The Rainbow 6 jackpot is paid out only when there is a single unique ticket sold with all six winners. On days when there is no unique ticket, 60 percent of that day’s pool goes back to those bettors holding tickets with the most winners while 40 percent is carried over to the jackpot pool.

However, on mandatory payout days the entire pool is paid out to the bettor or bettors with the most winners in the six-race sequence.

Introduced in Maryland April 2, 2015 on opening day of Pimlico’s spring meet, the Rainbow 6 has far surpassed its previous state record carryover of $345,898.33 spanning 31 racing programs before being solved by one lucky bettor for a life-changing $399,545.94 payout April 15, 2018 at Laurel Park. The winning ticket was purchased through Maine off-track betting.

Friday’s Rainbow 6 will span Races 3-8. The sequence opens with a waiver maiden claimer for 2-year-old fillies sprinting five furlongs on the main track, and includes two races scheduled for one mile over the turf course which drew a total of 28 entries.

Highlighting the Independence Day stakes are a pair of six-furlong springs – the $100,000 Concern for 3-year-olds featuring Mighty Mischief, winner of the May 15 Chick Lang (G3) at Pimlico, and $100,000 Lite the Fuse for 3-year-olds and up led by record-setting 2020 Chick Lang winner Yaupon. Both horses are trained by Hall of Famer Steve Asmussen.

Other stakes are the $100,000 Caesar’s Wish for fillies and mares 3 and up going 1 1/16 miles and $75,000 Jameela for Maryland-bred/sired females 3 and older scheduled for five furlongs on the grass. The Lite the Fuse and Caesar’s Wish are both part of the Mid-Atlantic Thoroughbred Championship (MATCH) Series.
