Kai Musk’s Net Worth and Income

Kai is still in his mid-teens, so he does not have a career or a source of income. 

However, his father is a billionaire with a net worth of 285 billion USD. So, Kai also shares the same net worth by association with his father.

His Twin, Siblings, Parents, and Family

Kai was born as a triplet to his parents Elon Musk and Justine Musk. 

The couple initially had a son, Nevada, whom they lost to sudden infant death syndrome.

The couple then tried for two straight years to conceive a baby. When they could not get pregnant naturally, they took the help of IVF and gave birth to their twins Xavier and Griffin.

After welcoming their twins, the couple again took help from IVF and gave birth to Kai and his triplet brothers Saxon and Damian.

The family of seven was happy together until things started getting messy. 

Though the parents of Kai dated each other since college before marrying, they could not stay together and got a divorce ending their eight years of marriage.

They parted ways in 2008 with joint custody so that both of them could be part of the lives of their sons.

After the divorce, Elon married his second wife, Talulah Riley, though it did not last long. He even had a son with his girlfriend, Grimes.

Despite being back in the dating pool, Elon always spent as much time with Kai and his brothers as possible. He gave a luxurious life to his sons but also made sure they would not get spoiled.

Elon and Justine both raised their sons well. They kept their sons away from creating scandals like many other celebrity kids.

Because of his father, Kai and his brothers have a luxurious life. They are also close to their paternal grandmother and the siblings of their father.

Who is Kai Musk’s Girlfriend?

Kai’s father, Elon, is serious about sharing the details of the lives of his son to the public. So, he has made it a rule for his sons to stay away from social media.

Because of this, no one knows if Kai is single or seeing someone.

Education and School

Like his elder brothers and triplet brothers, Kai also attends the Ad Astra, an exclusive school established by his father.

His father founded the school especially for him and his brothers to homeschool them.


Kai is just a 18 year-old teenage so, currently he is busy in studying and has no career.

However, with all the resources and the guidance he is getting from his father, it is a no-brainer that he will be successful no matter what field he chooses.
