The UEFA Champions League is back for the 2026/27 season with 36 teams from across Europe battling to become the continent's leading club side come the final at the Metropolitano in Madrid on Saturday, June 5, 2027.
But who do prediction markets think will lift the trophy?
Unlike traditional Champions League betting odds, prediction markets on leading platforms Kalshi and Polymarket offer a constantly updated view of the teams most likely to win the competition, with prices changing as traders react to results, the draw for the knockout rounds, major injuries and other developments throughout the season.
Paris Saint-Germain have been the undisputed kings of Europe in the past two seasons, demolishing Italian side Inter Milan 5-0 in the 2025 final before dispatching Premier League champions Arsenal via penalties in Budapest following a 1-1 draw in the 2026 showpiece game.
The French side are among the leading contenders once again, alongside the likes of European giants Real Madrid, Barcelona, Arsenal and Bayern Munich, although the prediction markets' outlook can change significantly as the tournament progresses.
This page tracks the major Champions League prediction markets, including the outright winner and Golden Boot, with prices and probabilities updated as the competition develops.

Champions League winner prediction markets
The Champions League winner prediction market shows how traders continually assess each club's chances of winning the trophy as the competition develops.
Ahead of the tournament, more than $25 million had been traded on Polymarket's 2027 Champions League winner market, with Barcelona currently leading the way.
The five-time winners haven't won the tournament since 2015, but Barcelona are currently given the highest probability of lifting the trophy across both Polymarket and Kalshi.
Last year's runners-up Arsenal, record 15-time winners Real Madrid and German giants Bayern Munich are all grouped closely as leading contenders, as are holders PSG as they go for a three-peat success.

Champions League Golden Boot prediction markets
The Champions League Golden Boot prediction market offers another long-term view of which players are most likely to finish as the tournament's leading goalscorer.
In Kalshi's Champions League Golden Boot market, the leading candidates broadly align with those teams expected to challenge for the trophy, with Real Madrid's Kylian Mbappé around 23%, Bayern Munich striker Harry Kane at 17% and Manchester City star Erling Haaland around 14%. Trading in that market is thin this early in the season, so those prices are looser than the winner market's.
The top scorer market will likely fluctuate sharply once matches begin to produce meaningful scoring data. A player who starts the tournament quickly can see their probability rise, while injuries, rotation or an early exit can cause it to fall sharply.

Champions League league phase and knockout prediction markets
Prediction markets also offer a more detailed view of how teams are expected to perform at different stages of the Champions League, from the league phase through to the knockout rounds.
Champions League league phase prediction markets
Kalshi's Champions League league phase market gives traders the chance to predict which teams will finish highest in the 36-team table after each club plays eight matches.
Again, Barcelona lead the way in this prediction market, ahead of Real Madrid, Arsenal and Bayern Munich. Arsenal topped the league phase table last season.

Champions League knockout round prediction markets
Polymarket also offers markets asking which stage of the Champions League knockout rounds a team will reach, including the round of 16, quarter-finals and semi-finals.
These markets provide a different perspective from the outright winner market. A club may have a relatively low probability of winning the Champions League but a much higher chance of reaching the quarter-finals, while a leading contender could face a more difficult route through the knockout rounds.
Tracking these stage-by-stage probabilities can therefore provide another indication of how highly prediction-market traders rate each team as the competition progresses.

Kalshi vs Polymarket: Comparing Champions League prediction markets
The two leading Champions League prediction markets broadly agree on the leading contenders, with Barcelona and Arsenal among the clubs carrying the highest probabilities at the start of the tournament.
However, comparing Kalshi and Polymarket can reveal where traders on the two platforms disagree, and tracking those differences as the season progresses can provide another useful layer of analysis.
For example, if Barcelona move from 19% to 25% on Polymarket following a strong run of results, that suggests traders on the platform have reassessed the club's chances of winning the Champions League. If Kalshi moves by a similar amount, it suggests traders on both platforms have reached a broadly similar conclusion based on the latest information they have available.
But what if the markets move in different directions?
For example, if Barcelona rise from 19% to 25% on Polymarket but remain at 19% on Kalshi, the gap could indicate that traders on one platform have reacted more strongly to Barcelona's results or other developments.
It does not necessarily mean that either market is wrong. Differences in liquidity, trading activity, fees and the composition of traders on each platform can all influence prices.
A small difference may simply reflect normal market fluctuations, but a persistent or widening gap could highlight a genuine difference in how traders on the two platforms assess a team's chances.
How Champions League prediction markets change
Champions League prediction markets can change significantly as new information and data points emerge throughout the season, giving traders a constantly evolving view of which teams and players are on track for success.
The league phase provides the first major opportunity to reassess each club's chances, as results and performances begin to provide a clearer picture of their prospects in Europe. The Champions League knockout draw will provide another important turning point, with each team's potential route to the final becoming clearer and the strength of the opponents standing between them and the final in Madrid easier to assess.
Further changes can come from January transfers, major injuries, knockout-round results and unexpected exits from the competition. A team that starts the season among the favourites could quickly see its Champions League prediction market probability fall after a poor run of results, while an outsider could gain momentum as its chances of reaching the latter stages improve.
This page will be updated throughout the 2026/27 Champions League season, tracking changes in the major prediction markets on Kalshi and Polymarket, including the outright winner, Golden Boot and knockout-stage markets.
