Elon Musk and Shivon Zilis, an executive at Neuralink, have welcomed their fourth child together, a son named Seldon Lycurgus. This brings Musk’s total number of children to 14. The announcement was made by Zilis on the social media platform X, where she expressed her joy over the new addition. Musk responded to the post with a heart emoji.

Musk and Zilis previously welcomed twins, Strider and Azure, in 2021, and a daughter, Arcadia, in 2024. In addition to his children with Zilis, Musk has fathered children with other partners, including twins born in 2021 with Zilis and three children with musician Grimes.

Recently, Musk has been involved in a legal dispute with author Ashley St. Clair, who claims he is the father of her 5-month-old son and is seeking sole custody. A court has ordered Musk to appear in New York City on May 29 regarding this matter.
