The Roster of Unique Names and Their Meanings

Musk’s children with Grimes, the Canadian musician Claire Boucher, are perhaps the most famous due to their highly unusual and futuristic names. These names instantly became global talking points, reflecting the couple's interest in technology, space, and unique nomenclature.

X Æ A-Xii (X)

The first child of the couple, born in May 2020, was initially named X Æ A-12. Due to California state law prohibiting numbers in a legal name, it was later changed to X Æ A-Xii, with the 'A-Xii' being the Roman numeral version of A-12. * X: Represents the unknown variable. * Æ: Grimes stated this is the elven spelling of 'Ai' (love and/or artificial intelligence). * A-Xii: Refers to the Lockheed SR-71 Blackbird's predecessor, the Archangel-12, which Musk and Grimes call their favorite aircraft.

Exa Dark Sideræl Musk (Y)

Born via surrogate in December 2021, the couple's daughter was nicknamed 'Y' to match her older brother's single-letter moniker. Her full name is a blend of scientific and fantastical concepts. * Exa: A reference to exaFLOPS, a unit of computing performance. * Dark: Represents "the unknown," which Grimes described as "the beautiful mystery of our universe." * Sideræl: A more elven spelling of 'sidereal,' meaning relating to or determined by stars or constellations.

Techno Mechanicus (Tau)

The existence of the third child with Grimes, nicknamed Tau, was revealed in September 2023. The full name, Techno Mechanicus, continues the theme of technology and mechanics. * Techno: Likely a nod to technology, a core part of Musk’s career. * Mechanicus: Implies a connection to machines or the mechanical arts. * Tau: The Greek letter $\tau$, often used in physics and mathematics, is his simple nickname.

The Newest Additions: The Children with Shivon Zilis

The most recent confirmations of Musk's expanding family involve Shivon Zilis, a Canadian executive at his brain-chip company, Neuralink. Zilis and Musk had twins in 2021, and the news of a third and fourth child with her in 2024 brought the official count to 14. The twins, Strider and Azure, were born in November 2021, just weeks before his daughter Exa Dark Sideræl was born via surrogate to Grimes. The close timing of the births highlighted Musk's unconventional approach to family planning. The arrival of the third and fourth children with Zilis, Arcadia and Seldon, was confirmed in 2024, though the exact birth date of the 14th child remains private. This development underscores Musk’s personal mission to address what he views as a global population collapse, a theme he frequently discusses in public forums.

Elon Musk's Philosophy on Fatherhood and Population

Musk has often spoken publicly about the importance of having children, framing it as a duty to combat declining birth rates. He views his own large family as an example of this belief. His children are growing up across multiple households and mothers, a dynamic that is highly unusual for a public figure of his stature. The names of his children, from the relatively traditional (Griffin, Saxon, Damian) to the highly futuristic (X, Y, Tau), reflect the different periods and partners in his life. The sheer number of his offspring and the unique circumstances surrounding their births ensure that his family life will remain a topic of intense interest for years to come.
