What if you bet $100 on PSG to win the 2025 Champions League?
A $100 bet on PSG at its lowest price of 1.2¢ (8 Oct 2024) would have paid $8,333 when the market resolved, a 83x return. A week before the result, at 58.65¢, the same $100 would have paid $171.
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 PSG 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 Champions League Winner market opened in September 2024, as the competition moved to a new 36-team league phase, and listed every club in it. It resolved to the winner of the final.
Paris Saint-Germain's season was rocky early. The club finished 15th in the league phase and had to win a play-off against Brest to reach the round of 16. It then beat Liverpool on penalties, Aston Villa in the quarter-finals and Arsenal in the semi-finals. The lowest prices in the data come from the autumn of 2024, when PSG's league-phase form was poor and a place in the knockout rounds looked at risk.
In the final on May 31, 2025 at the Allianz Arena in Munich, PSG beat Inter Milan 5–0 and won the trophy for the first time. PSG's shares settled at $1 and every other club's at $0. The timeline below marks the Liverpool tie, the semi-final second leg and the final.

The other side: $100 on Inter Milan
$0
Inter Milan peaked at 41.95¢ on 27 May 2025. At that price $100 buys 238 shares, which would have felt like a strong bet at the time. Inter Milan 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 PSG have made on Polymarket?
- At its lowest price of 1.2¢ (8 Oct 2024), $100 buys 8,333 shares. Each winning share paid $1, so the bet would have returned $8,333, a profit of $8,233. One week before the result (58.65¢) the same $100 would have returned $171. These are hindsight figures before fees.
- What were the odds on PSG a week before the result?
- Seven days before the last price in our data, PSG traded at 58.65¢ on 24 May 2025, an implied chance of 59%. That is decimal odds of 1.71 (American −142). One day before the result the price was 59.55¢.
- What would $100 on Inter Milan have been worth?
- Nothing. Inter Milan peaked at 41.95¢ on 27 May 2025, a price at which $100 buys 238 shares, but Inter Milan 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 31 May 2025), 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 “Champions League Winner”, from 18 Sep 2024 to 31 May 2025. 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.
