• Kai Musk (Born 2006): Triplet son.
• Saxon Musk (Born 2006): Triplet son.

Children with Grimes (3 Children)

The relationship between Musk and the avant-garde musician Claire Boucher, known as Grimes, produced three children whose names are perhaps the most famous—and most challenging to pronounce—in the world. These unique names are a nod to mathematics, technology, and space exploration.

• X Æ A-Xii (X, Born May 2020): Originally named X Æ A-12, the name was slightly modified to comply with California law. Grimes has explained the name as: 'X' for the unknown variable, 'Æ' for the elven spelling of AI (artificial intelligence), and 'A-Xii' for the Archangel-12, their favorite aircraft.
• Exa Dark Sideræl Musk (Y, Born December 2021): Born via surrogate, this daughter’s name is often shortened to ‘Y.’ 'Exa' references the supercomputing term exaFLOPS, 'Dark' refers to the unknown, and 'Sideræl' is an elven spelling of sidereal, meaning true time of the universe, or star time.
• Techno Mechanicus (Tau, Confirmed 2023): Often referred to as ‘Tau,’ the name was revealed in a biography of Musk. The name continues the theme of technology and mechanics, reflecting Musk’s professional interests.

Children with Shivon Zilis (4 Children)

Shivon Zilis, a high-ranking executive at Musk's Neuralink company, is the mother of four of his children. The births of the first two were kept private until court documents were made public in 2022. The two most recent additions were announced in 2024 and early 2025, respectively, confirming a total of four children with Zilis.

• Strider Zilis Musk (Born November 2021): Twin son.
• Azure Zilis Musk (Born November 2021): Twin daughter.
• Arcadia Musk (Born 2024): Confirmed by Musk, this child was a private addition until media reports.
• Seldon Lycurgus Musk (Announced February 2025): The most recently announced child with Zilis, Seldon Lycurgus brings the total with Zilis to four.

Child with Ashley St. Clair (1 Child)

In a surprising development, conservative journalist and social media personality Ashley St. Clair announced in February 2025 that she had welcomed a child with Musk in September 2024. This revelation added the 14th child to the Musk family lineage.

• Unnamed Child (Born September 2024): As of the most recent announcements, the name of this child has not been publicly revealed. The announcement, made by St. Clair on social media, confirmed the birth but maintained privacy regarding the child’s name.

The Deeper Meaning Behind the Futuristic and Unique Names

The names chosen for Musk’s children are far from traditional, often blending elements of science, mythology, and technology. This trend is most evident in the children he shares with Grimes, but the recent names with Zilis—Strider, Azure, Arcadia, and Seldon Lycurgus—also carry significant weight.

Technology and AI References

The names X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus are direct reflections of Musk's core business interests. 'X' and 'Y' are common variables in mathematics and science, while 'Exa' and 'Techno' reference computing power and engineering. This naming convention is seen by many as a statement, symbolizing a desire for his children to embody the future he is actively trying to build through companies like Tesla and Neuralink.

The Name Change of Vivian Jenna Wilson

One of the most widely reported stories surrounding his children is the legal transition of his oldest daughter, Vivian. Her choice to change her name to Vivian Jenna Wilson and sever ties with her father's surname highlights the complexities and personal challenges of growing up in the spotlight of one of the world's most powerful men. The name change was granted in 2022, marking a clear and public separation from the 'Musk' identity.

The Impact of Elon Musk's Stance on Population

Elon Musk has consistently expressed concern about declining birth rates and the potential for a "population collapse," often stating that he is doing his part to help solve the crisis. The continuous expansion of his family—with 14 children across four mothers—is seen by many as a direct, real-world application of his public philosophy. He has repeatedly stressed the importance of having children for the sake of civilization, a belief that underscores his personal choices in family planning.

The sheer number of children, and the recent, rapid additions in 2024 and 2025, ensure that the Musk family will remain a topic of intense global discussion. Whether one views his choices as eccentric, controversial, or a necessary example, the legacy of his 14 children and their unique, often profound names is undeniably a major part of the Elon Musk story. The world will continue to watch as the youngest ‘Musk-eteers’—Seldon Lycurgus and the unnamed child with Ashley St. Clair—grow up under the shadow of their influential father.
