The baby is his fourth with Shivon Zilis, a Canadian executive at Musk’s neurotechnology firm Neuralink.
Elon Musk’s ever-growing brood of children has expanded once again after he confirmed the arrival of a new son named Seldon Lycurgus.
The baby is believed to be his 14thchild and the fourth he has had with Shivon Zilis, a Canadian executive at Neuralink, his neurotechnology firm.
The billionaire, now working with US President Donald Trump as the head of the Department of Government Efficiency (DOGE), has forged a reputation for giving his children highly unusual names, including Exa Dark Sideræl, Strider, Azure and X Æ A-12, known as X for short.
Zilis announced the birth on the Musk-owned social media platform X, and also disclosed the name of their third child, which had been unknown until now.
“Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was better to also just share directly about our wonderful and incredible son Seldon Lycurgus,” the 38-year-old wrote.

“Built like a juggernaut, with a solid heart of gold. Love him so much,” she wrote. Musk responded with a heart emoji.
The founder of SpaceX and Tesla believes humanity is at risk due to declining birth rates and has signalled his intention to have a large number of children.
“Bravo to big families,” the 53-year-old billionaire said three years ago. He has described falling birth rates as “the biggest danger civilisation faces by far”.
His offspring have been born to at least three different women: Zilis; the Canadian electropop musician Grimes, whose real name is Claire Boucher; his ex-wife, author Justine Wilson; and, allegedly, a glamorous young Maga influencer called Ashley St Clair, 26.

She has filed a lawsuit claiming that Musk is the father of her 5-month-old son.
St Clair says there is no doubt about the paternity of the baby. In her lawsuit, she insisted she “did not have sexual intercourse with any other male during the time the child was conceived”.
As part of her evidence, she included text messages allegedly sent to her by Musk. In one exchange, he allegedly wrote: “I look forward to seeing you and him this weekend.”
On X, she wrote: “Five months ago, I welcomed a new baby into the world. Elon Musk is the father.”
