Break-even and long-run results

The implied probability of -1550 is 93.94%, and that number is also the break-even win rate: win more often than 93.94% of the time at this price and you profit in the long run, win less often and you lose. The table shows the return on stake at a few win rates, including the break-even rate itself.

At 93.94% this is a heavy favourite. Prices this short appear when one side is expected to win comfortably: a top seed against a qualifier, a strong home team against a relegation candidate, or a moneyline in a game with a double-digit spread. The catch is the payout. You need to win more than 93.94% of these bets just to stand still, and one loss wipes out several wins.
