The Biggest Upsets in Sports Betting History and What We Can Learn from Them

Table of Contents

Sports betting is an enthralling venture that captivates millions around the globe. It facilities a unique dynamic: people betting against the odds and unknown outcomes in hopes of making huge wins. 

But sometimes, in a surprising twist of fate, underdogs triumph over champions, overturning predictions and causing enormous losses for bookies. These startling upsets have shaped sports betting history, offering valuable lessons to both avid bettors and occasional punters. 

Let’s explore some of the most significant upsets and the indispensable insights they provide.

1. The Miracle on Ice (1980)

Dubbed the “Miracle on Ice,” this was perhaps the most shocking upset in sports history. The unfancied US hockey team triumphed over the heavily favoured Soviet Union team at the 1980 Winter Olympics. The Soviet Union had dominated international ice hockey for over two decades, and bookmakers placed minuscule odds on their victory. 

A $100 bet on the Soviets would yield a paltry $1.20. On the other hand, a winning wager on the USA team would land a whopping $1000 return. The shocking outcome had profound implications, teaching bettors that even the most dominant teams can be toppled. It underscores the importance of never underestimating the underdog.

2. Buster Douglas Defeats Mike Tyson (1990)

In 1990, undefeated and undisputed heavyweight champion Mike Tyson faced off against James “Buster” Douglas. Tyson, in splendid form, was expected to make light work of Douglas. Some casinos refused to take odds on the fight due to Tyson’s overwhelming dominance, and the few brave ones, like Mirage, offered 42 to 1 odds favouring Tyson. 

Miraculously, Douglas knocked out Tyson in the 10th round to claim the heavyweight title. This outcome is a sober reminder that in sports, anything can happen, and bettors should be prepared for unforeseeable outcomes.

3. Leicester City Wins the Premier League (2015-2016)

Leicester City winning the English Premier League in the 2015-2016 season is deemed the greatest long-shot victory in the history of betting. The club were a relegation candidate at the start of the season with almost insurmountable odds of 5000 to 1 to win the title. A punter who risked a $20 bet on Leicester’s victory pocketed a hefty $100,000 after the Foxes clinched the title. This episode underlines the value of intuition and betting on long shots in moments of uncertainty.

4. New York Giants Upset New England Patriots (Super Bowl XLII, 2008)

In the 2008 Super Bowl XLII, the New England Patriots were expected to cap a perfect season and emerge victorious over the New York Giants. The Patriots had maintained a perfect record of 16 wins in the regular season. As such, bookies placed 12-point odds favouring Patriots. However, the Giants sprang an upset, defeating the Patriots 17-14. 

The outcome underscores the unpredictable nature of sports, reaffirming the importance of analysing team form beyond basic statistics.

5. Ronda Rousey’s Loss to Holly Holm (UFC 193, 2015)

Ronda Rousey, undefeated in her career, entered UFC 193 as an intense favourite with odds ranging from -1500 to -2000. Holly Holm’s victory odds were +800. However, Holm stunned the world by beating Rousey via knockout in the second round. 

The upset offers a valuable lesson to bettors that even strong favourites can falter, and the surprises are what makes sports betting so captivating.

6. Greece Wins the Euro 2004

Before Euro 2004, Greece was ranked 35th in the world and given 150 to 1 odds to win the tournament. Greece triumphed against all odds and clinched the title, shocking both spectators and betting houses alike. 

The victory proved that rankings don’t define teams and passion, teamwork, and tactics can overcome odds, which is an invaluable lesson for sports bettors.

7. St. Louis Cardinals Win the World Series (2011)

The Cardinals were 500 to 1 outsiders to win the World Series in 2011. With less than a month left in the regular season, the team had only a 1.3% chance of making the playoffs. Nonetheless, they ended up winning, ending the season on a high note. 

This serves as a poignant reminder in sports betting that nothing is over until it’s over, emphasising the significance of patience and perseverance.

8. Appalachian State Defeats Michigan in College Football (2007)

In college football, Michigan was a 33-point favourite against Appalachian State in a 2007 game. However, in a dramatic turn of events, Appalachian State won 34-32. This upset underscores that favorites sometimes crumble under pressure and that sports bettors should consider psychological factors during wagering.

9. New York Jets Win Super Bowl III (1969)

In 1969, the undervalued New York Jets beat the Baltimore Colts on their way to winning Super Bowl III. The Colts were highly favoured, and the Jets were given 18-point underdogs; however, the Jets turned the tables and claimed a 16-7 victory. This major upset expanded horizons for bettors, demonstrating that even the highest-rated favourites can falter.

10. Denver Nuggets Shock Seattle SuperSonics (1994)

In 1994, NBA’s Seattle SuperSonics held an impressive 63-19, number one seeded when they encountered the eighth-seeded Denver Nuggets. The Sonics entered the playoff series as favourites, but astonishingly, the Nuggets won in five games. 

This result is a vivid example that dominant teams can falter against low-ranked competitors given the right circumstances, encouraging bettors always to look beyond the obvious factors when placing bets.

