Harry Kane against Lionel Messi: two captains, two of the World Cup’s top scorers, and a semi-final that is very probably Messi’s last. They meet in England vs Argentina in Atlanta on Wednesday, July 15, with the Golden Boot as the subplot: Messi near the front, Kane chasing.
Here is the twist Squawka Signal adds. The betting market makes England narrow favourites to go through; the model does not, leaning Argentina and rating them the stronger side. So Signal sits on Messi’s side of the night twice over: at or near the top of its Golden Boot board, playing for the team it fancies to reach the final. Kane and England would be the upset.
Not that Wednesday settles the Boot. Mbappe is level with Messi on 8 and in the other semi-final, and the losing captain here plays the third-place game rather than going home, so the Boot race runs on. The final is what Wednesday actually decides. Below: where the race stands, how the two compare, and what the model and the markets each make of the game.
Harry Kane vs Lionel Messi

Harry Kane vs Lionel Messi: the head-to-head numbers
Two captains, two completely different kinds of forward. Messi has scored more (8 to 6) and is also the tournament’s chief creator, with 21 chances made to Kane’s five; Kane is the penalty-box finisher, ahead on big chances converted and the only one of the two scoring with his head. Our Comparison Matrix has the full side-by-side.
The radar tells it at a glance. Messi’s shape stretches across goals, shots and, above all, chances created; Kane’s pushes out on the things a No. 9 is for, headed goals and clear-cut chances put away. One is the team’s creative engine as well as its scorer; the other is the man you want on the end of the move. In a tight semi-final, both edges matter. We break each down in our Lionel Messi and Harry Kane Golden Boot odds pieces.
What Squawka Signal makes of it
Signal has Messi at 47.5% for the Golden Boot, among the very top of its board and rated a standout value play: the model puts him well above the 34% the markets give him, on the back of 8 goals and a creative load no one else is carrying. Kane sits far back on 3.7%, fair against his own market price but a long shot for the award while the men above him keep scoring.
So the model’s interest in Kane here is not really the Boot; it is the game, and this is where Signal parts company with the market. Kalshi’s traders make England narrow favourites to go through; Signal does not, giving Argentina the edge at 53% to England’s 47% and rating them the stronger side on our World Cup 2026 winner odds. For Kane, that frames the night as an upset: beat an Argentina team the model rates higher and he takes England to the final at Messi’s expense. Both play at least once more either way, one in the final and one in the third-place game, so the Golden Boot is not settled here; but the bigger prize goes to the winner, and Signal makes that Messi’s Argentina.
The match markets: England vs Argentina
The prediction-market read starts with who goes through. Kalshi has England as narrow favourites to reach the final, with Argentina just behind. The goalscorer markets are near-level, the two captains priced within touching distance of each other to find the net. For how these prices work as probabilities, our guide to Kalshi covers it.
The semi-final markets
On the day it is close to a coin flip, the two captains priced within touching distance to score on Kalshi and at bet365 alike. Over the tournament, Messi is the runaway Golden Boot favourite, and both captains play at least one more game whatever happens here, so the Boot race runs on past this tie either way.

The other contender: Mbappe in the Spain semi-final
Whatever happens in Atlanta, the Golden Boot is not settled. Kylian Mbappe is level with Messi on 8 and faces Spain in the other semi-final, and Signal rates him overpriced against the market despite that goal tally. Here is the full board, so you can see where Kane, Messi and Mbappe sit against each other and the field.
