World Cup 2026 — how the market priced it
Real money, not pundits. Through the 2026 tournament this page tracked the win probability the crowd was actually paying for. The tournament is finished, so it is now a record of two things: what the market priced before the final, and what happened.
Written2026-07-28, after the final. The prices below were recorded before kickoff and have not been altered since; the result was added only once it had been verified from primary sources.
What the market priced before kickoff
The final, Spain v Argentina at MetLife Stadium, 19 July 2026. The single largest market in either venue's history: Kalshi's contract on this match passed $1.27B in trading volume before kickoff, against >$25B traded across all World Cup contracts.

Publisher-reported: Fortune, 2026-07-17 — "As of mid-day Friday, bets on Kalshi showed the Spanish team with 61% odds". Not a same-instant reading.
Argentina

Read directly from Polymarket's public Gamma API (World Cup Winner event, outcomePrices).
Each figure is recorded exactly as the venue carried it. Kalshi has a price for Spain only: no Argentina figure was published alongside it, so none is shown here and none is derived by subtracting 61% from 100. The two venue readings are also about two days apart, which makes the difference between them indicative rather than a simultaneous quote.
What happened
Spain · 1–0 · after extra time (AET)
Ferran Torres scored in the 106th minute, assisted by Nico Williams; Argentina played extra time a player down after Enzo Fernández was sent off (second yellow) in second-half stoppage time.
Recorded in the accuracy ledger 2026-07-20 · verified against two independent primary sources before it was written there.
How to read this
Those are two separate facts — the price each venue carried before kickoff, and the result — and they are recorded separately on purpose. Setting them side by side is not a scorecard. A favourite winning one match is equally consistent with a well-calibrated market and a badly-calibrated one, so nothing here shows that the market was right; a single event has no error bar. Whether these prices are worth watching is a question only a series can answer, which is why each one is recorded before its event resolves, in one place.

The live board, for what it is now
The winner feed this page was built on is still connected and still polls every 60 seconds. With the tournament finished there is no open winner race left for it to price, so it usually returns nothing at all. It is left here, saying so, rather than quietly removed.
No World Cup winner markets are returning data. The tournament finished with the 19 July final, so there is no live winner race left to price — see the full predictions board for markets that are still open.
