POLSON, Mont. — May 5, 2026 — The Indian Gaming Association joined the Confederated Salish and Kootenai Tribes and S&K Gaming in celebrating the grand opening of the new 400 Horses Casino on May 5, marking 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 new 35,000-square-foot gaming and entertainment destination represents one of the largest recent economic development projects for the Confederated Salish and Kootenai Tribes. The facility features approximately 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. Tribal leadership also shared long-term visions for future expansion opportunities surrounding the property.

The project was completed ahead of schedule and officially opened following a community celebration that included tribal leadership, elders, cultural presentations, blessings, and representatives from tribal gaming organizations 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 opening celebration, tribal leaders highlighted the economic impact the new facility will have throughout the region. According to remarks shared during the ceremony, the casino and gaming operations support more than 200 jobs within the community, with additional seasonal employment opportunities added each summer. Tribal leadership also noted the significant construction and trade employment generated throughout the development of the project.

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

“Tribal gaming is about much more than entertainment,” Chairman Bean 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 prominence in the region. Tribal officials also emphasized the importance of incorporating cultural identity and educational exhibits throughout the facility to share the history and traditions of the Confederated Salish and Kootenai Tribes with visitors and guests.

Chairman Bean also recognized the collaboration and commitment that brought the project to completion. “The Indian gaming industry has always been built on unity, relationships, and tribal leadership working together,” Chairman Bean said. “The dedication shown by the Tribal Council, S&K Gaming leadership, employees, construction teams, and the entire community made this vision possible. This facility stands as another example of what tribal nations can accomplish through sovereignty, determination, and a commitment to their people.”

The Indian Gaming Association continues its outreach efforts with tribal nations across the country to support tribal government gaming, protect tribal sovereignty, and strengthen economic opportunities for Native communities nationwide.
