The Cotillion Stakes is one of the most important late season Grade 1 races for three year old fillies in the United States. The 2026 edition is scheduled for Saturday, September 19 at Parx Racing in Bensalem, Pennsylvania.
2026 Cotillion Stakes
Parx Racing has confirmed a $1 million purse and a distance of one and one sixteenth miles on dirt. The Cotillion is one of the headline races on Pennsylvania Derby Day and is scheduled as Race 13 on the program.
OTB Bet is not treating the runner list currently displayed on the Parx event page as the confirmed 2026 field because those names correspond to the prior edition. This guide will add the current field, post positions and morning line only after they can be verified against current official entries.
Why the Cotillion matters
The Cotillion gives three year old fillies a Grade 1 target after the spring classics and summer championship races. It can help define the division late in the season and offers a major opportunity for fillies building toward older competition.
The race fits naturally into the same season arc as the Kentucky Oaks and other major dirt races for fillies. It also provides useful context for readers following the path toward the Breeders’ Cup Distaff.
Race conditions and course
The 2026 Cotillion is restricted to three year old fillies and is run at one and one sixteenth miles on the Parx main track. The distance rewards tactical position, efficient turns and the ability to finish strongly after racing close to the pace.
Parx Racing lists gates opening at 10:00 a.m. on September 19, with first live post at 10:35 a.m. The Grade 1 Pennsylvania Derby follows the Cotillion later on the same card.
What to watch next
The next important checkpoint is the release of a clearly current official field. Until then, contender lists and prices should be treated as provisional rather than race day facts.
OTB Bet will add confirmed entries, scratches, rider changes and the official result only after they are verified from current authoritative information.
