was not so much about putting a man on the moon, it was about developing the technology to get there. Those technologies have made this country so successful, and I hope we continue to see that type of commitment to technology development in the future."

Houston delegates were asked to participate in several thought leadership panels.

"As we continue to explore further into the universe, there are a myriad of technical challenges that need to be overcome," says David Alexander, director of Rice Space Institute, who moderated a panel discussion on advancing technologies that will help humans physically and mentally adapt to deep space exploration. He was joined by industry leaders from United Launch Alliance (ULA), Lockheed Martin, Virgin Galactic, and Harris Corporation for the conversation centered around the use of artificial intelligence, 3D printing and additive manufacturing.

Governments around the globe including those in Europe, China and of course the United States have accelerated a discussion about sending humans back to the moon as a key step in our continued human exploration of deep space. This concept is also proving attractive to private companies, with an increase in public-private partnerships and a broader role being played by commercial entities in government aspirations.

Former astronaut and Space Station Commander turned venture capital leader Tim Kopra participated in a panel discussion on this very topic alongside representative from United Launch Alliance (ULA), the Federal Aviation Administration (FAA), Lockheed Martin, Deloitte, and the U.S. Air Force. Although Kopra's Blue Bear Capital's primary target are data-driven technologies in the energy industry, he notes that "there are a lot of intersections between energy and aerospace, and Houston's melting pot of global industries has turned the region into a hot bed for innovation with broader application of technologies."

The centerpiece of the Houston delegation's presence at the Paris Air Show was an executive briefing on June 19 featuring keynote remarks from Kopra that helped set the tone for the work Houston continues to do in innovation and aerospace technology. Kopra discussed his background with NASA, the transition into the funding scene that supports the region's growing innovation ecosystem, and what Houston has to offer businesses looking to expand their operations in the areas of aerospace, manufacturing, and digital technology.

A panel discussion followed, addressing topics that included educating the next generation of engineers and explorers, the intersection of NASA technology and the private sector, the next frontier of space exploration and the unique position that Houston has in pioneering those efforts.

"Over the past 58 years, Johnson Space Center has led the U.S. and the world in human exploration, discovery, and achievement in space," Kopra tells the audience. "Now we are in a position of transitioning a lot of those capabilities into the civilian sector."

The Houston Spaceport is one big step in that ongoing evolution. As the only commercial spaceport in the nation centered in a large metropolitan area, the Houston facility will have unmatched access to resources for companies and operators, said Arturo Machuca, general manager of the spaceport.

"The Houston Spaceport is being developed to ensure Houston stays relevant in commercial aerospace and aviation activities," he says. "Houston continues to hold a strong value proposition for companies looking to enter the aerospace industry with a unique set of advantages including the proximity to NASA's Johnson Space Center, unparalleled infrastructure through the Houston Airport System, and a strong talent base."

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.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
