Short Odds vs Long Odds: Risk, Reward, and When to Use Each
Every bet sits somewhere on the risk-reward spectrum. Understanding where it sits, and more importantly, where you should sit, is fundamental to profitable betting.
This guide explains short odds versus long odds, when each makes sense, and why the most profitable bettors often ignore which one feels safer.
Defining Short Odds and Long Odds
Short odds are prices close to 1.0 in decimal format. Examples: 1.20, 1.33, 1.50, 1.80.
These odds imply the outcome is likely. Your profit is small relative to your stake. A £10 bet at 1.50 odds profits only £5. But the outcome is expected to happen more often than not.
Long odds are prices far from 1.0 in decimal format. Examples: 3.0, 5.0, 10.0, 25.0.
These odds imply the outcome is unlikely. Your profit is large relative to your stake. A £10 bet at 5.0 odds profits £40. But the outcome is expected to happen less often.
Here's the key principle: the closer odds are to 1.0, the more likely the outcome. The further from 1.0, the less likely. The difference in stake and profit reflects this.
A £10 bet at 1.20 odds profits £2. A £10 bet at 10.0 odds profits £90. But the 1.20 outcome is expected to happen about 83% of the time, while the 10.0 outcome is expected to happen about 10% of the time.
The Risk-Reward Trade-Off
This is the essence of betting. You can't have both low risk and high reward.
Short odds (1.20 to 1.80):
- Low risk. The outcome is expected to happen.
- Low reward. Your profit is small.
Long odds (3.0 to 50.0):
- High risk. The outcome is not expected to happen.
- High reward. Your profit is large.
Many beginners think "I'll just bet on the favourite to keep it safe." They place bets at 1.30, 1.40, 1.50 odds on strong favourites. They feel safe because the outcome is likely.
But here's the trap. A 1.30 favourite wins 77% of the time. But 77% isn't 100%. Over 100 such bets, you're wrong 23 times. You profit £3 each time you win (on a £10 stake), but lose £10 each time you're wrong. The maths doesn't work.
You need either:
- To win more than the odds suggest you should (find genuine value in the odds)
- To have access to better information than the bookmaker
- To stop betting on even odds (which most people never do)
The belief that "short odds are safer so I'll make money" is a common losing strategy.
When Short Odds Make Sense
There are legitimate times to back short odds.
Building larger accumulators: If you have three selections you like at 1.50, 1.40, and 1.80 odds, combining them creates 1.50 × 1.40 × 1.80 = 3.78 overall odds. This can be sensible. You're building a longer odds, and if you believe all three selections have value (or are very likely), the combined bet makes sense.
Bank bets in accumulators: A "bank bet" means one selection appears in every combination. Professional accumulators often bank a strong favourite at short odds and combine it with less certain selections at longer odds. This balances the bet.
When you have information advantage: If you know something the bookmaker doesn't (which is rare), short odds might still be profitable. For instance, if you know an injury isn't as bad as reported and a 1.50 favourite is actually closer to a 1.30 favourite, you've found value.
Building a streak in a specific market: Some bettors identify a market where they consistently beat the bookmaker. They might exclusively play short odds in that market because their edge is reliable. This requires significant experience and data.
Professional arbitrage: Some professionals look for price discrepancies across bookmakers where you can back both sides profitably. This sometimes involves short odds.
For most beginners, though, consistently backing short odds is a losing strategy. The money isn't in betting on likely outcomes. It's in finding outcomes where the odds are longer than they should be.
When Long Odds Offer Value
This is where serious money is made.
If you can identify outcomes where:
True probability > Implied probability (from the odds)
You've found value, regardless of the odds.
For example:
A midfielder is 8.0 odds (implying about 12.5% chance) to score in a match. You've analysed the team's pattern play, ball progression maps, and his recent form. You believe he's actually 15% likely to score.
The odds say 12.5%, you say 15%. The 8.0 odds are longer than they should be. This is value.
Over 100 such bets, your 15% accuracy would profit significantly while the bookmaker's 12.5% pricing would lose money.
This is the real advantage professionals have. Not that they bet on long odds just because they're exciting. But that they find long odds where the bookmaker has underpriced the outcome.
Here's another example:
A 5.0 outsider in a football match. The bookmaker thinks it's 20% likely to win. You think it's 25% likely (better recent form, recent results, head-to-head history). The true probability is close to yours, and the bookmaker's 5.0 odds underestimate it.
A £10 bet at 5.0 odds that wins £40 is excellent value if the outcome is 25% likely. You're not betting on 5.0 odds just because they're exciting. You're betting because they're longer than they should be.
