"Betting the farm" is an idiom that refers to taking a huge risk or investing everything a person has in a particular venture. However, there are a number of synonyms that can be used in place of this phrase to express the same sentiment. Some of these phrases include "putting all your eggs in one basket," "going all in," "taking a leap of faith," "rolling the dice," "going for broke," and "betting the ranch." All of these phrases imply a level of uncertainty and danger with a high reward if successful, but also carrying with it a high risk of loss. It is important to carefully consider the potential outcomes before embarking on such a venture.
