Burger King has overtaken Wendy's as the second-largest burger chain in the U.S. by systemwide sales, retaking its crown six years after losing it to the rival chain. McDonald's holds onto its spot as the number one burger chain, with a significant lead. For comparison, at that time, Wendy's had an 11.4% share of the market, while Burger King had a 10% hold. Both Wendy's and Burger King had to navigate the Covid-19 pandemic and the subsequent supply chain issues that led to soaring food costs. Now Wendy's is planning to embark on its own turnaround to revive sales, meaning that Burger King can't rest on its laurels.
