Chamath’s on-air statement in the Dec 20, 2024 episode is explicitly predictive: he and Jason talk about the upcoming holidays and say, “Three or four besties will be hitting the slopes… Three or four besties will be skiing together… We’re all going to be there, bro.” in reference to a ski trip the following week. 【6†turn3search0】

In the subsequent episode “2025 Predictions with bestie Gavin Baker”, released Jan 3–4, 2025, Jason opens by saying, “We’re all wrapping up our ski trip here,” and cues “found footage from the Bestie skiing.” The clip and banter clearly describe multiple besties skiing together: Jason narrates his own run, then Chamath’s (“There comes Champe… you really advanced this last season”), and then explicitly ranks the on-slope skiers as “me, Chamath, Friedberg in that ranking.” He praises Friedberg for having been “out there a number of days” and Friedberg confirms, “I think I skied four days.” 【5†turn2search1】 The episode description from several podcast directories also notes that the besties “welcome Gavin Baker and recap ski week,” placing this group ski trip in the immediate post-holiday window referenced on Dec 20. 【2†turn2search3】【2†turn2search6】

Putting this together: (1) on Dec 20 they predict that during the upcoming holiday period, 3–4 besties will ski together at the same destination; (2) in the very next regular episode after the holidays they explicitly recap a shared ski week, with at least three core besties (Jason, Chamath, and Friedberg) skiing on the same trip. That is sufficient to conclude that the prediction—“three or four besties will be skiing together” over that holiday period—came true.
