Sure Bet
Betting arbitrage ("sure bets", sports arbitrage) is an example of arbitrage arising on betting markets due to either bookmakers' differing opinions on event outcomes, or errors. When conditions allow, by placing one bet per each outcome with different betting companies, the bettor can make a profit regardless of the outcome. Mathematically, arbitrage occurs when there are a set of odds, which represent all mutually exclusive outcomes that cover all state space possibilities (i.e. all outcomes) of an event, whose implied probabilities add up to less than 1. Background Arbitrage betting involves relatively large sums of money, given that 98% of arbitrage opportunities return less than 1.2%. The practice is usually detected quickly by bookmakers, who typically hold an unfavorable view of it,{{Cite web, url=https://economics.yale.edu/sites/default/files/files/Undergraduate/Nominated%20Senior%20Essays/2015-16/Schwartz_Avery_SeniorEssay%202016.pdf, title=Arbitrage in the European Soc ...

Arbitrage
Arbitrage (, ) is the practice of taking advantage of a difference in prices in two or more marketsstriking a combination of matching deals to capitalize on the difference, the profit being the difference between the market prices at which the unit is traded. Arbitrage has the effect of causing prices of the same or very similar assets in different markets to converge. When used by academics in economics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs. For example, an arbitrage opportunity is present when there is the possibility to instantaneously buy something for a low price and sell it for a higher price. In principle and in academic use, an arbitrage is risk-free; in common use, as in statistical arbitrage, it may refer to ''expected'' profit, though losses may occur, and in practic ...

Bookmaker
A bookmaker, bookie, or turf accountant is an organization or a person that accepts and pays out bets on sporting and other events at agreed-upon odds In probability theory, odds provide a measure of the probability of a particular outcome. Odds are commonly used in gambling and statistics. For example for an event that is 40% probable, one could say that the odds are or When gambling, o .... History The first bookmaker, Harry Ogden, stood at Newmarket in 1795, although similar activities had existed in other forms earlier in the eighteenth century. Following the Gaming Act 1845, the only gambling allowed in the United Kingdom was at race tracks. The introduction of special excursion trains meant that all classes of society could attend the new racecourses opening across the country. Runners working for bookmakers would collect bets in Clock bag, clock bags. Cash flowed to the bookmakers who employed bodyguards against protection gangs operating within the vast cro ...

Advantage Gambling
Advantage gambling, or advantage play, refers to legal methods used to gain an advantage while gambling, in contrast to cheating. The term usually refers to house-banked casino games, but can also refer to games played against other players, such as poker. Someone who practices advantage gambling is often referred to as an advantage player, or AP. Unlike cheating, which is by definition illegal, advantage play exploits innate characteristics of a particular game to give the player an advantage relative to the house or other players. While not illegal, advantage play may result in players being banned by certain casinos. A skillful or knowledgeable player can gain an advantage at a number of games. Card games have been won by card sharps for centuries. Some slot machines and lotteries with progressive jackpots can eventually have such a high jackpot that they offer a positive return when played long term, according to gambling mathematics, though this requires often difficult ...

Dutch Book
In decision theory, economics, and probability theory, the Dutch book arguments are a set of results showing that agents must satisfy the axioms of rational choice to avoid a kind of self-contradiction called a Dutch book. A Dutch book, sometimes also called a money pump, is a set of bets that ensures a guaranteed loss, i.e. the gambler will lose money no matter what happens. A set of bets is called coherent if it cannot result in a Dutch book. The Dutch book arguments are used to explore degrees of certainty in beliefs, and demonstrate that rational bet-setters must be Bayesian; in other words, a rational bet-setter must assign event probabilities that behave according to the axioms of probability, and must have preferences that can be modeled using the von Neumann–Morgenstern axioms. In economics, they are used to model behavior by ruling out situations where agents "burn money" for no real reward. Models based on the assumption that actors are rational are called r ...

Mathematics Of Bookmaking
In gambling parlance, making a book is the practice of laying bets on the various possible outcomes of a single event. The phrase originates from the practice of recording such wagers in a hard-bound ledger (the "book") and gives the English language the term bookmaker for the person laying the bets and thus "making the book". Making a "book" (and the notion of overround) A bookmaker strives to accept bets on the outcome of an event in the right proportions in order to make a profit regardless of which outcome prevails. See Dutch book and coherence (philosophical gambling strategy). This is achieved primarily by adjusting what are determined to be the true odds of the various outcomes of an event in a downward fashion (i.e. the bookmaker will pay out using his actual odds, an amount which is less than the true odds would have paid, thus ensuring a profit). The odds quoted for a particular event may be fixed but are more likely to fluctuate in order to take account of the size of ...

Sports Betting
Sports betting is the activity of predicting sports results and placing a wager on the outcome. Sports bettors place their wagers either legally, through a sportsbook or bookmaker (colloquially known as "bookies"), or illegally through privately run enterprises. The term "book" is a reference to the books used by wage brokers to track wagers, payouts, and debts. Many legal sportsbooks are found online, operated over the Internet from jurisdictions separate from the clients they serve, usually to get around various gambling laws (such as the Unlawful Internet Gambling Enforcement Act of 2006 in the United States) in select markets, such as Las Vegas, or on gambling cruises through self-serve kiosks. There are different types of legalized sports betting now such as game betting, parlays props and future bets. They take bets "up-front", meaning the bettor must pay the sportsbook before placing the bet. Due to the nature of their business, illegal bookies can operate anywhere but ...

Investment
Investment is traditionally defined as the "commitment of resources into something expected to gain value over time". If an investment involves money, then it can be defined as a "commitment of money to receive more money later". From a broader viewpoint, an investment can be defined as "to tailor the pattern of expenditure and receipt of resources to optimise the desirable patterns of these flows". When expenditures and receipts are defined in terms of money, then the net monetary receipt in a time period is termed cash flow, while money received in a series of several time periods is termed cash flow stream. In finance, the purpose of investing is to generate a Return (finance), return on the invested asset. The return may consist of a capital gain (profit) or loss, realised if the investment is sold, unrealised capital appreciation (or depreciation) if yet unsold. It may also consist of periodic income such as dividends, interest, or rental income. The return may also inclu ...

Wagering
Gambling (also known as betting or gaming) is the wagering of something of value ("the stakes") on a random event with the intent of winning something else of value, where instances of strategy are discounted. Gambling thus requires three elements to be present: consideration (an amount wagered), risk (chance), and a prize. The outcome of the wager is often immediate, such as a single roll of dice, a spin of a roulette wheel, or a horse crossing the finish line, but longer time frames are also common, allowing wagers on the outcome of a future sports contest or even an entire sports season. The term "gaming" in this context typically refers to instances in which the activity has been specifically permitted by law. The two words are not mutually exclusive; ''i.e.'', a "gaming" company offers (legal) "gambling" activities to the public and may be regulated by one of many gaming control boards, for example, the Nevada Gaming Control Board. However, this distinction is not univer ...
