An event listing describes “The All-In Summit 2025” at the Shrine Auditorium and Expo Hall in Los Angeles running from September 7 to September 9, 2025, with on‑site programming, food, and networking, which clearly indicates an in‑person format.

(iren.com) The All-In podcast’s own history (via a summary article) states that the 2025 summit was held in Los Angeles from September 7 to 9, listing it as the next annual summit after the 2022, 2023, and 2024 events—making it the fourth All-In Summit.
