Section I — The Intake Event
On February 3, 2026, Christopher Kempczinski, Chief Executive Officer of McDonald's Corporation, posted a video to his Instagram account. The purpose of the video was to promote a new menu item called the Big Arch. Mr. Kempczinski held the burger, described its attributes, and took a bite.
The bite was small.
"That is so good," he said. "That's a big bite for a Big Arch."
The Bureau wishes to note, for the record, that the bite was not a big bite. The subject appears to have known this at the time of speaking.
Section II — The Product
The Big Arch is not a new concept. It launched in Canada in June 2024, arrived in Portugal, the United Kingdom, and Australia before 2025 was out, and formally entered the United States on March 3, 2026 — twenty-eight days after the video that would define its American debut.
The burger weighs 395 grams. It contains two beef patties equivalent in weight to Quarter Pounder patties, three slices of white cheddar, a proprietary sauce, raw and grilled onions, lettuce, pickles, and a bun topped with sesame and poppy seeds. It contains 1,020 calories — approximately 440 more than a Big Mac. It costs between $6.89 and $12.99 depending on location, a pricing variance of 88% across outlets operated under the same brand.
It was designed, Mr. Kempczinski explained in the video, to address "unmet customer needs with a more satiating burger."
He used the word "product" six times in the video. He used the word "burger" once.
Section III — The Bureau Opens a Case
For twenty-two days, the video circulated without incident. Then, on February 25, Irish musician Garron Noone posted a response to TikTok. It received millions of views within hours. The Bureau has noted Noone's central finding, submitted without supporting argument: "This man does not eat McDonald's."
The finding was not contested.
A second creator parody by Cat Sullivan reached 17 million views. Documented viewership across reposts, memes, and derivative content reached 70 million. The marketing consultancy Apex Marketing valued the aggregate attention at $18.4 million in earned media.
Foot traffic at McDonald's locations in the week of the Big Arch's official U.S. launch increased by 2.2%.
The Bureau notes the gap between attention generated and people who subsequently walked through a door.
Section IV — The Competitive Response Chain
The fast-food executive class mobilized within 72 hours. The Bureau documents the responses in order of receipt:
Burger King — President Tom Curtis appeared in a branded apron eating a Whopper. "Only one thing missing: a napkin." The video received 956,000 likes on TikTok. Burger King's Instagram comment on the original McDonald's post — "we couldn't finish it either" — received 71,000 likes. Burger King subsequently clarified that the response video was not made in reaction to anything.
Wendy's — U.S. President Pete Suerken ate a Baconator with fries dipped in a Frosty. LinkedIn caption: "Lots of chatter this week about burgers." Wendy's also commented directly on the McDonald's post: "your CEO reads this as a threat." Wendy's subsequently launched a Chief Tasting Officer competition with a $100,000 prize.
KFC — U.S. President Catherine Tan-Gillespie ate a chicken sandwich in a red KFC bomber jacket. "We'll leave that beef to the boys. No 'products,' just finger lickin' good chicken."
Jack in the Box — The brand mascot held up a burger with a demonstrably large bite removed and commented on the McDonald's post: "from one CEO to another: eat your product."
A&W Canada — Brand actor Allen Lulu appeared wearing a blue shirt and sweater combination visually identical to Kempczinski's, then took a large bite of a Teen Burger. "We love this burger product … which most people call a burger."
Carl's Jr. — Declined to participate, stating they would not post "a staged video of our CEO eating a burger."
The Bureau notes Carl's Jr.'s position without further comment.
Section V — The Defense
On April 6, 2026, Mr. Kempczinski gave a sit-down video interview to the Wall Street Journal, conducted by business columnist Tim Higgins. The interview ran approximately eleven minutes.
During it, Mr. Kempczinski offered the following explanation for the February 3 intake event:
"I'm definitely not a vegetarian. I blame it all on my mom, 'cause she told me, 'Don't talk with your mouth full.' I think probably in that case, I should have just said, 'You know what, to hell with it, I'm gonna talk with my mouth full.'"
The Bureau acknowledges the defense.
The Bureau also notes that the etiquette lesson cited — do not speak while chewing — is resolved by chewing more, not by chewing less. A smaller bite does not prevent speech. It accelerates the moment at which speech is again permissible. The defense does not explain the bite. It explains the silence that followed the bite.
Mr. Kempczinski also confirmed, during the same interview, that he eats McDonald's three or four times per week.
Section VI — The Remediation Attempt
During the WSJ interview, Mr. Kempczinski ate a McNugget on camera.
Interviewer Tim Higgins observed: "It's a little weird to watch each other eat."
Mr. Kempczinski replied: "Imagine how I felt."
The McNugget bite generated its own cycle of public commentary. Selected findings, submitted without editorial intervention: "The nugget bite was worse than the burger one." "Even the nugget bite was ragebait."
The Bureau closes this section without further findings.
Section VII — Filed
Marketing professor Mark Ritson, writing in Adweek, observed: "The higher you rise, the further you get from the product you sell."
The Bureau notes that the subject used the word "product" six times in a sixty-second promotional video and that this may be the most precise thing he said.
McDonald's Corporation is the largest fast food chain in the world by number of locations. It operates in 119 countries. It serves approximately 69 million customers per day. Its institutional identity is built on accessibility — on the proposition that the same burger is available to anyone, at a price point that does not require deliberation, in a room that does not require a reservation.
Its Chief Executive Officer was raised not to eat like that.
The Big Arch remains available at participating locations. Pricing varies by market. The Bureau does not endorse any particular bite size. The case is filed.
