• CEO Tim Cook will be staying at Apple for at least three more years, Bloomberg reported.
• Cook previously said he hopes his successor will be an internal hire.

Tim Cook won't be steering Apple's ship forever.

Cook, who succeeded Apple founder Steve Jobs, helped Apple cross the $3 trillion market cap mark — and may push the company past $4 trillion by 2025.

However, 63-year-old CEO is also thinking about who will come after him. In October, Cook told singer Dua Lipa on her podcast "At Your Service" that he hoped his successor would "come from within Apple."

And according to "several people familiar with Apple's inner workings" who spoke to Bloomberg, that is a very likely scenario.

According to the Bloomberg report, Cook will not leave for at least three years, but company insiders are considering several potential CEOs.

Apple did not immediately respond to a request for comment from Business Insider.
