Arbitrage bet finders

This tool, as the (very creative) name implies, helps you find arbitrage bets.

If you don't know what arbitrage bets are, I'll give you the quick rundown: these are markets where sportsbooks have such different odds that you can bet both sides and guarantee yourself a profit regardless of who wins.

Imagine if you're betting on a coin flip but both heads and tails pay out $1.10 for every $1 bet. You could simply bet on both sides and you'll turn a profit no matter what.

That's what arbitrage bets are; now I'm going to show you how to find them with OA Pro (it's super easy):

Arbitrage bet finder tool interface

Each card you see shows an event that currently has an arbitrage betting opportunity available.

Some cards, like in this example, will have multiple rows, which means multiple arbs are available for the event. Most often, this will be for the same bets (Over 7 and Under) but with one different sportsbook (BetMGM & Caesars).

1) Bets & sportsbooks

This section shows which two sportsbooks you need to bet on to lock in the arbitrage opportunity and which specific bets you have to make.

In the first case, you will be placing two bets:

  • Over 7 in Brewers @ Pirates at +105 odds at BetMGM
  • Under 7 in Brewers @ Pirates at +100 odds at Caesars

2) Total wager amount & bet sizes

First, enter how much you want to wager across both bets in the Total Wager column.

Once you do this, the Bet Sizes section will update to show how much you should be at each sportsbook and your total payout.

Make sure that the odds reflect what you're seeing on the sportsbook app/site.

If the odds are different for some reason, you can quickly tell if the arb opportunity is still present by adding the odds of each side of the bet together.

Using the example above, we would add +105 (O7 on BetMGM) and +100 (U7 on Caesars) to get +5.

Since the sum is a positive number, we know we will profit no matter what, as long as we bet the right amounts.

3) Return on Investment (ROI)

This section simply shows how much of your total bet amount you will profit based on the current odds.

While we include all arbs that guarantee a profit, many users choose to only spend time on those that result in an ROI of 1% to 5% or more.

4) Filters

Here, you can:

  • League – Choose which league you want to show arb bets for.
  • Market – Specify what types of markets (spread, moneyline, total, etc.) you want to see arb bets for.
  • Period – Choose a specific game period you want to see bets for (full-time, first half, etc.)
  • Sportsbooks – Check which sportsbooks you want to be included so you don't waste your time looking at opportunities on books you don't use.

5) Automatic refresh

Keeping this toggled on (which is the default) will update the screen as soon as we detect a new arb or an arb is no longer available.

I recommend just leaving this checked. There's not really much of a reason not to.

6) Live arbitrage bets view

Here you can see arbs for games that are currently in progress. These often have higher ROI due to the volatility of live odds, but are harder to lock in since the odds change so frequently.
