Elon Musk has 14 publicly known children born between 2002 and 2025 with four different partners: Justine Wilson, Grimes, Shivon Zilis, and Ashley St. Clair. Out of these 14 children, 13 are living. His large family spans multiple relationship eras, beginning with his first marriage to author Justine Wilson, moving through his relationship with musician Grimes, his family with Neuralink executive Shivon Zilis, and an addition involving author Ashley St. Clair.
Keeping track of this expanding family tree requires looking at each branch individually, as births have often been kept private or announced long after the fact.
The Family Branch with Justine Wilson
Musk married Canadian author Justine Wilson in 2000. Together, they welcomed six children, starting with their firstborn, Nevada Alexander Musk, in 2002. Tragically, Nevada passed away from sudden infant death syndrome (SIDS) at 10 weeks old.
Following this loss, the couple utilized IVF to expand their family. They welcomed twins Griffin and Vivian Jenna Wilson (born Xavier Alexander Musk) in April 2004. Vivian legally changed her name and gender in 2022, cutting public ties with her father. Two years later, in January 2006, Justine gave birth to triplet sons: Kai, Saxon, and Damian. Elon and Justine divorced in 2008, agreeing to share custody of the children. To read more about the context here, Associated Press provides an in-depth breakdown.

More details on early family dynamics can be found through historical archives on Wikipedia.
The Children with Grimes
Musk's high-profile relationship with Canadian musician Claire Boucher, known as Grimes, produced three children. Their unconventional naming choices gained massive media attention.
The first child, a son born on May 4, 2020, was originally named X Æ A-12, later adjusted to X Æ A-Xii (nicknamed "X") to comply with California naming laws. Their second child, a daughter named Exa Dark Sideræl Musk (nicknamed "Y"), was born via surrogate in December 2021. Their third child, a son named Techno Mechanicus (nicknamed "Tau"), was born quietly and revealed later through biographical details.
- X Æ A-Xii (Born May 2020)
- Exa Dark Sideræl Musk (Born December 2021)
- Techno Mechanicus (Born 2022)
The Children with Shivon Zilis
Shivon Zilis, an executive at Neuralink, shares four children with Musk. The existence of the first two children—twins born in November 2021 named Strider and Azure—became public knowledge in 2022 during court filings to update their last names.
Since then, Zilis and Musk have welcomed two more children. A daughter named Arcadia was born on February 28, 2024, followed by a son named Seldon Lycurgus, born on February 28, 2025. Official updates regarding corporate leadership and governance contexts are regularly tracked via outlets like Reuters.
- Strider Musk (Born November 2021, twin)
- Azure Musk (Born November 2021, twin)
- Arcadia Musk (Born February 2024)
- Seldon Lycurgus Musk (Born February 2025)
The Child with Ashley St. Clair
In late 2024, author and political commentator Ashley St. Clair welcomed a son named Romulus. Public disclosure of the birth came via social media in early 2025, and subsequent investigative reporting confirmed Musk as the father.

Common Misconceptions and Naming Conventions
People often assume Musk's naming conventions follow a rigid template, but they actually reflect personal interests ranging from medieval history and computing terms to aerospace design. For example, "Exa" refers to the computing term exaFLOPS, while "Sideræl" relates to deep space time.
Another common point of confusion involves the total count. Because several births were kept entirely private for months or years—such as the 2021 twins and Techno Mechanicus—media tallies frequently lag behind reality.
