How Online Sports Gambling Sites Make Money Explained

Online sports gambling sites thrive on smart revenue models beyond the thrill of betting. Understanding their income streams reveals why bonuses are key hooks for players.

The Vig: Core Profit Engine

Vigorish (vig or juice) is the site's cut, typically 10% on -110 odds. For every $110 bet to win $100, the house pockets $10 per balanced action.

  • Standard NFL/MLB lines
  • Reduced juice promos
  • Scales with volume

Bonus Wagering Requirements

Bonuses lure deposits but require 5-15x playthrough. Most bets lose, keeping funds house-bound. Sign-up offers generate long-term profit.

  • Risk-free bets recouped via vig
  • Loyalty bonuses encourage volume
  • Abuse detection saves millions

Other Revenue Streams

Affiliates earn 30-50% rev-share, boosting acquisition cheaply. Premium tools and data sales add layers.

  • Prop bets with higher vig
  • Casino crossovers
  • Esports emerging margins

Player Retention Tactics

Odds boosts and parlays inflate perceived value, masking true edges. High-volume sharps are limited, protecting profits.

  • Cash-out fees
  • Max bet caps
  • Dynamic line shopping blocks
