Hypothetical is the second foal and only winner out of Peut Etre (Whipper), runner-up in the Gr.3 Prix Fille de l'Air. Peut Etre is a half-sister to Precieuse (Tamayuz), who won the Gr.1 Poule d'Essai des Pouliches and the Grade 3 Honey Fox S., and to two further stakes-placed horses: the sprinter Baccarat (Dutch Art), placed at Listed level, and Porcelaine (Kodiac), third in the Listed Prix des Lilas.

Second dam Zut Alors (Pivotal) finished third in the Gr.3 Prix Miesque.

Third dam Zeiting (Zieten) won Listed races in the US and France. She produced three pattern winners over middle distances: Combat Zone (Refuse To Bend), winner of the Gr.2 Grosser Europa Meile, Scottish (Teofilo), winner of the Gr.3 Strensall Stakes and second in the Gr.1 Caulfield Cup, and Royal Empire (Teofilo), winner of the Gr.3 Geoffrey Freer Stakes. Her stakes-placed daughters Bikini Babe (Montjeu) and Sante (Dream Ahead) are further offspring, and Bikini Babe is the dam of La Barrosa (Lope De Vega), winner of the Gr.3 Tattersall S. and second in the Gr.3 Craven Stakes.

Further back this is the family of Eqtidaar (Invincible Spirit), winner of the Gr.1 Commonwealth Cup and a sire, and his half-brother Massaat (Teofilo), a Group 2 winner and sire who was placed in a Group 1 Classic. Their dam is a half-sister to Zeiting, and her produce also includes Mujbar (Muhaarar), winner of the Gr.3 Horris Hill Stakes.

Peut Etre's latest reported foal is a 3-year-old filly, Pourquoi Pas (Dark Angel).
