In a heartwarming revelation on February 28, 2025, Shivon Zilis, a top executive at Neuralink, took to X to share the news of her fourth child with tech mogul Elon Musk—a son named Seldon Lycurgus.
The announcement, made on the same day as their daughter Arcadia’s birthday, marks Musk’s 14th child, further expanding his already extensive family.
Zilis’s post radiated pride and affection: “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 responded simply with a heart emoji, signaling his support for the announcement.
While the exact birth date of Seldon remains undisclosed, the timing suggests a deliberate choice to celebrate both children together, blending family milestones with public disclosure.
Seldon Lycurgus joins Musk and Zilis’s three other children: twins Strider and Azure, born in November 2021, and Arcadia, whose birth was confirmed earlier in 2024.
The couple’s growing brood reflects Musk’s well-documented stance as a “pronatalist,” advocating for higher birth rates to counter what he perceives as a looming population crisis. With Zilis, an AI expert and key figure in Musk’s Neuralink venture, this latest addition underscores their shared personal and professional orbit.
Musk’s family tree now spans 14 children across four women. He shares six children with his first wife, Justine Wilson—including twins Vivian and Griffin, and triplets Kai, Saxon, and Damian—though their firstborn, Nevada, tragically passed away in infancy. With singer Grimes, Musk has three children: X Æ A-12, Exa Dark Sideræl, and Techno Mechanicus. The 14th child announcement follows closely on the heels of a controversial claim by conservative influencer Ashley St. Clair, who, on February 14, 2025, asserted she had given birth to Musk’s 13th child, a son referred to as R.S.C., five months prior. St. Clair’s revelation sparked drama, including a custody lawsuit and public calls for Musk to acknowledge paternity, though he has yet to respond directly to her claims.
The timing of Zilis’s announcement has fueled speculation online, with some suggesting it overshadows St. Clair’s ongoing saga.
Regardless, Musk’s focus appears to remain on his expansive family vision. Seldon Lycurgus, described as a “juggernaut” with a “heart of gold,” is the latest chapter in a lineage that continues to captivate public attention—both for its scale and the unconventional names that define it.
As Musk juggles his roles at Tesla, SpaceX, and the Department of Government Efficiency, his personal life remains as dynamic as his professional one, with Seldon’s arrival marking yet another milestone in his extraordinary journey.
