Football markets use the event format and a defined scoring or settlement question. Regular football playing time consists of two halves of 45 minutes plus added time. Extra time and a penalty shootout are separate phases, which matters when a market specifies regulation only. An illustrative 1–1 score after regular time remains a draw for a regulation three-way market even if a team later wins a shootout.
Price describes a conditional return
Decimal odds include the original stake in the total return. In a hypothetical example, a 100-unit stake at 2.40 returns 240 units if the selection wins: 140 profit plus the original 100. A losing selection returns nothing under ordinary win-or-lose settlement. These figures illustrate arithmetic, not a forecast.
The reciprocal of decimal odds gives a price-implied probability before adjusting for margin: 1 ÷ 2.40 is about 41.67%. It is not a measured certainty about the event. When the implied probabilities of every mutually exclusive outcome add above 100%, the excess indicates an overround in that set of prices.
Compare prices only for the same event, selection and settlement conditions. An overall winner including extra play differs from a regulation-only result. A higher printed price can therefore concern a different proposition, while fees or exchange commission can also change the amount retained.
