As of my last update, the Potawatomi Casino in Milwaukee, Wisconsin, does not typically offer pari-mutuel horse racing betting, including bets on the Kentucky Derby. The casino is operated by the Potawatomi tribe and primarily focuses on slot machines, table games, poker, and special events.

However, many casinos and racetracks across the United States do offer betting on major horse races like the Kentucky Derby. If you’re interested in betting on the Kentucky Derby, you might want to check with local racetracks, off-track betting facilities, or online platforms that offer legal horse racing betting in your area.

Please note that gambling laws and the availability of certain types of betting can change, so it’s always a good idea to verify the current offerings at any casino or betting facility. If you’re planning to bet on the Kentucky Derby, make sure to do so through legal and licensed channels.
