Explanation of the term “sure bet”

A sure bet or arbitrage bet is a term used to refer to a bet that guarantees a win regardless of the outcome of the event. This is achieved by finding odds for all possible options that overlap and fill losses.

Typically, bookmakers and exchanges deduct commissions that range from 2% to 8%. In this case, the odds of two evenly matched tennis players winning would be 1.90.

Sometimes, however, betting companies offer improved odds or do not consider the odds of competing bookmakers. It is possible that one site offers odds of 2.05 for the No. 1 tennis player, while the other offers 2.10 for his opponent to win. By taking advantage of these estimates, you can make a sure bet and win, no matter the ultimate winner of the match.

Bet round amounts because some online operators monitor arbitrage and block users who apply them. It’s also important to take into account the bet limits and any fees some platforms charge. Using an exchange betting calculator will help you determine what the net profit is on back and lay bets.
