Neuralink executive Shivon Zilis has officially revealed the name of her fourth child with the head of US Department of Government Efficiency (DOGE) billionaire entrepreneur Elon Musk. In a heartfelt social media post, Zilis shared the news while celebrating the first birthday of their third child, Arcadia. Zilis, who has largely kept details about her children out of the public eye, confirmed that their fourth child is named Seldon Lycurgus. The announcement marks the first time she and Musk have publicly acknowledged their son’s name.
“Discussed with Elon, and in light of beautiful Arcadia’s birthday, we felt it was better 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,” Zilis wrote in her post on X (formerly Twitter). Musk reacted to the post with a heart emoji.

Reports indicate that Arcadia was born in early 2024, but until now, the couple had kept both their third and fourth child’s identities under wraps.
Musk’s Expanding Family And Controversies
Elon Musk, the CEO of Tesla and SpaceX, has fathered at least 13 children, including four with Zilis. Musk’s parenting has often drawn public attention, not just for the sheer size of his family but also for the surrounding controversies.
His former partner, musician Grimes, has previously accused him of neglecting one of their children’s medical needs. Meanwhile, influencer Ashley St Clair recently claimed she gave birth to Musk’s child five months ago — a claim he has yet to confirm or deny.
Musk’s journey as a father began in 2002 when he and his first wife, Justine Wilson, welcomed their son, Nevada Alexander Musk, who passed away as an infant. The couple later had twins and triplets through IVF. Since then, Musk has expanded his family with multiple partners, making headlines for his unconventional approach to parenthood.
Here are the names of 13 children of Elon Musk:
Nevada Alexander Musk, Griffin, Vivian, Kai, Saxon, Damian, X AE A-XII, Exa Dark Siderael, Strider, Azure, Techno Mechanicus, Arcadia, and Seldon Lycurgus. A 14th child was born before Seldon, but the name is not known to the world at this point.
