Odds-on
Also known as: On
Odds where the stake exceeds the profit — implying probability greater than 50%. Fractional examples: 1/2 (risk £2 to win £1), 4/9, 2/5. Decimal odds under 2.00. Common on heavily fancied favourites and short-priced singles in racing. Some bookmakers don't offer odds-on accumulator legs at all.
