Buster Douglas is remembered as a 42-to-1 underdog. Nobody was ever paid at 42-to-1.
The Mirage posted that number and it sat there untouched while money kept arriving on Mike Tyson. The longest price anyone actually collected on Douglas was 38-to-1, on a stake of $1,500. That gap, between the figure people repeat and the figure somebody could’ve actually been paid, runs through most of the biggest boxing upsets, and it’s the part worth looking at.
The Price Nobody Was Ever Paid
Tyson went to the Tokyo Dome on 11 February 1990 at 37-0 with 33 knockouts, aged 23, carrying a $6 million purse and a Holyfield fight already signed for that summer. Douglas was 29-4-1. He stood 6 feet 4, six inches taller than the champion, and he’d never won a world title.
Jimmy Vaccaro ran the Mirage sportsbook at the time, and he’s the one who walked Action Network through how the number moved. Douglas opened around 27-1. At that price Vaccaro booked $54,000 on Tyson to win $2,000. He pushed the underdog to 31-1 and got roughly $93,000 on Tyson to win $3,000. He eventually laid 38-1 on Douglas to an old hand who told him, “No fighter deserves that much respect.” Then 42-1 went up, and nothing came back on it.
| Douglas price | Implied | What happened |
|---|---|---|
| 27-1 | 3.57% | Tyson money kept coming |
| 31-1 | 3.12% | Tyson money kept coming |
| 38-1 | 2.56% | longest price actually struck |
| 42-1 | 2.33% | posted, never taken |
Four numbers, then. Not one. The famous one is the only one that never traded, which is worth remembering the next time a list of upsets hands you a single figure and moves on.
The largest single wager Vaccaro booked was $168,000 on Tyson to win $4,000. Meanwhile the warning signs were sitting in plain view. Tyson had arrived in Japan a month early and barely trained, and his sparring partner Greg Page had put him down in the gym. Douglas had buried his mother, Lula Pearl, 23 days before the fight. He got off the floor after a Tyson uppercut dropped him late in the eighth and stopped the champion 1:23 into the tenth.
One wrinkle on sourcing. The World Boxing Council’s own retrospective describes Las Vegas sportsbooks, plural, making Tyson a 42-to-1 favourite. ESPN and the bookmaker who actually set the line both say one book. Take the bookmaker.
Why Only One Book Priced Tyson at All
Every sportsbook in Nevada took action on that fight. Almost none of it was on who’d win.
Vaccaro’s account is that the rest of the market offered only round and method props, and the most popular bet in town had Tyson ending it in the second or the third. His reasoning for eventually giving up on a straight price was simple enough: as Tyson kept flattening people, the underdog drifted from 6-1 to 8-1 and onward, until the exercise stopped meaning much.
So the odds everyone quotes were one trader’s opinion, posted at one counter, with nothing competing against them. Vaccaro also happened to have authority most of his peers lacked, since he could move a number without clearing it upstairs. A price set that way tells you what one man thought. It doesn’t tell you what a market concluded, and the difference matters when someone builds an argument on the figure. Our page on underdog betting philosophy goes further into what a price does and doesn’t represent.
What Ruiz Cost, Depending on Where You Looked
Andy Ruiz Jr. fought Anthony Joshua at Madison Square Garden on 1 June 2019 because Jarrell Miller had failed multiple drug tests and lost his licence. Ruiz took the fight on relatively short notice.
Three books, one night, three different opinions. The Westgate SuperBook closed Ruiz at 10-1, William Hill at 12-1, FanDuel at 14-1. That runs from 9.09% implied down to 6.67%, and it’s $400 per $100 staked between the best number and the worst.
Joshua scored the first knockdown, in the third round, and looked close to ending it. Ruiz put him down twice in that same round, twice more later, and the referee waved it off in the seventh.
Now the figure that should be on every page about this fight. Action Network reported that 96% of the bets William Hill wrote in Nevada were on Ruiz, while 90% of the total money was on Joshua. Nick Bogdanovich, who ran trading for the book, said the 12-1 price meant William Hill finished a small loser on the night.
Read those two percentages again, because they describe the same fight. Count tickets and the public was overwhelmingly on the underdog. Count dollars and the public was overwhelmingly on the favourite. Most published betting splits report one of those without saying which, and the two can point in opposite directions on the same event. We cover that in more detail on public betting trends and in the piece on fading the public.
The worst individual result of the evening was a $100,000 bet on Joshua at a Nevada William Hill, laid to win $5,000. Joshua took the rematch six months later in Diriyah, down from the 248 pounds he weighed in New York, boxing at range for a decision. No stoppage, and no repeat.
