The Expanding Legacy: A Complete List Of Elon Musk’s 12 Confirmed Children And The Latest Claims Of 14

The world's most prolific billionaire, Elon Musk, has made headlines not only for his ventures in space exploration and electric vehicles but also for his rapidly expanding family. As of late 2025, the confirmed number of his children stands at 12, shared with three different women, though persistent, fresh claims suggest the true count may be as high as 14. This complexity, combined with the children's uniquely symbolic names and the public nature of their family dynamics, makes the Musk legacy a subject of intense curiosity and constant media scrutiny.

The Mothers: Justine Wilson, Grimes, and Shivon Zilis

Musk’s decision to have a large family has drawn significant attention to the three women who are the mothers of his children, each representing a distinct phase in his personal life and a unique dynamic.

Justine Wilson (First Wife and Mother of 5 Living Children)

Justine Wilson is a Canadian author and Musk’s first wife, whom he met while they were students at Queen's University in Ontario. They married in 2000. After the tragic loss of their first son, Nevada, they turned to IVF to have their subsequent five children: twins Griffin and Vivian (formerly Xavier), and triplets Kai, Saxon, and Damian. Wilson has been vocal about the challenges of co-parenting and the dynamics of their relationship following their 2008 divorce. Her continued presence in the children’s lives, particularly in supporting Vivian Jenna Wilson's name and gender change, remains a central part of the family narrative.

Grimes (Claire Boucher, Mother of 3 Children)

Grimes, a Canadian musician and artist, began dating Musk in 2018. Their relationship produced three children, all known for their highly unusual, technology- and sci-fi-inspired names: X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus. Their relationship timeline was famously on-again, off-again, with the births of their second and third children, Y and Tau, being kept secret for some time. The names themselves are a goldmine for topical authority, connecting to themes like Artificial Intelligence (AI), space exploration, and futuristic concepts, all core to Musk’s brand. The revelation of Techno Mechanicus (Tau) in the 2023 biography was one of the biggest family updates in recent years.

Shivon Zilis (Neuralink Executive and Mother of 3 Confirmed Children)

Shivon Zilis, a Canadian executive at Musk’s neurotechnology company, Neuralink, is the mother of three of his youngest children. She holds a significant role in the Musk ecosystem, being the director of operations and special projects at Neuralink and a board member at OpenAI. The twins, Strider and Azure, were born in November 2021, just before the birth of Exa Dark Sideræl. The quiet arrival of their third child in early 2024 brought the confirmed total to 12. This relationship highlights Musk’s belief in the necessity of a high birth rate, as Zilis and Musk have publicly discussed the importance of having children to address global population decline.

The Latest Claims: Is the Real Number 14?

While 12 children are widely confirmed and acknowledged, the most recent and unverified news circulating in late 2024 and 2025 suggests the number may be higher, potentially reaching 14. These claims add a layer of fresh controversy and speculation to the Musk family narrative.

The Arcadia and Seldon Lycurgus Claim

Some reports in 2024 and 2025 have listed two additional children, Arcadia and Seldon Lycurgus, as the third and fourth children with Shivon Zilis, separate from the twins Strider and Azure. This information has been inconsistent across major publications, with some sources listing them as the names of the third and fourth children with Zilis, while others maintain Zilis has only three. This discrepancy is a key element of the current, evolving story.

The Ashley St. Clair Claim

Separately, conservative journalist and influencer Ashley St. Clair publicly claimed in February 2025 to have given birth to a child by Elon Musk in September 2024. While this claim has not been officially confirmed by Musk, it is a significant, late-breaking development that, if verified, would push the total number to 14 children with four different partners. This ongoing speculation keeps the topic of Musk's family life highly relevant and constantly updated.

The Impact of the Musk Legacy and Topical Authority Entities

The lives of Elon Musk's children are inherently linked to his public persona and his companies. The names themselves serve as powerful topical authority entities, connecting the family to his professional and philosophical interests:

• X Æ A-Xii: Links to Artificial Intelligence (AI), aerospace, and the Lockheed A-12 Archangel aircraft.
• Exa Dark Sideræl: Connects to supercomputing and astrophysics concepts.
• Techno Mechanicus: A clear nod to futurism and technology.
• Vivian Jenna Wilson: Her legal separation and name change highlight issues of gender identity and family estrangement, topics that generate significant public discussion.
• Shivon Zilis: Her role as a Neuralink executive intertwines the family's story with Musk’s most ambitious brain-computer interface company.
• The use of IVF for the triplets and a surrogate for two of Grimes' children showcases the intersection of advanced reproductive technology and modern family planning.

This constantly evolving family tree, with its blend of public revelations, private moments, and unique nomenclature, ensures that the Musk legacy remains one of the most compelling and current stories in global media.
