The $1.1 billion Tesla Gigafactory in Southeast Travis County is growing each day as crews work to make good on Musk's promises: initial limited production by the end of the year and as many as 10,000 jobs. The construction site has attracted acolytes such as the Tesla Owners Austin and local elected officials as well as speculation.

🚘 Toured the Tesla site w/ some of my team on Friday! It's incredible to see how quickly it's coming together. I look forward to checking it out once it's complete. #GigaTexas pic.twitter.com/y1dEqwJFvu

The factory will produce the Model 3 sedan, Model Y SUV and Cybertruck, at least one of which has made its Central Texas debut. Tesla sold 201,250 cars in the second quarter, more than twice as many as it did in the same period last year, despite a global chip shortage, according to a July 2 press release.

In addition to construction, the electric carmaker is in the midst of a local hiring spree, with more than 250 Austin-based jobs posted on its website.

Although the factory is still under construction, questions are already swirling about future projects. The entity Tesla used to buy the site owns more than 2,500 acres along SH 130, according to a May 13 report by the Austin Business Journal. Experts suggested it could be used for Musk's other ventures or serve as the future home of Tesla HQ, following its founder from California to Texas.

SpaceX

Musk's aerospace company SpaceX is not currently hiring in the Austin area but does have scores of open positions in Brownsville and McGregor, where it has a launch facility and rocket development facility, respectively.

However, SpaceX will break ground on a new "state-of-the-art manufacturing facility" in Austin related to its broadband Starlink project, according to job listings posted in March.

Starlink is a forthcoming high-speed, low-latency broadband internet system enabled by a "constellation of low Earth satellites" and suited for populations with little or no connectivity, such as rural areas, according to its website.

It is unclear where the Austin facility will be located but it will manufacture consumer products such as Starlink dishes, Wi-Fi routers and mounting hardware, according to the postings, which are no longer listed.

The Boring Company

Musk's tunneling startup—and flamethrower manufacturer—is hiring for 18 Austin-based positions, according to its website. One job posting mentions a research and development site in Bastrop, marking the company's first admission that it has a location in the Austin area, as reported by the Austin Business Journal last month.

The Boring Company built a 1.14-mile research and development tunnel in Hawthorne, California, in 2018. It cost around $10 million to construct and originated at a SpaceX property, according to the website.

Neuralink

Musk's brain implant startup is also hiring in Austin. Its website lists seven positions, including a neurosurgical robot operator and veterinarian. The company has tested its product on monkeys and pigs, prompting pushback from PETA, and Musk tweeted in February that initial human trials could begin as soon as later this year.

Neuralink is working super hard to ensure implant safety & is in close communication with the FDA. If things go well, we might be able to do initial human trials later this year.

Although the company is headquartered in San Francisco, the postings have fueled speculation that it will expand to a new Austin location for months.

Musk Foundation

Musk's philanthropic venture relocated to Austin last summer, ahead of its founder's closely watched move from California to Texas. Founded in 2001, the foundation supports renewable energy, human space exploration, pediatric research, science and engineering education, and the development of artificial intelligence.

The Musk Foundation recently donated $1 million toward the revitalization of downtown Brownsville and new housing opportunities in the area, where SpaceX has a launch facility and is actively hiring.

Please consider moving to Starbase or greater Brownsville/South Padre area in Texas & encourage friends to do so!

SpaceX’s hiring needs for engineers, technicians, builders & essential support personnel of all kinds are growing rapidly.

"There's going to be a need for professionals to be able to have a home near downtown," Brownsville Community Improvement Corporation Executive Director Josh Mejia told Valley Central last month. "We understand that there have been folks who've lived here for many generations, so we'd also like to support that as well."

Musk announced in March that he would donate $20 million to school districts in Cameron County, where he is attempting to incorporate the new city of Starbase, and $10 million to the city of Brownsville. The donations have prompted some to wonder: Could Austin be next?
