Answer by icprofit6000
I did some web searching and based on the information I gather.

YRC Worldwide is the largest freight company in the US. I just not sure if it moves the sea container or not. It more of a trucking company

FedEX is the largest US freight company that I know that moves sea containers. I measured largeness by the size of the company (in market capital) not in amount of freight moved or the size of their ocean fleet

DryShips Inc. owns and operates drybulk carriers that operate worldwide. It may be the largest container business Mkt Cap: 2.84B

UPS (Mkt Cap 74.32B) Supply Chain Solutions offers a full array of global ocean freight and transportation services. They handle almost any size shipment, from less-than-container loads to full container loads, special equipment, and oversized cargo.
