Boardwalk Empire Wiki

Sidereal is a racehorse owned by Arnold Rothstein and trained by Max Hirsch. The character is based on a real horse of the same name.


Season 2[]

Trainer Max Hirsch has been impressed with the form of Sidereal, who remains a relative unknown. Sidereal's owner Arnold Rothstein expects to net large winnings by making Sidereal a late entry on the busy 4th July 1921 race day at the Aqueduct Racetrack. He expects to ensure long odds with the late entry with an unknown horse. He will sustain the odds by surreptitiously betting through intermediaries. He believes that concealing his large bets while the bookmakers are too distracted to properly adjust the odds will keep them in his favour; a scheme he calls unorthodox but not illegal.
