Key points

  • You select three runners and win only if they finish 1st, 2nd, and 3rd in the exact order you chose.15
  • A combination trifecta lets the selected horses finish in any order among the top three, but costs more to stake.56
  • Trifecta is an exotic wager within parimutuel betting, meaning payouts depend on the total pool and number of winning tickets.2

How trifecta betting works

  1. Pick three horses you think will finish first, second, and third.
  2. Specify the exact order of finish (e.g., Horse A first, Horse B second, Horse C third).
  3. Place your bet before the race starts; the minimum stake is typically £2 for Tote bets.6
  4. If your horses finish in the exact order you predicted, you win a share of the trifecta pool.

Common questions

How does trifecta betting work?

You pick three horses to finish first, second, and third in the exact order. If they do, you win. Some operators offer a combination trifecta where the order doesn't matter, but the stake is higher. Payouts come from a parimutuel pool, so they vary by race.
