Shivon Zilis, director of operations and special projects at Neuralink, revealed that Elon Musk abruptly ended their five-year romantic relationship without prior warning. The public disclosure followed online attention across X after automated tracking accounts noticed that the 55-year-old billionaire had stopped following her profile on the social network he owns.

Zilis, 40, stated on Friday (2) that their private partnership unravelled in the span of seven days, despite recent affectionate exchanges. “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 wrote, confirming that she shares four children with Musk, all conceived through in vitro fertilisation.

Shivon Zilis publishes text messages from Elon Musk

The announcement arrived after users began discussing Musk’s decision to unfollow her account on Friday morning. In response, Zilis posted a statement addressing the split alongside a screenshot of a private text exchange from Thursday, September 24, 2026. In the messages, contact “E” sent affectionate notes about breakfast and addressed an official diplomatic event involving Chinese President Xi Jinping. Musk wrote that he did not know the state dinner allowed a partner to attend, telling her: “I didn’t realize that this Xi dinner included a significant other, or I would have invited you.”

The exchange took place just days before tensions surfaced publicly. On Sunday, September 27, 2026, Zilis had posted a brief message on X stating “New day, new life,” which observers later linked to the sudden shift in their domestic arrangement. Zilis explained that she wanted to address the unfollow directly to provide clarity to those monitoring the situation online.

“I feel happy that I got to show Elon how it feels to be deeply understood, nurtured, and peacefully loved with stability and gentleness,” Zilis wrote in her post. “I loved being that counterbalancing place of safety, sense of calm, and love — and delighted in bringing a smile back to his face when he was down. I will miss him dearly.”

Court testimony detailed how the relationship began

Details surrounding the personal dynamic between Musk and Zilis first became part of the public record earlier this year during legal proceedings between Musk and OpenAI co-founder Sam Altman. Testifying in court in May 2026, Zilis explained that Musk originally agreed to be a sperm donor when she decided to establish a family as an independent mother. Over time, that arrangement evolved into a domestic partnership lasting approximately five years, during which biographer Walter Isaacson described her in his book about Musk as an intellectual companion who frequently discussed strategic concepts and artificial intelligence systems with the entrepreneur.

With the four children born to Zilis, Musk is known to have fathered 14 children across relationships with four women. Zilis emphasised in her statement on Friday that her primary focus remains the welfare of their young family, expressing hope that both parents will maintain a collaborative environment despite the abrupt romantic conclusion. “I’m hurting, but care deeply about E and will always be cheering for his happiness,” she wrote, adding: “I do hope and pray he and I can be great friends and coparents.”

Absence of public comment from Elon Musk

Musk has not publicly commented on the end of the relationship, nor has he offered an explanation regarding the decision to unfollow Zilis on X. Representatives for Neuralink, where Zilis continues to hold her executive position overseeing operations and special initiatives, did not respond immediately to requests for comment on Friday afternoon.
