Houston welcomed a duo of unicorns in 2021, according to a new report. But these unicorns aren’t those mythical multicolored creatures. Rather, they’re startups valued at $1 billion or more.

As of December 2021, there were more than 900 unicorns around the world, according to market research company CB Insights. Former unicorns include Airbnb, Facebook, and Google.

Joining the unicorn club in 2021 were two startups based in the Houston area:

  • Solugen, currently valued at $1.8 billion, according to the company, which uses corn syrup to produce chemicals.
  • Axiom Space, valued at more than $1 billion as of February. The startup is developing the world’s first space station for commercial purposes.

Houston's other unicorn is fintech company, HighRadius, which reached the $1 billion valuation mark in January of 2020.

The Lone Star State added a few other companies to its unicorn herd. Austin had four companies claim the prestigious status — the most newly minted unicorns in Texas — and now has a total of six unicorns. Dallas added one new unicorn to its economy, making a total of three Dallas area-based unicorns, according to CB Insights.

Here are the other 2021 unicorns in Texas:

  • Austin-based Iodine Software, valued at more than $1 billion as of December. The company’s artificial intelligence offering aims to help healthcare organizations improve their operations.
  • Austin-based ZenBusiness, valued at $1.7 billion as of November. ZenBusiness provides an online platform designed to help entrepreneurs start, run, and grow their small businesses.
  • Cedar Park-based Firefly Aerospace, valued at more than $1 billion as of May. The startup makes rockets and commercial spacecraft.
  • Austin-based The Zebra, valued at more than $1 billion as of April. The Zebra runs an online marketplace that enables consumers to compare insurance quotes.
  • Irving-based Caris Life Sciences is valued at a whopping $7.83 billion as of May. Caris employs artificial intelligence to come up with targeted cancer treatments.

Startups, particularly those in the tech space, increasingly are drawn to Austin. In 2020, CompTIA, a trade group for the tech industry, placed Austin atop its Tech Town USA index. The organization cited Austin as a “favorable alternative” to the San Francisco Bay Area and New York City for startups and other companies.

Joshua Baer, founder and CEO of Austin-based Capital Factory, an accelerator for startups, told Texas Monthly in April that Austin’s status as a business magnet has risen recently.

“Suddenly, we’ve gone from us having to beat our chest and tell everybody else how great Austin and Texas are to everybody showing up here, telling us why it’s so great, and why they moved here,” Baer says.

Texas plugs in among states at highest risk for summer power outages in 2025

hot, hot, hot

Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

  • June 2025 — 82,243 megawatts
  • July 2025 — 84,103 megawatts
  • August 2025 — 85,759 megawatts
  • September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

Houston ranks among top 5 cities for corporate HQ relocations in new report

h-town HQ

The Houston area already holds the title as the country’s third biggest metro hub for Fortune 500 headquarters, behind the New York City and Chicago areas. Now, Houston can tout another HQ accolade: It’s in a fourth-place tie with the Phoenix area for the most corporate headquarters relocations from 2018 to 2024.

During that period, the Houston and Phoenix areas each attracted 31 corporate headquarters, according to new research from commercial real estate services company CBRE. CBRE’s list encompasses public announcements from companies across various sizes and industries about relocating their corporate headquarters within the U.S.

Of the markets included in CBRE’s study, Dallas ranked first for corporate relocations (100) from 2018 to 2024. It’s followed by Austin (81), Nashville (35), Houston and Phoenix (31 each), and Denver (23).

According to CBRE, reasons cited by companies for moving their headquarters include:

  • Access to lower taxes
  • Availability of tax incentives
  • Proximity to key markets
  • Ability to support hybrid work

“Corporations now view headquarters locations as strategic assets, allowing for adaptability and faster reaction to market changes,” said CBRE.

Among the high-profile companies that moved their headquarters to the Houston area from 2018 to 2024 are:

  • Chevron
  • ExxonMobil
  • Hewlett-Packard Enterprise
  • Murphy Oil

Many companies that have shifted their headquarters to the Houston area, such as Chevron, are in the energy sector.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, said in 2024. “With deep roots in our region, Chevron is a key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

According to CBRE, California (particularly the San Francisco Bay and Los Angeles areas) lost the most corporate HQs in 2024, with 17 companies announcing relocations—12 of them to Texas. Also last year, Texas gained nearly half of all state-to-state relocations.

In March, Site Selection magazine awarded Texas its 2024 Governor’s Cup, resulting in 13 consecutive wins for the state with the most corporate relocations and expansions.

In a news release promoting the latest Governor’s Cup victory, Gov. Greg Abbott hailed Texas as “the headquarters of headquarters.”

“Texas partners with the businesses that come to our great state to grow,” Abbott said. “When businesses succeed, Texas succeeds.”

CBRE explained that the trend of corporate HQ relocations reflects the desire of companies to seek new environments to support their goals and workforce needs.

“Ultimately, companies are seeking to establish themselves in locations with potential for long-term success and profitability,” CBRE said.

SpaceX test rocket explodes in Texas, but no injuries reported

SpaceX Update

A SpaceX rocket being tested in Texas exploded Wednesday night, sending a dramatic fireball high into the sky.

The company said the Starship “experienced a major anomaly” at about 11 pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX’s launch site at the southern tip of Texas.

“A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,” SpaceX said in a statement on the social platform X.

CEO Elon Musk ’s SpaceX said there were no hazards to nearby communities. It asked people not to try to approach the site.

The company said it is working with local officials to respond to the explosion.

The explosion comes on the heels of an out-of-control Starship test flight in late May, which tumbled out of control. The FAA demanded an investigation into the accident.
