Shivon Zilis, a graduate from Yale with a specialisation in machine learning and artificial intelligence, crossed paths with Musk when she joined OpenAI, a startup he co-founded in 2016. She currently serves as the director of special projects at Neuralink. Zilis holds Musk in high regard, publicly expressing her admiration for him and his work. When Musk proposed the idea of having children together via in vitro fertilization, highlighting his belief in the importance of intelligent individuals having offspring, Zilis was in agreement.
In a candid account shared with Walter Isaacson for his 2023 biography of Musk, Zilis revealed that the decision to have children with Musk was an easy one due to her deep respect and admiration for him. Musk, who has a total of 10 other children from previous relationships, was enthusiastic about expanding their family. The couple relocated to Austin, Texas, where they welcomed their twins via IVF in November 2021. Subsequently, they had two more children together – daughter Arcadia in February 2024, and son Seldon Lycurgus.
The twins, Strider and Azure, were born just ahead of Musk welcoming his second child with Grimes in December 2021. The twins’ existence was initially undisclosed, with Musk and Zilis later requesting to change their names to include their mother’s last name as their middle name, which was granted by a judge. The full names of the twins, Strider Sekhar Sirius and Azure Astra Alice, along with their first photo, were unveiled in a TIME article in September 2023.
Zilis has shared glimpses of her children on social media platforms, showcasing moments with the twins visiting their father at SpaceX, Musk’s space technology company. In a heartfelt tribute, she publicly acknowledged her daughter Arcadia’s birth and later shared about the arrival of their son Seldon Lycurgus in February 2025. The family’s journey has been chronicled through Zilis’ social media accounts, offering followers a peek into their lives and milestones.
The partnership between Musk and Zilis not only highlights their professional success but also celebrates their journey into parenthood. As they navigate the challenges and joys of raising four children in the public eye, their story continues to captivate and inspire many. With each addition to their family, Elon Musk and Shivon Zilis embark on a new chapter filled with love, growth, and shared aspirations.
As the world looks on, this power couple’s journey as parents and innovators underscores their commitment to shaping a brighter future both at home and in their respective fields. The legacy they are creating together through their children and groundbreaking work serves as a testament to their shared values and vision for the world.
