Elon Musk, the billionaire entrepreneur and CEO of Tesla and SpaceX, has welcomed his 14th child, named Seldon Lycurgus Musk, with Neuralink executive Shivon Zilis. This announcement, made on February 28, 2025, coincided with the first birthday of their third child, Arcadia, and showcases Musk's growing family dynamic. Zilis posted on the social media platform X, saying, "Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was just to 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 responded with love emojis, showcasing their supportive co-parenting relationship.
This latest addition marks the couple’s fourth child together, strengthening Musk and Zilis's unconventional family structure. Their earlier children include twins Strider and Azure, born via IVF in November 2021, just weeks before Musk had his second child with musician Grimes.
Shivon Zilis and Musk’s private co-parenting arrangement began to reveal itself following the birth of their twins, who were disclosed when court documents surfaced. Initially low-profile, their relationship started to attract public attention when they welcomed Arcadia on February 28, 2024, just one year before their newest son was announced.
Alongside Zilis, Musk is also father to multiple children from previous relationships. With Grimes, he has three children: X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus. Their relationship has been rather tumultuous, with legal battles over custody and public disputes on social media garnering significant media attention.
Musk’s family dynamics were complicated recently when conservative influencer Ashley St. Clair came forward, claiming she has also had Musk’s child, born around September 2024. St. Clair filed for sole custody of their son, identified with the initials R.S.C. She claims Musk has not played an active role since the child’s birth, stating, "I am, and always have been, the only parent and caretaker."
St. Clair's allegations have sparked controversy, questioning the billionaire's commitment to his growing family. To date, Musk has not publicly acknowledged St. Clair's claims beyond making occasional posts on X about the situation.
Musk’s commitment to fatherhood goes beyond just these personal relationships. He has publicly stated his belief in combating the global underpopulation crisis, asserting, "The greatest threat civilization faces is declining birth rates" and stressing the importance of growing families. According to reports, he aims to have as many children as possible to contribute to human genealogy, stating, "Bravo to big families!" This perspective aligns with his previous actions—he continues to father children across multiple households, using resources such as IVF facilitated by his partners.
Musk’s family, now including his 14 children scattered among three partners, reflects both complexity and diversity. His first marriage with Canadian author Justine Wilson ended amid personal tragedies, including the loss of their first child, Nevada, shortly after birth. The couple later had twins Griffin and Vivian, followed by triplets Kai, Saxon, and Damian, significantly shaping Musk’s approach to family.
With Grimes, the narrative took on another layer. Their relationship often fluctuated, showcasing artistic and intellectual chemistry marred by legal conflicts over their three children. Their unusual names reflect their artistic temperament, with X Æ A-Xii conveying creativity and innovation.
Shivon Zilis stands apart as the quieter presence within Musk’s circle, yet she shares parenting of several children with him and helps manage the blend of his extended family. The growing visibility of her role has led to public speculation, particularly as both Zilis and Musk were seen together at high-profile events, including meetings with global leaders.
Despite the challenges of parenting across various households, Musk seemingly manages to nurture relationships and coordinate family gatherings. Zilis recently expressed hope for creating connection between the relatives, even as past tensions arose due to differing parenting styles.
While Musk’s parenting philosophies may draw criticism from some quarters, those close to him suggest he is committed to fostering meaningful relationships with his children. A source close to Musk stated, "He really loves Shivon," implying depth beyond what’s publicly known.
Musk’s family dynamics paint a unique portrait of modern-day parenthood, where personal ambitions interweave with family obligations, creating new narratives around parenting responsibilities and societal expectations. Despite the media firestorms surrounding his family, Musk remains dedicated to his role as father across his extended and diverse family, committed to preserving connections among his significant progeny.
Overall, Musk's latest announcement about having Seldon alongside the rapid developments with St. Clair adds layers to the complex nature of his family tree, showing how fame intertwines with private commitments. With various relationships and children across the spectrum, Musk embodies the avant-garde of 21st-century parenting, encouraging big families as part of his life philosophy.
