xAI Is Dead. Long Live SpaceXAI

Artificial Intelligence xAI Is Dead. Long Live SpaceXAI I never have to type out what the hell "xAI" is again. 6, 2026, pm ET Reading time 2 minutes © SpaceXAI / X post Read Later Read Later Comments (9) In an effort to save tech bloggers from a lot of annoying typing, xAI has finally been rebranded: We are now @SpaceXAI. pic. twitter. com/ema66xDWC9 — SpaceXAI (@SpaceXAI) July 6, 2026   I’m elated. Do you have any idea how much I’ve dreaded writing about “xAI,” with its leading lowercase letter? How much I loathed explaining that the Elon Musk-owned operator of the Grok chatbot was acquired -owned SpaceX back in February, before SpaceX became publicly-traded last month? The animation in SpaceXAI’s X post (did I forget to mention that SpaceXAI owns X?) is, sure, embarrassing, aesthetically speaking. Watch in awe as the xAI logo, which looked like it was made ten minutes before it was due in graphic design class, contorts into the famously gorgeous and beloved styling of the SpaceX logo—a breathtaking metamorphosis. Now you have to squint to even AI part. But, logo aside, it’s a massive win for clarity. I no longer have to explain anything.  In March, Elon Musk said SpaceXAI’s signature product, Grok, was so flawed that it needed to be “rebuilt from the foundations up.” SpaceX then began the process of buying Cursor, an AI coding tool. Since then, Musk has claimed that Grok is progressing toward a “major improvement.” Grok foundation model V9-Medium (1.5T) has finished training. A lot of Cursor data was added in supplementary training and there is . Fine-tuning is underway and reinforcement learning begins in a few days. 2 to 3 weeks to public release. This will… — Elon Musk (@elonmusk) May 25, 2026   Last year, the company then called xAI reportedly spent $6.4 billion—twice its revenue. However, the AI division of SpaceX is absolutely critical to Elon Musk’s narrative about SpaceX’s future as a world-historically massive company with a “total addressable market” of $28.5 trillion. In this story, space infrastructure and space exploration are meant to be inextricably linked to AI. The SpaceX prospectus puts it in these terms: We believe AI infrastructure in space can utilize the virtually limitless power of the Sun and thereby enable the use of AI as a transformative force for understanding the universe and improving the daily lives of all humans. Elon Musk has also rattled off a version of this concept in oratory form, as he did during an all-hands meeting of xAI workers in February.
