Key points

  • Tim Cook's last day as Apple CEO is Monday, August 31, 2026.
  • Cook led Apple for 15 years.
  • CNBC's 'Squawk on the Street' reviewed his tenure.
  • The announcement was made via a CNBC video report.

Monday, August 31, 2026, marks the end of an era at Apple: Tim Cook is stepping down as CEO after 15 years at the helm. CNBC's 'Squawk on the Street' aired a segment reviewing Cook's tenure, highlighting the significance of the transition.

Cook's departure closes a chapter that began in 2011, when he took over from co-founder Steve Jobs. Over the past 15 years, he has led Apple through product launches, market expansions, and record financial results, though the specific achievements were not detailed in the report.

A 15-year tenure comes to a close

The announcement, made via a CNBC video report, confirms that Cook's final day is today. The segment on 'Squawk on the Street' took a look back at his time at Apple, though no further details about his successor or future plans were provided.

What the report did not say

The CNBC report did not specify who will replace Cook, nor did it mention any reasons for his departure. It also did not include any statements from Cook or Apple executives. The focus was solely on the milestone of his last day.

The open question: who leads Apple next?

With Cook's exit now official, the immediate question is who will take over as CEO. Apple has not yet announced a successor, and the CNBC report offered no hints. The company's board will need to name a new leader, a decision that will shape Apple's direction in the years ahead.

Why it matters

Cook's departure ends a 15-year era at one of the world's most valuable companies. His successor will inherit a company that has grown significantly under his leadership, and the transition could signal strategic shifts for Apple's product and market direction.
