Definition
No-vig odds are betting lines with the sportsbook's margin removed, showing the true probability-based price. Also called 'fair odds' or 'true odds.' When a sportsbook offers better odds than the no-vig line, you have a +EV opportunity.
Example
Market shows -115/+100. No-vig calculation: -115 implies 53.5%, +100 implies 50%. Total = 103.5%. Removing vig: 53.5/103.5 = 51.7%, 50/103.5 = 48.3%. No-vig odds: -107/+107.
