Musk’s journey into fatherhood began in the early 2000s with Canadian author Justine Wilson. The couple married in 2000 and soon welcomed their first son, Nevada Alexander Musk, in 2002. Tragically, Nevada passed away at just 10 weeks old due to sudden infant death syndrome—a loss Musk has rarely discussed publicly but which reportedly shaped his views on life and family.

Undeterred by tragedy, Musk and Wilson turned to IVF, welcoming twins Griffin and Vivian in 2004, followed by triplets Kai, Saxon, and Damian in 2006. Their marriage ended in 2008, but the legacy of their union endures. Vivian, who came out as transgender in 2022 and legally changed her surname, has been open about her strained relationship with Musk, adding complexity to the public’s understanding of the Musk family dynamic.

The Grimes Era: Art, Science, and Unusual Names

In 2018, Musk’s relationship with Canadian musician Claire Boucher, known as Grimes, brought a new chapter to his family saga. Their partnership, marked by intellectual curiosity and creative flair, produced three children: son X Æ A-Xii (born 2020), daughter Exa Dark Sideræl (born 2021 via surrogate), and son Techno Mechanicus (born 2022 via surrogate). The children’s unconventional names—blending references to artificial intelligence, science fiction, and mythology—reflect Musk’s unique worldview and penchant for challenging norms.

The Musk-Grimes relationship has been anything but ordinary. Public spats, custody disputes, and social media drama have regularly made headlines, yet Grimes has praised Musk’s commitment to fatherhood, describing him as “involved” despite his relentless work schedule. Their children, often seen at tech events and in viral photos, symbolize Musk’s fusion of technology and family life.

Neuralink and Beyond: The Shivon Zilis Connection

Musk’s family expanded further through his relationship with Shivon Zilis, a top executive at Neuralink. Zilis, known for her intelligence and privacy, has kept her personal life largely out of the spotlight. Together, she and Musk have four children: twins Strider and Azure (born 2021 via IVF), daughter Arcadia (born 2024 via surrogacy), and son Seldon Lycurgus (born late 2024 or early 2025). The birth of Seldon was announced by Zilis in February 2025, calling him “a juggernaut with a heart of gold.” Musk responded with a simple heart emoji, signaling his acknowledgment.

The secrecy surrounding their earlier children and the use of IVF and surrogacy highlight Musk’s pragmatic approach to family-building. Zilis’s low profile contrasts with the high drama of Musk’s other relationships, yet her role in the Musk dynasty is significant—especially given her position at Neuralink, a company focused on merging human brains with artificial intelligence.

The Latest Addition: Ashley St. Clair and a Custody Controversy

In September 2024, conservative influencer Ashley St. Clair publicly revealed that Musk was the father of her son, Romulus, after a paternity test confirmed a 99.9999% match. The announcement sparked immediate controversy, followed by a custody battle and claims of financial disputes. St. Clair alleged that Musk offered her millions to stay silent about their child—a claim Musk has neither confirmed nor denied.

Romulus’s birth, and the subsequent legal wrangling, have cast a spotlight on Musk’s complicated personal life. The public disclosure of their relationship and the custody fight have fueled tabloid speculation and raised questions about Musk’s relationships with the mothers of his children.

Pronatalism and Musk’s Mission

Beyond the headlines, Musk’s ever-growing family aligns with his outspoken views on population decline—a cause he has championed for years. Musk has repeatedly warned that “a collapsing birth rate is the biggest danger civilization faces,” urging people to have more children to ensure humanity’s survival. His own brood of fourteen—nine boys and five girls, ranging from infants to young adults—represents what he has called a “legion” to combat this crisis.

Musk’s use of IVF and surrogacy, and his willingness to form families with women from diverse backgrounds, reflect his belief in the importance of reproduction. He has argued that technology, wealth, and ambition should be used to build families as well as companies, and that his children could play a role in humanity’s future—perhaps even as pioneers on Mars.

Mars Needs People: Family as Cosmic Ambition

Musk’s vision for his family extends beyond Earth. As the founder of SpaceX, he has long advocated for the colonization of Mars, famously declaring, “Mars needs people.” Colleagues have hinted that Musk sees his children as potential participants in a multi-planetary civilization, blending his personal and professional ambitions in ways few other leaders have attempted.

This cosmic perspective adds a layer of idealism—and perhaps eccentricity—to Musk’s family-building. His children, raised in a world of innovation, technology, and risk-taking, may inherit not just his wealth but his vision for a future that transcends planetary boundaries.

Love, Loss, and Controversy: The Human Side of Musk’s Legacy

Despite his immense fortune—estimated at over $400 billion in 2025—Musk’s family life is marked by both love and controversy. The loss of his first son, Nevada, the estrangement from Vivian, and the public custody battles with Grimes and St. Clair reveal the challenges of managing such a sprawling family. Musk’s commitment to fatherhood, often described as hands-on and emotionally engaged, stands in contrast to the drama that surrounds him.

Critics argue that Musk’s approach is self-indulgent, a reflection of his larger-than-life persona. Supporters see him as a visionary, using his resources to address a global crisis and build a legacy that will endure for generations. The truth, as always with Musk, is likely somewhere in between.

The Future: Inheriting a Vision

As Musk’s “legion” grows, the world watches with curiosity—and skepticism. Can his children inherit not just his fortune but his drive, creativity, and cosmic ambition? Will they play a role in shaping humanity’s future, on Earth or beyond? And how will Musk balance fame, fatherhood, and the relentless pursuit of his dreams?

One thing is certain: Elon Musk’s family story is far from ordinary. It is a tapestry of love, loss, innovation, and controversy—a microcosm of the man himself. As he continues to build companies and families, Musk invites us to ponder deeper questions: What does it mean to leave a legacy? Can one person’s vision truly shape the destiny of humanity? And how does the future look when it is written not just in code and rockets, but in the lives of fourteen children?

Elon Musk’s growing legacy is more than a headline—it’s a living experiment in ambition, family, and the future of humanity. As the world’s most enigmatic billionaire continues to expand his brood, we are left to wonder: Is this the birth of a dynasty, or simply another chapter in the saga of a man who refuses to be ordinary?
