Titan Battle: Messi overtakes Mbappé in the race for the 2026 World Cup Golden Boot according to Polymarket and Kalshi
Prediction markets, which have become one of the most prominent indicators of public expectations in the crypto space, have recorded a shift in the leader for the 2026 World Cup Golden Boot race. After Lionel Messi's brace against Austria, his chances of winning the tournament's top scorer award on the Polymarket platform soared to 34%, while Kylian Mbappé stands at 33%.
On Monday, June 22, both forwards scored a brace each. Messi secured Argentina's 2-0 victory over Austria, while Mbappé netted two goals in France's 3-0 win against Iraq. Thus, the Argentine now has five goals in the tournament, while the Frenchman has four.
Balance of Power in the Goalscorer Race
It is important to note that only goals scored in the current World Cup count towards the Golden Boot. Messi, with five goals, has emerged as the sole leader: a hat-trick in the opening match against Algeria and a brace against Austria put him ahead. Mbappé follows with four goals — two each against Senegal and Iraq.
The goals on June 22 made World Cup history. Messi became the tournament's all-time top scorer with 18 goals, surpassing German Miroslav Klose. Mbappé, that same night, equaled Klose's career goals, taking second place in the overall list.
Englishman Harry Kane and Norwegian Erling Haaland scored fewer goals after the first rounds, and their chances for the award have diminished. The Golden Boot race has essentially come down to a duel between Messi and Mbappé — two players who previously played together for Paris Saint-Germain.
What the Bets on Polymarket and Kalshi Show
On Polymarket, with a total betting volume of about $27.79 million, the breakdown for the leaders is as follows: Messi — 34%, Mbappé — 33%, Kane — 15%, Haaland — 10%. After the last round, Messi's odds have noticeably risen, while Kane's and Haaland's chances have declined.
On the Kalshi platform, with a turnover of about $8.21 million, the picture is somewhat different: Messi and Mbappé are tied — both at 36%, while Kane holds third place with 12%. The percentage difference between the platforms reflects different participant pools and liquidity.
On both platforms, the race for the award has come down to a showdown between the two forwards. As the playoffs approach, odds will shift sharply after each match, and the decisive factor will be how far Argentina and France advance.
Analyst's comment: Prediction markets like Polymarket and Kalshi are becoming increasingly accurate indicators of crowd sentiment. The current split — 34% vs. 33% — is not just numbers, but a reflection of the community's belief that Messi is capable of a final career crescendo. However, Mbappé should not be discounted: his physical form and motivation could turn the race at any moment. Keep an eye on the odds — they will reveal who the true favorite is.
