Elon Musk’s Children: Meet His 11 'Musketeers' Arranged by Birth Date

by Kristine Bowman


Elon Musk, the innovative mind behind Tesla, isn’t just a tech luminary; he’s also a remarkable father, proudly embracing fatherhood with 11 children stemming from his adventurous journey through love and life. Known for his concerns about global population trends, he’s wasted no time in expanding his family.

Over the span of two decades, this billionaire entrepreneur, renowned for his multiple romantic liaisons, has introduced us to an impressive array of mini-Musks. From his first child born in 2002 to the latest sensation, Techno Mechanicus, emerging from the pages of Walter Isaacson’s biography, Elon’s fatherhood journey has been nothing short of fascinating.

Affectionately dubbed ‘Tau’, this mysterious addition remained concealed until the unveiling of Walter Isaacson’s biography about Elon Musk, shedding light on Grimes as the mother of three of Musk’s children. This revelation was startling, considering the world was only aware of 10 of Elon Musk’s offspring.

As curiosity peaks regarding Elon Musk’s children, his varied romances, and family dynamics, we take you on a journey to explore Elon’s remarkable progeny and the extraordinary women who have played integral roles in shaping this visionary father’s legacy.

Meet Musk’s 11 children in chronological order

Starting with a glimpse into the lives of their mothers:

Justine Wilson:

His inaugural partner Justine Wilson, a Canadian author, was Elon’s first wife and the pioneering companion in his journey into parenthood. Their marriage, spanning from 2000 to 2008, blessed Musk with his first six children. Wilson playfully referred to herself as a ‘starter wife’ in a candid Marie Claire essay.


His musical muse Grimes, the Canadian singer and songwriter, shares three children with Elon Musk from their intermittent romantic entanglement. Their offspring includes X Æ A-Xii born in May 2020, followed by Exa Dark Sideræl and the latest addition, Techno Mechanicus (Tau), marking the newest chapter in their extraordinary family saga.

Shivon Zilis:

His Neuralink connection Elon’s personal and professional worlds intersected when he welcomed twins with Shivon Zilis, a top executive at Neuralink, in November 2021, amidst his complex relationship with Grimes.

But that’s not the whole story.

In the midst of these relationships, the Tesla CEO also entered matrimony twice with actress Talulah Riley—first from 2010 to 2012, and then from 2013 to 2016. However, they did not have children together (unless there’s another biography in the works that proves otherwise).

Now, let’s delve into Elon Musk’s 11 children:

Nevada Alexander (deceased at 10 weeks)

Born in 2002 to Elon Musk and Justine Wilson, Nevada’s life tragically ended at just 10 weeks due to sudden infant death syndrome (SIDS).

Griffin Musk – 19 years old

Following the loss of their first child, Elon and Justine turned to IVF, leading to the joyous arrival of twins Griffin and Vivian in April 2004. Griffin, now 19, stands as Musk’s eldest son.

Vivian Jenna Wilson – 19 years old

Vivian, Elon Musk’s daughter, born alongside her twin brother Griffin in 2004, embarked on her own journey of self-discovery. At 18, she initiated legal proceedings to change her name and gender, seeking acknowledgment of her identity as a woman and distancing herself from her father’s name.

Kai, Saxon, and Damian Musk – 17 years old

Expanding their family further, Elon and Justine welcomed triplets Kai, Saxon, and Damian in January 2006 through IVF. Now 17, these three sons mark yet another chapter in Musk’s cosmic family saga.

X Æ A-Xii – 3 years old

Elon Musk and Grimes welcomed their first child together on May 4, 2020. Initially named X Æ A-12, their son’s name was later modified to X Æ A-Xii, reflecting their distinctive parental flair.

Azure and Strider – 1 year old

During Musk’s intermittent relationship with Grimes, he also shared a brief romance with Neuralink’s Director of Operations and Special Projects, Shivon Zilis. Their union brought twin sons Azure and Strider into the world in November 2021, coinciding with Grimes welcoming a daughter via surrogate.

Exa Dark Sideræl Musk – 1 year old

Just a month after welcoming twins with Shivon Zilis, Musk and Grimes celebrated the arrival of their daughter, Exa Dark Sideræl Musk, born via surrogate in December 2021.

Techno Mechanicus (Tau)

The latest addition to Elon’s cosmic crew, Techno Mechanicus—fondly known as Tau—was revealed to the world through Walter Isaacson’s biography, marking Elon’s 11th child.

Considering Elon Musk’s outspoken views on underpopulation, it wouldn’t be surprising to witness a few more additions to his extraordinary brood in the future.
