Elon Musk said SpaceX will change the name SpaceXAI to SpaceXSI, but he gave no timetable. The announcement points to a terminology change: “SI” refers to “super intelligence.” It does not confirm that the rebrand is complete or that SpaceX’s products or technical work are changing.
What did Elon Musk announce?
On October 4, 2026, Musk, identified by Reuters as SpaceX’s CEO, replied to a user on X who asked whether SpaceXAI would be renamed SpaceXSI. Reuters reported his answer: “Yes, we will make that change.” He offered no further details or implementation date.
What does “SI” mean?
In the reports, SI means “super intelligence.” Euronews reported that Musk had posted, “No more AI. SI. It’s better,” before confirming the name change.
Why is SpaceXAI changing its name?
The reported context is a public push to use “super intelligence” instead of “artificial intelligence.” Reuters connected Musk’s announcement to U.S. President Donald Trump’s advocacy for that terminology. In his UN General Assembly speech, Trump said, as quoted by Reuters: “From this point forward, all of United States documents, and hopefully the world’s will be changed to use the much more accurate term ’super’ as opposed to artificial. So it’s super intelligence.”

Has SpaceXAI officially changed its name yet?
The announcement confirmed an intention to make the change, not that it had been completed.

That is a time-specific status report, not confirmation of the account’s status at a later date.
