Montana: IGA joins Confederated Salish and Kootenai Tribes to open 400 Horses Casino

The Indian Gaming Association joined the Confederated Salish and Kootenai Tribes and S&K Gaming on May 5 to celebrate the grand opening of the new 400 Horses Casino in Polson, Montana. Tribal authorities called it "a major investment in tribal economic development, job creation, and the continued advancement of tribal sovereignty through tribal government gaming."

Located near Highway 83 and the Polson Airport, the 35,000-square-foot facility features nearly 300 gaming machines, expanded guest amenities, outdoor patio areas overlooking Flathead Lake and the Mission Mountains, and the new “371” restaurant, named after the deepest point of Flathead Lake.

The project was completed ahead of schedule and officially opened during a community celebration attended by tribal leaders, elders, gaming representatives, and regional tribal governments.

“This beautiful facility reflects the strength and vision of the Confederated Salish and Kootenai Tribes and their commitment to investing in the future of their people,” said David Z. Bean, Chairman of the Indian Gaming Association. “Tribal gaming continues to create opportunity, support families, and strengthen communities across Indian Country while protecting and exercising tribal sovereignty.”

During the ceremony, tribal officials highlighted the project’s economic impact across the region. According to remarks shared during the event, casino and gaming operations currently support more than 200 jobs in the community, with additional seasonal positions created each summer. Leaders also noted the substantial construction and trade employment generated during the development of the project.

Bean joined tribal leaders and community members in recognizing tribal gaming as a key driver of self-determination and economic independence for tribal nations.

“Tribal gaming is about much more than entertainment,” he said. “It is about creating opportunities for future generations, strengthening tribal economies, and ensuring tribes have the ability to provide for their communities through their own success and leadership.”

The name “400 Horses” honors Chief Alexander of the Pend d’Oreille people, a respected tribal leader remembered for his influence throughout the region. Tribal officials also emphasized the importance of incorporating cultural identity and educational exhibits within the facility to share the history and traditions of the Confederated Salish and Kootenai Tribes with visitors.

“The Indian gaming industry has always been built on unity, relationships, and tribal leadership working together,” Bean said. “The dedication shown by the Tribal Council, S&K Gaming leadership, employees, construction teams, and the entire community made this vision possible.”
