The price on most betting exchanges is unbeatable without significant resources (it is set based on Asian books, they will open lines to sharps before betting exchanges list the market). The price on parlays, with the huge spread, is far more vulnerable because there is no large market for these events. Prices for large events are mostly gathered from third parties, parlays will tend to be priced in-house. This is part of the reason why bookmakers control who can bet on what on their site. If they opened parlay line with $100k limit to anyone, they would be bankrupted by the end of the day. The purpose of these bets is to create a product that is exciting for customers and is economic for them to provide...but that requires there to be limit on how much customers can bet. The most profitable product are the handicap markets and point spreads even though the margin for these is usually low single digits. Asian books usually only provide these markets...but the problem is that customers don't like these as much as parlays. The product is entertainment.
