KEY TAKEAWAYS
A futures bet is a wager on an outcome that will be decided later, often weeks or months away. Typical examples are the winner of a championship, a season award, or the number of wins a team will record. The bettor picks an outcome, takes the posted odds today, and waits until the event is settled to find out whether the bet wins.
Futures belong to the broader family of proposition bets, but they work differently from a single-game wager. The odds are usually long, many outcomes compete in the same market, and the sportsbook’s margin is often much larger than on a standard two-way bet. A price such as +600 looks generous, yet it hides a built-in cost that this guide explains with exact numbers.
This guide explains how futures are priced, how to convert odds to implied probability, how to measure the hold in a multi-outcome market, and which settlement rules vary. All teams and prices are hypothetical, and nothing here recommends a bet.
What a Futures Bet Is
A futures market lists many possible outcomes at once, such as eight teams that could win a title, with a separate price for each. A bettor chooses one outcome and bets on it, and the bet wins only if that outcome happens. Futures are one type of prop bet, and the guide to what prop bets are explains how futures sit alongside player and game props.
Common futures include a league or tournament champion, a conference or division winner, a season win total over or under, an individual award, and a team making or missing the playoffs. The defining feature is time: the stake is committed now, and the result arrives after many games or events have been played.
Because the odds are posted for a long horizon, they can change many times before the bet is settled. A bettor who bets today locks in today’s price, even if the same outcome later moves to a shorter or longer price. The price at the time of the bet is the price that pays, which is why checking it before confirming matters.
How Futures Odds Work
Futures are normally listed in American odds. A positive number shows the profit on a $100 stake, so +600 pays $600 profit on $100 and returns $700 in total. A negative number, which appears for heavy favorites, shows how much must be risked to win $100. The guide to reading American odds covers both directions in detail.
Each price implies a probability: for positive odds, 100 ÷ (odds + 100). At +600 that is 100 ÷ 700 = 14.29%. Add up the implied probabilities of every outcome in the market, and the total will be more than 100%. In a fair market of mutually exclusive outcomes the total would be exactly 100%, since exactly one outcome happens. The excess is the sportsbook’s margin, spread across all of the prices.
Settlement rules for futures vary. A bet usually loses when the chosen team is eliminated, and it wins when the outcome is confirmed. Rules differ for ties and dead heats, for a team withdrawing, for events that are cancelled or shortened, and for the date on which the result is considered final. The house rules for the specific market decide these cases, and they should be read before betting.
Worked Example: An 8-Team Futures Market
Suppose a hypothetical league has eight teams listed to win the title at +250, +350, +450, +600, +800, +1000, +1500 and +2500. A $100 bet on the +600 team returns $700 if that team wins: $600 profit plus the $100 stake. If any of the other seven teams wins, the $100 is lost.
Now convert every price to an implied probability and add them up. The eight values are 28.57%, 22.22%, 18.18%, 14.29%, 11.11%, 9.09%, 6.25% and 3.85%. The sum is 113.56%, so the market is overpriced by 13.56 percentage points. The sportsbook’s theoretical hold is 1 − 1 ÷ 1.1356 = about 11.94%, which means that if bets were spread in proportion to the implied probabilities, the sportsbook would keep about $11.94 of every $100 wagered.
The Numbers That Matter: Hold and Fair Odds
To estimate what the prices would be without the margin, divide each implied probability by the total of 113.56%. The +600 team becomes 14.29% ÷ 1.1356 = 12.58%, which corresponds to fair odds of about +695. The posted +600 pays $95 less per $100 than the margin-free +695 would, and that gap is the cost of the bet.
| Posted odds | Implied probability | No-vig probability | Fair odds (approx.) |
|---|---|---|---|
| +250 | 28.57% | 25.16% | +297 |
| +350 | 22.22% | 19.57% | +411 |
| +450 | 18.18% | 16.01% | +525 |
| +600 | 14.29% | 12.58% | +695 |
| +800 | 11.11% | 9.78% | +922 |
| +1000 | 9.09% | 8.01% | +1149 |
| +1500 | 6.25% | 5.50% | +1717 |
| +2500 | 3.85% | 3.39% | +2853 |
A simple expected value check shows how evenly the cost is spread. Suppose, purely as an assumption, that the no-vig probabilities were the true chances. A $100 bet on any one team would then have an expected result of about -$11.94, since the same margin applies to every outcome. The cost is not in a single bad price but in the structure of the market. The explanation of the vig shows the same calculation on a two-way market, where the hold is far smaller.
Common Mistakes and Misconceptions
The most common mistake is judging a futures bet by its payout alone. A +2500 price looks exciting because it returns $2,600 on a $100 stake, but its implied probability is 3.85%, and the bet loses about 96 times out of 100. A big payout is the flip side of a small chance, not a bonus.
A second mistake is ignoring the margin because it is hidden. In a two-way bet at -110, the vig is easy to see. In an eight-outcome market, the margin is spread across every price, and the only way to see it is to add the implied probabilities together. A market that sums to 113.56% is far more expensive than one that sums to 104.76%.
A third mistake is forgetting that the money is tied up. A futures bet placed in autumn may not settle until spring, and the stake cannot be used for anything else in the meantime. Rules for withdrawn teams, ties and cancelled events vary by sportsbook, so a bettor should not assume that a refund will happen automatically.
Practical Tips for Reading Futures
Before betting, add up the implied probabilities of the whole market if the full list is available. The total shows how large the margin is, and it makes different markets comparable. A lower total means a smaller built-in cost, even when the individual prices look similar.
Check the settlement date, the tie rules and what happens if a team withdraws or the event is cancelled. Read the house rules for futures before placing the bet, because futures are the market where unusual outcomes are most likely to occur over a long horizon.
Set a budget before betting, never wager money needed for rent or bills, and keep a record of every bet. Legal age and the availability of sports betting differ by state. With a hold of this size, the average bettor loses over time, and a long-shot price does not change that.
Where to Go Next
Futures are easiest to understand after the basics of odds and implied probability. The break-even rate article explains how to turn a price into the win rate it requires, and the other prop bet types show how pricing differs from market to market.
A futures bet trades a long wait for a long price, and the market’s margin is paid on every outcome, whichever one is chosen. Seeing that margin clearly is the habit that makes any betting market easier to evaluate.
