Why Sportsbooks Love SGPs
Using Correlation to Your Advantage

Os SGPs

Combinam moneyline + total + props do mesmo jogo. A margem efetiva é 15-30% — extremamente rentável para as casas. As seleções correlacionadas são tratadas como independentes, inflando a margem. Para diversão com apostas pequenas: perfeitamente válido. Para rentabilidade: entre os piores tipos de aposta.

No Brasil

SGPs se tornaram extremamente populares nas apostas de futebol brasileiro. Bet365 e Betano promovem SGPs com "boosts" de odds — geralmente ainda têm margem negativa mesmo com o boost.

⚡ CalcWolf Insight

A Harvard study of DraftKings SGP data found the average house edge was 19.7% — nearly 4x the edge on standard spread bets. The most profitable SGPs for the sportsbook were those with 4+ legs, where the compounding margin effect is strongest.
