How Our Arbitrage Bet Finder Works
We monitor lines from online sportsbooks to find arbitrage bets that are currently available. We check the odds every 30 seconds, so our free tool is always up to date.
You can find arbitrage bets on everything from today's games to games weeks into the future. If we detect it, we show it to you.
So how does it work?
When the odds of two sides of a bet add up to a positive number, we know we've found an arbitrage betting opportunity that will guarantee a profit if you bet both sides of it.
That's why you see Bet 1 and Bet 2 in the table above. You have to place both bets to guarantee yourself a profit.
How much should you bet? Check out our Arbitrage Calculator to figure out exactly what to wager on each side.
To use our arbitrage betting finder, simply check the cards above to see currently available arb bets based on our data. Here is an explanation of the columns:
- Event: The game, league, date, and time.
- Bet 1: The sportsbook, line, and odds of the first bet to place.
- Bet 2: The sportsbook, line, and odds of the second bet to place.
- ROI: A percentage showing your return on investment, assuming you bet the ideal amount on each side.
Pre-Game vs. Live Arbitrage Bets
Use the Pre-Game and Live toggles to switch between games that haven't started yet (pre-game) and games that are currently in progress (live).
There are often many more live arbitrage bets available than pre-game bets. Live arb opportunities, however, often disappear more quickly since lines and odds are constantly changing.
It's important to be careful when live arbitrage betting.
Since the lines change so quickly, they're much harder to get in. You risk only getting one side of the bet in, which likely leaves you with much more exposure and risk than you'd like.
P.S. If you find yourself in this situation, check out my article on what to do if you only get one side of an arbitrage bet in.

You can also use the Leagues dropdown to filter by league (such as NFL, NBA, CFB, CBB, MLB, NHL, Soccer, and more) and the State dropdown to find arb bets available at sportsbooks in your state.

How Arbitrage Betting Works, In General
Arbitrage betting—also known as arb betting, arbing or sure betting—is the most foolproof way of making a profit in sports betting.
Arbitrage betting works by simultaneously “backing” and “laying” wagers through two or more sportsbooks.
The idea is to bet on both sides of games or markets when there are pricing inconsistencies between different sportsbooks. If applied correctly, this concept guarantees a profit, regardless of the result.
You’ll know you found an arbitrage opportunity if the odds on the two sides of a market add up to a positive number (assuming you’re using American odds). You can also use arbitrage when taking advantage of free bets from sportsbooks.
While this sounds great, arbitrage opportunities can be hard to spot, and the guaranteed profit is often low compared to how much you have to wager. You have to put in a lot of work and research, but finding a true arbitrage opportunity is one of the only ways to guarantee yourself a profit when sports betting.
This is why using one of the best arbitrage bet finders, like Odds Assist, is so important. They do all of the heavy lifting. They monitor the odds, calculate if it's a true arb opportunity, and often even include on-screen calculators so you can instantly see how much you should be on each side.

