Elon Musk Confirms SpaceXAI Rebrand to SpaceXSI as Trump Pushes Super Intelligence Terminology

Elon Musk Commits to SpaceXSI Rebrand

Elon Musk confirmed on Sunday that SpaceX's AI unit will be renamed SpaceXSI, marking a significant shift in how the company positions its artificial intelligence capabilities1

1

. Responding to a user on X (formerly Twitter), Musk stated, "Yes, we will make that change," signaling his commitment to align with President Donald Trump's push to replace artificial intelligence terminology with super intelligence across the industry2

Trump's Executive Order Drives Terminology Shift

The decision to rename SpaceXAI to SpaceXSI follows Donald Trump's executive order signed on September 29, 2026, which directs federal agencies to replace artificial intelligence with super intelligence or SI on official websites, policy documents, and government press releases3

3

. In a speech to the UN General Assembly last month, Trump declared: "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"2

2

. The White House executive order states that the name super intelligence conveys the true capabilities of technologies being developed today, unlocking new forms of human creativity and empowering Americans to achieve what was previously impossible3

SpaceX Declares Itself a Super Intelligence Company

Musk has gone beyond simply accepting the terminology change, declaring that "SpaceX is a super intelligence company"4

4

. This isn't the company's first name change—xAI was officially rebranded as SpaceXAI in July, five months after SpaceX acquired it, bringing Grok and other AI products under the SpaceX banner3

3

. SpaceX, together with xAI and X, went public in June at a valuation of about $2.1 trillion3

3

. Musk has already adopted the new language in practice, reportedly saying "AI" while standing next to Trump on Tuesday before correcting himself to say "SI"3

Super Intelligence Accord and Industry Alignment

Following a White House meeting last week, top tech leaders signed a "morally binding" Super Intelligence accord to establish voluntary safety standards for the AI industry3

3

. The one-page document was signed by six tech bosses of firms building key frontier models and hardware: Google CEO Sundar Pichai, Anthropic CEO Dario Amodei, Meta CEO Mark Zuckerberg, OpenAI President Greg Brockman, xAI CEO Elon Musk, and NVIDIA CEO Jensen Huang3

3

. Although not legally enforceable, the agreement leaves open the possibility of incorporating its measures into laws or regulations in the future, establishing a framework for AI governance across the industry3

3

. President Trump has also announced the Super Intelligence Force (SIF) initiative, which would liaise between the federal government and the wider industry on SI4

Terafab Project and TSMC Collaboration

As the rebranding unfolds, Musk revealed that SpaceX and Tesla are exploring cooperation with TSMC on the massive Terafab project4

4

. The Terafab aims to produce at least 1 terawatt of AI compute per year for Optimus robots, self-driving cars, and space-based AI data centers4

4

. Phase one is currently being built in Grimes County, Texas, with an initial capital outlay of $16.8 billion, though the full buildout might cost over $100 billion4

4

. Intel officially joined the Terafab initiative in April 2026, with plans to deploy its 14A cutting-edge process node and advanced packaging capabilities4

4

. TSMC is now mulling whether to operate a Texas fab, with Terafab serving as the anchor buyer through equity, purchase promises, or both, which would cement NVIDIA's dominance within SpaceXAI's compute infrastructure4
