With the competition mounting, Cramer said Apple's lead could still fade. He turned to Amazon CEO Jeff Bezos' annual shareholder letter, released Wednesday.
In it, Bezos wrote that Amazon's paid delivery service, Amazon Prime, now has 100 million worldwide members and that more people joined Prime in 2017 than in any other year.
And despite President Donald Trump's ostensibly tax-related grudge against the e-commerce giant, the company seems to be weathering the Twitter-storm. Also in the shareholder letter, Bezos wrote that over five billion items were shipped to Prime members globally just in 2017.
"If the president stops tweeting and the [Supreme] Court rules in favor of the third-party sellers [and] Amazon's lucrative web services business stays strong, [the] trophy goes to Amazon," Cramer said.
