Green Empress wins Prix Marcel Boussac for Joseph O’Brien at ParisLongchamp

Green Empress provided trainer Joseph O’Brien with another big-race success when she narrowly held off Data to win the Prix Marcel Boussac, the first race at ParisLongchamp on Arc day, in live updates of the Prix de l’Arc de Triomphe 2026.

O’Brien said: “It’s really special for us to have a Group One winner on this day and she has been progressive – she’s only ever been beaten by Sun Goddess all year. She has a super pedigree, being by Saxon Warrior out of a Sea The Stars mare. We see her as a miler that might go 10 furlongs at some stage.”
