Musk’s journey into fatherhood began in 2002 with his first child, Nevada Alexander, whom he shared with his first wife, Justine Wilson. Unfortunately, Nevada passed away from sudden infant death syndrome (SIDS) at just 10 weeks old. However, Musk and Wilson had five more children together, including twins and triplets.

As his career took off, Musk’s family life evolved. After divorcing Wilson, Musk married actress Talulah Riley twice but did not have children with her. His relationship with musician Grimes, which began in 2018, brought three children into his life. Musk also fathered twins with Neuralink executive Shivon Zilis, expanding his growing family.

Here’s a breakdown of Elon Musk’s children and their mothers:

Nevada Alexander Musk

Nevada was Musk’s firstborn with his ex-wife, Justine Wilson, but tragically passed away at just 10 weeks old due to SIDS. The loss of Nevada left a profound impact on Musk and Wilson, both of whom have opened up about the grief they experienced following his death.

Vivian and Griffin are Musk’s twins, born to Justine Wilson in April 2004. Vivian made headlines in 2022 when she legally changed her name and gender, expressing her desire to sever ties with her father. Musk has commented on the situation, but Vivian has been vocal in her own public statements about her identity and relationship with him.

Kai, Saxon, and Damian Musk – The Triplets

In 2006, Musk and Wilson welcomed triplets Kai, Saxon, and Damian. The triplets, conceived via IVF, are relatively private individuals, though Damian has been noted for his musical talent and academic success. Musk’s mother, Maye Musk, even refers to Damian as “brighter than you” when speaking about his intelligence.

Musk and Grimes’s first child, X Æ A-12, made waves when his name was announced in 2020. The name, which was later changed to X Æ A-Xii, is a combination of the letter “X,” the character Æ (pronounced “ash”), and the A-12 plane, a reference to the CIA’s reconnaissance aircraft. Musk and Grimes have explained that the name combines their personal and technological interests.

Exa Dark Sideræl Musk

Exa Dark Sideræl Musk, affectionately called “Y,” was born in December 2021 via surrogate. Her name has special meaning to Grimes, with “Exa” referring to exaFLOPS, a computing term, and “Dark” symbolizing the unknown or dark matter. Her full name reflects Grimes’s love for science fiction and deep space.

While the twins were initially kept private, their birth details became public in 2023. Musk has commented light-heartedly about the “underpopulation crisis” and his growing family.

Techno Mechanicus (Tau)

In June 2022, Musk and Grimes welcomed a second son, Techno Mechanicus, known as “Tau.” Grimes has described him as having an old soul, joking that he looks like “a little Spock” and has an intense gaze. Grimes keeps details of Tau’s life private, focusing on protecting his privacy.

Arcadia Musk

In February 2024, Musk confirmed the arrival of his third child with Shivon Zilis, a daughter named Arcadia. Zilis shared a heartwarming post on her social media, wishing Arcadia a happy first birthday in February 2025. Musk has clarified that while his children’s births may not always be widely announced, they are not a secret.

However, she announced being hounded by the media, seeking to protect her child’s privacy.

Seldon Lycurgus Musk

Just after Arcadia’s first birthday, Zilis revealed the birth of another child with Musk, a son named Seldon Lycurgus, born in February 2025. The name carries a firm historical reference, as “Lycurgus” was a lawgiver from ancient Sparta. Zilis expressed how much she loves her son, describing him as “built like a juggernaut” and full of love.
