FAQ
What is a middle bet?
A middle is when two sportsbooks offer non-overlapping lines on the same market. You bet OVER the lower number at one book and UNDER the higher number at another. If the final result lands in the gap between the two numbers, both bets win. If it lands outside, exactly one bet wins and you lose only the vig on the loser.
Are middles +EV?
Yes. Even with -110 vig on both legs, a 1-point middle on NBA totals (where final scores fall on every integer roughly equally near the line) pays out roughly 4-7% of the time, more than enough to cover the ~5% loss when both miss. Wider middles are higher EV.
How wide should a middle be to bet?
At least 0.5 points to be a real middle (not just price disagreement). 1+ point middles on NBA/MLB totals and 2+ point middles on NFL spreads are the historical sweet spot.
Why don't books close middles instantly?
Books move lines on the action they're seeing, not what other books are doing in real time. Slow movers (Caesars, Fanatics, regional books) frequently sit 0.5-1 point off DraftKings/FanDuel for 15-90 minutes pre-game. That's the middle window.
