Burger King has outpaced McDonald's in weekly foot-traffic growth every week since early March, a shift that began just as a pair of viral videos turned the fast-food rivalry into a social-media spectacle, and the numbers suggest the momentum is real.
Placer.ai data shared with The New York Post show that for the week of March 2, Burger King's weekly visits jumped 7.4 percent year over year. McDonald's managed just 2.2 percent growth over the same period. Over the following three weeks the gap widened: Burger King posted gains of 5.4, 2.2, and 3.2 percent while McDonald's slipped into negative territory, declining 0.2, 2.2, and 1.3 percent, respectively.
The divergence lines up neatly with two things: the nearly simultaneous launch of McDonald's Big Arch burger and Burger King's first Whopper overhaul in a decade, and a pair of executive videos that went in very different directions online.
In February, McDonald's CEO Chris Kempczinski appeared in a promotional video for the Big Arch, a 14-ounce burger built on two quarter-pound beef patties and three slices of melted white cheddar. Rather than digging in, Kempczinski appeared reluctant to take a bite, repeatedly calling the burger a "product" and turning it toward the camera to reveal what viewers described as a comically small nibble.
The clip drew immediate mockery. It looked, to millions of viewers, like a CEO who didn't want to eat his own company's flagship launch.
Burger King President Tom Curtis saw an opening. He posted a TikTok video taking a massive bite of the chain's newly upgraded Whopper, captioning it "Thought we'd replay this." The contrast was impossible to miss, one executive treating his burger like a prop, the other treating it like lunch.
As we covered when the Burger King president first responded, the exchange turned the usual fast-food marketing jabs into something with real teeth. What the foot-traffic data now suggest is that the viral moment didn't just generate clicks, it moved customers.
David Palmer, a restaurant analyst at Evercore, tied the foot-traffic divergence directly to the viral videos and the competing burger launches. In a recent note, Palmer wrote:
"It is also true that McDonald's has been underperforming peers such as Burger King in the wake of viral 'CEO burger-bites' videos and the subsequent taste tests of the Whopper vs. the Big Arch burger."
Palmer didn't pin the blame entirely on bad PR. He pointed to broader economic headwinds as well:
"We believe the war and rising gas prices are partly to blame [for slowing McDonald's sales], contributing to overall US same-store sales growth slowing from 3% in early March to flat year over year in the last three weeks."
That distinction matters. Tariffs, the conflict in Iran, and rising gas prices are weighing on consumer confidence across the entire restaurant industry. But McDonald's is underperforming even within that difficult environment. Burger King is not immune to the same macro pressures, yet its traffic kept growing.
The stock market reflects the gap. McDonald's shares have fallen 7.4 percent over the past month. Restaurant Brands, the parent company of Burger King, Tim Hortons, and Popeyes, is up 4.9 percent over the same stretch.
McDonald's has not stood still. The chain has leaned into value offerings and specialty drinks, and plans to roll out a new line of beverages, including a creamy vanilla cold brew coffee, along with an under-$3 menu aimed squarely at budget-conscious customers. The Big Arch itself launched on menus March 1 as a limited-time offering.
Palmer compared the coming value menu to Taco Bell's successful Luxe Menu, noting it is "designed to provide low entry price items on an a la carte basis (unbundled)." He said it "may help address McDonald's traffic issues with low income consumers."
But the Evercore analyst stopped short of calling it a fix. Palmer was blunt about the competitive picture:
"In our view, McDonald's new value strategy is not a 'game changer' for competitors with momentum like Restaurant Brands's Burger King or Yum! Brands' Taco Bell."
He added that the value push "will help McDonald's traffic over time, especially when combined with other initiatives." That's a polite way of saying the current trajectory isn't good enough on its own.
McDonald's did not immediately respond to The Post's request for comment.
The foot-traffic win doesn't exist in a vacuum. Burger King has been on an aggressive expansion footing in recent months. The chain launched a 60,000-worker hiring push even as some competitors shuttered locations, a signal that its parent company sees sustained demand worth investing in.
Placer.ai, which provided the data, cautioned that shifts in foot traffic "can be tied to many different factors, including heightened economic uncertainty, lower consumer confidence, holiday store closures, and weather conditions." Fair enough. No single data set tells the whole story.
But the timing is hard to dismiss. The updated Whopper hit menus just days before the Big Arch. Both chains launched major new products into the same market window. One chain's traffic climbed. The other's fell. And the most visible difference between the two campaigns was a CEO who wouldn't eat his own burger and a president who couldn't wait to eat his.
In the broader competitive landscape of American burger chains, perception and product quality are inseparable. Consumers notice when leadership looks disconnected from what it's selling. They notice even faster when a rival calls the bluff on camera.
There is a straightforward takeaway here, and it has nothing to do with tariffs or gas prices. Consumers reward authenticity and punish phoniness, especially when the phoniness is served up on a sesame-seed bun in a promotional video.
McDonald's still has enormous scale, deep pockets, and a global brand that dwarfs Burger King. Nobody is writing its obituary. But the company's leadership handed its chief rival a gift, and Burger King cashed it in with a Whopper upgrade, a well-timed TikTok, and a president willing to take a real bite.
In a free market, customers don't owe you loyalty. You earn it every day, one honest bite at a time.
