SpaceX says it’s building its largest spaceport yet, committing $100 billion for a Louisiana site—adding to its list of billion-dollar expansion plans

Rather apparent in SpaceX’s IPO filings is the ever-constant named goal of reaching Mars to build compute infrastructure and even human settlements on the red planet.

In Elon Musk’s first earnings call, he reiterated those goals , the very ones that led him to create the company over two decades ago.

Now he’s expanding his lofty space travel aspirations with a new real-estate and infrastructure investment.

SpaceX is committing $100 billion to build a massive new spaceport in coastal Louisiana, giving the rocket company another multibillion-dollar expansion project as it races to scale Starship, satellite manufacturing and AI infrastructure.

The facility, called Starbase Louisiana, will occupy roughly 125,000 acres on Pecan Island in Vermilion Parish and is expected to become the fourth and largest of SpaceX’s launch complexes.

Construction is scheduled to begin in 2027, with the first launch targeted for as early as 2029.

At full buildout, the site is expected to contain five launch facilties—each with two launch pads—along with propellant farms, a propellant-production facility, power generation, vehicle-processing facilities and housing for employees and their families.

“Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth,” Musk posted on X.

That claim is about launch capacity, not land.

By physical footprint, the current record holder is Russia’s Baikonur Cosmodrome in Kazakhstan, sprawling across roughly 6,717 square kilometers—more than 13 times the size of SpaceX’s planned Louisiana site.

What Musk and Louisiana officials mean by “biggest launch site on Earth” is cadence: Starbase Louisiana is designed for more than a dozen launch towers and over 30 Starship flights a day, a pace no existing spaceport, including Baikonur, comes close to matching.

Louisiana Economic Development estimates SpaceX will create more than 3,000 direct jobs over the next decade, with an average annual salary of $92,600, as well as roughly 8,100 indirect jobs—leading to more than 11,100 new job opportunities in Acadiana.