Clay Got Longer as the Fight Got Closer
Cassius Clay met Sonny Liston at the Miami Beach Convention Hall on 25 February 1964, in front of 8,300 people. Liston came in 35-1 with 24 knockouts. Clay was 19-0 and 22 years old.
The line went the wrong way for anyone hoping to catch the underdog cheap. Contemporary accounts put Clay around 7-1 when the price appeared, and Wikipedia’s account of the fight has him at 8-to-1 by the opening bell. That’s 12.5% drifting out to 11.1%. Of the 46 sportswriters at ringside, 43 picked Liston to win inside the distance.
What almost nobody priced was Liston’s condition. He’d been carrying bursitis in both shoulders for close to a year and taking cortisone for it, and he re-injured the left one in training. He retired on his stool after six rounds. Joe Louis called it “the biggest upset in the history of boxing,” a claim Douglas would take off him 26 years later.
A price that lengthens into a fight is doing something, and it usually isn’t what a contrarian wants. See line movement value for what a move like that tends to mean.
Braddock and the Graveyard of Champions
James J. Braddock beat Max Baer over fifteen rounds at the Madison Square Garden Bowl in Long Island City on 13 June 1935, in front of 29,366 paying customers. He was a 10-1 underdog, and by Action Network’s reckoning that stood as the benchmark for a heavyweight title underdog right up until Tokyo.
He’d been working the docks and drawing public relief. Damon Runyon called him the Cinderella Man, and Russell Crowe played him in the 2005 film.
Two details the story tends to skip. The venue was nicknamed the Graveyard of Champions because no reigning champion had ever successfully defended a title in it, a fact anybody could’ve looked up before a bet was struck. And the fight was scrappier than the legend: BoxRec’s record of the bout shows referee Johnny McAvoy taking three rounds off Baer for low blows or backhanding, with the Associated Press scoring it seven rounds each and one even. Baer went home with $88,805 and Braddock with $31,244 out of a net gate of $169,074.
Four More Without a Surviving Number
Gene Tunney outpointed Jack Dempsey over ten rounds at Philadelphia’s Sesquicentennial Stadium on 23 September 1926, before a crowd ESPN puts at 120,557, then beat him again 364 days later at Soldier Field in the fight remembered for the long count.
Leon Spinks was 6-0-1 when he took a fifteen-round split decision from Muhammad Ali in Las Vegas on 15 February 1978. It was his eighth professional bout and it made him heavyweight champion at 24.
Max Schmeling floored Joe Louis in the fourth and stopped him in the twelfth at Yankee Stadium on 19 June 1936, handing Louis the first loss of his professional career. Louis knocked Schmeling out in the first round when they met again two years on.
Randy Turpin outworked Sugar Ray Robinson over fifteen rounds at Earls Court on 10 July 1951. Robinson arrived at 129-1-2 and at the tail end of a long European tour of bouts and appearances. He took the title back 64 days later.
No contemporary price survives for any of those four in a form worth quoting. That’s why they get four paragraphs here instead of four sections.
What the Biggest Boxing Upsets Do Not Prove
Four fights with a documented number, spread across 84 years. Across the same stretch the favourite won the overwhelming majority of championship fights, and nobody has ever written that list.
Boxing is close to the worst sport available for building a sample. A heavyweight fights two or three times a year at the outside. No schedule exists, no league, no auditable archive of closing prices, and the fights that get made are picked by promoters partly for how one-sided they look on paper. Douglas-Tyson had one liquid price in the entire country. Ruiz-Joshua carried three different prices at three books on the same night. You can’t back-test either one.
What the record does show, fairly consistently, is that the information was usually sitting there. Liston’s shoulders, Tyson’s camp, a venue where no reigning champion had ever held onto a belt. Available and unpriced is a real observation. Available and profitable is a much larger claim, and nothing on this page establishes it. Boxing also carries variance high enough that a single punch resolves the whole question, which cuts against long-run reasoning rather than for it. If backing underdogs feels like the obvious conclusion after reading this far, our page on why underdogs feel wrong covers where that pull comes from.
Where the Number Actually Comes From
Vaccaro kept lengthening Douglas because Tyson money wouldn’t stop arriving, and he wanted it to. It didn’t stop. People laid $54,000 to win $2,000, then $93,000 to win $3,000, then $168,000 to win $4,000, and every one of those tickets was worthless by the tenth round.
So the Mirage booked around $13 million on the biggest upset in the sport’s history and won roughly $400,000 on it. The one book in Nevada willing to price the fight got the result completely wrong and still came out ahead, because almost everyone who bet it had taken the short end at a price that paid them almost nothing.
The man who laid $168,000 to win $4,000 told Vaccaro he’d be back to collect. He never came back.
