Accumulator Bet Definition

An accumulator, otherwise known as a parlay bet, refers to a single bet that links two or more bets/individual wagers into one whole bet. In order to win, the accumulator requires all wagers to win as they are each dependent on each other.


One example could include a UFC fight night. One match might only provide odds of 1.4 on the favorite to win which wouldn’t return much. However, by creating an accumulator or parlay bet with the favorites from 3 matches, the punter is able to increase the odds significantly. While a winning $10 bet would have earned $14 previously, it could be worth $200 with the parlay.

Accumulator Bet Pros and Cons
  • It is possible to stake a small amount for a much higher potential win.
  • Some accumulators have very little risk of losing with a decent potential return.
  • Individuals with an intimate knowledge of their bet subjects can often consistently win accumulators.
  • If one bet doesn’t win then the whole parlay falls apart.
  • It’s tempting to make unrealistic accumulator bets due to the potential high return.
