Arsenal enter the 2026-27 Premier League campaign as defending champions after ending a 22-year title drought in 2025-26, positioning them as the clear market leader at 61.5% implied probability. Their squad continuity under Mikel Arteta and strong early results have reinforced trader confidence despite a recent loss to Brighton. Manchester City sit second at 19.5% amid a perfect start under new manager Enzo Maresca, leveraging attacking efficiency and resources even after Pep Guardiola’s departure. Liverpool, Chelsea, and others trail further back, reflecting slower starts and greater uncertainty in their title paths. Early-season form, defensive metrics, and historical title-retention challenges continue to shape these probabilities as the campaign progresses.
