None of the large retail chains in the Czech market exceeds 10 percent market share, according to a recent study by Incoma GfK. This makes the Czech market unique with its low rate of concentration. “In most countries, the largest retail chain controls 20 to 30 percent of the market, while in the Czech Republic it is less than 10 percent. The situation is similar as regards the three strongest chains. In most countries they control 40 to 60 percent of the market but in the Czech Republic it is only 28 percent,” Incoma GfK executive Tomas Drtina told ČTK. Ahold is number one on the Czech market with 9.7 percent, followed by Kaufland with 9.3 percent and Tesco Stores with 8.1 percent. Most Czechs live in districts where seven retail chains or more are active.
