What is the name of Coca-Cola's main cola competitor? Coca-Cola's main cola competitor is Pepsi.
Pepsi is the leading rival in the long-running competition often called the “Cola Wars.” The two brands sell similar carbonated cola drinks and compete for consumers, restaurant agreements, supermarket shelf space, advertising attention, and global distribution. Their rivalry is especially associated with major television campaigns and blind taste tests during the twentieth century.
Pepsi originated as “Brad's Drink,” created by pharmacist Caleb Bradham in New Bern, North Carolina. Bradham renamed it Pepsi-Cola in 1898. That history explains why Caleb Bradham is a plausible historical name but not the answer to this question: he created Pepsi, not Coca-Cola's main competing brand in the marketplace.
Other cola brands, including RC Cola and store-brand colas, also compete with Coca-Cola. Fanta and Dr Pepper are major soft-drink brands, but they are not usually classified as Coca-Cola's primary cola rival. The exact market ranking can vary by country and by measurement, but Pepsi is the standard canonical answer for a general trivia question.
