Every four years, the World Cup reminds us why we fall in love with sports in the first place.

The 2026 tournament was one of firsts. For the first time, three countries — Canada, Mexico, and the United States — shared hosting duties. For the first time, the field expanded from 32 to 48 teams, giving more nations a chance to compete on the sport’s biggest stage and more federations the opportunity to showcase their depth.

That expansion brought historic debuts for Cape Verde, Jordan, Curaçao, and Uzbekistan. Their first appearances delivered some of the tournament’s most unforgettable moments.

It also felt like a farewell tour. Cristiano Ronaldo. Lionel Messi. Luka Modrić. Neymar. Son Heung-min. Guillermo Ochoa. A generation that shaped the sport for two decades took one last bow on the biggest stage, with several likely making their final World Cup appearances.

Taken together, those storylines made this World Cup feel bigger than any single match. Over the course of several weeks, the tournament gave us unforgettable goals, shocking upsets, viral celebrations, heartbreaking exits, and moments that transcended soccer altogether. Here are the moments that defined the 2026 World Cup.

Vozinha and the Blue Sharks

The best feel-good story of the World Cup has to be Cape Verde’s historic run and their goalkeeper, Vozinha (née Josimar José Évora Dias). The 40-year-old keeper and Cape Verde stalwart rocketed to international fame after a heroic performance against eventual champions Spain, keeping a clean sheet against the European giants to earn the 500,000-strong nation its first-ever points in a World Cup.

Vozinha, who was on the verge of retirement from club football, blew up on social media, amassing 29 million Instagram followers to become one of the most-followed soccer players on the platform.

The magic kept coming for the Blue Sharks. A 2-2 draw with Uruguay and a scoreless draw against Saudi Arabia secured a second-place finish in their group behind Spain, and a spot in the knockouts. There, the smallest nation ever to reach a World Cup knockout round took defending champs Argentina to the brink, including a spectacular extra-time equalizer from Sidney Lopes Cabral. It wasn’t enough — an own goal in the 111th minute gave Argentina the lead, and the win.

Even in defeat, Cape Verde and Vozinha became the darlings of the 2026 World Cup, earning a hero’s welcome when they returned home to Praia, the nation’s capital.

America’s World Cup ends in disappointment and controversy

The U.S.’s lowest moment in the tournament came wrapped in controversy. Folarin Balogun was sent off in the round of 32 against Bosnia-Herzegovina for a tackle that injured Tarik Muharemovic — a red card overturned on review, then reinstated by VAR, that should have kept him out of the quarterfinal against Belgium.

Instead, on the eve of that match, news broke that President Trump had personally called FIFA president Gianni Infantino about the suspension, and FIFA’s disciplinary committee — invoking the same conveniently vague rule it used to keep Cristiano Ronaldo eligible for his final World Cup — cleared Balogun to play.

FIFA denied any connection to the call, but the optics were brutal regardless: the first in-tournament suspension reversal FIFA had made since 1962. Balogun’s actual impact on the game was negligible — one good chance in the 82nd minute that Thibaut Courtois saved — and the U.S. lost 4-1, undone far more by sloppy defending than by anything happening off the pitch. But the timing made it impossible to separate the two.

A team that had looked loose and confident through the group stage and into the knockout rounds showed up tight and rattled.

Insane Third Place game ends Golden Boot race

The World Cup is known for its magnificent scorers: Pelé, Maradona, Klose. It’s rare to see one player absolutely rake in the goals in a single tournament, but 2026 delivered a real fight for the crown. Heading into the final weekend, Messi and Mbappé sat tied atop the table at eight goals each, having both already passed Miroslav Klose on the World Cup’s all-time scoring list along the way. Behind them, England’s Jude Bellingham and Harry Kane lingered at six apiece, two goals back but not out of it.

Then the third-place game happened, and it blew the race open. England beat France 6-4 in a match that had no business being that entertaining for a game “nobody wanted to play.”

