Elon Musk’s 14 children and their mothers have become the subject of growing public curiosity. The tech titan and multi-company CEO has built a sprawling, unconventional family with four women — each with a unique connection to his life. From a fantasy author to a pop star, a Neuralink executive to a political commentator, Musk’s children come from a wide range of maternal backgrounds.

Here’s a detailed breakdown of his ever-expanding family tree — with every mother and child named.

👩‍🍼 Justine Wilson

Children: 6 (1 deceased)
Relationship: Married 2000–2008

Elon Musk’s first marriage was to Justine Wilson, a Canadian author he met while attending Queen’s University. They married in 2000 and had six children, all conceived via IVF.

• Nevada Alexander Musk (b. 2002) was their first child but tragically passed away at 10 weeks old due to SIDS.
• In 2004, they had twins: Vivian Jenna Wilson (who changed her name and gender identity) and Griffin Musk.
• In 2006, they welcomed triplets: Kai, Saxon, and Damian Musk.

The couple divorced in 2008. Justine continues to write and co-parents her children privately.

🎤 Grimes (Claire Boucher)

Children: 3
Relationship: Dated 2018–2021 (on and off afterward)

Musk began dating Canadian musician Grimes in 2018. Their relationship, filled with cryptic tweets and surreal baby names, made headlines worldwide.

• X Æ A-12 Musk, born in 2020, was later renamed X Æ A-Xii to comply with California law.
• Their daughter, Exa Dark Sideræl Musk, nicknamed “Y“, was born via surrogate in December 2021.
• A third child, Techno Mechanicus, nicknamed “Tau“, was born around 2023 via surrogate, as revealed in Walter Isaacson’s biography of Musk.

Despite their split, the pair reportedly co-parent with shared custody and ongoing tension over logistics and parenting styles.

🧠 Shivon Zilis

Children: 4
Relationship: Never publicly romantic; professional

Shivon Zilis is a top executive at Neuralink and one of the most private women in Musk’s life. While the two have never publicly acknowledged a romantic relationship, she has had four children with Musk via IVF.

• In November 2021, she gave birth to twins: Strider Sekhar Sirius and Azure Astra Alice.
• In February 2024, she welcomed a daughter named Arcadia.
• On February 28, 2025, her fourth child with Musk, a son named Seldon Lycurgus, was born — names that reflect Musk’s obsession with sci-fi and classical philosophy.

Zilis is known for her intellect, discretion, and strong presence in AI and neuroscience spaces.

🗞️ Ashley St. Clair

Children: 1 (alleged)
Relationship: Disputed

Ashley St. Clair, a conservative commentator and political influencer, alleged in 2024 that Elon Musk is the father of her son, born in September 2024.

• Musk has not confirmed paternity, stating in early 2025 that he was “uncertain” and providing financial support while awaiting legal confirmation.
• St. Clair filed for child support and legal paternity recognition.

If confirmed, this would be Musk’s 14th child, and the first resulting in a public legal dispute.

🧬 Elon Musk’s Population Philosophy

Musk has frequently tweeted about his concern for declining global birthrates, framing his growing family as part of a mission to help “secure the future of humanity.” He’s gone as far as saying, “A collapsing birth rate is the biggest danger civilization faces.”

His family tree now reflects that belief — with names straight out of science fiction novels and co-parenting arrangements as unconventional as his companies.
