No — while the two are both owned by Belgian beverage giant, AB InBev, Budweiser and Bud Light have some key differences. For one, Bud Light is vastly more popular than traditional Budweiser (Bud Light rakes in nearly three times as much annual profit as Budweiser), and it’s the best-selling beer in the United States. Budweiser, at 5% ABV, is a standard American lager with 145 calories per can. Bud Light, on the other hand, is (as the name suggests) a lighter version of the OG beer, with just 4.2% ABV and 110 calories.
