Market Structure and Settlement
A sports market is an agreement about an uncertain outcome, offered at a stated price and settled against an official result. This lesson describes who takes part, what a position is, and how a position is settled.
Understand the structure of a sports market and the rules that turn a position into a final result.
After this lesson you can name the parties to a market, describe a position in exact terms, and settle a position as a win, a loss, a push or a void.
What a market is
A market is a set of prices offered on one defined question about a sporting event. "Which team wins this game?" is a market. "Will the two teams combine for more or fewer than 44.5 points?" is another market on the same game.
Every market has three parts:
- The event. A specific game, identified by teams, date and start time.
- The question. A precise statement of what is being measured, such as the final margin or the combined score.
- The outcomes. The possible answers, each with its own price.
If the question is vague, settlement becomes a dispute. Operators therefore publish rules for each market type that state what counts, when it counts, and what happens if the event does not take place as scheduled.
The parties to a market
Two kinds of party take part in every market.
The operator is the business that publishes prices, accepts positions and settles them. The operator sets the terms. It decides which markets to offer, at what prices, and up to what size.
A participant is anyone who takes a position at the operator's price. Participants do not set the price directly. They choose whether to accept it.
The operator offers a price on each outcome, and a participant who accepts it opens a position. The operator then adjusts its prices as positions arrive and as new information appears. A price is an offer, and it can change at any time before the event starts.
The anatomy of a position
A position is a participant's commitment to one outcome in one market at one price. A position is fully described by five facts:
| Element | Meaning | Example |
|---|---|---|
| Event | The game | Team A vs Team B, Sunday 12:00 CT |
| Market | The question | Point spread, full game |
| Outcome | The side taken | Team A −3.5 |
| Price | The terms of the payoff | −110 |
| Stake | The amount committed | 110.00 |
The stake is the amount the participant commits and can lose. The return is the total paid back if the position wins: the stake plus the profit. Lesson 3 explains how to read a price such as −110. For now, it is enough to know that a price of −110 means a stake of 110 earns a profit of 100.
Two positions that differ in any one of these five facts are different positions. Team A −3.5 at −110 and Team A −3.5 at −120 are on the same outcome, but they are not the same position. The second one pays less for the same risk.
Settlement
Settlement is the process of deciding the result of a position and paying it. It happens after the event ends and the official result is confirmed. The official result is the score recorded by the league or governing body. It is not a broadcast graphic or an early report.
Every position settles in one of four ways:
- Win. The chosen outcome occurred. The participant receives the stake plus the profit.
- Loss. The chosen outcome did not occur. The participant loses the stake.
- Push. The result landed exactly on the line, so neither side won. The stake is returned with no profit.
- Void. The position is cancelled under the market rules, for example because the event was postponed past a stated deadline. The stake is returned.
A push and a void both return the stake, but they are different events. A push is a result. A void is a cancellation.
Worked example: settling a spread position
A participant holds Team A −3.5 at −110 with a stake of 110.00. The line of −3.5 means Team A must win by more than 3.5 points for the position to win. Because scores are whole numbers, that means a margin of 4 or more.
| Final score (A-B) | Team A margin | Result | Amount returned | Net profit or loss |
|---|---|---|---|---|
| 27-20 | +7 | Win | 210.00 | +100.00 |
| 24-20 | +4 | Win | 210.00 | +100.00 |
| 23-20 | +3 | Loss | 0.00 | −110.00 |
| 17-20 | −3 | Loss | 0.00 | −110.00 |
The half point in −3.5 makes a push impossible. Now consider the same participant holding Team A −3 at −110 instead.
| Final score (A-B) | Team A margin | Result | Amount returned | Net profit or loss |
|---|---|---|---|---|
| 24-20 | +4 | Win | 210.00 | +100.00 |
| 23-20 | +3 | Push | 110.00 | 0.00 |
| 22-20 | +2 | Loss | 0.00 | −110.00 |
The two lines differ by half a point. That half point decides whether a three-point win is a push or a loss. This is why the line is part of the position, and why small differences in a line can matter.
Open, close and the life of a market
A market has a life cycle. It opens when the operator first publishes a price. It stays open while the operator accepts positions and adjusts prices. It closes when the event starts, or at another stated time. The final price before the market closes is the closing price.
The price a participant receives is fixed at the moment the position is opened. Later movement in the market does not change that position's terms. A participant who took −3.5 at −110 on Tuesday keeps exactly that position, even if the market is at −4.5 by Sunday.
The opening price, the price a participant received, and the closing price are therefore three separate figures. Lesson 6 explains why the price moves between them. Lesson 7 explains why the closing price is the most useful reference.
The Odds Screen shows each game's markets with the prices currently posted by each operator, along with the opening price and the move since. Every price on that screen is an offer that can still change. On the Board, each Release records its market, line and price at the moment it was posted, and that posted price does not change afterwards, just as a participant's position keeps its original terms.
| Pitfall | What it costs |
|---|---|
| Reading the slip without the line | Team A −3 and Team A −3.5 settle a three-point win differently: a push returns 110.00, a loss returns 0.00. |
| Treating a void as a push | Both return the stake. A void is a cancellation under the rules, not a result, and it tells you nothing about the price. |
| Grading from a broadcast score | Only the official result settles. A stat correction after the final can turn a settled position the other way. |
- Market: a set of prices on one defined question about a sporting event.
- Operator: the business that publishes prices, accepts positions and settles them.
- Participant: anyone who takes a position at the operator's price.
- Position: a commitment to one outcome, in one market, at one price, for a stated stake.
- Settlement: deciding and paying the result of a position from the official result.
- Push: a result exactly on the line; the stake is returned with no profit.
Questions
Open the Position Record and write one position in all five facts: event, market, outcome, line and price, plus the stake. Use any game on the Odds Screen. Leave the result column blank until the official result is posted.
Position Record
Position Record. Ledger template (PDF worksheet, one row per position).
Columns: Date and time taken | Event | Market | Outcome | Line | Price | Stake | Official result | Settles (win, loss, push, void) | Amount returned | Net.
| Date and time taken | Event | Market | Outcome | Line | Price | Stake | Official result | Settles | Amount returned | Net |
|---|---|---|---|---|---|---|---|---|---|---|
| Example: Sun 11:02 AM | Team A at Team B, Sunday | Spread, full game | Team B | +4.5 | −110 | 110.00 | Open | Open | Open | Open |
The Example row stays open on purpose. The lesson never states the result of the Team A at Team B game.
Lesson 2 delivers the market types: moneyline, spread, total, segment, team total, player and outright, and what each one pays.
