The strongest evidence is the sportsbook consensus, which implies about a 59.4% Arsenal home win chance. With no reliable additional information on injuries, rotations, or tactical context, I anchor near that market estimate. Arsenal’s home advantage and the fact both teams are 2-0-0 suggest a strong opponent but do not clearly outweigh the market prior. I trim slightly below the consensus to reflect uncertainty and the possibility Chelsea are stronger than generic pricing assumes, but Arsenal remain more likely than not to win.

Both teams are 2-0-0 early in the season, suggesting similar form. The sportsbook consensus gives Arsenal (home team) a 59.4% win probability. Arsenal historically performs well at home against Chelsea. Given the equal early-season records and the sportsbook consensus, I'll slightly adjust toward the sportsbook figure. The base rate for home wins in Premier League is roughly 45-50%, but Arsenal vs Chelsea at Arsenal tends to favor Arsenal. I'll set my estimate close to the sportsbook consensus at 0.57.
