Best Olympic Upsets Ever

These aren't flukes. Every upset on this list required the underdog to perform at or beyond their ceiling while the favorite fell short of theirs.

Key Insights

• The Miracle on Ice is the greatest Olympic upset in history not just because of the talent gap but because of the Cold War context that made the Soviet hockey team represent something far beyond sport
• Rulon Gardner defeating Aleksandr Karelin in 2000 is the most statistically improbable Olympic result ever, with the defending champion having not conceded a single point in six years before the final
• Billy Mills winning the 10,000 meters in 1964 is the most purely athletic upset on the list, with a runner who had never broken 29 minutes outrunning the world record holder in the Olympic final

Miracle on Ice: USA 4-3 USSR, 1980

The greatest upset in Olympic history, and the one that required the least context to understand and the most to fully appreciate.

The Soviet Union's hockey program had dominated international competition for years. They had beaten the NHL All-Stars. They had won four consecutive Olympic gold medals. The US team was composed of college players with an average age of 22 assembled by coach Herb Brooks months before the Games. Nobody genuinely believed the Americans could win.

What makes the Miracle on Ice more than just an upset:

• The Cold War context turned a hockey game into something that felt geopolitical
• The US team's 4-3 win in the semifinal required overcoming a Soviet team that had routed them 10-3 in an exhibition three days before the Games began
• The result produced one of the most replayed broadcast moments in sports history, with Al Michaels asking "Do you believe in miracles?" as time expired

Bleacher Report puts this at or near the top of every Olympic upsets list, and the reasoning is straightforward: the gap between what was expected and what happened was larger here than in any other Olympic competition.

Rulon Gardner Beats Aleksandr Karelin, 2000

The most statistically improbable result in Olympic history, and an upset that required defeating someone who had not lost a match in thirteen years.

Karelin was the greatest Greco-Roman wrestler in the sport's history. He had won three consecutive Olympic gold medals. He had not conceded a single point in six years of international competition. He had never been taken down in an Olympic match. Rulon Gardner was an American farmer from Wyoming who was not considered a realistic threat to any of those records.

Gardner won 1-0 on a technical point when Karelin lost his grip during a hold. The scoreline understates what happened:

• The only point in the match came from the unbeatable man making the first significant error of his competitive career at the worst possible moment
• Gardner had been preparing specifically for this match but had never looked like someone who could produce this outcome
• Karelin's reaction after the loss, a quiet processing of something he had not previously needed to prepare for, was itself one of the most significant moments of the match

Bleacher Report notes the six-year no-point streak specifically because it makes the 1-0 score feel more improbable than any high-scoring upset could.

Billy Mills Wins the 10,000 Meters, 1964

The most purely athletic Olympic upset, and the one that required a runner to perform so far beyond his previous best that the result was genuinely inexplicable in real time.

Mills had never broken 29 minutes for 10,000 meters before the 1964 Tokyo Olympics. Ron Clarke held the world record and was the clear favorite. Mills finished in 28:24, set an Olympic record, and outsprinted Clarke and Mohamed Gammoudi in the final straight after being pushed wide with 200 meters remaining.

The specific quality of the Mills upset that separates it from the others on this list:

• The improvement from his personal best to his Olympic winning time was substantial enough that the result looked like a timing error to some broadcasters initially
• The physical disadvantage he overcame in the final straight, being pushed wide and having to accelerate from a compromised position, added a layer of difficulty that the time alone doesn't capture
• Mills remains one of the few athletes to win an Olympic gold medal in an event they had never previously competed at the elite level in

Chad Le Clos Beats Michael Phelps, 2012

The moment when the most decorated Olympian of all time got beaten in his best event, and the specific way it happened made it unforgettable.

Phelps was the favorite in the 200-meter butterfly in London. He had won the event in both 2004 and 2008. South Africa's Chad le Clos swam a faster final twenty-five meters and touched the wall first, leaving Phelps fourth in a race he was supposed to win.

The aftermath extended the story beyond the race itself. Le Clos's father Bert's celebration was captured on camera and became one of the most replayed sporting reaction moments of that Games, adding an emotional layer that purely athletic upsets don't always generate.

Iouri Podladtchikov Beats Shaun White, 2014

The Winter Olympic upset that required the underdog to land a trick the favorite hadn't included in his routine, in the event the favorite had won twice before.

Shaun White was the two-time defending Olympic halfpipe champion and the clear favorite in Sochi. Podladtchikov, known as the iPod, landed the Yolo flip, a cab double cork 1440 that White had not attempted, and scored 94.50 to White's 90.25. White finished fourth.

What makes this upset specifically interesting beyond the result:

• Podladtchikov won by doing something more difficult rather than by the favorite performing below their standard
• The Yolo flip was a genuine technical advancement in the sport rather than a risk that happened to pay off
• White's fourth-place finish in his signature event produced the specific kind of result that reframes an entire career narrative in the span of one run

The greatest Olympic upsets share one quality: they required the underdog to perform at the absolute ceiling of what they were capable of, at the exact moment the favorite was at their most beatable. When both of those things happen simultaneously in an Olympic final, the result stays in the conversation forever.

FAQ

What is the greatest Olympic upset of all time?

The Miracle on Ice is the consensus answer because the combination of the talent gap, the Cold War context, and the cultural impact makes it larger than any other upset in the Games' history.

How had Karelin gone thirteen years undefeated before Gardner?

Through a combination of dominant physical strength, technical mastery of the reverse body lock, and a competitive consistency that produced results in every major international competition. No one had found a way to neutralize his strengths before Gardner's specific preparation for that match.

Did Billy Mills ever repeat his 1964 performance?

He remained a competitive long-distance runner but never replicated the specific improvement from his pre-Olympic personal best to his winning time. The 1964 performance stands as an isolated peak that his subsequent career didn't approach.

Is the Miracle on Ice the most watched Olympic upset?

By modern standards, probably not, since the broadcast reach of the 1980 Games was limited compared to current coverage. But it's the most culturally embedded Olympic upset in American sports history, which is a different kind of reach.

Was Shaun White's 2014 loss considered a genuine upset at the time?

Yes, though the specific framing was that Podladtchikov had been developing the Yolo flip and was considered capable of challenging White. The gap between "capable of challenging" and "winning by landing a trick the champion didn't attempt" is where the upset framing lives.