This is the essential skill: spotting outcomes where true probability and implied probability diverge, then acting on the long odds when they favour you.
The Psychological Trap of Only Backing Short Odds
Most recreational bettors develop a comfort zone with short odds. They feel safe, feel like they're winning more often.
But here's the reality:
Short odds pay so little that after bookmaker margins, small losing streaks are devastating.
You place 20 bets at 1.40 odds on what you think are strong selections. You think "1.40 odds, these are likely, I should win most of them."
You win 14 out of 20. That's 70%. You think you've done well.
Total profit: 14 × (£10 at 1.40 = £14) = £196 Total loss: 6 × £10 = £60 Net profit: £196 - £60 = £136
Winning 70% of 1.40 odds bets is profitable. But 70% is exceptional — most bettors are nowhere near that accurate.
More realistically:
You place 50 bets at 1.40 odds. You win 32 out of 50. That's 64%.
Total profit: 32 × £4 (profit on £10 stake at 1.40) = £128 Total loss: 18 × £10 = £180 Net profit: -£52
You've lost money despite winning 64% of your bets. That's the margin problem.
Now compare to longer odds:
You place 50 bets at 4.0 odds. You win 15 out of 50. That's 30%.
Total profit: 15 × £30 (profit on £10 stake at 4.0) = £450 Total loss: 35 × £10 = £350 Net profit: +£100
You've made profit despite winning only 30%. That's the value principle.
This is why professionals don't ignore longer odds. They don't just back them for excitement. They seek them out because longer odds can be more profitable if the probability assessment is correct.
Short Odds in Singles vs Accumulators
A single bet is one selection. An accumulator combines multiple bets.
Short odds in singles: Generally unprofitable long-term because the returns don't justify the margin.
Short odds in accumulators: Often sensible because you're multiplying them by other odds, creating a longer overall price that might be worthwhile.
Example single:
- Bet £10 at 1.50 odds on a favourite
- Win £15 (profit £5)
- This is low reward for the risk
Example accumulator:
- Bet £10 on three selections at 1.50, 1.40, 1.80
- Combined odds: 1.50 × 1.40 × 1.80 = 3.78
- Win £37.80 (profit £27.80)
- Much better reward
The accumulator transforms short individual odds into longer combined odds. This can work if you believe all selections have value. But it's riskier because all three must win.
How Odds Movement Reveals Value
When odds move, it often signals where the smart money is going.
If a 3.0 outsider shortens to 2.5, sharp money (professional money) is backing it. This suggests value was identified.
Conversely, if a 1.50 favourite drifts to 1.60, sharp money is moving away. They might see it as overpriced.
As a recreational bettor, you don't always have the information or timing to follow sharp movements. But recognising them helps you understand value.
If you were about to bet on that 1.50 favourite and you see it drift to 1.60, that drift is a warning sign. Smart money has moved away. Should you bet? Maybe not.
If you identify a 4.0 long shot and see it tighten to 3.5, are you too late? Not necessarily. Depends on your own assessment. But the movement tells you something.
Short Odds on Strong Favourites Can Be Traps
The strongest favourites often offer the worst value.
A team at 1.20 odds to beat a much weaker team is almost certain to win. But 1.20 odds mean you profit only £2 on a £10 stake. The bookmaker has priced the certainty correctly.
For you to profit, you need either:
- To be more confident than 83% (the implied probability of 1.20), which is hard because the bookmaker's models are sophisticated
- To find an edge (better information), which is rare against strong favourites
- To get lucky
Most people just bet the favourite and hope. That's not a strategy.
This is why some professionals deliberately avoid the shortest odds. Not because short odds are bad, but because genuine value is rare at those prices. The bookmaker has priced likely outcomes correctly.
When Long Odds Are Overpriced Traps
Just as short odds on strong favourites can be undervalued, long odds on weak outsiders can be overpriced.
A team at 10.0 odds is expected to win 10% of the time. But do you believe they're actually 10% to win? Or are they 5% likely?
If they're 5% likely, then 10.0 odds are overpriced. Don't bet. The odds aren't offering value just because they're long.
This is the mistake some bettors make. They see 10.0 odds, think "great returns if it hits," and bet without questioning whether the outcome is actually 10% likely.
Long odds are only valuable if you believe the true probability is higher than the odds suggest.
Combining Short and Long Odds Strategically
Professional bettors mix short and long odds based on value, not comfort.
