Burger King's president just bit back — literally — at McDonald's in a fast-food rivalry that has consumers and social media paying close attention.
Days after a clip of McDonald's CEO Chris Kempczinski eating the chain's new Big Arch burger went viral, Burger King president Tom Curtis posted a video of himself taking a large bite of the Whopper, delivering what many interpreted as a pointed response to his competitor.
According to the Daily Mail, in the original clip, Kempczinski appeared to nibble carefully on the Big Arch before remarking, "That's a big bite for a Big Arch." The video quickly circulated online, with fast-food fans poking fun at what they saw as an underwhelming display. The contrast with Curtis's video could not have been more stark.
Wearing an apron and standing behind the counter, Curtis leaned into the theatrics. He chomped down on the Whopper before nodding approvingly at the camera. His commentary was minimal but effective: "Only one thing missing. A napkin."
The video landed with fast-food audiences. One social media user responded, "Now that's a real bite." Another commenter on Instagram wrote, "That burger is four times the size of a McDonald's burger and tastier too."
At least one customer used the moment to ask about recent changes: "Did you change the buns? The Whopper I had last time was great and fresh." Whether or not the stunt moves market share, it's clear Burger King got the attention it was after.
The Big Arch is McDonald's latest menu addition, featuring two beef patties and three slices of white processed cheese. It was officially due to launch on McDonald's menus the same day the article was published, though some customers reportedly got their hands on it early, sharing mixed reviews on social media.
Here's what the Big Arch brings to the table nutritionally:
That's a hefty price and calorie count for a single fast-food item. For context, when the Double Big Mac — with four patties instead of two — returned in January 2023 for a limited run, it was priced at just $7 and proved to be a hit during its month-long availability.
The plan for the Big Arch didn't emerge in a vacuum. In 2024, McDonald's reported its first sales decline since COVID lockdowns shuttered restaurants. The company has been working to win customers back with new products and competitive pricing.
The fast-food market is ruthlessly competitive, and consumers are increasingly price-sensitive. A burger north of $9 before tax in New York is a tough sell when inflation-weary diners are already rethinking their spending habits. Whether the Big Arch can reverse McDonald's sales trend remains to be seen.
Meanwhile, Burger King has been making moves of its own. The chain recently unveiled a revamped version of the Whopper for the first time in a decade, describing it as an "elevated" offering with "better tasting" mayonnaise. That's a clear signal that Burger King sees an opening while its rival recalibrates.
For those watching the fast-food sector from an investing perspective, this episode is more than a viral marketing moment. It reflects real competitive dynamics in an industry where brand perception and pricing power are everything. A CEO who can't convincingly eat his own product on camera isn't just a meme — it's a branding risk.
Free markets reward companies that deliver value, and punish those that don't. McDonald's is betting that a bigger, more expensive burger will excite consumers enough to reverse declining sales. Burger King is betting that a well-timed counterpunch and a refreshed core product can steal share. The consumer will decide who wins. What's clear is that both chains understand the stakes. In a saturated market with rising input costs and tighter consumer budgets, every product launch and every viral clip matters. The fast-food wars aren't fought with advertising budgets alone — they're fought one bite at a time.
