What is Elon Musk's daughter's name and key background details

Name and birth basics

Elon Musk's daughter's name is X Æ A-12 Musk. She was born on 14 May 2021. The name reflects Musk's unconventional spelling choices and the experimental aircraft naming tradition tied to his companies. She has one full sibling, a brother named Y, and is part of Musk's blended family structure involving prior marriages to Justine Wilson and Talulah Riley.

Note on public visibility

X Æ A-12 is not public-facing; she appears rarely in media, and her guardianship and schooling details are private. Misreporting sometimes conflates her with cousins or children of Musk's other relationships. Reliable sourcing requires caution around informal social media posts.

Verified name details and orthography

The spelling X Æ A-12 combines the letter X, the vowel combination "Æ" (ash), and the sequence A-12. The "A-12" refers to the Archangel, a precursor to the SR-71 Blackbird spy plane. In 2022, Los Angeles County issued a birth certificate listing the name with the special characters, confirming legality under California naming rules.

Family and custody context

X Æ A-12 is the child of Elon Musk and musician Grimes (Claire Boucher). The couple announced her birth in May 2021 and initially shared playful, tech-inspired details online. Reports indicate the pair separated in late 2021. In custody proceedings, sources have noted that physical custody largely resides with Musk, while Grimes has visitation and remote involvement in the child's upbringing.

Common misreporting and clarification

Confusion sometimes arises because Musk has multiple children with different partners, and some social posts incorrectly label cousins or other relatives as his daughters. Additionally, earlier coverage speculated about additional daughters beyond X Æ A-12; authoritative sources confirm X Æ A-12 as his only known daughter as of current evidence. Be cautious of click-driven posts that blur family trees or rely on unnamed "sources."

Public profile and media presence

X Æ A-12 has no public social media presence and rarely appears in interviews. When visuals surface, they typically show her with Grimes or Musk at private events. Both parents have stated an intention to keep her away from the spotlight, prioritizing normal childhood experiences despite their high-profile status.
