Can Argentina Defend Their Title? 2026 World Cup Odds and Messi's Last Dance
Argentina are the defending world champions, and they still have Messi — but the prediction market does not see them as the top favorite for 2026. On the eve of kickoff, Argentina’s win probability sits around 8%, sixth in the field, and it’s been drifting downward all month. If this really is Messi’s last World Cup, the story writes itself; but the data tells us this is a holder with genuine upset potential, not the team most likely to win.
What’s Argentina’s win probability right now?
Live data from Polymarket (pre-tournament):
| Rank | Team | Win probability |
|---|---|---|
| 1 | Spain | ~17% |
| 2 | France | ~16% |
| 3 | England | ~11% |
| 4 | Portugal | ~10% |
| 5 | Brazil | ~9% |
| 6 | Argentina (holders) | ~8% |
Major sportsbooks agree — Argentina around +1000 (implied ~9%), also at the back of the first tier. Notably, Argentina’s probability has slid from around 11% to 8% over the past month. The market’s confidence in them is cooling.
Reigning champions — so why not a favorite?
The market gives three main reasons:
- Squad depth and age. Key players (especially Messi) are older, and the bench is seen as thinner than Spain’s or France’s.
- Rivals on the rise. Spain, France, and England are in better form and riding academy talent, pushing Argentina down the order.
- Defending is hard. Back-to-back titles are extremely rare in World Cup history, so the market naturally discounts the holders.
Messi’s last dance: does it move the odds?
Yes, but probably less than you’d think. A superstar lifts a team’s profile and some of its win probability (leadership, the ability to decide a game), but a mature prediction market weighs overall squad and current form — it won’t pay a premium for sentiment. Messi’s experience and pull are a plus, but the market has already priced in his age risk.
In other words: sentiment is sentiment, and price is price. Messi’s last dance makes this Argentina side more compelling, but to judge whether they’ll win, you still have to read the cold probability.
What does 8% mean?
8% is roughly a 1-in-12 chance. That sounds low — but in a 48-team World Cup, it’s still first-tier, with a real shot. So the right read is: Argentina are neither out of it nor anywhere near safe. Treat 8% as “an upset candidate worth watching,” not “champions-in-waiting,” and you’re thinking about it correctly.
How to track it from here
Argentina’s probability will jump around in real time through the group and knockout stages — the key is the trend:
- If Argentina’s probability starts climbing after kickoff, the market is warming to them again (strong performances, or rivals stumbling).
- If it keeps falling, their title defense isn’t being backed.
