Favorite-Longshot Bias in Futures Betting: Why Hold Hurts

Every season, sportsbooks post futures markets with 30 or more teams, and the long shots always look tempting. A 100-to-1 ticket on a team that could get hot sounds like a bargain. The reality is that favorite-longshot bias and high hold make long-shot futures the worst-value bets on most boards. Understanding why can save you hundreds of dollars over a season.

What Is Favorite-Longshot Bias?

Favorite-longshot bias is a well-documented pattern in betting markets: long shots are overbet relative to their real chances, and favorites are slightly underbet. The practical result is that the odds on long shots offer worse expected value than the odds on favorites.

The short answer for bettors: long-shot futures usually carry the biggest sportsbook margin. If a team's real chance is 1%, the book may price it as if the chance is 0.5% or lower, which means the payout is too small for the risk.

How Hold Works in Futures Markets

Hold is the sportsbook's built-in margin. In a two-outcome market at -110 each way, the hold is about 4.5%. In futures, the implied probabilities of all outcomes add up to well over 100%.

An Example With Made-Up Numbers

Imagine a six-team market with these American odds: +150, +250, +400, +800, +1500, +4000. Convert each to implied probability: 40%, 28.6%, 20%, 11.1%, 6.25%, 2.4%. Together they total about 108%. That excess of roughly 8 percentage points is the sportsbook's margin on the board.

In real futures markets with 30 teams, the overround is often much larger, and a lot of it is loaded onto the long shots. Our betting fundamentals page explains how to convert odds to implied probability.

Why Long Shots Carry More Hold

1. Public demand. Casual bettors love big payouts, so books can shade long shots without losing action.
2. Uncertainty. Estimating a 1% chance versus a 2% chance is hard, so books add a cushion.
3. Liability. A rare winner can cost a book a lot, so they limit exposure by shortening prices.
4. Low liquidity. Few bettors push long-shot prices back toward fair value.

The Math of a Long-Shot Ticket

Suppose a team is +5000, which implies a 1.96% chance. If you believe the real chance is 1.5%, the expected value of a $10 bet is:

• Win probability: 0.015
• Profit if win: $500
• Loss if lose: $10

Expected value = 0.015 x 500 - 0.985 x 10 = 7.50 - 9.85 = -$2.35. You lose about 23.5 cents per dollar. A -110 spread bet costs about 4.5 cents per dollar by comparison.

When Long Shots Can Make Sense

Not every long shot is a bad bet. Value exists when you have information that the market has not priced in.

• Early-season value. Before a rookie quarterback develops, or when a coaching change improves a roster.
• Injury returns. A star coming back from a long absence may be underpriced.
• Scheduling. A favorable schedule or draw can raise a team's real chances.
• Shopping. One sportsbook may have a number much better than the market. Use our US sports betting page to understand which operators are available in your state.

Even then, treat long shots as a small share of your bankroll. A 5% to 10% allocation is a common guideline for people who enjoy them, and it keeps losses manageable.

Better Ways to Use Futures

Bet Favorites When the Price Is Right

Favorites tend to be priced closer to fair value. A strong contender at +400 that you rate at 22% has positive expected value, even if it wins less often than you hope.

Hedge When the Position Is Strong

Futures tickets can gain value as the season goes on. Hedging lets you lock in profit or reduce risk. Not every hedge is smart, though, so compare the price to your expected value before acting.

Look at Alternative Markets

Division winners, conference winners, and win totals often have lower hold than outright championship markets. A 15-percentage-point win probability for a division is easier to estimate than a 1% title chance.

Comparing Sportsbooks

Futures hold differs between sportsbooks. DraftKings, FanDuel, BetMGM, and Caesars all price the same market a little differently. If you want to compare, read our DraftKings review and FanDuel review to see how each operator handles markets and promotions.

Practical Tips for Futures Bettors

1. Convert odds to implied probability and sum the board to see the hold.
2. Compare the same market across multiple books.
3. Limit long shots to a small fraction of your unit budget.
4. Remember that futures money is tied up for months.
5. Keep records of futures tickets alongside your other bets.

Responsible Betting Reminder

Futures can feel low-risk because the stakes are small, but the cost accumulates. Set a budget for the season and stick to it. If you need support, call 1-800-GAMBLER.

A Quick Worked Example With a Division Market

Consider a four-team division priced at +120, +200, +350, and +900. The implied probabilities are about 45.5%, 33.3%, 22.2%, and 10%, which total roughly 111%. The favorite carries a few points of margin, but the +900 team carries a larger share relative to its price, because its true chance may be closer to 7% or 8%. If you rate the favorite at 48%, the +120 ticket has positive expected value (0.48 x 1.20 minus 0.52 = +5.6 cents per dollar), while the +900 ticket likely does not.

This is why many experienced futures bettors build positions in the top half of the board and treat the bottom half as entertainment. They also compare closing prices over time to see whether their numbers beat the market, a habit that helps them learn whether they are really finding value or just guessing.

FAQ

What is favorite-longshot bias?

It is a market pattern in which long shots are overbet and favorites are underbet, so long shots offer worse value.

Why is hold higher on futures?

There are many outcomes, high uncertainty, and strong public demand for long shots, so books build in larger margins.

Are long-shot futures ever worth it?

They can be when you have a genuine information edge, but they should be a small slice of your bankroll.

How do I calculate hold on a futures market?
