Overview

• CosMc’s launched in December 2023 as a drive-thru, beverage-focused prototype designed to test bold, customizable offerings against Starbucks and Dunkin’.
• After an initial surge in Bolingbrook, Illinois, McDonald’s closed three of seven CosMc’s outlets in January 2025 and shelved further Texas expansion plans.
• The CosMc’s app and online ordering will be discontinued on June 23 ahead of the staggered late-June shutdown of its five remaining sites.
• Select CosMc’s flavors will be rolled into a U.S. beverage trial across more than 13,000 McDonald’s restaurants later this year.
• McDonald’s says insights from the CosMc’s experiment will inform future drink innovation in an increasingly crowded market.
