A billboard for the new 400 Horse Casino

S&K Gaming broke ground on its new 400 Horses Casino on April 9, 2025, in Polson, Mont., according to nbcmontana.com.

The gaming and entertainment facility will be situated off Highway 93 on Irvine Flats Road. That location is tribal land. S&K Gaming is owned by the Confederated Salish and Kootenai Tribes.

Completion is anticipated in 2026.

Kraus-Anderson is serving as the contractor on the facility, which was designed by LSE Architects, according to pechanga.net.

The facility will feature a 34,227-sq.-ft. family-friendly casino with 300 gaming machines, plus room for future expansion. The casino will include 400 parking spaces and a restaurant.

Charkoosta.com reported that the project is anticipated to create more than 75 jobs.

The name, 400 Horses Casino, refers to Chief Alexander of the Pend d'Oreille Tribe. He owned the largest herd of horses and was part of the 1855 Hellgate Treaty, nbcmontana.com reported.

"Beyond direct employment, the 400 Horses Casino will create a ripple effect of economic benefits throughout the neighboring communities," said Bryon Miller, CEO of S&K Gaming LLC. "We anticipate increased patrons in our existing facilities, fostering economic entrepreneurship and creating a more vibrant economic ecosystem."

Miller said the project has been in development since 2021 and has evolved from a $10 million concept into a $30 million investment, charkoosta.com reported.

"We've actually designed the casino for phase one, and we'll get this one done in the next 14 months," Miller said. "Phase two of this development would include an event center and hotel. When you start pairing that all together, then you create the resort."

The new casino will replace the casino at KwaTaqNuk Resort and Casino in Polson, according to 500nations.com. In June 2026 the gaming equipment there will be transferred to 400 Horses and the resort will be transformed into a family-friendly facility along the southern shore of Flathead Lake.

An Indian Gaming Association representative spoke during the groundbreaking ceremony, saying the industry is strong and grew by $1.5 billion in 2023, according to nbcmontana.com.
