Proposition bet


In gambling, a "proposition bet" (prop bet, prop, novelty, or a side bet) is a bet made regarding the occurrence or non-occurrence during a game (usually a gambling game) of an event not directly affecting the game's final outcome.

Proposition bets in sports are differentiated from the general bets for or against a particular team or regarding the total number of points scored. Traditionally, proposition bets can be made on outcomes such as the number of strikeouts a pitcher will accumulate in a baseball game, whether a non-offensive player will score in an American football game, which team will score the first points of the game, the discipline record of teams in a match, the timing of certain events, the number of specific events per team or in the entire match, realistically any statistically discrete event contained in a match or game could be bet on.

Fixing part of a match for a certain result in a proposition bet is called Spot-fixing.

There are a wide range of events or outcomes commonly bet on, including:

Some juristrictions do not allow casinos to offer any type of non-sport related proposition bets, but these kinds of prop bets can often be found online.

Less commonly, "proposition bet" (in this context also "one-of-a-kind bet") denotes a dare for money. The bet is on whether the "dared" person will make a given event happen. If the "dared" person accepts the bet, he will collect if he succeeds or pay if he fails.

For an example detailed in the book The Professor, the Banker, and the Suicide King, David Grey once bet Howard Lederer, a professional poker player who became vegetarian following gastric bypass surgery, $10,000 that Lederer would not eat a cheeseburger. Lederer accepted the wager, ate the cheeseburger, and won the bet.

Spot-fixing is an illegal activity where a person involved in the game takes steps to ensure a certain result for a proposition bet. Instead of fixing an entire match, or shaving points, spot fixing can be done with as little as one player, and can involve ensuring a certain outcome on only a single play, and may be completely unrelated to the points/results in a game.
