   John Ternus assumes Apple CEO role as Tim Cook becomes executive chairman

   John Ternus became Apple CEO on September 1, 2026, succeeding Tim Cook after a 15-year tenure. Cook remains with the company as executive chairman of the board. Ternus intends to use hardware as the main driver for AI innovation. Under Cook's leadership, Apple's valuation grew from approximately $350 billion to between $4.5 trillion and $4.6 trillion, fueled largely by the popularity of the iPhone.

   This transition marks the first change in Apple's top leadership in 15 years. Ternus inherits a company with a massive valuation but faces the task of integrating AI into the hardware ecosystem. Cook's shift to chairman suggests a continued influence on board-level strategy.
