Evidence shows that the All-In podcast did in fact hold a second All-In Summit in 2023. The All-In podcast’s Wikipedia entry explicitly notes that “The second summit took place in Los Angeles from September 10 to 12, 2023,” describing it as the follow-up to the inaugural 2022 Miami summit. (en.wikipedia.org) Additional references, such as posts and talks labeled as recorded at “All-In Summit 2023 at Royce Hall on UCLA's campus in Los Angeles,” further confirm that the 2023 event occurred. (podcasts.apple.com) Since the prediction was that there would be a second All-In Summit in 2023, and such a summit did occur, the prediction is right.
