Miki Sudo defended her title as well in the women's division.
Saturday marked the 18th time Chestnut, 42, won the so-called Mustard Belt in just 21 appearances at the internationally televised Nathan's Famous Fourth of July hot dog eating contest. He beat out 13 competitors who came from around the country and world, trekking from the Czech Republic, Australia and South Korea.
"It's a dream, it's electric, there's no place better on Earth," Chestnut said breathlessly in an interview immediately after the showdown, donning a bulky, bejewelled necklace bearing the name of the sports betting company "Polymarket" around his neck.
In a video posted on Instagram before the competition, Chestnut called competitive hot dog eating "the most patriotic sport we've got".
Chestnut handily defeated the second-place winner, Patrick Bertoletti, 41, who ate 50 hot dogs, but fell short of his own 2021 record of 76 wieners and buns - or approximately 7.6 hot dogs per minute.
Defending champion in the women's division, the 40-year-old Sudo of Tampa, Florida, won the bright pink Mustard Belt for the 12th time, downing 38.75 dogs. In 2024, she ate a record 51 links.
After competing, Sudo joined the crowd to watch her husband - who proposed to her in 2021 immediately after downing 50 boiled eggs in just over 3 minutes to set a world record - compete in the men's event.
Both champions said that the heatwave that scorched New York on Saturday - bringing temperatures in Brooklyn to roughly 32C during the competition - made that much more difficult. ESPN announcers said the humidity changed the consistency of the buns.
A large crowd braved the heat to watch the event, wearing foam hot dogs on their heads and standing outside the original Nathan's Famous restaurant that has been in Coney Island, Brooklyn, since 1972. The superfans who stood closest to the stage wore ponchos as protection in case a competitor threw up.
There was briefly some concern earlier this year that Chestnut wouldn't be able to participate in the 2026 competition after he was arrested for allegedly slapping a man in an Indiana bar.
He was put on probation after pleading guilty to misdemeanour battery, but is allowed to travel outside Indiana. Hot dog contest organiser Major League Eating said the criminal case didn't affect Chestnut's eligibility for the competition.
Despite his continued reign, Chestnut told an ESPN interviewer after the game that he was disappointed that he wasn't able to top his previous record.
"Dang, I got so much room left," said Chestnut, who announcers referred to as the "Michelangelo of Mastication".
