Bally’s Thunder Plains Park races toward August completion before debut meet

Bally’s Thunder Plains Park is trying to turn a construction site about 10 miles east of Cheyenne into something Wyoming horseplayers can actually bet on by late September: a 19-day mixed-breed live meet built around a $1.6 million purse program, or $100,000 a day, at the state’s first full 1-mile racetrack.

That timetable tightened after Shannon Rushton, Bally’s Wyoming’s executive director of operations and racing, told the Wyoming Gaming Commission on May 15 that the goal is to have the facility ready by Aug. 1. That date matters because the commission has to inspect the finished project before racing can begin, and Thunder Plains is chasing an opening that would make it more than a promise on a dirt lot.

The tangible pieces are starting to stack up. Building materials for five barns, each measuring 250 by 80 feet, arrived ahead of schedule on May 12. Concrete foundations are next, and more material for 400 stalls is due soon. For horsemen, that is the difference between a speculative launch and an actual racing barn complex with enough room to stage a meet that expects a mixed field of Thoroughbreds, Quarter Horses, American Paint horses and Appaloosas.

Thunder Plains’ debut has been framed around a live meet beginning Sept. 25, even as Wyoming regulators had already approved a 16-day fall meet for 2026 that runs from Oct. 2 through Nov. 1, with racing on Fridays through Sundays and on Indigenous Peoples’ Day, Oct. 12. However the calendar settles, the real question is whether the track can open cleanly and stay open long enough to matter. Bally’s is betting that it can, and that the site can become part of a regional racing circuit instead of another unfinished Western racing project.

That ambition is why the company’s move to take majority ownership in February 2026, after the permit transfer from Cowboy Racing to Bally’s Wyoming, still looms over the opening. The Edwards family kept a 20% minority interest, and Bally’s has said experienced Arapahoe Park personnel will help staff the first season. That cross-pollination is no small thing after Arapahoe’s own 2025 problems with electrical-code issues in renovated barns and a test barn bathroom that needed ADA compliance before racing could proceed. Thunder Plains is now the cleaner slate, and the first real test of whether Wyoming racing can build something durable rather than simply patching up old problems elsewhere.
