Musk Wants to Rename SpaceXAI Again. The AI Brand Barely Survived a Quarter

Elon Musk’s artificial intelligence (AI) company took the name SpaceXAI on July 6. Ninety days later, Musk says that name is going too.

The new name is SpaceXSI. The SI stands for Super Intelligence, a phrase President Donald Trump now wants Washington to use instead of AI.

3 Posts on X Started the SpaceXAI Name Change

It began with three short lines. “No more AI,” Musk posted early Sunday. Then “SI.” Then “It’s better.”

Elon Musk also referred to SpaceX as “a super intelligence company.”

Notably, however, nothing else has changed. The website and social accounts still said SpaceXAI as of this writing. There is no date and no word on the legal name.

Musk Signed Trump’s AI Pact 5 Days Before Saying “No More AI”

Washington moved first. On September 29, Trump signed an order telling federal agencies to swap AI for SI in letters, reports, and websites.

The wording leaves little room.

“…the executive branch… will not acknowledge the usage of “Artificial Intelligence” and “AI” in any applicable setting,” read an excerpt in the White House order.

The White House argues that “artificial” makes the technology sound like a copy of human thinking.

That same day, Musk signed a voluntary safety pact at the White House. The bosses of Nvidia, Google, OpenAI, Meta, and Anthropic signed too.

BeInCrypto flagged the shift early. On September 29, Polymarket traders priced a 53% chance of an AI rename by September 30. Polymarket lets users bet on real-world events. Trump signed the order that day.

Stock investors now own this brand too. SpaceX listed on Nasdaq as SPCX on June 12, raising $75 billion at a $1.77 trillion valuation.

Its AI arm makes Grok, the chatbot built into X. This year it went from xAI to SpaceXAI. SpaceXSI would be its third name.

The next marker comes in late November. By then, Trump’s science adviser must propose a law defining Super Intelligence.
