Arsenal enter the 2026/27 Premier League campaign as defending champions under Mikel Arteta, with a settled squad and strong set-piece record that underpins their 61.5% implied probability as title favorites. Despite a 3-0 defeat at Brighton that ended their perfect start, the Gunners sit second after five matches and retain the wisdom-of-crowds edge in futures markets. Manchester City’s flawless 5-0 record and top position have not closed the gap to similar levels, leaving them at 17.5%. Liverpool, Chelsea, and the rest trail further behind amid inconsistent early results and squad transitions. Injury updates, including concerns around key attackers, add uncertainty but have not shifted the market hierarchy substantially in the opening weeks.
