Elon Musk, the 52-year-old Tesla founder and tech mogul, quietly welcomed a new addition to his expanding family earlier this year. The mother of the baby is Shivon Zilis, director of special projects at Neuralink Corp., another company founded by Musk. Musk and his partners have consistently maintained a private family life, shielding their children from public scrutiny.

This commitment to privacy was underscored in September 2023 when Claire Boucher, known as Grimes and mother to three of Musk’s children, appealed for privacy regarding her co-parenting relationship with Musk and the recent revelation of their third child, a son named Techno Mechanicus. Techno Mechanicus was born shortly after Musk’s children with Zilis.

Elon Musk’s journey into fatherhood began in 2002 with the birth of his first son, Nevada Alexander, with his first wife, Justine Wilson. Tragically, Nevada passed away at 10 weeks old due to sudden infant death syndrome (SIDS). Wilson and Musk later had twins, Vivian Jenna and Griffin, in 2004, followed by triplets Kai, Saxon, and Damian in 2006, all conceived through IVF.

In May 2020, Musk and Grimes welcomed their first child together, a son named X Æ A-Xii. Later, in December 2021, they had a daughter via surrogate named Exa Dark Sideræl. Around the same time, Musk welcomed twins, Strider and Azure, with Shivon Zilis in November 2021. The disclosure of Musk’s newest child coincides with journalist Walter Isaacson’s 2023 biography about Musk, which revealed the birth of Musk and Grimes’ third child, Techno Mechanicus, also known as “Tau.”

Regarding the birth of his latest child with Shivon Zilis, Musk clarified, “As for ‘secretly fathered,’ that is false. All our friends and family know. Not issuing a press release, which would be odd, does not equate to ‘secret.’” Despite this clarification, Musk and Zilis have chosen to keep the sex and name of their youngest child undisclosed, emphasizing their dedication to maintaining privacy.

Elon Musk’s personal life has long been a subject of intense public interest and scrutiny, owing to his high-profile relationships and significant professional accomplishments. The increasing number of his children and the dynamics among his partners illuminate the complexities of his personal life, frequently played out under the public gaze.
