Pronunciation: [bˈɛtɪd ðə ɹˈant͡ʃ] (IPA) 
The phrase "betted the ranch" is spelled with two t's because the base word "bet" is spelled with a single t. The pronunciation of "bet" is /bɛt/, with a short e sound followed by a t. To make it past tense, an extra t is added, so the proper spelling is "betted" /ˈbɛtɪd/. The addition of "the ranch" to the phrase means risking a large amount or everything, as a ranch is a valuable asset.
The phrase "betted the ranch" is an idiomatic expression that originated in the United States, particularly in the realm of gambling and risk-taking. It conveys the act of wagering or staking all of one's assets, resources, or livelihood on a single outcome, decision, or action.
In a literal sense, it refers to an individual's willingness to put everything they own, often symbolized by their ranch or farm, at stake as collateral or as the sole means to procure funding for a risky venture or to settle a debt. Metaphorically, it extends beyond the realms of agriculture and gaming, encompassing a broader context of taking a monumental risk or making a significant investment, often of a financial or personal nature.
The phrase's connotation implies a high level of uncertainty, as the outcome can either result in a tremendous gain or a complete loss, leaving the individual with nothing but the "ranch" that they initially wagered. It typically signifies a bold, all-or-nothing mentality and a gamble with potentially life-altering consequences. Thus, "betted the ranch" signifies a decisive and aggressive action characterized by extreme risk-taking, often driven by the belief in the potential for a substantial reward or as a last-ditch effort to salvage a situation.
