There are moments in sport that transcend the result on the scoreboard, and June 22, 2026, belongs firmly in that category.
With two goals in Argentina’s 2-0 victory over Austria at AT&T Stadium in Arlington, Texas, Lionel Messi didn’t just help the defending world champions punch their ticket to the Round of 32. He became the greatest goalscorer in FIFA World Cup history, men’s or women’s.
Messi makes history
In the 38th minute, Messi scored his 17th World Cup goal, surpassing the previous record of 16 set by Germany’s Miroslav Klose, a mark that had stood since the 2014 World Cup in Brazil. Then, almost as an afterthought, Messi added an 18th in stoppage time, leapfrogging Brazilian legend Marta, who holds the women’s record with 17.
At 38 years and 363 days old, in his sixth and almost certainly final World Cup, Messi has done something no footballer, male or female, has ever accomplished. He has now scored in six consecutive World Cups for Argentina, a feat matched by only two other players in history.
The reception from the 70,000-strong crowd in Arlington was thunderous, a standing ovation for a man who has long since graduated from football legend to living monument.
Group J: Mission accomplished
Argentina’s path through Group J has been a masterclass in defending champion pedigree. The tournament opened on June 16 with a 3-0 demolition of Algeria at Arrowhead Stadium in Kansas City, a match in which Messi delivered his first-ever hat-trick at a World Cup, equaling Klose’s record in the process.
That result, combined with Austria’s 3-1 win over Jordan, set the tone for a group that was effectively over before it truly began. The win over Austria sealed Argentina’s place in the knockout round with a game to spare.
With their final group match against Jordan on June 27 remaining, Argentina need only a draw to lock up first place in Group J. As Group J winners, they are projected to play their Round of 32 match on July 3 at Hard Rock Stadium in Miami, facing the runner-up from Group H, which includes Spain, Uruguay, Cape Verde, and Saudi Arabia.
Argentina’s World Cup markets
The prediction markets have taken note of Argentina’s imperious form, and the numbers tell a compelling story.
On both Kalshi and Polymarket, the defending champions are priced between 14% and 15% to win the tournament outright, with a combined trading volume across the two platforms exceeding $87 million, a testament to the depth of public interest in their campaign.
The round-by-round progression markets paint a picture of a team that the market believes will go very deep into this tournament. The quarterfinals are seen as better-than-even money, with their chances of reaching the quarters sitting around 67-70%, and making the finals is priced near 29-31%. Those prices make them one of the co-favorites to reach the World Cup finals alongside France and Spain.
| Stage | Kalsh | Polymarket | Combined Volume |
|---|---|---|---|
| Wins the 2026 World Cup | 14% | 15% | $87.1M |
| Reaches Round of 16 | 85% | 83% | $181K |
| Reaches Quarterfinals | 70% | 67% | $297K |
| Reaches Semifinals | 50% | 46% | $248K |
| Reaches Final | 31% | 29% | $236K |
Lionel Messi’s individual markets
Away from the team picture, Messi’s individual prediction markets are equally riveting. The most lopsided line on the board is his head-to-head goal comparison with Cristiano Ronaldo, where both Kalshi and Polymarket price Messi as the overwhelming favorite, with Polymarket sitting at 90% and Kalshi at 93%.
The Golden Ball market, awarded to the tournament’s best player, has Messi at 26% on both Kalshi and Polymarket. And perhaps most eyebrow-raising for the historically-minded: despite being the tournament’s all-time leading scorer, Messi has never won the Golden Boot.
The market for him to score 6+ goals in this World Cup is currently 92-98%, with five goals already in the books through just two matches. That outcome looks imminent.
| Market | Kalshi | Polymarket |
|---|---|---|
| Messi beats Ronaldo in goal contributions | 93% | 90% |
| Messi gets 6+ goals in the 2026 World Cup | 98% | 92% |
| Messi wins Golden Ball | 26% | 26% |
| Messi wins Ballon d’Or | 18% | 12% |
The Golden Boot race: Messi vs. Mbappe
If Argentina’s World Cup run provides one enduring storyline, the Golden Boot duel between Messi and Kylian Mbappe provides the other. After two group-stage matches, Messi leads the tournament with five goals while Mbappe is right behind with four, and both men scored on June 22 alone.
The rivalry is nothing new. In Qatar in 2022, Mbappe claimed the Golden Boot with eight goals while Messi, despite winning the Golden Ball and the title itself, was pipped in the scoring charts.
Now, with both players in blistering form and the prediction markets in virtual lockstep, the race feels personal. Mbappe himself has tried to play it cool, telling reporters, “It’s not something I’m concentrating on at the moment. Leo always finds the net. If I start monitoring his performance, I might feel pressured to do more”.
That kind of deference from the world’s second-best player speaks volumes. On Kalshi, Messi holds a marginal edge at 38% versus Mbappe’s 32%, while Polymarket has Messi at 34% versus Mbappe at 30.5%. With $1.5M on Messi and $1.8M in combined volume across Mbappe markets, the trading public is clearly transfixed.
| Player | Kalshi | Polymarket | Volume |
|---|---|---|---|
| Lionel Messi | 38% | 34.2% | $1.5M |
| Kylian Mbappe | 32% | 30.5% | $1.8M |
Strong prediction market outlook for Argentina
Argentina’s final group game against Jordan on June 27 in at AT&T Stadium is little more than a formality, the defending champions need only a draw to finish first in Group J. Their reward, should they top the group as expected, is a Round of 32 date on July 3 at Hard Rock Stadium in Miami against the runner-up from Group H.
Current projections have Uruguay or Cape Verde as the opponent. Saudi Arabia, the side that famously beat Argentina in 2022, is also in the mix.
The broader market picture tells you everything you need to know about where Argentina stands in this competition. Nearly even odds at the semifinal stage, a near-30% chance of reaching the final, and a 14.5% chance of winning it all place them firmly among the two or three most likely champions.
With Messi in the form of his life, scoring all five of his country’s goals so far, rewriting the record books, and playing with a hunger that belies his nearly-39 years, the prediction markets are simply reflecting what the eyes are telling you. The defending champions aren’t just advancing. They are hunting history.
