Available biographical sources indicate that Chamath Palihapitiya has three children from his first marriage, born in 2008, 2010, and 2012, plus two younger children with his current wife.(stg.scsonline.ca) That means his oldest child will turn 18 in 2026, and as of the evaluation date (November 29, 2025) none of his children has yet reached 18.

The prediction he made on the July 16, 2021 All‑In podcast episode (E40) was explicitly about a future point when his children are of age—either buying each one a ticket to space when they turn 18 or taking a full‑cabin family spaceflight.

Public reporting on Palihapitiya focuses on his role in taking Virgin Galactic public, later selling his personal stake, and eventually resigning from the company’s board.(cnbc.com) These sources mention his desire to one day fly to space but do not document him or his family already having gone, nor do they report him buying spaceflight tickets for his children.

Because (1) the triggering condition (his children being 18+) has not yet occurred, and (2) there is no contrary evidence that definitively shows he won’t follow through later, it is too early to judge whether this long‑dated promise will ultimately be kept or broken.
