Demystifying 1/1 Betting Odds: A Thorough Guide for Beginners
Hey there! Terry Williams here, back again to dive deep on another hot topic for aspiring sports bettors. If you‘ve been looking into wagering on your favorite games and events, odds are you‘ve seen the fraction "1/1" used for certain betting lines. As a seasoned data analyst and contributor for 33rdsquare in the world of sports tech and statistics, I‘m going to break down exactly what 1/1 odds mean and how they work.
Stick with me, and you‘ll be a pro in no time!
Odds Refresher
First, a quick refresher on betting odds for those new to sports gambling: Odds represent the likelihood of an outcome occurring in a sports match or any probability-based event. Bookmakers analyze stats, injuries, and other factors to determine the chance of each competitor winning.
For any game, there will be lines set for outcomes like:
- Team A to win
- Team B to win
- The point total scoring over/under a set number
Bookies convert these probabilities into formats like:
- Fractions (e.g. 4/1)
- Decimals (e.g 1.80)
- Moneyline (e.g. -150)
The odds also indicate the potential payout on a winning bet. Now let‘s see how 1/1 odds fit into the picture!
Introducing 1/1 Odds
In fractional odds, you‘ll usually see two numbers separated by a slash like 9/2 or 5/1. But occasionally, bookies will set odds for an event at 1/1.
This means the bookmaker believes the two outcomes have an equal, 50/50 chance of happening.
For example:
- Coin landing on heads or tails
- Tennis player winning or losing the 1st set
- Football team kicking off the overtime period
Any situation with just two results that are deemed equally likely makes for prime 1/1 odds. Of course, the bookies‘ assessments aren‘t perfect, which is how savvy bettors find an edge!
Key Facts on 1/1 Odds
Here are some key things to know about 1/1 fractional odds:
- They can also be expressed as "evens", "even money" or 2.00 in decimal odds.
- The 2 possible outcomes have an implied probability of 50% each.
- Payout is equal to the stake amount, so double your money.
With most odds formats, you‘ll need to calculate payouts using tricky formulas. But with 1/1 odds, if you bet $10 and win you get back…$20! Let‘s look at some examples:
| Stake | Odds | Payout |
|---|---|---|
| $10 | 1/1 | $20 |
| $50 | 1/1 | $100 |
| $125 | 1/1 | $250 |
Easy enough so far? Now for some more in-depth math and analysis!
Calculating Returns on 1/1 Bets
While the payouts are straightforward, let‘s walk through the formulas used for other odds:
Fractional: Stake x (Numerator / Denominator) + Stake
A $75 bet at 1/1 fractional odds:
75 x (1/1) + 75 = $150
Decimal: Stake x Odds
A $20 bet at 2.00 decimal odds:
20 x 2.00 = $40
As you can see, with 1/1 and 2.00 odds these both reduce nicely to give you double your money back.
Converting 1/1 Odds Between Formats
Being able to quickly convert between fractional, decimal, and moneyline odds is an invaluable skill for bettors. Here‘s how to go back and forth with 1/1 specifically:
- Fractional 1/1 = Decimal 2.00
- Decimal 2.00 = Fractional 1/1
- Fractional 1/1 = Moneyline +100
- Moneyline +100 = Fractional 1/1
Get familiar with these conversions, as you‘ll often find discrepancies between formats that can reveal smart bets.
Average Vig on 1/1 Odds
One important thing to note is the bookmaker‘s edge, known as the vigorish or "vig". This refers to how they build in a ~5% margin to ensure profit on all bets.
With most odds, they just adjust the payout amount down slightly. But for 1/1 odds, lowering the 2x payout would change the odds.
So with 1/1 odds, the bookies adjust the implied probability from 50% to about 47% instead.
This means if the true odds are 1/1 (50%), they may actually offer about 0.95/1.05 or 1.90/1.90 (47%).
While barely noticeable, this vig adds up over thousands of bets and guarantees the house always wins!
Examples of 1/1 Betting Markets
Now that you‘ve got the basics down, here are some real-world examples of where you‘ll see 1/1 odds:
-
Coin flips: Betting heads or tails on an actual coin toss or simulated digital coin flip. Equal chance of either.
-
Awards shows: Betting whether the host will appear on stage first from screen left or right. Pure 50/50 guess.
-
Tennis: Betting on a set going to deuce (tied 6-6) or not. Happens nearly half the time.
-
Politics: Betting on seat totals for parties in an election. Toss-up with no clear favorite.
-
Entertainment: Betting on celebrity baby names or genders. No way to predict either option.
Any topic with two clear outcomes and no obvious favorite lends itself perfectly to 1/1 odds.
Hedging Bets with 1/1 Odds
An interesting strategy with 1/1 odds is "hedging" your bet. This involves placing wagers on BOTH outcomes to guarantee a profit.
Let‘s say you bet $110 on a coin landing heads at 1.90 odds, and $110 on tails also at 1.90.
- Heads win = $110 x 1.90 = $209
- Tails win = $110 x 1.90 = $209
This locks in $9 profit after getting your $220 in stakes back. Hedging works with any odds but is especially effective with near even money favorites and underdogs.
Historical 1/1 Derby Odds and Results
To put it in context, let‘s look at some real 1/1 odds from the world-famous Kentucky Derby horse race:
| Year | Horse | Odds | Result |
|---|---|---|---|
| 2019 | Game Winner | 9/2 | 2nd |
| 2018 | Justify | 1/1 | Won |
| 2017 | Classic Empire | 6/1 | 4th |
| 2016 | Nyquist | 11/10 | 3rd |
| 2015 | Dortmund | 4/1 | 3rd |
As you can see, Justify went off at 1/1 odds in 2018 and ended up winning the race. This remains one of the only times a horse started as an even money favorite (implied 50% chance) and went on to victory.
So if you‘re ever lucky enough to land a 1/1 bet with true odds and no vig, make sure to let it ride!
Should You Place Bets at 1/1 Odds?
While appealing for their simplicity, consistently winning money on random 1/1 odds bets is unlikely long-term. The bookmaker‘s ~5% vig builds in a disadvantage off the bat.
However, 1/1 odds can provide opportunities for smart bettors in certain situations:
Spotting Mismatching Odds
If you determine through research that the true odds are closer to 60/40 in a matchup, getting 1/1 odds would provide great value.
Arbitrage Betting
You can secure guaranteed profits by betting both sides of 1/1 odds at different books.
Hedging and Reduced Risk
Hedging 1/1 spots as part of an overall portfolio management strategy limits potential losses.
So while recreational bettors should stick to betting small for fun at 1/1, pros have options to gain an edge in the right spots.
