Elon Musk and Shivon Zilis have confirmed the end of their relationship after more than five years together, during which they welcomed four children via in vitro fertilization.
Key facts
Shivon Zilis publicly announced the breakup on October 2, 2026, via X.
The couple has four children: twins Strider and Azure (born in 2021), daughter Arcadia (born in 2024), and son Seldon Lycurgus (born in February 2025).
Zilis shared a screenshot of a text exchange with Musk from a week before their breakup, where they exchanged "I love you" messages.
She expressed her desire to remain friends and co-parents after their split.
Why it matters: The breakup provides a rare look into one of Musk's more private relationships, which was largely kept out of the public eye, contrasting with some of his past high-profile romances.
Zilis has been a key figure in Musk's ventures, serving as director of operations at Neuralink, which adds complexity to their personal and professional relationship.
Their split could impact Musk's inner circle, especially since Zilis is the mother of four of his children and closely tied to his business empire.
Musk has a total of 14 children with four different women, making this breakup part of a larger narrative surrounding his family dynamics.
Driving the news: Zilis took to X to make the announcement after Musk unfollowed her on the platform, an act that appears to have prompted her public statement.
In her post, she stated, "It's hard to go from in love to let go in a week with no warning, but that's just how it is sometimes."
Zilis described her feelings of loss and expressed gratitude for their children, stating, "I’ve loved him more than life itself and he’s taught me 100 lifetimes of knowledge."
She emphasized the importance of their shared experiences, saying, "I feel happy that I got to show Elon how it feels to be deeply understood, nurtured, and peacefully loved with stability and gentleness."
The big picture: The relationship between Musk and Zilis has always been unconventional, starting with a brief romantic encounter in 2016 that evolved into co-parenting.
They welcomed twins Strider and Azure in November 2021, followed by Arcadia in February 2024 and Seldon in February 2025.
Zilis has worked closely with Musk's companies, including Neuralink and OpenAI, highlighting the blend of their personal and professional lives.
Their relationship dynamics have drawn attention, particularly after court documents revealed their family ties during Musk's legal disputes.
What they're saying: Zilis' emotional post included a heartfelt message to Musk, wishing him well and expressing her hope for a continued friendship.
