The house-edge mathematics
Every regulated iGaming product has a published Return-to-Player percentage. A slot at 96% RTP returns 96 cents of every dollar wagered to players on average over the long run; the 4% retained is the operator's gross gaming revenue (GGR) before tax, opex, and content-supplier revenue share. Higher-volatility products have higher per-bet variance but the long-run mathematics are deterministic. Sportsbooks operate on similar mathematics - the bookmaker's margin (the over-round on offered odds) is the equivalent of the slot's house edge.
GGR, NGR, and operator margin
Gross gaming revenue is the headline figure. Net gaming revenue (NGR) subtracts bonus costs, free-bet promotions, and player-loyalty rewards. Operator EBITDA subtracts payment-processing fees (1-3% of stakes), platform-supplier revenue share (often 10-15% of GGR for slot content), marketing and player-acquisition cost (the single largest variable cost for most operators), staff and compliance overhead. The ratio of NGR to GGR - and of EBITDA to NGR - is a key metric for benchmarking operator quality.
Player lifetime value
Operator-economics analysis runs on player-lifetime-value (LTV) cohorts: how much net revenue does a player generate over their relationship with the operator, less the cost of acquiring them. Sports-betting LTV is typically lower per-player than online-casino LTV but acquisition cost is also lower; high-frequency products (slots, sports betting) churn faster but recurring; low-frequency products (poker tournaments, lottery) retain longer but pay-out less per active. CRM teams optimise for the LTV-to-CAC ratio across cohorts.
The supplier revenue-share economy
Most operators do not own their content. Slot content is licensed from studios (Pragmatic Play, Evolution, Light & Wonder, Aristocrat, NetEnt) on revenue-share terms typically 10-15% of GGR. Live-casino content is similar. Sports-data feeds (Genius Sports, Sportradar) carry fixed fees plus revenue-share components. B2B sportsbook platforms (Kambi, others) provide trading and risk-management as a service for operators that do not run their own book - typically 8-12% of sportsbook GGR. This is why operator gross margins are well below the headline house-edge figure.
