## Major businesses

Military Road is locally known as "The Strip" hosts a number of casinos and fireworks stores. These take advantage of the lack of these products in neighboring Nebraska. Legalization of recreational marijuana in South Dakota is expected to encourage the opening of similar shops selling to out-of-state customers.
North Sioux City is the former home of Gateway, Inc., the area's most well-known employer. At its height, Gateway employed over 6000 employees. After Acer Computers bought out the majority of Gateway (MPC of Idaho purchased the business portion) in late 2007, several layoffs have taken place. Fewer than 100 people have jobs at the original facility. Acer has expressed interest in selling the facility.
Other companies are renting from the facility, including Alorica, which absorbed a number of Gateway phone jobs. They are handling the AT&T account.
On August 18, 2008, MPC announced the lay-offs of 55 people currently employed (who were all former Gateway employees). On October 17, 2008, MPC laid-off 98 more employees at the former Gateway facility, many of whom were former Gateway employees.
Mars Petcare purchased the city's Menu Foods plant in October 2007 and operated it until 2011, when the plant was turned over to Mars' Royal Canin division.

In response to steadily increasing demand for their pet food products, Royal Canin announced in February 2022 that they would invest another $185 million in new production lines at their North Sioux City plant, which is expected to create 149 new jobs.
