How Accurate Were the Group Stage Predictions?
Prediction markets were mostly accurate during the group stage. Most favorites won their groups or advanced, while a few teams caused unexpected shifts in the odds.

Biggest Group Stage Surprises
While most favorites advanced as expected, many teams outperformed their pre-tournament projections.
Morocco, Bosnia-Herzegovina, Canada, Paraguay, Cape Verde and Japan emerged as some of the biggest surprises of the group stage, each securing a place in the knockout rounds despite lower initial expectations.
Their strong performances not only reshaped the tournament bracket but also triggered important shifts in prediction market prices as their odds improved throughout the group stage.
The Knockout Stage: Why Predictions Get Harder
Once the group stage ends, the tournament becomes single elimination. One loss ends a team's run, which means World Cup winner probabilities, futures odds, and "to advance" markets can swing after every match.
From this point, market attention moves from group winners to quarterfinals and semifinals qualifiers, lifting the trophy, and individual awards like the Golden Boot. Because a single result can eliminate a contender, prices move faster and further than they do in the group phase.
Prediction Markets: Trading on World Cup Outcomes
Prediction markets let you trade contracts on real-world events rather than place traditional sportsbook bets. As the probability of an outcome changes, contract prices move in real time, giving you the flexibility to enter or exit positions before the event is settled.
Regulated platforms like Kalshi and Polymarket typically offer World Cup markets including:
- World Cup Winner
- Quarterfinal and Semifinal Qualifiers
- Individual Match Winners
- Golden Boot Winner
- Continent to Win the World Cup
Instead of betting against the house, you're trading based on market sentiment. If you believe a team's chances are undervalued, you can buy contracts early and potentially sell them later if prices rise before kickoff or the final whistle.
Kalshi vs. Polymarket for World Cup Predictions
The World Cup is one of the biggest events on prediction market apps, with traders reacting to every result, goal, and standout performance.
Kalshi and Polymarket offer many of the same World Cup betting markets, including tournament winners and teams advancing through the knockout stage. The main differences come down to the platforms themselves: fees, market depth and liquidity, user experience, and if you prefer trading on desktop or mobile.
If you enjoy following tournament probabilities as they change throughout a competition, both platforms offer an interesting alternative to traditional sportsbook odds.
Sportsbook Futures
The best sportsbooks and betting sites in the US, like bet365, Fanatics Sportsbook, BetMGM, and FanDuel, update the future odds every day during the tournament. These lines reflect team strength, draw difficulty, travel factors across the host countries, and the expanded advancement format.
What Was Available on Prediction Markets During the World Cup
Throughout a World Cup, prediction markets and sportsbooks run a broad range of markets that evolve as the tournament progresses. Two of the most closely followed are the outright winner market and the Golden Boot race. Here's what those markets looked like during the 2026 tournament.
Outright Winner (Top Contenders)
The pre-tournament heavyweights stayed near the top of the outright winner market, though each team's path through the bracket shaped how its price moved. In 2026, contenders such as France, Argentina, Spain, and England headlined the market, with sides like Norway and Morocco featured as longer-shot options.
You can see how these markets were priced in the 2026 Men's World Cup Odds.
Golden Boot (Top Goalscorer)
The Golden Boot market tracks the race for the tournament's top scorer. In 2026, names like Lionel Messi, Kylian Mbappé, Erling Haaland, and Harry Kane featured among the contenders, and prediction markets and sportsbooks sometimes ranked them in a different order.
How to Read World Cup Odds
Odds and market prices are just probabilities expressed in different formats:
- Implied probability (%): how likely the market thinks an outcome is.
- American odds (+/–): a minus number (e.g., –200) marks a favorite; a plus number (e.g., +250) marks an underdog with a larger potential payout.
The specific numbers move constantly as matches are played, so treat any single price as a snapshot rather than a fixed value. For forecasting, what matters most is how prices shift in response to new information.
You can use the Action Network's Prediction Markets Calculator to covert the implied probability into the familiar American odds.
World Cup Prediction Tips
No one can predict soccer with certainty. But prediction markets, sportsbook futures, and data models give you a structured way to estimate probabilities instead of relying on guesswork. Favorites usually advance, surprises always emerge, and the knockout stage is where forecasts — and market prices — are tested hardest.
A few principles tend to hold up tournament after tournament:
In the group stage:
- Give favorites room to recover. Strong teams have several matches to advance, so one bad result rarely knocks them out. A shaky opener isn't always the value it looks like.
- Watch for motivated underdogs. Once qualification is settled, underdog teams will still fight to advance.
- Respect the surprises. Nearly every World Cup produces teams that outperform their projections. Rising odds during the group stage are often the first signal.
In the knockout stage:
- Look beyond recent results: A big group-stage win doesn't always carry over to the knockout rounds. Matchups and playing styles matter just as much.
- Understand the extra-time rules: If a match is tied after 90 minutes, it goes to extra time and, if needed, a penalty shootout. Keep that in mind when predicting on match winners versus teams to qualify.
- Monitor injuries and suspensions: Missing one key player can make a huge difference when every match is win-or-go-home.
- Watch the bracket: As teams advance, the path to the final becomes clearer. Futures and "to qualify" markets can move quickly after each knockout match.
