How do you explain Lionel Messi?
How do you explain what Messi is doing at 39? That question is already shaping the 2026 World Cup.
On Polymarket's World Cup: Golden Boot Winner, three days changed the entire shape of this race.
A Semifinal That Flipped the Market
Argentina beat England in a World Cup semifinal that will get replayed for years, and by full time, Lionel Messi had rewritten his market position along with a piece of tournament history.
The 39-year-old is now the outright favorite to win the Golden Boot for the first time in his career: and he'll chase it in a final played against the country where he built his entire professional life.
Argentina trailed for most of the night in Atlanta after Anthony Gordon put England ahead in the 54th minute. Messi didn't need to score to change the game. In the final minutes, he set up Enzo Fernández's equalizer with a quick corner, then delivered the cross that Lautaro Martínez headed home in stoppage time for a 2-1 win.
Harry Kane, England's captain, summed up what happened afterward in three words: "The greatest players only need one moment."
The result sent Argentina to a second straight World Cup final. It also gave Messi two assists to go with his eight goals, breaking his tie with Kylian Mbappé on the number that decides the Golden Boot when the goal count doesn't. Messi now leads 4 assists to 3.
Messi's Golden Boot Odds
Lionel Messi is just as impossible to explain as the legends who came before him. At 38, in his sixth World Cup, he rewrote the script again.
A hat-trick, his first in the World Cup, sent Argentina past Algeria 3-0, and the tears that fell after his opening goal said more than any post-match interview could. Messi later brushed off questions about what triggered them, saying only that he'd been through difficult days and was grateful to the people who'd stood by him.
The numbers, as always, did their own talking. As Messi’s third shot found the net, his Polymarket Golden Ball odds exploded, instantly narrowing the gap with Mbappé.
Now, on Polymarket, Messi has gone from second choice to outright leader, trading around 53% in the Golden Boot Winner market against Mbappé's 37%: a full reversal from where the two stood entering the semifinals, per Polymarket's own tracker.
The two are still tied at eight goals apiece, the tournament's shared high mark. What separated them is where it counts on the tiebreaker: assists.
History Is Already Written, Whatever Happens Sunday
Messi is already the first Argentine to play in three World Cup finals, and his 21 goals across six tournaments stand alone as the most in the competition's history, past Miroslav Klose's 16. He's also the first player to score in six straight World Cup knockout matches. None of that changes this weekend. What can change is whether he adds a second title and a first Golden Boot to a résumé most people stopped arguing about years ago.
The final has a shape of its own built in: Messi grew up in Rosario and left home as a young teenager to build his career in Spain: the country Argentina now has to beat to keep the trophy it's holding. Kickoff is 3 p.m. ET Sunday at MetLife Stadium in New Jersey.
Mbappé and the Others Still Have Business Left
Mbappé's title chances ended Tuesday, when Spain beat France 2-0 in the other semifinal on goals from Mikel Oyarzabal and Pedro Porro. He still has Saturday's third-place match against England to add to his tally, and a Golden Boot finish stays mathematically alive if Messi goes scoreless in the final.
Kane, on six goals, plays in that same game. Erling Haaland's run ended a round earlier, in the quarterfinals: his seven goals leave him out of the running now.
For a market that has moved on nearly every kind of headline this tournament, this is the swing that's stuck the longest. Messi is favored to win the one prize that's eluded him. Whether he does gets settled the same day Argentina and Spain settle everything else.
