Aldi (2,669 stores) leads or is tied in an 11-state stretch of the Midwest and Northeast. Its shares run from about 35% to 45%, with Ohio (45.3%) and Michigan (44.3%) the highest. It also maintains a strong presence across Florida and the Southeast.

Target (2,007 stores) leads in Hawaii (52.6%), California (35.4%), and Massachusetts (34.2%). Hawaii is effectively a two-chain market, while Massachusetts and California are more evenly split among the four retailers.
