As odds change in real time, it adds excitement and strategy to watching sports.
If you’ve ever been watching a football match and thought, “This game’s completely changed since the first half — I wish I could bet on it now,” you’ve already grasped the core idea behind in-play betting, sometimes known as live betting.
The time it takes for something that happens in real-time to display on the broadcast (known as latency) varies. For example, fans at a stadium seeing a live goal before fans watching the same match online at home. The delay for those not watching in real-time creates a potential inequality between the parties concerned in an in-play bet. The term 'courtsiding' is used to describe the act of using or transmitting information from a live sporting event for the purpose of gambling. Courtsiding involves a spectator at a sporting event taking advantage of the delay between the live action and TV or other feeds.
The spectator can use (or pass on to a third party) the real-time information to place bets on in-play markets before a betting operator, or other betting exchange user, receives the information and adjusts their odds accordingly to reflect the state of play. This results in the bettor being able to obtain more favourable odds. See our Remote Technical Standards: RTS 15 – In-play betting for more information on mandatory requirements for operators. Technological advantages can be achieved by computer software programmes and online connectivity speeds. These can both impact the speed in which a bettor can place a bet.
This advantage is seen most often on betting exchanges. Computer software known as ‘bots’ is used to monitor betting markets and place bets at a much higher rate than is possible for a person. Bots are most commonly used within in-play betting to automatically detect and place bets on stale prices, and to detect arbitrage opportunities which offer the bettor a guaranteed profit. Stale prices occur when the market has moved, but an old price that does not reflect the most recent information has been left available by a betting operator or exchange user who has not yet reacted to the new information. A bot will automatically detect this and place a bet at the favourable odds left available. Unlike traditional pre-match betting, where your wagers lock in before kick-off, in-play betting lets you act in real time. Odds shift dynamically as the game evolves — every goal, injury, penalty, or momentum change can transform the market. It’s immediate, thrilling, and for those who understand its rhythm, full of unique opportunities. But this same speed and excitement also introduce risk. Without a clear strategy and discipline, what feels like a golden opportunity can quickly become a costly mistake. This guide will walk you through everything you need to know — from how in-play betting actually functions, to the most popular sports and strategies, to the risks that every punter should understand. At its heart, in-play betting is about responding to live action.
While pre-match betting fixes your odds before the whistle blows, in-play markets stay open and constantly adjust.
You might have bet on Arsenal to win before kick-off at odds of 2.50. But if Spurs score early, those odds may drift to 5.00.
If Arsenal equalise and dominate possession, the price could shorten again to 3.00.
As the chances of winning change, an offer for cash out will increase, decrease or be removed altogether. Through our Licence Conditions and Codes of Practice, under social responsibility code provision 3.4 - Customer interaction, we require licensees to do the following. Licensees must have policies in place that: identify the types of behaviour that may trigger a problem gambling interaction have provision to identify at risk bettors who may not be displaying obvious signs of, or overt behaviour associated with problem gambling. For example, by reference to indicators such as time or money spent provide for the licensee to interact with any bettor who they suspect may be at risk of harm from gambling. Licensees must make information available to bettors on how to gamble responsibly and how to find help for problem gambling.
See social responsibility code provision 3.3.1. We expect licensees who offer in-play betting to be aware that their policies and procedures must be able to identify risks of harm from gambling to those participating in this activity. For example, where betting frequency may be exaggerated compared to other forms of gambling. Licensees must have procedures in place to ensure they can capture information about individual’s patterns of play, for example, changes in the frequency of a bettor’s gambling, or time or money spent, and use this information to identify those who may be at risk of harm, and interact with them appropriately. These procedures must properly capture information that might indicate a bettor is at risk of harm for those taking part in in-play betting as well as other forms of gambling.

Arbitrage betting is where a gambler takes advantage of a variation in odds offered by different betting operators, in order to make a profit regardless of the outcome of an event. Bots can be programmed to recognise such market opportunities and place bets to make a guaranteed profit. See our Remote Technical Standards: RTS 16 – Use of third party software for more information. This includes mandatory requirements for operators to inform bettors of their policies on the use of bots. Online connectivity speeds can depend on a range of factors such as the type of connection.
processing speeds of the computer and router or modem the level of software the computer or device is running in the background. See our Remote Technical Standards: RTS 4 – Time-critical events for more information. This includes mandatory requirements for operators to inform bettors they may be disadvantaged because of technical characteristics, such as slower network speeds or slower end user device performance. Betting operators set time delays so that when a bettor places a bet in-play there is a number of seconds between pressing the ‘place bet’ button and receiving confirmation that the bet has been made. This ensures that the odds on offer accurately reflect the progress of the event.
Sportsbooks and betting bet odds comparison website exchanges differ, as sportsbooks put in a delay to ensure their own prices are correct, whilst betting exchanges put a delay in place to protect its bettors. The length of delay varies from betting operator to betting operator depending on their own trading strategy, from event to event depending on how frequently and significantly the price could be affected and subject to the potential latency of the data source used. Bettors opting to use a ‘cash out’ facility also experience a delay between pressing the cash out button and receiving confirmation that the transaction has been processed. Cash out allows bettors to get money back on an event before it is over. Cash out offers that are subject to live betting markets can be volatile during a sporting event, increasingly so in the final stages. Bookmakers adjust their odds based on a live flow of data: scores, red cards, substitutions, even metrics like possession or shot count. Behind the scenes, algorithms calculate probabilities in milliseconds — meaning odds can change several times per minute.
