Who Is X Æ A-Xii Musk?
X Æ A-Xii Musk is the first child of Elon Musk and Grimes. Elon Musk is known for Tesla, SpaceX, Neuralink, X, and several other companies, while Grimes, whose real name is Claire Boucher, is a Canadian musician and artist.
People reports that Elon Musk and Grimes welcomed three children together: X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus. Their first child, X, was born in May 2020, followed by Exa in December 2021 and Techno in June 2022.
Although X is still a young child, he has appeared with his father at several public events. That is one reason searches around X Musk age, Elon Musk child X, and Grimes son keep rising. When he appears in a photo or video with Elon Musk, people often want to know how old he is and how to say his name.
Why Is Elon Musk’s Son Called X?
Yes, Elon Musk’s son is called X. His full legal-style name is X Æ A-Xii Musk, but X is the short version used by his parents and by many media outlets.
The nickname makes sense because the full name is hard for many people to read at first glance. Instead of writing or saying X Æ A-Xii every time, people usually shorten it to X Musk.
There is also another reason the name feels very connected to Elon Musk. The letter X appears often in Musk’s business world. He co-founded X.com, later renamed Twitter as X, and has also used the letter in SpaceX. So when people hear X Musk real name or Elon Musk son name, they often connect it back to Musk’s long-running interest in the letter X.
X Æ A-12 vs X Æ A-Xii: Why His Name Changed
At birth, Elon Musk and Grimes first introduced their son’s name as X Æ A-12 Musk. Later, the name was changed to X Æ A-Xii Musk.
The main difference is the final part. The original name used the number 12, while the updated version uses Xii, which represents 12 in Roman numerals. People reports that Musk and Grimes changed the name because they needed to remove the numbers to meet California naming rules.
That is why you may still see both versions online:
X Æ A-12
X Æ A-Xii
Both names refer to the same child. The first version is the original name that went viral in 2020, while X Æ A-Xii Musk is the later version most commonly used now.

In simple words, the name blends science, technology, art, aircraft history, and personal meaning. That is very much in line with how both Elon Musk and Grimes are seen publicly. Musk is tied to rockets, electric cars, AI, and engineering, while Grimes is known for experimental music, sci-fi visuals, and futuristic creative ideas.
For readers searching X Musk name meaning, the easiest way to understand it is this: the name was designed to feel symbolic, personal, and futuristic rather than traditional.
