The Rainbow 6 carryover at Laurel Park is up to $154,232 for Friday's card.
There has not been a single winning ticket on the Rainbow 6 in 23 racing cards. The last time the jackpot was hit was Feb. 4.
The carryover is a record for Laurel Park. The biggest carryover since the bet began in Maryland was $275,322 at Pimlico on June 5, 2015. There was a mandatory payout on that pool June 6, the day American Pharoah won the Belmont Stakes. The total June 6 pool was $798,206.
The feature race on Friday at Laurel is a high-level optional-claiming sprint in which El Areeb will make the third start of his comeback.
