PepsiCo: The Rival That Stopped Fighting on ColaWide moat

The most famous rivalry in consumer goods has been decided for a long time. Coca-Cola holds about 48% of the US carbonated soft drink market against PepsiCo's 26%, and globally roughly 44% to 21%¹. Those gaps have been durable across generations of marketing spending.

What PepsiCo did in response is the interesting part: it stopped competing primarily on cola. Through Frito-Lay and Quaker it became a company where snacks generate a large share of profit, and where beverages are one business among several. That produces a competitor with a different objective function — one that will not fight a price war over cola share because cola share is not what its earnings depend on.

For Coca-Cola this is mostly good news and slightly bad. Good, because a rival focused elsewhere is not attacking the core; the concentrate economics the moat pages describe survive precisely because neither party wants a price war. Slightly bad, because PepsiCo's diversification gave it a growth engine Coca-Cola deliberately does not have, having chosen to remain a beverage company.

Watch relative price realisation rather than share. Two rational duopolists raising prices in parallel is the equilibrium that makes both profitable; the signal that something has changed would be either one discounting to move volume.
