NEW YORK (TheStreet) -- It's Cyber Monday and the year-end holidays are only a month away so shoppers are searching brick-and-mortar stores and the Internet for the best deals and gifts. Two of the heavyweights battling it out for sales this holiday season are Amazon.com (AMZN) and Walmart (WMT) .
"Amazon is the biggest problem for Walmart, and Walmart will be the biggest problem for Amazon," J. Rogers Kniffen Worldwide founder Jan Kniffen said on CNBC's "Squawk Box" Monday. J. Rodgers Kniffen Worldwide provides equity research, and financial and management consulting services for companies within the retail sector.
Because of the continued growth and push into e-commerce, Kniffen said Amazon will continue to find success but don't count out Walmart's ability to capture market share. "Maybe Amazon's growth slows down a little bit," he suggested.
Furthermore, Kniffen calls Walmart's Summer 2016 acquisition of Jet.com a "win" for the retail giant, and a valuable asset as it competes against Amazon. But, the move shouldn't hinder Amazon's growth.
"They get a third of all new growth in retail, and half of all new growth online. That's not going to change for a long time," Kniffen said.
