Billionaire entrepreneur Elon Musk and Neuralink executive Shivon Zilis have welcomed their fourth child together, a son named Seldon Lycurgus. The news was confirmed recently, bringing Musk’s total known number of children to 14.
The Growing Musk-Zilis Family
Musk, 53, and Zilis, 38, have been expanding their family in recent years. The couple previously welcomed twins Strider and Azure in November 2021 and their third child, Arcadia, in 2024. While the couple has kept most details about their personal lives private, Zilis shared her excitement on social media, calling Seldon’s birth a "blessing beyond words."
The Name: Seldon Lycurgus
The name Seldon appears to be a reference to Hari Seldon, a character from Isaac Asimov’s Foundation series, known for predicting the future using mathematics. Musk has frequently expressed his admiration for Asimov’s work. The middle name Lycurgus could be a nod to the legendary Spartan lawmaker, reflecting Musk’s interest in history, governance, and human civilization.
Musk’s Expanding Family
With the birth of Seldon, Musk now has 14 children from multiple relationships:
- With Justine Wilson (his first wife)
- Twins Griffin and Vivian, born in 2004
- Triplets Kai, Saxon, and Damian, born in 2006
- Their firstborn son Nevada, tragically passed away as an infant in 2002.
- With Grimes (Claire Boucher)
- Son X Æ A-12, born in 2020
- Daughter Exa Dark Sideræl (Y), born in 2021
- Son Techno Mechanicus (Tau), born in 2022
- With Shivon Zilis
- Twins Strider and Azure, born in 2021
- Daughter Arcadia, born in 2024
- Son Seldon Lycurgus, born in 2025
There have been reports suggesting that Musk might have another child with Ashley St. Clair, a conservative author and influencer, though this has not been publicly confirmed.
Musk’s Views on Population Growth
Musk has repeatedly spoken about his concerns regarding declining birth rates, calling it one of the biggest threats to human civilization. In past interviews, he stated:
“If people don’t have more children, civilization is going to crumble. Mark my words.”
His belief in procreation as a solution to global population decline has seemingly influenced his personal life.
Musk and Zilis’ Professional Relationship
Shivon Zilis, an AI and technology expert, has worked closely with Musk for years. She is a Neuralink executive and was previously a top official at OpenAI, the AI research company Musk co-founded. Their relationship became public in 2022 after the birth of their twins, but details about their romantic involvement remain private.
What’s Next?
Neither Musk nor Zilis have shared further details about their newborn son, but given Musk’s public nature, more updates might emerge soon. Fans and critics alike continue to speculate about his growing family and his role as a father, entrepreneur, and global influencer.
