The Untold Stories: A Deep Dive Into Elon Musk's Four Daughters And Their Latest 2025 Updates
Elon Musk’s family life has become as much a topic of global discussion as his ventures into space exploration and electric vehicles. With reports confirming he is a father to 14 children across four mothers as of early 2025, the spotlight often falls on the unique circumstances and lives of his offspring. This article provides a comprehensive and up-to-date look into the lives of the four daughters of the tech mogul, focusing on the latest, most current information available in late 2025, from their unique names to their public statements.

Vivian Jenna Wilson: The Estrangement and Public Life in 2025
The most public and widely discussed of Elon Musk’s daughters is Vivian Jenna Wilson. Born Xavier Musk, she is the eldest of the five surviving children from Musk's first marriage to author Justine Wilson. Her story gained international attention in 2022 when she filed a petition in Los Angeles to legally change her name and gender identity, stating clearly that she wished to be recognized as female and wanted to sever all ties with her biological father.
The relationship between Vivian and her father has remained strained, with recent updates in 2025 bringing it back into the media spotlight.
The "Woke Mind Virus" Controversy
In 2025, Vivian's relationship with her father was further scrutinized following his continued public commentary on "woke mind virus" and gender identity issues. Vivian, now 21, has used her social media platform to subtly push back against her father's views, even adopting one of his public criticisms as part of her profile bio in a move widely interpreted as a direct "clapping back" at the tech billionaire. This public friction highlights the deep personal and ideological gulf between the father and daughter.
Vivian’s decision to change her surname to Wilson, her mother Justine Wilson's maiden name, was a clear statement of her desire for independence and a life separate from the Musk name. Her public life, including an August 2025 appearance on a drag performer's show, has positioned her as a figure in the social media and LGBTQ+ community, directly contrasting with her father’s political and social commentary.
The Unique Naming Conventions: Exa Dark Sideræl Musk ("Y") and Azure Zilis
While Vivian’s story is one of personal struggle and public estrangement, the other daughters share a common thread of highly unique, almost science-fiction-inspired names, a signature of their father's unconventional approach to life.
Exa Dark Sideræl Musk: The Child of Grimes
Born via surrogate in December 2021, Exa Dark Sideræl Musk, often called "Y," is the second child of Elon Musk and Canadian artist Grimes (Claire Boucher). Her name is an amalgamation of complex, esoteric concepts:
- Exa: A reference to the supercomputing term exaFLOPS, representing a billion billion floating-point operations per second.
- Dark: A nod to Dark Matter, the mysterious, unseen component of the universe.
- Sideræl: Pronounced 'sigh-deer-ee-el', a more "elven" spelling of sidereal, meaning "of the stars."
Exa Dark Sideræl and her older brother, X Æ A-Xii ("X"), and her younger brother, Techno Mechanicus ("Tau"), form a trio of children with Grimes, each name reflecting a fusion of technology, science, and fantasy. Despite the public attention on their names, the lives of these children remain largely private, with Grimes offering occasional, carefully curated updates.
The Shivon Zilis Daughters: Azure and Arcadia
The family of Elon Musk and Neuralink executive Shivon Zilis has been a source of significant recent news. The pair welcomed boy-girl twins in November 2021, just weeks before Exa Dark Sideræl's birth. The daughter of this twin set is named Azure Zilis, twin to her brother Strider Zilis.
Further updates in 2025 revealed that Musk and Zilis have more children than initially known, bringing their total to four. This includes a daughter named Arcadia Zilis, whose name and gender were previously unconfirmed by public sources. The full list of their children—Strider, Azure, Arcadia, and the newborn son Seldon Lycurgus—was confirmed in early 2025. The revelation of Arcadia as a daughter is a fresh detail, confirming a third daughter for the tech mogul.
The Legacy of a Growing Family and the Future
With 14 children as of late 2024, Elon Musk’s growing family is a testament to his public belief that smart people should have more children to combat population decline, a philosophy he often links to the future of civilization.
The lives of his four daughters—Vivian, Exa Dark Sideræl, Azure, and Arcadia—represent different facets of his complex personal world. Vivian's public life and estrangement from her father represent a poignant, human story of ideological conflict in the digital age. Meanwhile, the younger daughters, with their highly private lives and futuristic names, are growing up under the shadow of a father whose ambitions span the globe and the stars.
As the children grow older, the public will undoubtedly continue to watch how they navigate their extraordinary lineage. The entities surrounding Musk—including Tesla, SpaceX, Neuralink, and The Boring Company—form a vast empire that will inevitably shape the lives and eventual legacies of all his children, including his four daughters, for decades to come.
