A Houston software company is cashing in on the growing esports industry with a multimillion-dollar fundraising round led by a local investor.

Mainline, which specializes in esports tournament software and management, closed its series A at $6.8 million. Houston-based Work America Capital led the round, and Mainline will use the funds to grow its platform, event management customer base, and marketing efforts, as well as to hire developers, marketing, and sales talent.

"The world of esports and gaming is exploding; however, continuity in tournament organization is lacking, keeping the sport from really taking off in other viable and exciting markets," says Chris Buckner, Mainline CEO, in a news release. "Mainline gives brands the tools they need to run powerful esports programs that will evolve the quickly maturing industry to the benefit of players, students, and the greater esports ecosystem."

Mainline, which spun off its sports engagement business earlier this year into a company now called Truss, created a white-labeled tournament platform for esports that's used by various clients across the industry and was instrumental to ESPN's inaugural Collegiate Esports Championship that was hosted in Houston earlier this year.

Work America Capital has supported sports technology in town before — including Houston-based Integrated Bionics, which has developed a GPS- and video-optimized sensor used by athletes around the world.

"As with any industry that takes off like a rocket, problems arise that must be solved through innovation," says Mark Toon, managing partner of Work America Capital, in the release. "Mainline is standardizing, organizing and optimizing the esports industry, paving the way for more players, more teams, more money and bigger, better tournaments."

Mainline is focused on expanding its services as esports continues to grow. According to the release, the total industry revenue for this year is expected to reach $1.1 billion worldwide, and viewership numbers have jumped from 335 million to 454 million in just two years.

"The strategic vision of Mainline puts them in the driver's seat with a consistent platform across amateur, collegiate and professional competitions," says Toon. "Given Mainline's partnerships and customers, they have paved a way to grow quickly across all sports and into other markets. We are excited to dedicate our time, resources and capital to the company."

Homecoming

The Cannon is finally getting to move its 150 startups and partners into its 120,000-square-foot campus in West Houston.

The original plan was to open in March, but construction, which began in April 2018, faced a series of setbacks due to weather. Current grand opening celebration plans are expected to be in September.

The flagship building is just the first step developing the campus, which is dubbed the Founders District.

"Our team has worked tirelessly to build this community over the past eighteen months, and we are incredibly proud to see our vision coming to life with the completion of this building," says The Cannon's CEO Lawson Gow in a news release. "The work isn't over though, and The Cannon will continue to grow our network of resources and locations to cater to the needs of Houston's growing entrepreneurial community." (Gow is the son of David Gow, owner of InnovationMap's parent company Gow Media.)

The building is currently 88 percent leased. Cannon Ventures, the company's investor group, will operate out of the new building, as will Capital Factory's Houston outpost. Austin-based Capital Factory, a statewide startup accelerator announced it would have its Houston operations at The Cannon in May. Since then, the company hired two Houston-based employees to run the programming.

According to the release, The Cannon will continue to grow its community relations for a "full suite" of partners. Houston-based investment fund Work America Capital, which led The Cannon's initial fundraising round, will also be joining The Cannon's community in the new building.

"It has been incredible to watch The Cannon's exceptional growth from inception two years ago to the vibrant community they've built today," says Mark Toon, managing partner of Work America Capital, in the release. "We can't wait to see the progress first-hand as The Cannon continues to establish themselves as a leader in building entrepreneurial communities."

The Cannon previously operated out of a 20,000-square-foot adjacent building called "The Waiting Room," which will be torn down and the space will be used as a part of the bigger Founders District plan.

The Cannon's new space will feature:

  • A 16-TV video wall
  • Outdoor courtyard
  • Movie theater
  • Snacks, coffee, and beer
  • Office needs, such as printers, scanners, and mail services
  • Showers
  • 24/7 accessibility
  • Professional and social events are organized on an ongoing basis for the community
  • Private event hosting for both members and non-members

The Greater Houston Partnership notes the Houston area soon will welcome its 28th Fortune 500 company. Expand Energy (formerly Chesapeake Energy), appearing at No. 362 on the 2026 list, says it’s moving its headquarters from Oklahoma City to Spring this year.

As the natural gas producer prepares to relocate to Texas, it’s hunting for a new leader. Nick Dell’Osso stepped down as president and CEO earlier this year. Board Chairman Michael Wichterich is interim president and CEO.

Dell’Osso became president and CEO of Oklahoma City-based Gulfport Energy effective May 28.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.

NASA unveils Artemis III astronauts at Johnson Space Center in Houston

To the moon

NASA on Tuesday, June 9, revealed the crew for its Artemis III mission, the next step in the space agency's plan to eventually land astronauts on the moon.

The announcement came two months after Artemis II's record-breaking trip around the moon that surpassed the distance record of Apollo 13.

NASA's Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency's Luca Parmitano won't fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with two lunar landers.

“To the Artemis III crew, we wish you Godspeed on the journey ahead,” said NASA administrator Jared Isaacman.

Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin are racing to deliver the lunar landers. The two-week demo is targeted for 2027. Blue Origin suffered a recent setback when its massive rocket exploded during an engine-firing test on the launch pad in Florida, shaking nearby homes and illuminating the sky with an orange fireball.

NASA's Jeremy Parsons said the setback is a learning opportunity and that the space agency is confident Blue Origin's rocket will be ready in time.

NASA's Artemis program aims to return astronauts to the moon's surface for the first time since the 1970s. A recent revamp of the program announced by Isaacman aims to fast-track it similarly to the Apollo era, adding the upcoming spaceflight around Earth before eyeing a lunar landing in 2028.

“We are certainly humbled as a crew to be able to be your crew that executes this Artemis III mission in space,” said Bresnik, Artemis III commander.

Added Douglas, mission specialist: “My brain — it is going a mile a minute right now. But my heart, it is so warm. It is so full."

In May, NASA awarded hundreds of millions of dollars in contracts to four companies, including Blue Origin, to build landers, rovers and drones for a future moon base. Isaacman said the goal of the moon base is to lay the foundation for a Mars expedition.
