Siobhan Zilis: A key figure in Elon Musk's ecosystem and the mother of his twelfth child

Elon Musk for the first time publicly confirmed the birth of a new baby, who was born in early 2025. The child’s mother is Siobhan Zilis, who heads the ambitious Neuralink project, which is developing interfaces for implanting microchips in the human brain. Although the media space was filled with news about this event, Musk himself stressed in an interview with Page Six that the information was never intended to be hidden. “Everyone in our inner circle knows this,” he clarified, pointing out that public silence does not mean secrecy. The identity and sex of the newborn remain unknown to a wide audience.

Who is Siobhan Zilis: The path from OpenAI to Neuralink

Siobhan Zilis is an example of a professional who is deeply immersed in the field of artificial intelligence and advanced technology. Until 2023, she served on the board of directors of OpenAI, a non-profit organization dedicated to research in friendly and safe artificial intelligence. Notably, Musk co-founded OpenAI back in 2015, which set the stage for their joint interest in AI development. It was this shared passion for AI technology and security that likely formed the basis of their personal relationship. Zilis is now focused on the leadership of Neuralink, a company that works on revolutionary neurotechnology.

Musk’s family expands: the story of three children from Zilis

The third child of Siobhan Zilis and the Mask is a continuation of their journey together as parents. The story began in November 2021, when the couple had twins Strider and Azur. The news of this event remained confidential until July 2022, which clearly demonstrates the couple’s desire to maintain the privacy of their family life. Soon after the birth of the twins, a son named Techno was born, complementing Musk’s growing family. Thus, there are three children from Siobhan Zilis, significantly increasing the dynasty of the legendary entrepreneur.

Balance between openness and privacy in a large family

Simultaneously with the expansion of the family together with Zilis, Musk is developing a relationship with the singer Grimes, with whom he also has three children. In December 2021, just a month after the birth of twins Strider and Azur, Musk and Grimes welcomed daughter Exa Dark Siderael through surrogacy. Recently, Grimes published a detailed appeal on social networks, in which she asked for respect for the privacy of her family. This appeal follows increased media attention to co-parenting and the disclosure of Musk’s new baby from Siobhan Zilis. Thus, Musk’s family demonstrates a difficult balance between the publicity of his career and the desire to protect family life from undue scrutiny.

Large-scale family and the future of technology

At the moment, Elon Musk has twelve confirmed children, which makes his family one of the largest among modern entrepreneurs. Siobhan Zilis plays an important role not only as a mother to his three children, but also as a key executive in his tech empire, leading one of his most innovative projects. Meanwhile, Musk himself continues to be actively involved in the digital economy, being an ardent supporter of the cryptocurrency movement. His companies own significant assets, including large positions in Bitcoin, and his interest in assets such as DOGE demonstrates his broad view of the future of fintech.
