As of August 1, 2025, Tim Cook has held the position of Apple's CEO for 5,091 days, officially eclipsing Steve Jobs' tenure of 5,090 days and thus securing his place as the longest-serving CEO in Apple's storied history. Jobs initially took on the role of interim CEO from September 16, 1997, to January 5, 2000, spanning a total of 841 days. Subsequently, he transitioned to the official CEO position from January 5, 2000, to August 24, 2011, clocking in an additional 4,249 days, which collectively amounted to 5,090 days. Since assuming the CEO mantle on August 24, 2011, Cook has consistently steered Apple's course for 5,091 days. At present, Cook shows no signs of retiring in the foreseeable future, and within Apple's ranks, there remains no definitive successor in sight.
