Cakmak spoke after some U.S. lawmakers have asked regulators to look into whether the Amazon-Whole Foods deal violates antitrust laws. In June, Amazon said it planned to acquire the grocery store chain for $42 a share, in a deal valued at $13.7 billion.
"Honestly, this could be the first trillion-dollar company. I mean there is very low risk for the FTC to not approve this deal. But if they do rubber-stamp it as a yes, I think there's very little to stop this from becoming a $2,000 stock," the Monness, Crespi, Hardt & Co. analyst said on "Squawk Box."
"The internet has changed the game. As companies get bigger, it's better and better for the consumer because you're getting better prices, better experiences and better data," he added.
On Wednesday, two congressmen, Democrat Rep. Jared Polis and Republican Rep. Darrell Issa, suggested to CNBC that Amazon's planned acquisition of Whole Foods did not violate antitrust laws.
Meanwhile, Amazon is also taking another step into the food space, registering a trademark in the U.S. on July 6 for a meal-kit business.
Amazon had already been testing both food delivery, through AmazonFresh, and meal kits, which deliver fresh ingredients and recipes to subscribers. Amazon first experimented with AmazonFresh in 2007.
The news initially sent shares of meal-kit provider Blue Apron tumbling and prompted CNBC's Jim Cramer to say, "You just have to hope that you don't wake up in the morning and see Amazon has decided to get in your business."
Amazon's stock, trading around $1,065 a share in the premarket Thursday, has done well this year. The shares are up more than 40 percent year to date, according to FactSet.
The company is set to report earnings after the bell on Thursday.