11. Steven Bradbury’s Unexpected Gold Medal (2002)

At the 2002 Winter Olympics, Australia’s Steven Bradbury won a gold medal in short-track speed skating, despite heavy odds against him. All his competitors crashed just before the finish line, allowing him to cruise to an unexpected victory. 

This profound example reminds sports bettors of the unpredictable nature of sports, and that luck can play a major role in outcomes.

12. Roberta Vinci Beats Serena Williams (2015)

Serena Williams was favorited by -3000 odds to win the 2015 U.S. Open semi-final against Roberta Vinci. However, Vinci managed to shock the tennis world with her incredible 2-1 victory over Williams. Bettors learned from this upset never to take for granted, even the most dominant athletes.

13. Joe Namath’s Guarantee (Super Bowl III, 1969)

Joe Namath’s audacious guarantee that his 18-point underdog team, the New York Jets, would beat the Baltimore Colts in Super Bowl III was bold. His prophesy held firm as the Jets secured a historic 16-7 triumph against the Colts, proving again to bettors the value of self-belief and determination and that declarations can indeed play out in reality.

14. Cleveland Cavaliers Comeback in NBA Finals (2016)

The Golden State Warriors were touted as near-certain winners of the 2016 NBA Finals with a 3-1 lead over the Cleveland Cavaliers. However, Cavs orchestrated an improbable comeback to claim a 4-3 victory. This upset taught bettors to never rule out a determined team, no matter how dire their straits seemingly are.

15. NC State Wins NCAA Basketball Championship (1983)

The NC State Wolfpack, led by their inspiring coach, Jim Valvano, won the 1983 NCAA tournament in an extraordinary fashion against the heavily favoured Houston Cougars. They attained the victory thanks to a last-second dunk, a seminal moment considered one of the greatest in sporting history. 

This event serves as a timeless illustration of how miracles can happen in sports, reminding bettors that surprises lurk around every corner, even until the final moment.

16. Japan Defeats South Africa at the Rugby World Cup (2015)

At the 2015 Rugby World Cup, Japan managed a triumph over South Africa, a two-time World Cup winner, in a surprising 34-32 win. Japan entered the game as 66-1 underdogs but pulled one of the greatest upsets in rugby history. 

This dramatic turn of events offered a hard lesson on the volatile nature of sports and, consequently, betting, as even the most seemingly assured results can be undone.

17. Chaminade Defeats Virginia in NCAA Basketball (1982)

In a 1982 college basketball match, Division II school Chaminade faced off against the top-ranked University of Virginia. Virginia was favoured so heavily that Vegas did not even offer a betting line for the game. 

However, Chaminade caused shockwaves by winning 77-72. This dramatic upset reminded bettors that no outcome is guaranteed in sports, and David vs. Goliath battles can sometimes favour the underdog.

18. Donerail Wins the Kentucky Derby (1913)

Horse racing boasts a long list of upsets, and one of the most famous ones was Donerail in the 1913 Kentucky Derby. Facing staunch competition from better-pedigreed horses, Donerail started the race as a 91-1 outsider. In a surprising twist of events, the stallion romped home first, rewarding the handful of brave punters who had staked on him with a huge payout. 

The lesson here for bettors: while long shots are just that, they sometimes come in and can provide a significant return on a small wager.

What Can We Learn From These Sports Betting Upsets?

One thing is clear: upsets don’t just undo predictions; they also upend conventional wisdom in sports betting. By analysing these incredible upsets, several key takeaways for bettors emerge. 

1. Always Account for Underdogs: Miracles can happen in sports. No team is too weak to overcome an apparently superior opponent, as evidenced by the Miracle on Ice and the surprising victory of Leicester City in the Premier League. This teaches us to always consider the underdogs in your betting strategy.

2. Don’t Rely Solely on Statistics: While statistics and past performances are useful, they alone can’t determine the outcome of a sporting event. Other factors, such as motivation, team synergy, individual brilliance, and even luck, also come into play. This lesson is seen clearly in the victory of the New York Giants over the New England Patriots.

3. Anything Can Happen: The unpredictability is one of the allures of sports betting. Even strong favourites can falter, as the Patriots did in Super Bowl XLII or Ronda Rousey did at UFC 193. This highlights the importance of managing your bankroll wisely and being prepared for eventual losses.

4. Intuition Can Pay Off: Sometimes, gut feelings, intuition, or an informed hunch can lead to successful bets, as some fortunate punters proved when they backed Leicester City to win the Premier League. 

5. Never Underestimate Psychological Factors: As we can learn from Michigan’s unexpected defeat to Appalachian State, psychological factors such as dealing with pressure and high expectations of victory could tip the scale in an underdog’s favour.

6. Patience Pays: The victory of St. Louis Cardinals teaches that betting, like the sports it involves, is a game of endurance where the situation may change dramatically in the closing stages.

By learning from these sports betting upsets, bettors can gain valuable insights to improve their betting strategies and decision-making processes. While it’s impossible to predict every upset, a bettor can mitigate risks, manage their bankroll effectively, and potentially spot great value bets. After all, as these iconic upsets have shown us, that’s why they play the games. Anything can happen.
