all bets are off
English
editEtymology
editOriginally used by sports bookmakers, and in particular horseracing. The bookmaker is not taking any more bets and all existing bets placed on the competition are now null and void. This may have been because the race was cancelled, the starting lineup was substantially changed, or due to an irregularity in the conduct of the race.
