Elon Musk, the renowned CEO of Tesla and SpaceX, is widely reported to be a father of 12 children, born from 3 different relationships. His family includes six children with his first wife, Justine Wilson; three with ex-girlfriend Grimes and three with Shivon Zilis, an executive at his neurotechnology company Neuralink. Author Ashley St. Clair claims that she is also mother to Musk’s one kid.
Here’s a closer look at the billionaire entrepreneur’s children and the women in his life:
Nevada Alexander Musk
Elon Musk and Canadian author Justine Wilson were married in January 2000. In 2002, they welcomed their first child, Nevada Alexander Musk. Tragically, Nevada died from sudden infant death syndrome (SIDS) at just 10 weeks old.
Griffin Musk and Vivian Musk
Following the loss of their firstborn, Musk and Wilson turned to IVF to grow their family. In April 2004, they welcomed twins Griffin and Vivian Musk, who are now 20 years old. Vivian Wilson is the trans daughter of Musk, who said, “I lost my son, essentially,” using Wilson’s birth name. Musk said that she was “dead, killed by the woke mind virus.”
Kai, Saxon, and Damian Musk
Through IVF, Musk and Wilson had triplet sons, Kai, Saxon, and Damian, in 2006. Now 19 years old, the triplets largely remain out of the public eye. Musk and Wilson divorced in 2008.
X AE A-XII Musk
Musk began dating singer Grimes in 2018. Their son, X AE A-XII, was born in May 2020. His unusual name was slightly modified due to California law, which restricts the use of certain characters. Musk and Grimes separated in September 2021 and have been involved in a public custody battle.
Exa Dark Siderael Musk
In March 2022, Grimes revealed in a Vanity Fair interview that she and Musk had welcomed a daughter, Exa Dark Siderael Musk, via surrogate in December 2021. Exa, nicknamed Y, is now three years old. Although Grimes initially referred to Musk as her “boyfriend” in the interview, she later clarified on Twitter that they had broken up.
Strider and Azure
In November 2021, Musk had twins with Shivon Zilis, a director at Neuralink. The twins are now two years old. Initially, the couple filed a petition to change the twins’ names to include both parents’ last names. The names, Strider and Azure, were revealed in September 2023.
Techno Mechanicus
According to Walter Isaacson’s biography, “Elon Musk,” published in September 2023, Musk and Grimes welcomed a third child together in June 2022. Named Techno Mechanicus and nicknamed “Tau,” the child has remained largely out of the public spotlight.
Unknown child born in early 2024
Musk has also confirmed the birth of his twelfth child, stating that their friends and family were aware of the birth. However, details about the child’s name and sex were not publicly released.
Unknown child reportedly born in late 2024
In February 2025, author Ashley St. Clair claimed in a statement on X (formerly Twitter) that she and Musk had a child together a few months prior.
