Chris Kempczinski picked up a Big Arch burger last month, took the smallest possible bite, and called it a "product." By March 9, 2026, KFC, A&W, Jack in the Box, Burger King, and Wendy's had all posted videos mocking him while eating their own food on camera. None of them paid for a single impression of those videos. McDonald's paid for all of them.
This is not a rivalry. It is a free media machine, and every brand running at McDonald's right now knows exactly what they are doing.
One Bad Video, Six Marketing Campaigns
The mechanics are simple. Burger King's Tom Curtis posted a Whopper video hours after the Kempczinski clip went viral, sauce visible, with the line: "There's just one thing missing, napkins." Wendy's dropped a Baconator video on March 4 with the caption: "When you're eating real food, you don't have to act like you enjoy it." Neither video required a media buy. McDonald's mockery did the targeting for them.
The chicken sandwich war of 2019 established the template. Popeyes achieved near triple-digit same-store sales growth during that period, with locations selling out and lines stretching dozens of meters. Popeyes spent almost nothing on that growth. Twitter did the distribution. Chick-fil-A and Wendy's did the amplification by fighting back. The pattern from 2019 is now a playbook, and every social media manager at every major chain has it saved somewhere.
Yes, McDonald's takes the short-term mockery hit. That is a fair point. But "Big Arch" is now burned into consumer memory across six countries, and the chain's social team knows that being the subject of a viral moment beats being ignored by 40 million people who scrolled past a traditional ad. Kempczinski's video was terrible execution. It was not a disaster. The two things are different.
The Math Nobody Is Saying Out Loud
No chain has released March 2026 sales figures yet, but the sector dynamics are not subtle. Consumer price fatigue has hit fast food hard since 2024; McDonald's U.S. traffic declined as customers pushed back against $6 McDoubles. A viral moment that gets people arguing about burgers online is worth more right now than a discount campaign, because it reframes the category as entertainment rather than expense. Every chain benefits from that reframe, not just the one that threw the first punch.
The Popeyes and Church's Chicken biscuit feud that started simultaneously is a smaller version of the same mechanic. Wendy's jumped into that one too, for no strategic reason except that attention was pooling there. When attention pools, you step in. The cost is one social post and thirty seconds of your communications team's time.
I do not think there is anything wrong with this. Brands should compete creatively, and social media is cheap distribution. But the media coverage treating this as a genuine corporate grudge match is doing these companies a favor they did not earn. There is no feud. There is a sector that figured out collective attention generates individual sales, and every participant is smiling while the cameras roll.
The right move for anyone watching is not to cheer for a winner. Pick the chain whose fundamentals you actually trust, because the attention bump is temporary and the balance sheet is permanent. Popeyes got triple-digit sales growth in 2019 and still closed underperforming locations the following year. The meme cycle ends. The rent does not.
Kempczinski took a tiny bite and accidentally wrote everyone else's Q1 marketing plan. That is the most expensive awkward pause in fast food history.
