Sometimes two sportsbooks create a window where you can win both sides.
If the final score lands in between the two bets, you’ll win both! If it doesn’t, you’ll break even from the side that wins.
Hitting the middle is rare but when it hits, there’s no better feeling!
Start small or go all-in—we've got the perfect plan to fit your needs.

Middle betting means betting both sides of a spread or total at different numbers, so a final result that lands between them wins both bets. For example, Over 44.5 at one sportsbook and Under 47.5 at another wins twice on a total of 45, 46 or 47.
AVO scans spreads and totals across 70+ sportsbooks and flags every game where two books have moved far enough apart to open a window between their lines. Each middle shows both bets, the size of the window and what to stake on each side.
One bet wins and the other loses, so you usually give back a small amount, roughly the sportsbook's margin on the two bets. When the prices are good enough you can break even or come out slightly ahead. The occasional middle that hits pays both bets.
NFL spreads and totals are the classic market because so many games land on key numbers like 3 and 7. Basketball totals and spreads move a lot during the week and in-game, so they open middles often too.
An arbitrage bet locks in a small profit whatever happens. A middle accepts a small expected cost when it misses in exchange for a chance to win both bets. Arbitrage pays steady and small, middles pay rarely and big.
Most middles miss, and how often they hit depends on how wide the window is and whether it covers key numbers. That is why the price on each side matters so much: good prices keep the cost of a miss small.
