Will Kylian Mbappe be the top goalscorer at the 2026 FIFA World Cup?

Across sportsbooks, Mbappé is the clear favorite to win the Golden Boot, typically around +600 (6/1), which is roughly a 14–17% implied chance to finish as top scorer in a 48‑team World Cup. Listing boards are basically “Mbappé first, then Kane, then Haaland/Messi/Yamal etc.,” and handle data shows he’s also taking the biggest share of bets and money in that market. Prediction markets agree he’s the front‑runner, but they’re a bit more conservative. Top‑scorer markets have Mbappé as the leading outcome with something like a 18–21% probability, ahead of Kane and Haaland. So when you look at this specific Polymarket line and see a whale on “No,” they’re not saying Mbappé is overrated as a player; they’re just leaning into the math of Golden Boots: even the favorite still loses 4 times out of 5 in expectation, and injury, rotation, or France stalling out a round early all pay that “No” with no need for a crazy upset.
