Her transition into adulthood means more independence in handling endorsement deals, public roles, and her growing influence. For Kai, this moment comes at a time when she is already gaining recognition in golf and building a personal brand.
Family Background
Kai Trump is the eldest of Donald Trump Jr. and Vanessa Trump’s five children. She holds a special distinction as the oldest grandchild in the Trump family. Raised in New York City and later in Florida, Kai attended The Benjamin School, a private school in Palm Beach County.
Her family connections have naturally placed her in the spotlight, but Kai has also begun carving out her own path, particularly in sports and media.
Education and Golf Career Plans
Kai has developed a passion for golf, following in her family’s tradition of embracing the sport. In 2024, she committed to playing collegiate golf at the University of Miami, beginning in 2026. This decision showed her dedication to pursuing athletics at a competitive level while continuing her education.
Her golfing ambitions have already been supported by professional opportunities. In 2025, she signed an endorsement deal with TaylorMade Golf, joining the brand’s roster of athletes. This marked a major step in her career, especially as one of the youngest public figures in golf to secure such a deal.
Major Public Moments at 18

The attention she receives at such a young age also means she faces more scrutiny than most teenagers. From commentary on her clothing to her political associations, Kai has had to manage the pressure of public opinion while still navigating her personal growth.
