X, the social media company formerly known as Twitter, has announced that it will shut down its San Francisco headquarters.

Sources close to the company revealed to Fortune.com that X’s employees received an email notice about the impending closure. The company’s San Francisco office on Market Street will cease operations on Friday, September 13.

This change by the social media company marks another major milestone in Elon Musk’s business transition from California to Texas.

As previously reported by The Dallas Express, Musk recently posted on X a series of business updates and explanations for recent changes, notably saying that he would move both SpaceX and X to Texas due to his various issues with the state of California.

“Have had enough of dodging gangs of violent drug addicts just to get in and out of the building,” Musk posted to X earlier this year.

The announcement also followed California Gov. Gavin Newsom’s signing of a contentious bill that prohibits schools from informing parents if their child is transgender.

“This is the Final Straw. Because of this law and the many others that preceded it, attacking both families and companies, SpaceX will now move its HQ from Hawthorne, California, to Starbase, Texas,” Musk added. 

Musk has long been vocal about his discontent with various California state policies. This move follows his 2021 decision to relocate Tesla’s manufacturing plant from California to Austin, which was driven by past conflicts over COVID-19 restrictions in the state.

As highlighted in a previous report from The Dallas Express, Texas has increasingly become a central hub for Elon Musk’s businesses since the move in 2021.

Earlier this year, Tesla shareholders formally approved the move of the company’s legal headquarters to Texas. A poll on X showed strong support for the relocation, with 87.1% of participants in favor.
