Musk, who published a Tweeter
on May 24, saying that “the birth rate in the United States has been below minimum sustainable levels for about 50 years” and pinned it to the top of his Twitter account of more than 100 million followers, quietly spawned the children with Shivon Zilis, who works for Musk at the company that hopes to develop an implantable computer chip for the human brain, according to documents obtained by Business Insider.
The outlet obtained court documents regarding changing the children’s legal names to incorporate Musk’s surname and Zilis’s as middle names. CNN Business could not independently confirm the contents of the documents, but a Travis County, Texas court filing obtained by CNN Business said the name change petition was originally filed in April 2022 and granted in early May – matching the dates of documents published by Business Insider. These documents contain the court stamp as well as Musk’s signature, listing him as the father and Zilis as the mother.
Musk did not immediately respond to requests for comment sent to representatives from Tesla, SpaceX and Neuralink.
Zilis’ professional ties to Musk date back to at least April 2016, according to her LinkedIn profile, when she became an advisor at OpenAI. Musk is one of the co-founders of OpenAI, a nonprofit research lab whose mission is “to ensure that general artificial intelligence benefits all of humanity.”
In August 2020, Musk hosted a live-streamed event intended to showcase advancements in Neuralink technology, which he had implanted in a pig. Nearly a year later, Neuralink claimed monkeys could play Pong after the company’s chips were inserted into their brains. But, more recently, Neuralink has had to address concerns about its testing practices, denying animal cruelty claims while confirming earlier this year that monkeys died in testing.
According to Zilis’s LinkedIn, she worked for Tesla and Neuralink from May 2017; and currently works as Director of Operations and Special Projects at Neuralink. In 2020, Zilis became a board member of OpenAI. Prior to working at companies run by Musk, Zilis worked for venture capital fund Bloomberg (which made him a Forbes 30 under 30 list for venture capital in 2015), as well as IBM. She has also served on the boards of at least two other AI-related organizations. Zilis did not immediately respond to a request for comment.
This is the second set of twins Musk has reportedly fathered. Musk and his first wife, Justine, had twins in 2004 before welcoming triplets two years later. (The two, who were married from 2000 to 2008, lost their first child; Justine, an author, wrote about what it was like to be married and divorced Musk for Marie Claire magazine in 2010. ) Musk went on to have two children with musician Claire Boucher, better known as Grimes. Their second child was born in December 2021 through a surrogate mother.
