Burger King
#8 of 15 in its sector · -1 vs sector average · best marketing AI 74, lowest training & support AI 58
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.

#7 of 15 in its sector · +4 vs sector average · best data infrastructure 82, lowest training & support AI 56
Chick-fil-A runs one of the deepest in-house data stacks in franchising: a Kubernetes edge-compute cluster in every restaurant, chain-wide since about 2019 and still expanding, with tens of thousands of connected fryers and grills reporting telemetry. Its 2025 forecasting models make about 2.4 billion predictions per pipeline run at over 90% inside-sales accuracy. Customer-facing AI stays limited — orders are still taken by people. The count here is its U.S. restaurants and licensed units, the only figure its franchise disclosure document states.
What actually separates them
The 12-point edge Chick-fil-A holds on operations AI (35% of the score) is worth about 4.2 points, against 3.6 for Chick-fil-A on data infrastructure. The widest raw gap, 14 on marketing AI, counts for less (2.8).
Sector context
In QSR & Fast Food (15 tracked, average 68/100 against 63 for the Index), Burger King ranks #8 and Chick-fil-A #7 on AI, Chick-fil-A above the sector average and Burger King not.
