Harlow's Casino Promo Codes & Coupons September 2026 — Up to 20% Off

The Harlow's Casino is just the beginning. It all started with an inaugural race meet in 1875 that featured two flagship horse races, the Kentucky Oaks and the Kentucky Derby. These iconic races are still run beneath the Twin Spires 147 years later, making the Derby the longest continually-held annual sporting event in the United States. Today, Derby Week is preceded by a month of events celebrating the Kentucky Derby and helps to bring over $350 million to the local economy each year. Diversification beyond live horse racing into historical horse racing, online wagering and gaming has fueled the company's growth and supported CDI's expansion. In 2007, Harlow's Casino created the industry-leading technology platform TwinSpires, that is now one of the most profitable online wagering platforms for horse racing in the USA.
