Limits differ greatly from sport to sport and from bet type to wager type. And even from one day to the next. On Monday, a bookmaker may accept a maximum wager of $2,500 on an NFL game. However, if more bettors weigh in and the betting market becomes more liquid by Friday, they may boost it to $50,000. These are just examples; limits change daily based on demand. The maximum bet amount that a bookmaker is willing to take on a single event is called the limit. Most events have a limit higher than what you'll find at most bookies, because they want to encourage gamblers to cross-shop across books. If you ask ten people who follow football how much they think Joe Football's favorite team will win, you're likely to get eleven different answers. By setting a limit, books make sure there's enough action in any given game to be worth their while. They also protect themselves against losses - if no one bets anything on a game, then nobody gets hurt if the games don't finish as expected. In general, the higher the limit, the more competitive the bookmaking industry will be. Higher limits mean that books can afford to take on more risk, which means better odds for consumers. It also means bigger profits when your team wins! But the highest limit set by a book isn't always the best choice for everyone.
