An Advocate and Model

Vivian has embraced her role as a transgender advocate, using her platform to raise awareness and speak out on issues important to the LGBTQ+ community.

She has also pursued a career in modeling and is considered a social media personality, leveraging her visibility to connect with a global audience. Her public statements, including her criticism of her father’s political gestures, demonstrate a willingness to engage in current affairs and use her voice.

Clarifying the $40 Billion Rumor

One persistent rumor surrounding Vivian is the claim that she has access to a massive $40 billion trust fund from her father. Vivian has publicly addressed and refuted this claim, clarifying that she does not have access to a trust fund of that magnitude and that her finances are separate from her father's immense wealth.

Her current earnings are reportedly derived from her work as a model and her social media ventures, with estimated net worth figures in the lower millions.

The Complete Family Tree: Vivian's Place Among 14 Children

To fully understand Vivian's position, it is essential to place her within the context of the ever-expanding Musk family. Elon Musk is a father to a total of 14 children with four different women, a number that continues to grow with recent additions in 2024.

The Twins and Triplets

Vivian and her twin brother, Griffin Musk, were born in 2004 via in vitro fertilization (IVF) to Elon and Justine Musk. They are the oldest surviving children.

Following them, Justine and Elon welcomed triplets Kai, Saxon, and Damian Musk in 2006, also via IVF. Tragically, Elon Musk’s first child, a son named Nevada Alexander Musk, died of Sudden Infant Death Syndrome (SIDS) at just 10 weeks old in 2002.

The Younger Half-Siblings (LSI Entities)

Vivian's half-siblings include the children from Elon Musk’s relationships with musician Grimes and Neuralink executive Shivon Zilis, as well as a more recent child with conservative influencer Ashley St. Clair.

The list of her younger half-siblings, which provides crucial topical authority, includes:

• X Æ A-Xii (X) (with Grimes)
• Exa Dark Sideræl Musk (Y) (with Grimes)
• Techno Mechanicus (Tau) (with Grimes)
• Arcadia (with Shivon Zilis)
• Seldon Lycurgus (with Shivon Zilis)
• Romulus (with Ashley St. Clair)
