Elon Musk Welcomes Baby No. 4 with Shivon Zilis, His 14th Child! Here's the Complete List of His Children and Their Mothers

Elon Musk Welcomes Baby No. 4 with Shivon Zilis, His 14th Child! Here's the Complete List of His Children and Their Mothers

Elon Musk, the billionaire entrepreneur, has welcomed another addition to his growing family. On February 28, 2025, Shivon Zilis, the executive at Neuralink, announced the birth of their fourth child, Seldon Lycurgus. The announcement came on the first birthday of their daughter, Arcadia. Musk, who now has at least 14 children, has long spoken about the importance of increasing birth rates. Meanwhile, another controversy has surfaced, as conservative influencer Ashley St. Clair has publicly claimed Musk is the father of her child.

New Addition to Musk's Family

Zilis, a prominent AI expert, shared the news on X (formerly Twitter), saying, "Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was better to also just share directly about our wonderful and incredible son Seldon Lycurgus. Built like a juggernaut, with a solid heart of gold. Love him so much." Musk simply responded with a heart emoji.

This new chapter in Musk's personal life aligns with his views on procreation, which he has often described as a societal responsibility.

A Private Yet Public Life

Musk and Zilis previously welcomed twins, Strider and Azure, in 2021 through IVF. Their third child, Arcadia, was born in 2024, and Musk confirmed the birth months later. Musk noted at the time, "All our friends and family know. Failure to issue a press release, which would be bizarre, does not mean ‘secret.’"

Zilis has discussed her decision to have children with Musk in Walter Isaacson’s biography Elon Musk, explaining, “He really wants smart people to have kids, so he encouraged me to. If the choice is between an anonymous sperm donor or doing it with the person you admire most in the world, for me that was a pretty f--king easy decision.”

A New Paternity Claim: Ashley St. Clair's Allegations

Zilis’ announcement comes just weeks after conservative influencer Ashley St. Clair claimed Musk is also the father of her child. On February 14, 2025, St. Clair wrote on X: "Five months ago, I welcomed a new baby into the world. Elon Musk is the father. I have not previously disclosed this to protect our child’s privacy and safety, but in recent days it has become clear that the tabloid media intends to do so, regardless of the harm it will cause.”

St. Clair has filed a paternity petition seeking to have Musk legally recognized as the father and is requesting sole custody. Her representative, Brian Glicklich, stated, “Ashley & Elon have been privately working towards the creation of an agreement about raising their child for some time. We are waiting for Elon to publicly acknowledge his parental role with Ashley, to end unwarranted speculation.” Musk has yet to comment on this claim.

Musk’s Expanding Family Tree

Musk's personal life, much like his professional ventures, is complex. With his first wife, Canadian author Justine Wilson, Musk has six children: twins Griffin and Vivian, and triplets Kai, Saxon, and Damian. Tragically, their first child, Nevada, passed away from Sudden Infant Death Syndrome (SIDS) when he was 10 weeks old.

In 2022, Musk’s eldest child with Wilson, Vivian Jenna Wilson, made headlines by changing her name and gender and publicly distancing herself from her father.

Musk’s procreation philosophy is well-known. In 2022, he tweeted: "Doing my best to help the underpopulation crisis. A collapsing birth rate is the biggest danger civilization faces by far."

In 2020, Musk had X Æ A-Xii with singer Grimes, followed by two more children—Exa Dark Sideræl and Techno Mechanicus—via surrogate. However, the couple has been involved in legal disputes over custody.

Musk's children with Zilis include twins Strider Sekhar Sirius and Azure Astra Alice, born in 2021, and Arcadia, born in 2024. The latest addition to his family, Seldon Lycurgus, joins this growing group.

The Musk Family Tree: A Web of Relationships

Musk's family is equally complex. His mother, Maye Musk, a former dietitian and model, has played a significant role in his life. His father, Errol Musk, an engineer, has had a strained relationship with Elon, who has openly discussed their troubled past.

Musk's siblings include Kimbal Musk, a restaurateur and entrepreneur, and Tosca Musk, a filmmaker and founder of Passionflix.

Musk’s personal life, particularly his growing family, continues to spark public interest. As his family tree expands, the billionaire’s unconventional approach to family life remains a topic of conversation.

Whether Musk chooses to address the latest paternity claims or continue with his usual public silence, one thing is certain: his legacy will not only be defined by his groundbreaking work in technology and space but also by the growing number of names in his family tree.
