Chestnut barely broke his own world record of 73 1/2 hot dogs which he set in 2016 during a qualifying event.
Chestnut ate 10 more dogs and buns than runner-up, Carmen Cincotti.
Chestnut, who ate a then-record 72 dogs last summer, fended off 20 other eaters at New York's Coney Island boardwalk for the annual Independence Day competition.
That didn't stop the Las Vegas eater from easily beating out second-place finisher Mischelle Lesco of Tuscon, Arizona, who chowed down 28 wieners and buns.
Rich Shea, the president of Major League Eating, which puts on the contest, said the mistake might warrant changes for future counting procedures.
As for the critics and the naysayers, or for those who might get a bit nauseous at the idea of 74 hot dogs within 10 minutes, Shea encourages folks to give the spectacle a shot.
On the women's side, Miki Sudo won the Mustard Belt for the fifth straight year.
Sudo fell short of the 41 hot dogs she consumed previous year, but easily beat out second-place finisher Mischelle Lesco of Tuscon, Arizona, who chowed down 28 wieners and buns. George Shea, MLE chairman, will host the stage show for the historic contest, which has been held in Coney Island, NY, for decades and attracts top eating talent from around the world. Offshore sportsbooks received over $1 million in bets for the contest, Rovell reported.
"I really wasn't looking to beat my personal best or even a record".
While Chestnut earned the $10,000 grand prize for his victory, it did come at a cost in the form of his health. "I'm looking forward to next year".
Washington, D.C.'s, record hot dog eater Juliet Lee shared her secret to competitive eating ahead of the Fourth of July holiday. The prize money, as in years past, is $10,000 for the first place victor. As Chestnut pulled ahead in this year's contest, the crowd took up chanting his name.
