Which of Elon Musk’s Children Were Born Through Surrogacy?
Elon Musk and musician Grimes welcomed two children through surrogacy, according to public reporting: daughter Exa Dark Sideræl, born in December 2021, and son Techno Mechanicus, born in June 2022. Grimes discussed their daughter’s birth in a 2022 interview, while news of their younger son emerged in 2023.
Their story has prompted questions about how surrogacy works, why families consider it, and what intended parents should understand before beginning their own journey.
At ACRC Global, we help intended parents explore U.S. surrogacy through education, personalised matching and ongoing coordination. Here, we separate the publicly reported facts from the broader questions families often ask about this path to parenthood.
What Have Elon Musk and Grimes Shared About Surrogacy?
Exa Dark Sideræl: Born in December 2021
In a March 2022 interview with Vanity Fair, Grimes revealed that she and Musk had welcomed their daughter, Exa Dark Sideræl, nicknamed “Y,” through a surrogate in December 2021.
Grimes described difficulties during her first pregnancy when explaining their decision to use surrogacy for their second child. Her comments reflect her personal experience; they do not establish a medical diagnosis or explain another family’s circumstances.
Techno Mechanicus: Born in June 2022
Techno Mechanicus, nicknamed “Tau,” was reportedly born through surrogacy in June 2022; his birth became public in September 2023. The Los Angeles Times reported the details based on Walter Isaacson’s biography of Musk.
These are previously reported births, rather than announcements of new babies in 2026.
What Is Gestational Surrogacy?
Gestational surrogacy is an arrangement in which a gestational carrier carries a pregnancy for intended parent or parents using an embryo created through in vitro fertilisation, or IVF. The carrier’s own egg is not used, so she has no genetic relationship to the child.
The embryo may be created using eggs and sperm from intended parents, donors, or a combination of both. This differs from traditional surrogacy, in which the surrogate’s own egg is used. The American Society for Reproductive Medicine explains this distinction.
Public reports about a celebrity’s use of surrogacy do not necessarily disclose the source of eggs, embryo testing, treatment protocols or other private medical information.
Why Do People Consider Surrogacy?
People may explore gestational surrogacy when carrying a pregnancy is medically impossible or would pose significant health risks. It can also provide a family-building option for people who need a gestational carrier, including male same-sex couples and single men.
A fertility specialist should assess the medical circumstances and explain appropriate options. A celebrity’s experience cannot determine whether surrogacy is suitable for someone else.
For prospective parents, useful starting questions include:
Do we already have embryos, or do we need to discuss embryo creation?
Will egg or sperm donation be part of our journey?
What medical advice have we received so far?
What support do we need with matching, communication and practical planning?
What budget and timing should we prepare for?
You can explore these questions through ACRC’s surrogacy and fertility services for intended parents.
What Does the U.S. Surrogacy Process Involve?
A surrogacy journey brings together intended parents, a gestational carrier and professionals with different responsibilities. ACRC’s surrogacy process for intended parents includes the following stages.
1. Consultation and Planning
An initial consultation is an opportunity to discuss your family-building goals, current circumstances and questions. It also helps identify which medical, legal and financial conversations should happen next.
2. Screening and Matching
Matching involves more than reviewing a profile. Communication preferences, expectations and practical considerations matter alongside professional screening.
ASRM guidance recommends medical evaluation, infectious disease testing, psychological assessment and counselling as part of gestational carrier preparation.
3. Independent Legal and Financial Arrangements
Intended parents and the gestational carrier need independent legal representation. Attorneys address agreements and applicable parentage requirements before treatment proceeds. Insurance and financial arrangements also require careful planning with the relevant professionals.
4. Embryo Transfer and Pregnancy Care
The treating fertility clinic directs medical screening, treatment and embryo transfer. If pregnancy is established, care continues under the relevant clinicians, with coordination and communication throughout the journey.
5. Birth and Postpartum Planning
Preparation includes hospital arrangements, practical support, legal-parentage steps and the transition after delivery. The details and timing depend on the individual journey.
What Can Intended Parents Learn From Celebrity Surrogacy Stories?
Celebrity stories can introduce people to surrogacy, but a headline provides only a small part of a family’s experience. For your own planning, focus on the information that helps you make informed decisions.
Ask for a clear explanation of responsibilities. Understand what the agency coordinates, what the clinic manages and what independent attorneys advise on.
Discuss expectations early. Communication during pregnancy, privacy, support and birth planning deserve thoughtful conversations.
Request a personalised cost breakdown. Ask which services are included, which expenses are separate and what circumstances could change the budget.
Make room for everyone’s wellbeing. Intended parents and gestational carriers both need respectful communication, informed choices and appropriate support.
Frequently Asked Questions About Elon Musk and Surrogacy
Did Elon Musk and Grimes use a surrogate?
Yes. Public reporting identifies their daughter Exa Dark Sideræl and son Techno Mechanicus as having been born through surrogacy. Grimes discussed their daughter’s birth in a 2022 interview; reporting about their younger son followed in 2023.
Were all of Elon Musk’s children born through surrogacy?
No. Reporting distinguishes between children born through surrogacy and other births. IVF and surrogacy are different: IVF describes how embryos are created, while surrogacy involves another person carrying the pregnancy. An IVF report alone does not establish that a surrogate was involved.
Is a gestational surrogate genetically related to the baby?
No. In gestational surrogacy, the carrier’s own egg is not used. The child’s genetic connection comes from the egg and sperm used to create the embryo.
How much does surrogacy cost?
Costs depend on the program, medical needs, insurance arrangements and individual circumstances. For planning information, visit ACRC’s surrogacy cost page, then book a consultation to request the current cost sheet and discuss your needs.
