As a sports bettor and stats geek, I‘m always considering the odds when analyzing potential wagers. And 10-1 odds come up regularly representing long shots across different sports and bet types.
But what do odds like 10-1 or 10/1 really mean? And is a bet actually worth it when the probability of winning is so low?
These are important questions for bettors looking to make informed wagering decisions. So in this guide, I‘ll provide an in-depth explanation of 10-1 odds, when you might bet them, and some memorable cases where a 10-1 long shot shockingly paid off.
Defining 10-1, 10/1, or "Ten to One" Odds
First, let‘s start with a clear definition of 10-1 odds in gambling:
- 10-1 odds mean an event has around a 1 in 10 chance (9.1% probability) of occurring.
- For every 11 possible outcomes, the favored result will happen 1 time and not happen 10 times.
- Other formats for 10-1 odds include fractional 10/1 and decimal 11.00.
- In American moneyline format, 10-1 is listed as +1000 odds.
So across different sportsbooks and betting sites, you may see 10-1, 10/1, 11.00, or +1000 all representing the same thing – a probability of 9.09% implied by the odds.
To summarize, 10-1 odds indicate an unlikely long shot pick that is expected to lose most of the time. Out of 11 instances, it would only win once on average.
Here‘s a comparison table showing equivalent odds formats for 10-1 odds:
| Odds Format | Odds | Probability |
|---|---|---|
| Fractional | 10/1 | 9.09% |
| Decimal | 11.00 | 9.09% |
| American | +1000 | 9.09% |
Why 10-1 Odds Represent a Low Probability
You‘ll notice that as the first number of the fractional odds increases, the probability goes down.
For example:
- 1-1 odds = 50% probability since 1 outcome will happen and 1 will not. Even odds.
- 2-1 odds = 33.3% probability as the event will occur 1 out of 3 times.
- 5-1 odds = 16.7% probability as the event occurs 1 out of 6 times.
- 10-1 odds = 9.1% probability with only 1 expected occurrence out of 11.
So odds of 10-1 or higher start to represent very low percentage outcomes – the real long shots.
Think of it this way – would you expect to win a 10-1 bet most of the time? Of course not, because the implied probability is only around 1 in 10 that it hits.
Now compare 10-1 to much shorter odds like 1-2 (implied probability of 66.7%) and it‘s clear that the higher the first number in fractional odds, the less likely that outcome is probable.
Betting Contexts Where You‘ll See 10-1 Odds
While a probability of 9.1% represents an unlikely event, you‘ll actually find plenty of betting opportunities at 10-1 odds across different sports and gambling formats.
Here are some examples of when you might see 10-1 odds:
- A major underdog in a football or basketball game.
- Long shot horses in horse racing events like the Kentucky Derby.
- Big payouts in casino games like roulette or blackjack side bets.
- A betting prop in a combat sport for a likely outcome but still an underdog.
- Jackpot or bonus slots with advertised "10-1" payouts.
You get the idea – sportsbooks and casinos use 10-1 odds to entice bettors to take a chance on low percentage outcomes.
The appeal is that while your probability of losing the bet is high, the potential payout if you win is very rewarding compared to your original wager.
After all, who wouldn‘t want to turn $10 into $110 if that 10-1 long shot actually did pull off the upset?
Next, let‘s look at the payouts and betting strategy around wagers placed at 10-1 odds.
Payouts and Strategy When Betting 10-1 Odds
The payout on a winning bet placed at 10-1 odds is easy to calculate:
For a $10 bet at 10-1 odds, the payout is $110 – your $100 profit plus return of your $10 initial bet.
The higher the odds, the higher the payout on a winning wager. So 20-1 odds would pay $210 on a $10 bet, 50-1 odds pay $510, etc.
However, the catch is that even at 10-1, your bet has just a 9.1% chance statistically to win. So what should your betting strategy be with long odds like this?