Examples of Arbitrage Betting
If you can’t wrap your head around arbitrage betting, these examples might help:
Let’s say two sportsbooks offer different moneyline odds on the NFL matchup between the Buccaneers and Chiefs. At BetMGM Sportsbook, the following lines are presented:
- Tampa Bay Buccaneers +110
- Kansas City Chiefs -105
Meanwhile, the prices have moved in the opposite direction at FanDuel Sportsbook, which opens up the opportunity for arbitrage:
- Tampa Bay Buccaneers -105
- Kansas City Chiefs +110
This is a slam dunk. By betting on both the Buccaneers and the Chiefs at opposite books, you can lock in a profit. If you bet $100 on each side, no matter which team wins the game, you’re guaranteed a $210 return. This amounts to a $10 profit or 5% on the initial bet.
Now this isn’t going to make you rich overnight, but it’s guaranteed profit. Also, the more you bet when true arbitrage opportunities come up, the more you’ll make.
Now, let’s check an arbitrage betting example where you have to use different wagering amounts.
In a hypothetical MLB contest between the Dodgers and the Red Sox, BetRivers has the Dodgers as the favorite:
- Los Angeles Dodgers -165
- Boston Red Sox +155
After shopping around, you discover that Caesars Sportsbook has more favorable MLB odds on the Red Sox.
- Los Angeles Dodgers -195
- Boston Red Sox +175
Like in the first example, you have to bet on both teams to cover all possible outcomes. Only this time, you won’t wager the same amount on both sides.
- A successful $100 bet on the Dodgers at BetRivers returns $161: $100 stake plus $61 profit
- A successful $60 bet on the Red Sox at Caesars returns $165: $60 stake plus $105 profit
The total amount of wagers for this game will be $160. If the Dodgers win, you’re up $1. In the case of a Red Sox win, you’ll net a $11 profit. Admittedly, these aren’t life-changing returns, but grinding out numerous smaller wins can add up over time. Best of all—it’s completely risk-free.
Note: Assuming you place $100 on the Dodgers, the ideal bet on the Red Sox in the above scenario would be $58.40. This would return a $2.20 profit regardless of the outcome.
For this method to work, you need to figure out how much cash you need to bet on each side to guarantee yourself a profit. You can use our arbitrage calculator to determine the ideal wagering amounts.
How to Find Arbitrage Betting Opportunities
The success of your arbitrage bets is contingent on identifying favorable pricing discrepancies, which takes time and effort.
You have to monitor the market continuously and scan the odds and game lines of multiple sportsbooks.
Furthermore, you need to act fast and place your wagers as soon as the opportunity presents itself; otherwise, it may be gone for good.
That's why using betting tools that find free arbitrage bets can save you a lot of time and help you find more opportunities to take advantage of.
Here are some ways that may help you with this often-difficult process.
Arbitrage Betting by Comparing Sportsbooks
The most straightforward arbing approach is shopping lines and odds—comparing the lines and odds of multiple sportsbooks for the same markets.
If the odds on the opposing sides of a 2-way market are positive when added together, then you’ve found yourself an arb betting opportunity. Note that you also have to factor in the optimal wagering amounts for each bet to secure profits.
Let’s consider this NFL game between the Eagles and Cowboys:
- DraftKings has the Cowboys listed at -140 odds
- FanDuel has the Eagles at +150.
The sum of these prices is +10, which indicates an arb opportunity. If we bet $100 on the Eagles, we’d get a $250 return ($150 profit + $100 wagered) on their win.
Simultaneously, we need to put $145.83 on the Cowboys to guarantee a profit of $4.17, regardless of how the game breaks.
Doing this manually is very difficult, which is why we created the free arb finder tool above. We scan sportsbook lines every minute to find arbitrage bets that are currently available.
Why spend hours looking for a single arb bet when you can just use our arbitrage betting software above to find them automatically?!?!
Arbitrage Betting With Line Movement
This refers to betting a side early and then waiting for the line to move in your favor. The fluctuations in lines can happen due to various factors, including injury and weather reports, last-minute roster changes, or additional betting action coming in on one side.
Let’s say you bet the Bucks to beat the Lakers at +300 as soon as the odds get released. Lebron James gets ruled out a few hours later due to an injury, and the line moves to Bucks -110. This opens up a chance for arbitrage, as you could bet the Lakers to guarantee yourself a profit.
We have a Recently Moved Lines tool on Odds Assist Pro that helps you identify these opportunities. You can see lines that moved significantly in the past hour and find which books are lagging behind in updating their odds.
Arbitrage Betting With Odds Boosts
You can also make arbitrage plays by using odds boosts offered by most online sportsbooks. This is when a betting site offers special promotional odds for a specific market.
As with line shopping, it’s recommended that you sign up with multiple sportsbooks to make sure that you don’t miss out on a potentially lucrative opportunity.
Arbitrage Betting With Free Bets
If a sportsbook gives you a free bet or risk-free bet, you can place that on one side of a two-way market and place a real money bet on the other side to guarantee yourself a profit.
