A middle bet is when there is a chance to bet two sides of a bet and win both if the result ends up on a certain spread or point total.
For example, say FanDuel has the Eagles/Giants Total (Over/Under) at 48.5, but DraftKings has the Total at 46.
You could bet Under 48.5 at FanDuel and Over 46 at DraftKings. If the total ends up at 47 or 48, you would win both bets.
That's a middle bet! The spreads/totals differ enough that there is a middle section with overlapping numbers.
Let's take a look at the tool to help illustrate further:
Much like the +EV and arb tools, our middle tool has a single row for each event that has middle opportunities.
In the first row, we see a middle between the Red and Twins, with both BetMGM and BetPARX offering one of the sides at +1.5.
We could bet the Reds +1.5 at BetMGM and the Twins +1.5 at BetPARX. If the game ends with either team winning by 1, you would win both sides of the bet.
It's not as simple as taking every middle opportunity available like with arb and +EV bets, however. You need to consider the difference between the lines and the odds.
We'll go over odds next, but quickly, when I say "the difference between the lines," I mean how big that middle section is, which you can see in the Middle Gap column.
In this example, we have 3 points in the middle. The bigger the middle section, the greater the chance that it hits.
Note that for sports with lower scores (hockey, baseball, soccer, etc.), points in the middle are more valuable than in higher-scoring sports like football and basketball.
This section simply shows how much you would win if the middle hits (Max Profit) and how much you could lose if the middle doesn't hit (Max Loss).
In the case of max loss, one of the bets has to hit, so you'll always be winning at least one side of the bet, though it may not make up for the amount you would lose on the other side of the bet.
Same filters as the other tools: League, Market, Period, and Sportsbooks.
Keeping this toggled on (which is the default) will update the screen as soon as we detect a new middle opportunity or when one is no longer available.
