REFERENCE

all bets are off

idiom
Meaning

Indicates that a future event appears uncertain, especially one that before seemed more certain, and where any prior agreements are no longer valid


Origin

disputed origin

Originally 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.

Examples
SIMPLE

The weather is changing, so all bets are off for our picnic.

CONTEXTUAL

If the main investor pulls out of the project tomorrow, all bets are off regarding our expansion plans.
