Vig (Vigorish/Juice)
The commission sportsbooks charge on every bet, built into the odds.
Like the convenience store markup - paying $5 for a $4 item.
Why it matters
The vig is why sportsbooks always profit. You need to beat the vig to make money.
How DMP uses this
We remove the vig when calculating true odds and fair value.
Common mistake
Ignoring vig when comparing lines across books.
