As we’ve stated, they share four children together, who they welcomed via IVF and surrogacy. Back in 2021, Musk and Zilis welcomed twins via surrogate, named Azure and Strider. They welcomed a daughter named Arcadia in Feb 2024. On Feb 2025, they announced that they welcomed their fourth child together, a son named Seldon Lycurgus.

Musk's partner, Neuralink executive Shivon Zilis, announced that they had welcomed their fourth child together, Seldon Lycurgus Musk. This marks Musk’s 14th known child, reinforcing his publicly stated belief in combating the "underpopulation crisis" by having as many children as possible.

After Shivon Zilis announced the birth of her son with Elon Musk, a Wikipedia entry highlighting her Punjabi roots quickly gained traction online.
