Two companies dominate the global rankings, but the stories behind individual brands are far stranger than the sales charts suggest — a whiskey mixer, a wartime workaround, and a drink older than both Coca-Cola and Pepsi all make the list.
Rankings like this vary depending on whether you measure by revenue, sales volume, or brand awareness, and results can shift meaningfully between countries. The list below reflects a blend of global market share and worldwide sales figures, giving the clearest overall picture of genuine international reach — though as you'll see toward the end, "most popular globally" and "most popular where you actually live" aren't always the same thing.
The Global Top 10
Ranked by worldwide market share and sales, based on recent industry data.
Coca-Cola
The undisputed global leader, sold in over 150 countries and holding roughly 22% of the worldwide soft drinks market. Invented in Atlanta in 1886 by pharmacist John Pemberton, it was originally sold by the glass at a soda fountain as a patent medicine before becoming the best-selling carbonated soft drink in history. The recipe's exact flavouring formula remains one of the most famously guarded trade secrets in the world.
Pepsi
Coca-Cola's long-standing rival, sold in more than 200 countries and territories. Owned by PepsiCo, it holds around 15% global market share and remains the world's second-largest soft drink brand by a clear margin. The decades-long "Cola Wars" marketing rivalry between the two brands became one of the most studied advertising battles in consumer history.
Fanta
Created in Germany during the Second World War, when a trade embargo cut off Coca-Cola's usual syrup supply to its German operations. Forced to improvise with whatever ingredients were available at the time, including fruit pulp and whey byproducts, the result became Fanta — now sold in more than 190 countries in dozens of fruit flavour variations.
Sprite
Coca-Cola's answer to 7UP, launched in 1961. Its clean lemon-lime flavour and simple, minimal branding helped it become one of the most recognised non-cola soft drinks globally, now sold in around 190 countries and generating roughly $6 billion in annual sales, with India alone accounting for a significant share of that figure.
Dr Pepper
First sold in Texas in 1885 — genuinely older than both Coca-Cola and Pepsi. Famous for its unusual flavour, often described as a blend of 23 different ingredients, Dr Pepper has built a loyal following through its sheer distinctiveness from every other cola-style drink, refusing to be easily categorised as a cola, root beer, or fruit soda.
Mountain Dew
Created in the 1940s not as a soft drink at all, but as a mixer for whiskey — its citrus punch was designed to complement spirits, not stand alone. PepsiCo acquired the brand in 1964 and repositioned it around bold, extreme-sports marketing, a strategy that's remained largely unchanged and has made it a particular favourite among gamers.
Red Bull
Originally launched as "Krating Daeng" in Thailand, later reformulated and rebranded for Western markets by Austrian entrepreneur Dietrich Mateschitz. Now sold in 177 countries, Red Bull effectively created the modern energy drink category rather than competing within an existing one, and remains the category leader by a wide margin decades later.
Schweppes
The brand that arguably started the entire industry — founded in 1783 on Johann Jacob Schweppe's process for bottling carbonated water. Today it's best known for tonic water and ginger ale, remaining a household name for mixers across the UK and beyond, and still trading on a heritage that predates every other brand on this list by over a century.
7UP
One of the original lemon-lime sodas, launched in 1929 — and the drink Sprite was specifically created to compete against three decades later. Despite Sprite's global dominance today, 7UP retains a strong following in markets where it was established long before its Coca-Cola-owned rival ever launched.
Guaraná Antarctica
A reminder that global rankings don't tell the whole story — this Brazilian soft drink, made using extract from the caffeine-rich guaraná berry native to the Amazon, remains a genuine national staple, consistently outselling Coca-Cola and Pepsi within Brazil itself despite barely registering on worldwide sales charts.
The Zero-Sugar Versions Are Now a Category of Their Own
It's worth noting that several diet and zero-sugar variants have grown large enough to be considered major brands in their own right, rather than simple spin-offs. Diet Coke and Coke Zero together represent a substantial share of Coca-Cola's total sales, while Pepsi Max has become one of the UK's genuinely best-selling soft drinks in its own category, independent of full-sugar Pepsi. This shift has accelerated significantly since sugar taxes like the UK's Soft Drinks Industry Levy pushed manufacturers to reformulate or risk higher pricing — a trend we cover in more depth in our guide on what actually separates juice from soft drinks under UK law.
The One Place Coca-Cola Doesn't Win
Guaraná Antarctica isn't the only local hero bucking the global trend. In Scotland, the bright orange, famously indescribable Irn-Bru — made by Scottish company A.G. Barr and often nicknamed "Scotland's other national drink" — has held its own against Coca-Cola for decades, remaining one of the very few markets in the world where a homegrown soft drink genuinely competes with, and has at times outsold, the world's biggest brand on its own home turf. Its exact flavouring, much like Coca-Cola's, is a closely guarded secret known to only a handful of people at any given time. It's proof that global market share doesn't always predict what people actually reach for on their local shelf.