They might place:
- Three selections at short odds (1.50, 1.40, 1.35) because they've identified genuine value in likely outcomes
- One selection at long odds (5.0) because they've found an underpriced outsider
- A combination of both in accumulator bets
The selection isn't based on "I like short odds" or "I like long odds." It's based on "These odds offer value relative to my probability assessment."
This is the mindset shift that separates serious bettors from casual ones. You don't have a preference for short or long odds. You have a preference for value.
The Bankroll Impact of Short vs Long Odds
Your bankroll (total betting budget) is affected differently by short and long odds.
Short odds preserve bankroll. You're not losing big amounts when you're wrong (£10 loss on each wrong bet). But you're also not gaining much when you're right (£5 profit on each right bet at 1.50).
Long odds have wider variance. You're losing bigger amounts when you're wrong (£10 loss). But when you're right, you're gaining a lot (£30+ profit at 4.0 odds).
For bankroll growth, you need to win enough at long odds to overcome the losses. This requires better accuracy or better value identification.
Many bettors prefer the steadiness of short odds (less bankroll fluctuation) but forget that steady small wins don't overcome bookmaker margins. You need occasional bigger wins to grow your bankroll.
Real Examples from Football Markets
Example 1: Strong Favourite
Chelsea playing a bottom-of-the-table team at home. Chelsea odds 1.40.
Implied probability: 71%.
Is Chelsea 71% likely to win? Maybe. Maybe Chelsea is actually 75% likely. If so, 1.40 is fair or slightly underpriced. Skip it unless you have exceptional confidence.
Example 2: Evenly Matched Teams
Two mid-table teams. Draw odds 3.40.
Implied probability: 29%.
Draws happen 25-26% of the time. At 3.40, the bookmaker is pricing the draw at 29%. This is relatively fair. You'd need to believe draws are more likely than 29% to bet, which is against the average.
Example 3: Underdog with Positive Factors
A team usually loses, but they're at home, their main striker is back from injury, and they're playing the worst-form team. Odds 5.0 to win.
Implied probability: 20%.
Is this team 20% likely to win under these conditions? You've identified specific factors that might push their true probability to 25% or 30%. At 5.0, you've found value.
In Summary
- Short odds (1.20 to 1.80) mean lower risk and lower reward.
- Long odds (3.0 and up) mean higher risk and higher reward.
- The choice between them shouldn't be based on which feels safer.
- It should be based on where you've found value.
- Most recreational bettors lose money by exclusively backing short odds on likely outcomes.
- The returns don't justify the bookmaker margins.
- Professionals seek out situations where true probability exceeds implied probability, which often happens at longer odds but can happen at any price.
- The key is assessment.
- Calculate your own probability.
- Compare it to the odds.
- If your probability is higher, that's value.
- If the value exists at long odds, take them.
- If it exists at short odds, take those instead.
- Don't let odds prices dictate your strategy.
- Let your probability assessments dictate your strategy.
- The odds are just a tool to measure value.
Frequently Asked Questions
Is it better to bet more money on short odds or long odds?
Stake size should be based on confidence and bankroll, not odds length. If you're confident in a selection, your stake reflects that confidence. The odds themselves shouldn't determine stake size. A long odds bet you're very confident in might deserve a bigger stake than a short odds bet you're less sure of.
Can I become profitable betting only on short odds?
Theoretically yes, but practically very difficult. You'd need to win significantly more than the odds suggest you should, which requires exceptional accuracy or information advantage. Most people are better served exploring a mix of odds and finding value across the spectrum.
Why do bookmakers make the biggest odds shorter than most bettors expect?
Bookmakers price odds based on algorithms, money flow, and their profit margin. If an outcome is genuinely 70% likely, they might price it at 1.50, which implies 67%. They've built in their margin and left room for profit. This is why direct betting against the favourite is often value. Bookmakers overprice the most popular selections.
Should I follow steam moves from short odds to long odds?
Only if you understand why the steam is happening. A sudden shortening from 5.0 to 3.0 might signal sharp money has identified information you don't have. Or it might be a false signal. Don't just follow the movement. Understand the reasoning.
Are long odds at betting exchanges better than at bookmakers?
Sometimes. Betting exchanges have lower commissions than traditional bookmakers' margins, but the odds are set by other bettors, not a central bookmaker. This means you can sometimes find better value, but you can also find worse value if you're not careful. Shop around.
What's the difference between short odds and a heavy favourite?
Short odds is the price (like 1.30). A heavy favourite is the market description (the team expected to win). A heavy favourite might be 1.20, 1.30, 1.40 depending on how dominant they are. All are short odds, but some favourites are heavier (shorter odds) than others.
