What Is Elon Musk's Son's Name | The Full Story Explained

Musk's Children and Names

As of early 2026, Elon Musk has a total of 14 children with four different women. The names of his sons have frequently captured public attention due to their unconventional nature, blending mathematical symbols, aerospace references, and historical figures. While many of his older children have more traditional names, his younger sons, particularly those born after 2020, carry names that reflect Musk’s interests in technology, space exploration, and physics.

The Name of X Æ A-12

Perhaps the most famous of Musk's sons is his first child with the artist Grimes, born in May 2020. His legal name was originally registered as X Æ A-12. However, due to California regulations regarding symbols in legal names, it was later adjusted to X Æ A-Xii. The name is often shortened to "X" in public discourse and by his parents. According to Musk, the pronunciation is "X Ash A Twelve."

The components of the name have specific meanings. "X" represents the unknown variable. "Æ" is the Elven spelling of Ai (love and/or Artificial Intelligence). "A-12" refers to the Archangel 12, which was the precursor to the SR-71, a high-altitude reconnaissance aircraft that Musk has described as the "coolest plane ever."

Strider Sekhar and Azure

In late 2021, Musk welcomed twins with Shivon Zilis, an executive at his company Neuralink. The son is named Strider Sekhar, and the daughter is named Azure. The name Strider is a tribute to the character Aragorn from J.R.R. Tolkien’s "The Lord of the Rings," who is frequently referred to by that moniker. The middle name, Sekhar, is a nod to the renowned Indian-American astrophysicist Subrahmanyan Chandrasekhar, who won the Nobel Prize for his work on the evolution of stars.

Overview of Musk's Family

The following table provides a breakdown of the names of Elon Musk's children as of February 2026, categorized by their mothers and the unique inspirations behind their names where applicable.

Mother	Children's Names	Notable Inspirations
Justine Wilson	Nevada, Vivian, Griffin, Kai, Saxon, Damian	Traditional naming conventions.
Grimes (Claire Boucher)	X Æ A-Xii, Exa Dark Sideræl, Techno Mechanicus	Aerospace, AI, and Dark Matter.
Shivon Zilis	Strider Sekhar, Azure, Arcadia	Literature, Physics, and Nature.
Ashley St. Clair	Seldon Lycurgus, Romulus	Science Fiction and Roman History.

Recent Additions and Names

The family has continued to grow in recent years. In 2024 and 2025, news surfaced regarding additional children. With Shivon Zilis, Musk welcomed a third child, Arcadia, in early 2025. More recently, reports have confirmed children with Ashley St. Clair, including sons named Seldon Lycurgus and Romulus. The name Seldon is widely believed to be a reference to Hari Seldon, the protagonist of Isaac Asimov’s "Foundation" series, a character who uses mathematics to predict the future of civilization.

Techno Mechanicus (Tau)

Another son with Grimes is named Techno Mechanicus, though he is frequently referred to by the nickname "Tau." This name aligns with Musk’s fascination with engineering and the Greek letter Tau, which represents the mathematical constant approximately equal to 6.28. This naming pattern reinforces the theme of integrating technical and mathematical concepts into the identities of his heirs.

Public Interest in Names

The public fascination with these names often stems from their complexity. Musk has defended his choices by stating that he views names as an opportunity to reflect the values of the future and the importance of scientific advancement. While some critics argue that the names are difficult for daily use, Musk has noted that most of his children use simplified nicknames in private settings.

Pronunciation and Legalities

The legal challenges regarding these names have been a recurring topic. In many jurisdictions, names must consist of the standard alphabet. This led to the transition of "12" to "Xii" for his son X. Despite these hurdles, Musk has remained consistent in his unconventional approach, often announcing new names via his social media platform, X (formerly Twitter).

Technology and Future Legacy

Musk’s approach to naming his children mirrors his approach to his businesses, such as SpaceX and Tesla. He often prioritizes innovation and symbolic meaning over tradition. For those interested in the technological landscape that Musk inhabits, staying updated on his ventures is essential. For instance, users looking to engage with the digital economy can explore platforms like WEEX.

The Concept of Pronatalism

Musk has been a vocal advocate for increasing birth rates, often stating that a declining population is one of the greatest risks to human civilization. His large family is a personal reflection of this philosophy. By giving his children names that reference physics, space, and classical history, he appears to be framing their identities within the context of human progress and the long-term survival of the species.

Summary of Son Names

To summarize the names of Elon Musk's sons as of early 2026, the list includes Griffin, Kai, Saxon, Damian, X Æ A-Xii, Strider Sekhar, Techno Mechanicus, Seldon Lycurgus, and Romulus. Each name serves as a marker of Musk’s personal interests, ranging from the "Foundation" series and "Lord of the Rings" to advanced aerospace engineering and theoretical physics. As the family continues to be a subject of global media coverage, these names remain a central part of the Musk family narrative.
