Bet25.com has launched its Zero Margin Sportsbook, a product it says removes the hidden house edge built into traditional sportsbook odds.
According to the Berlin-based team, standard bookmakers reduce odds by 5% to 10% per selection before a bet is placed. On single bets this can appear minor, but on multi-leg parlays the hidden cuts compound. Bet25 says its model calculates odds using “pure math” with no built-in margin, and instead applies one flat 5% service fee per bet slip, regardless of how many picks are included.
In its example, a five-leg parlay with true 50/50 probability is priced at 2.0 per outcome rather than a regular bookmaker’s typical 1.87. With the same five picks and a $100 stake, Bet25 claims the payout would be $755 higher because no hidden cuts are multiplied along the way.
Bet25 partnered with Vegangster as its primary platform provider, working from initial ideation through deployment. The company is owned by Horns and Hooves Company S.A, registered in Costa Rica, and operates under a gaming licence issued by the Government of the Autonomous Island of Anjouan, Union of the Comoros, under Licence No. ALSI-202505001-FI1.
