Billionaire entrepreneur Elon Musk said Tuesday he is moving the headquarters of two of his companies, X Corp. and SpaceX, to Texas from California. SpaceX will relocate from Hawthorne, CA to southeast Texas, where SpaceX has been expanding its Starbase manufacturing and launch site, while X, formerly known as Twitter, will decamp from its longtime home in San Francisco to Austin.

The Wall Street Journal reported Tuesday that X has been expanding in Texas anyway. Earlier this year, the company said it was hiring employees for a team based in Austin to focus on content safety issues.

It’s not immediately clear what will happen to X’s headquarters complex in San Francisco, the WSJ reported. X may keep a presence in the area, which could lead to a setup similar to the one at Musk’s electric-vehicle company, Tesla, which is based in Texas but has an office called its “engineering headquarters” in Palo Alto, CA.

Similarly, SpaceX has magnified its presence in the Lone Star State, with Musk planning large-scale manufacturing facilities for SpaceX as well as Tesla and the Boring Company in the Austin metro area. Texas Gov. Greg Abbott reposted one of Musk’s tweets on X and said that the SpaceX move “cements Texas as the leader in space exploration.”
