The claim is strongly supported by the BBC article "Apple names new chief executive to replace Tim Cook," which explicitly says Apple named John Ternus CEO effective 1 September 2026 and Tim Cook will become executive chairman. The BBCBreaking X post repeats the same facts and links to that article. The unusual_whales X post independently relays the same claim while attributing it to CNBC. In addition, search results identify a matching CNBC article titled "Apple taps John Ternus as CEO to replace Tim Cook, who ... - CNBC" stating Apple said Ternus is succeeding Cook and Cook will become executive chairman on Sept. 1. Although an official Apple source was not retrievable within tool limits, the combination of BBC's reported article, BBC's own social post, and corroborating CNBC discovery makes the claim very likely true.
