# Burger King US market growth and turnaround > Live situation record from CLSTR: https://clstr.news/situations/burger-king-us-market-growth-and-turnaround > Updated: 2026-08-19T04:51:15.000Z. Sources: 12. Developments: 2. Burger King has experienced a significant sales turnaround in the United States, surpassing Wendy’s to become the second-largest burger chain in the country. During the second quarter, the company reported an 8.5% increase in U.S. same-store sales, outperforming growth margins from competitors such as McDonald’s. This growth is largely attributed to the ‘Reclaim the Flame’ initiative, which involves a $700 million investment in technology and restaurant renovations. A central component of this success is the relaunch of the Whopper, which features menu upgrades including a premium bun and updated mayonnaise. Sales of the updated Whopper have reportedly increased by over 20%. While Burger King’s performance has strengthened, its parent company, Restaurant Brands International, has seen mixed results across its other brands. Tim Hortons reported minimal same-store sales growth, and Popeyes Louisiana Kitchen experienced a decline in U.S. same-store sales. ## Timeline ### 2026-08-19: Burger King sees sales surge following Whopper relaunch Burger King's U.S. same-store sales rose 8.5% in the second quarter, outpacing competitors McDonald's and Wendy's following a Whopper relaunch and menu updates led by chef Amy Alarcon. 2 sources. https://clstr.news/cluster/burger-king-sees-sales-surge-following-whopper-relaunch ### 2026-08-10: Burger King becomes second-largest US burger chain Burger King has overtaken Wendy's to become the second-largest US burger chain, driven by a revamped Whopper and a successful multi-year marketing and restaurant renovation campaign. 10 sources. https://clstr.news/cluster/burger-king-overtakes-wendys-as-second-largest-us-burger-chain-2 --- Cite as: Burger King US market growth and turnaround.
