Restaurant Brands International calls Burger King the world's second largest quick-service hamburger chain; it had 19,900 restaurants at the end of 2025, up 0.9% in a year. Its AI is one early programme: BK Assistant, introduced in February 2026, and «Patty», a voice-AI headset assistant piloted in about 500 U.S. restaurants — under 3% of the system — with a U.S.-wide rollout planned by the end of 2026.

The company itself, which is private, publishes nothing about AI in demand planning or site selection.
