What if you bet $100 on Spain to win the 2026 World Cup?
A $100 bet on Spain at its lowest price of 10.05¢ (2 Jul 2026) would have paid $995 when the market resolved, a 10x return. A week before the result, at 20.55¢, the same $100 would have paid $487.
Hindsight only. Nobody knew the result at the time, and early prices were often thin. Past results do not predict future ones, and you can lose what you trade.
What $100 on Spain would have become
A share costs its price in dollars (40¢ is $0.40) and pays $1 if the outcome wins, so a $100 bet at 40¢ buys 250 shares and returns $250. Here is that sum at the key moments of the market.

What happened and why the odds moved
Polymarket's World Cup Winner market opened in July 2025, almost a year before the first match, and became one of the largest markets the platform has hosted. The 2026 tournament, held in Canada, Mexico and the United States from June 11 to July 19, was the first with 48 teams.
Spain was the market favourite for most of the year, with France, England, Portugal and Argentina close behind. The four top-ranked teams in the FIFA men's ranking, Argentina, Spain, France and England, all reached the semi-finals. Spain beat Portugal 1–0 in the round of 16 and France 2–0 in the semi-final.
The final was played at MetLife Stadium in New Jersey on July 19, 2026. Spain beat Argentina, the defending champions, 1–0 after extra time to win its second World Cup, 16 years after its first. Spain's shares then settled at $1 and every other team's shares at $0. The timeline below marks the start of the tournament, the round of 16, the semi-final and the final.

The other side: $100 on Argentina
$0
Argentina peaked at 42.15¢ on 16 Jul 2026. At that price $100 buys 237 shares, which would have felt like a strong bet at the time. Argentina did not win, so every one of those shares resolved to $0.
Every market has losers, and only one outcome pays. The calculator above shows the best case in hindsight; picking an outcome before the result is known can go the other way.

Common questions
Answers use this market’s price history. See how Polymarket odds work if the prices are new to you.
- How much would $100 on Spain have made on Polymarket?
- At its lowest price of 10.05¢ (2 Jul 2026), $100 buys 995 shares. Each winning share paid $1, so the bet would have returned $995, a profit of $895. One week before the result (20.55¢) the same $100 would have returned $487. These are hindsight figures before fees.
- What were the odds on Spain a week before the result?
- Seven days before the last price in our data, Spain traded at 20.55¢ on 13 Jul 2026, an implied chance of 21%. That is decimal odds of 4.87 (American +387). One day before the result the price was 59.05¢.
- What would $100 on Argentina have been worth?
- Nothing. Argentina peaked at 42.15¢ on 16 Jul 2026, a price at which $100 buys 237 shares, but Argentina did not win and those shares resolved to $0. A winning share pays $1 and a losing share pays nothing.
- Can I still bet on this market?
- No. This market has already resolved (our price history ends on 20 Jul 2026), so its shares can no longer be traded. Polymarket lists new markets on similar questions, such as the Champions League winner odds on this site. Taker fees on current markets (see our Polymarket fees guide) would take a small slice of any return, and past results do not predict future ones.
How we calculate this
Data. Prices come from Polymarket’s public price-history endpoint (documentation), one sample every 12 hours for the winning outcome of “World Cup Winner”, from 3 Jul 2025 to 20 Jul 2026. The price of a share is also the market’s implied probability.
Formula. Shares = amount ÷ price. Payout = shares × $1, because a winning share pays $1. Profit = payout − amount. The return is $1 ÷ price. Decimal odds are the same number.
Key moments. The opening price is the sample about a day after the first one, because the first samples are often a placeholder. The lowest price is the lowest sample since then. The 30-, 7- and 1-day prices are the last sample at or before that many days ahead of the final sample, which is when the result was known or, for single-game finals, the last price before the deciding game began.
Limits. Samples every 12 hours can miss a brief low or high. A price is a quote, not a guaranteed fill: real orders pay the spread, can move the price in thin markets, and early prices in a new market are often thin. Fees are not included. The figures describe the past and are not advice.
