ROI distribution and book generosity: ROI varies from 93.0% (888sport, PMU) to 99.4% (Betfair, Matchbook), revealing significant market fragmentation. Betfair and Matchbook dominate with best overall conditions (99.4% ROI), while French books (PMU 93.3%, 888sport 93.0%) and some US operators display lowest ROI. Coolbet and GTbets also position at 97.8%, just above Pinnacle (97.5%).
Value on Haiti (odds 2): Pinnacle benchmark sets fair odd at 17.43 for Haiti victory. Betfair and Matchbook exceed this implicit probability by offering 21.00 (+20.5% value), creating notable potential opportunity for bettors seeking overvaluation. Marathon Bet (18.75, +7.6%), 1xBet (18.50, +6.1%), Betsson and Nordic Bet (all at 18.50, +6.1%) complete the offering with moderate value. Other books (13.00 to 17.25) remain under or aligned with fair odd.
Optimal ROI analysis and surebet signal: Combining best odds (1.23 on Morocco at GTbets, 8.00 on draw at Betfair, 21.00 on Haiti at Betfair), optimal ROI reaches 101.5%, exceeding the 100% threshold. This signal indicates sufficient odds dispersion across books to potentially constitute cross-book arbitrage. Important: this opportunity must be verified live with books, as odds move quickly and gaps may close before placement.
Usage recommendations: For single Haiti value bet, Betfair/Matchbook (21.00) offer strongest edge vs Pinnacle. For multi-book optimization via ROI calculator, GTbets/Betfair composition warrants verification.
