The 2002 Breeders' Cup betting scandal was an incident that arose when computer programmer Chris Harn conspired with two friends, Derrick Davis and Glen DaSilva, to manipulate bets in the 2002 Breeders' Cup, held at Arlington Park in Arlington Heights, Illinois. This enabled him to arrange a $3 million USD payout to the trio. The scam was exposed when 43-1 longshot Volponi won the Breeders' Cup Classic. This unanticipated victory made Davis the sole winner of the Pick 6 jackpot. Eventually, Harn, Davis and DaSilva entered pleas of guilty.

The three men had been friends and fraternity brothers at Tau Kappa Epsilon during their days at Drexel University. DaSilva now lived in New York City while Davis lived in Baltimore. Davis and DaSilva traveled to several tracks in New Jersey, New York, and Pennsylvania to cash the vouchers. The three men then split the winnings. However, Harn soon realized that if they kept it up too long, they'd eventually be tracked down. He looked for a way to get one big payoff that could allow him to easily cover his tracks. He found it in the Breeders' Cup, the richest day in American horse racing. Harn decided to go for the Ultra Pick 6, in hopes of scoring a win by picking the winners of the six major races of the competition—the Classic, Turf, Sprint, Distaff, Juvenile and Mile.