Here are a few tips for effectively betting 10-1 or higher odds:
- Bet small relative to your overall bankroll, as it‘s still an unlikely result.
- Don‘t automatically assume high odds means it‘s a good bet. Look for value.
- Combine a 10-1 long shot in a parlay to increase the payout odds significantly.
- Shop around between sportsbooks for the best price on your 10-1 pick. An extra point or two matters.
- Evaluate if the high reward justifies the risk – only make the bet if you‘re comfortable with the downside.
- Stick to your structured bankroll rules – never chase losses by reckless betting.
The key is being selective and calculating when taking on a high odds bet – have a rationale for why it‘s worth the risk. Never bet randomly on every underdog you see at 10-1.
Memorable Long Shot Winners at 10-1 Odds
While upsets are rare, we‘ve seen some famous cases where a long shot at 10-1 defied the odds and came out victorious.
Here are a few of the most remarkable and surprising 10-1 underdog winners in major sports:
-
#16 UMBC beating #1 Virginia in the 2018 March Madness college basketball tournament. Virginia was the top overall seed and UMBC didn‘t even win their conference.
-
The St. Louis Blues overcoming 10-1 pre-season odds to win the 2019 Stanley Cup Finals over the favored Boston Bruins hockey team.
-
Buster Douglas knocking out Mike Tyson in 1990 as a 42-1 underdog. But his odds to win by KO were closer to 10-1 before the fight.
-
The New York Giants defeating the 18-0 New England Patriots as 12-1 underdogs in Super Bowl XLII. It‘s considered one of the biggest upsets in NFL history.
-
Leicester City had pre-season odds as high as 5,000-1 to win the English Premier League in 2016. But by season‘s end, 10-1 odds to take the title would not have been mis-priced.
Another betting strategy with long shots is looking for opportunities where the odds to just place or finish top 3 may be closer to 10-1, even if the odds to win are much higher. This was the case with some of the examples above.
But key is identifying if those 10-1 odds actually offer value or not. Just because the payout is alluring does not mean it‘s a smart wager in every case.
How Sportsbooks Set the Betting Odds and Lines
To wrap up this deep dive on 10-1 odds, it helps to understand how sportsbooks actually come up with the odds in the first place.
Setting the right betting line is crucial for bookmakers to balance risk and generate equal betting action on both sides. Their aim is to create a line where the public money will be split fairly evenly.
To accomplish this, bookmakers estimate the implied probability for each participant to win based on related data and other factors:
- Team‘s record, talent, and performance metrics
- Player injuries or absences
- Home field advantage
- Weather forecasts
- Situational context like rivalries
- How the betting public is wagering early on
They use this information to project a realistic probability of each outcome. From there, the odds are set to attract wagering volume on both sides.
For big underdogs with a low win probability, like 10% or less, they‘ll typically see odds in the 10-1 or higher range.
Odds and probabilities move leading up to an event as more bets are placed and bookmakers adjust to attract more balanced action. So 10-1 may shift to 9-1 or 12-1 on the same team as betting patterns emerge.
It‘s why line shopping for the best odds is so important. A single point or two of difference on a 10-1 bet makes a big impact on the payout.
Final Thoughts on 10-1 Long Shot Odds
While risky, betting on potential 10-1 upsets and long shots is an intriguing part of sports betting. The lure of a large payout is addicting if you manage to beat the odds.
But restraint and smart bankroll management are crucial. Over the long run, the sportsbook wins on most 10-1 wagers.
By fully understanding what 10-1 odds represent in terms of probability, payout, and implied risk, you can make more informed betting decisions.
My goal is to always find that perfect balance – taking enough calculated risks to make betting fun and rewarding, but not so many that I‘m just recklessly gambling on every underdog without reason.
For fellow sports bettors out there, hopefully this deep dive on 10-1 odds and long shot probability gives you something to consider the next time you see an intriguing betting opportunity listed at "10 to 1".
