Kroger made final arguments for merger with Albertsons. Albertsons owns Safeway so now Kroger meglo corp international gmblz will be the largest grocery business in the usa. Kroger will own Alberstsons, Jewel-Osco, Safeway, Dillons, Food-4-Less, Fred Myers, Frys, Harris Teeter, Home Chef, King Soopers, Mariano's, QFC, Ralphs, Roundy's, JayC, Smiths and Vitacost.
Aldi is German owned. They own trader joes and recently bought Winn-Dixie & Harveys making them second largest food meglo corp
In 2024, Trader Joe's joined SpaceX in a lawsuit to have the National Labor Relations Board, which enforces U.S. labor law in relation to collective bargaining and unfair labor practices, deemed unconstitutional.
Where I live they'd own Albertsons, Food 4 Less, Ralphs, Vons, pretty much everything except Target, Walmart, Whole Foods/Amazon Fresh, and some smaller and specialty grocers like Aldi/Trader Joes.
Also, last I checked, there are two Aldi corporations (Aldi sud/Aldi nord), one of them owns Trader Joes, the other one runs US Aldi stores, they're not the same entity (though there is a history there) and though they often seen to share a fraction of product ideas I can say the same product at the two stores are often noticeably different and almost certainly made by different suppliers.
According to wikipedia Aldi Nord owns USA Aldi's and Trader Joes but says they operate them separately and Aldi Sud owns Winn-dixie and Harveys. They both own Aldi's in Germany which must be confusing because even their logos look similar. I've heard one of the Aldi's in Germany is considered upscale so maybe the good German Aldi's is owned by Aldi Sud.
US Aldi is owned by Aldi Süd. Trader Joe’s is not technically owned by Aldi Nord, but rather by the family who own Aldi Nord.
