Everything You Want To Know About Elon Musk’s 12 Children & 3 Partners

Elon Musk, the trailblazing entrepreneur who redefined industries with Tesla, SpaceX, and Neuralink, is as much a figure of fascination in his personal life as he is in his professional endeavors. Beyond his technological triumphs, Musk is a father to 12 children, born to three distinct and accomplished women over the past two decades. His family saga is a tapestry of love, loss, and an unrelenting drive to expand his lineage—perhaps a reflection of his outspoken concerns about global population decline. As of March 21, 2025, Musk’s brood and the dynamics with his partners offer a captivating glimpse into the life of one of the world’s most enigmatic billionaires. Here’s everything you need to know about his 12 children and the three women who share this journey with him.

Justine Wilson: The Foundation of Musk’s Family

Musk’s foray into fatherhood began with Justine Wilson, a Canadian author whose intellectual spark first caught his eye at Queen’s University in Ontario during the 1990s. The pair married in 2000, embarking on a partnership that would produce six children, though marked by profound tragedy and eventual separation.

Their first son, Nevada Alexander Musk, arrived in 2002 but tragically passed away at 10 weeks old due to Sudden Infant Death Syndrome (SIDS). The loss left an indelible mark on Musk and Wilson, with Justine later chronicling the grief in a 2010 Marie Claire piece. Undeterred, they turned to in vitro fertilization (IVF) to grow their family. In 2004, twins Griffin Musk and Vivian Jenna Musk (born Xavier Alexander Musk) were born. Vivian, who transitioned and adopted her new name in 2022, has since publicly distanced herself from Musk, citing ideological rifts—a rare glimpse of tension within the family.

Two years later, in 2006, triplets Kai, Saxon, and Damian Musk joined the fold, also via IVF. These five surviving children—now young adults—represent Musk’s earliest legacy as a father. His marriage to Wilson, however, unraveled by 2008 amid personal and professional strains. Post-divorce, they’ve co-parented their brood, with the children balancing time between Musk’s high-octane world and Wilson’s more grounded literary life. Justine’s role as Musk’s first partner laid the groundwork for his expansive family vision.

Grimes: A Galactic Love Story

Enter Claire Boucher, known to the world as Grimes, the avant-garde musician whose relationship with Musk began in 2018 after a Twitter exchange about artificial intelligence. Their union—equal parts cosmic and chaotic—has produced three children, each bearing names that defy convention and reflect their shared eccentricity.

Their first child, X Æ A-Xii Musk (nicknamed “X”), arrived in May 2020. The name, a puzzle of symbols and references, stirred global intrigue. Grimes explained it as a tribute to the Archangel 12 aircraft and AI, while Musk quipped it sounded like a password gone wrong. After legal pushback from California authorities, they settled on X Æ A-Xii. In December 2021, via surrogate, they welcomed Exa Dark Sideræl Musk, or “Y,” a name steeped in sci-fi lore—Exa for computing power, Dark for cosmic unknowns, and Sideræl for a Tolkien-esque flourish. Her birth was a quiet affair, only revealed when a reporter stumbled upon the sound of a baby during a Grimes interview.

Their third child, Techno Mechanicus Musk (nicknamed “Tau”), was born in 2022, with details emerging later via a 2023 biography review by Grimes. The name nods to Musk’s tech obsession, blending machinery and innovation. Though their three children bind them, Musk and Grimes’ romance has been a rollercoaster. By 2022, Grimes described their bond as “fluid” in Vanity Fair, and by 2023, legal filings over parental rights hinted at strain, with Grimes seeking access to one of their children amid reported disputes.

Grimes’ partnership with Musk is a fusion of art and futurism, producing a trio of kids as unconventional as their parents. Despite the ups and downs, their shared creativity continues to shape their family narrative.

Shivon Zilis: The Discreet Tech Ally

The third woman in Musk’s family constellation is Shivon Zilis, a behind-the-scenes powerhouse at Neuralink, Musk’s brain-computer interface venture. Unlike the public flair of his relationships with Wilson and Grimes, Musk’s connection with Zilis is quieter, rooted in professional synergy and mutual ambition.

In November 2021, Zilis gave birth to twins Azure Musk and Strider Musk, their arrival timed intriguingly close to Exa’s birth with Grimes. Azure, evoking a vivid sky, and Strider, suggesting a purposeful stride, carry Musk’s signature naming flair. Court documents later showed Musk and Zilis aligning their twins’ surnames to reflect both parents, hinting at a collaborative bond. Zilis, a Yale-educated Canadian who joined Neuralink in 2017, brings a sharp intellect to the table, making her an ideal partner in Musk’s orbit.

Whispers in 2024 suggested a possible third child with Zilis, though Musk’s penchant for privacy keeps such claims unconfirmed. Their relationship, less romantic than functional, mirrors Musk’s knack for blending personal and professional realms—Zilis’ role at Neuralink and her motherhood intertwining seamlessly with his vision.

The Musk Brood: 12 Kids and Counting

As of March 2025, Musk’s 12 known children are a testament to his prolific family-building ethos. With Justine Wilson, he has five: Griffin, Vivian, Kai, Saxon, and Damian. With Grimes, three: X, Exa, and Techno. With Shivon Zilis, two confirmed: Azure and Strider, with potential others still shrouded in mystery. Nevada’s brief life remains a somber memory, excluded from the current count.

Musk’s children span a wide age range, from young adults to toddlers, each bearing names that echo his futuristic mindset. The older ones, like Griffin and the triplets, have been shaped by Musk’s experimental Ad Astra school and his boundless resources, while the younger ones, like X and Exa, often pop up alongside him at SpaceX launches or Tesla events, hinting at his hands-on parenting style despite his packed schedule.

A $35 Million Vision and a Population Crusade

Musk’s family ambitions extend beyond numbers. In 2024, he reportedly snapped up a $35 million compound in Austin, Texas, envisioning it as a central hub for his children and their mothers. The estate, with multiple residences and vast grounds, reflects his dream of a unified clan—though logistical and personal challenges, including Grimes’ hesitations, suggest it’s a work in progress.

His drive to procreate ties into a broader ideology. Musk has long warned of a “population collapse,” urging others to have more kids while leading by example. This stance, aired in interviews and on X, has sparked both admiration and critique—some see it as a noble cause, others as a billionaire’s quirk. Regardless, it’s a thread that runs through his family story.

The Partners: Three Women, One Legacy

Justine Wilson, Grimes, and Shivon Zilis each bring a distinct flavor to Musk’s world. Wilson, the literary soulmate turned co-parent, gave him stability in his early years. Grimes, the ethereal artist, infused his life with cosmic flair and unpredictability. Zilis, the tech strategist, offers a grounded yet innovative partnership. Together, they’ve helped Musk craft a legacy that’s as much about human connection as it is about technological conquest.

What Lies Ahead?

Elon Musk’s family is a living paradox—intimate yet expansive, private yet scrutinized. As of March 21, 2025, his 12 children and three partners paint a picture of a man who defies norms at every turn. Whether he’s launching rockets or cradling a newborn, Musk’s dual pursuit of innovation and lineage keeps the world watching. Will his Austin compound become the family utopia he envisions? Will more children join the fold? Only time will tell, but one thing is certain: Musk’s clan is as extraordinary as the mind behind it.
