Both parents have publicly discussed the name’s meaning: ‘X’ for the unknown, ‘Æ’ for artificial intelligence, and ‘A-12’ as a reference to a precursor to the SR-71 Blackbird. X has appeared in limited social media posts by Grimes and has minimal public exposure compared to his siblings.
Name Elements Explained

Gavin Wilson Musk and Saxon Wilson Musk: Twins Born via IVF
Gavin and Saxon Wilson Musk, born in 2004, are fraternal twins from Elon Musk’s marriage to Justine Wilson. Their names were confirmed through court documents related to custody matters. Both were born via in vitro fertilization (IVF), a detail shared by Wilson in interviews discussing the challenges of conception and multiple births. They are the only set of twins among Musk’s confirmed children.
Kai Musk: The Youngest Son from the Justine Wilson Relationship
Kai Musk, born in 2006, is the youngest son of Elon Musk and Justine Wilson. He is the only son from that marriage not part of a twin set. His name became publicly known via custody and family-law filings in California. As of the latest widely available records, Kai maintains very low public visibility and is not frequently featured in media.
Other Children and Surrogacy References
Musk has alluded to additional children outside of the five above, potentially via surrogacy, but specifics about names, birth years, or current details have not been publicly verified. Statements mentioning children with surrogates appear in legal or interview contexts without further identification. As such, these references remain unconfirmed and are not included in the core verified profile.
Relationship Context and Family Background
Musk’s children span relationships with two primary partners: Justine Wilson (m. 2000–2008) and Grimes (partnered from roughly 2018 to 2021, with a child born in 2020). He has primary custody of his children with Wilson, while arrangements involving his child with Grimes have been subject to public and legal discussions. Understanding these relationships clarifies which children are biologically confirmed, which are named in reliable records, and which remain speculative.
