Market Margins and TRJ Overview. Most bookmakers display TRJ between 92% and 97%, reflecting active competition on this Serie A fixture. Three books stand out with more aggressive margins: 888sport (91.7%), LeoVegas (91.6%), and Winamax FR (92.1%), while Betfair (99.2%), Matchbook (98.9%), and 1xBet (98.4%) accept larger volumes. Pinnacle, the market reference, posts 97.1% TRJ, confirming overall pricing efficiency.
Potential Value on Bologna. Pinnacle's fair odd on the away win stands at 4.22. Three bookmakers offer 4.30 (Betfair, Unibet SE, Unibet NL)—a +1.8% edge over the reference. This value is marginal yet observable, reflecting slight overvaluation by these three operators. Conversely, low Bologna odds (3.75 at Winamax FR, 3.85 at Winamax DE, 3.90 at 888sport) offer weak relative payouts.
Opportunities on Draw and Home Win. On the draw, the best odd is 3.73 (1xBet) versus a fair odd of 3.77: no value signal detected. On Atalanta's win, the maximum reaches 1.99 (Matchbook) against a fair odd of 2.01: again, no statistically significant positive signal. The asymmetry confirms value concentrates exclusively on the away outcome.
Optimal TRJ and Arbitrage Perspective. Combining Matchbook (1.99), 1xBet (3.73), and Betfair (4.30) yields an optimal TRJ of 99.7%. This minimal 0.3% gap versus 100% signals a highly liquid and efficient market, where classical arbitrage spreads are scarce. Observed value signals remain marginal and subject to quote volatility; direct verification via CalculaBet's Value Bet, TRJ, and Surebet calculators is advised before committing capital.
