All bets are off
Meaning
This phrase means that previous plans, agreements, or certainties are no longer valid, and the situation has become entirely unpredictable.
Origin
The phrase originates directly from the exhilarating world of gambling, particularly horse racing, where "bets" refer to the wagers placed on a race's outcome. If unforeseen circumstances arose—such as a horse being scratched, a major rule change, or the race being cancelled—bookmakers would declare "all bets are off." This pronouncement signified that all wagers were voided, and money would be returned, completely nullifying any prior agreements and expectations. From the thrilling chaos of the racetrack, this vivid idiom quickly galloped into general usage, becoming a potent metaphor for any situation where previous plans, assumptions, or certainties are suddenly invalidated, leaving the future wide open and unpredictable.
