Evidence shows Jason Calacanis and David Sacks did, in fact, spin up recurring All‑In–related “post shows” on the Callin platform. A September 2021 analysis of Callin notes that Sacks hosts an “All‑In Afterparty” companion show on Callin in addition to his other Callin shows, explicitly framed as an in‑between show for the All‑In Podcast. (moorinsightsstrategy.com) The All‑In feed itself lists an episode titled “Leaked tapes: Sacks vs. Jason origins | All‑In After Party on Callin,” indicating an After Party format hosted on Callin with both Sacks and Jason actively participating. (bilingualpodcastplayer.com) Separately, a Callin-based spinoff called “After All In with JCal” is described as a live fan Q&A where listeners can “Talk to JCal about the last episode 48 hours after the episode drops,” with instructions to use the Callin app to listen live and call in, matching the idea of a recurring, roughly-two-days-later post show for interacting with fans in a smaller group setting. (podbay.fm) Taken together, these Callin shows match the substance of the prediction (Callin-hosted post shows tied to recent All‑In episodes, involving Jason and Sacks and enabling live fan interaction), so the prediction is best judged as having come true.
