Trader Joe's is owned by a family trust associated with the founders of Aldi Nord, operating as a distinct American subsidiary within their broader corporate umbrella. It is important to note that the global Aldi enterprise split decades ago into two separate companies—Aldi Nord and Aldi Süd. In the United States, Trader Joe's is owned by Aldi Nord, whereas the traditional "Aldi" grocery stores operating across the US are managed separately by Aldi Süd.