Instead, it turned into an old-fashioned track meet. Mbappé found the net twice to push his tally to 10, breaking the tie with Messi outright and matching the mark he set back in 2022. Bellingham, meanwhile, kept crashing the box the way he had all tournament and picked up his seventh, cutting the gap to Mbappé to three with only the final left. With that crazy game over, and Spain’s 1-0 win over Argentina, Mbappé ended the tournament as the Golden Boot winner.

The last time this fixture featured multiple Golden Boot winners padding their totals was in 1990, and even that wasn’t a shootout like this one. Between Mbappé and Messi, both represent the first 8+ goal scorers since Gerd Müller scored 10 back in 1970.

We truly are blessed.

International fans experience American baseball

One of the best things about the World Cup is when international fans and players come to town and immerse themselves in local culture. The best subplot from this year’s World Cup was undoubtedly taking place at the ballpark.

With days off between fixtures, traveling World Cup fans started showing up in force at MLB games, and stadiums across the country turned into unlikely satellite fan zones. It kicked off on June 14 at Fenway, when Scottish fans fresh off a win over Haiti marched from downtown Boston straight into a Red Sox game — timed, by pure coincidence, with the ballpark’s own Scottish Heritage Night.

Two days later, the Tartan Army (the nickname for the Scottish supporters) packed part of the upper deck at Yankee Stadium, and by June 22, roughly 8,000 of them turned up in Miami for a Marlins-Rangers game, making up nearly half the announced crowd.

Norway’s supporters did their own version of the takeover at Citi Field on June 24, filling the outfield seats in Viking helmets and getting the stadium’s mascots to join their signature rowing celebration. Even England manager Thomas Tuchel, a generally terse-looking man, threw out a ceremonial first pitch at Kauffman Stadium during the team’s stay in Kansas City. He could definitely strike out Timothée Chalamet in three pitches.

U.S. visa entry nightmare

For all the goodwill the tournament generated, the road to it exposed something uglier. In the run-up to the World Cup, visa denials and delays became a recurring headache for teams, and in some cases, outright barred people from the competition entirely.

Swiss forward Breel Embolo was blocked from boarding a flight to his own team’s training camp over a year-old conviction that had already been settled back home. South Africa’s delegation nearly missed its trip to Mexico when more than 20 players and staff got stuck waiting on visas, and Iran’s team ended up sleeping in Mexico every night of the tournament after U.S. officials barred its players and staff from overnight stays, with more than a dozen federation staffers, including the federation’s own president, never cleared to travel at all.

None of this happened by accident. It was the Trump administration’s own immigration architecture doing exactly what it was built to do, and the tournament exposed it long before the opening whistle.

The policy wasn’t limited to a handful of unlucky cases: 39 countries entered the tournament under some form of U.S. travel restriction, and for 19 of them the State Department had stopped issuing visas altogether, a list that happened to include four World Cup nations (Iran, Haiti, Côte d’Ivoire, and Senegal).

Somali referee Omar Artan, freshly named his continent’s top official and set to become the first Somali to work a World Cup match, was detained for eleven hours at Miami International Airport and sent back to Istanbul over alleged “associations with suspected members of terror organizations” that CBP officials declined to specify.

To be fair, Canada has also been just as strict, with Ghanaian fans getting an 11 percent approval rate for visas to the country. Most notably, Ghanaian player Thomas Partey had his visa and subsequent appeal denied and missed Ghana’s World Cup opener due to ongoing criminal proceedings in the UK. Partey, however, was allowed to play in the team’s other group-stage matches in the US.

Through all of this, FIFA, the one body with standing to push back, chose instead to call it a host country’s prerogative.

The world falls in love with Erling Haaland

The most terrifying striker in the world seems to be a completely normal guy. It’s something only Erling Haaland seems to be able to do, with the ruthlessly efficient Norwegian striker netting himself into the Golden Boot conversation alongside Messi and Mbappé.

Off the field, though, the man nicknamed “The Terminator” is a glorified Snapchat shitposter.

On his personal Snapchat, you can find selfies with Shrek, face filters, and a bit where he wanders around Manhattan in a cap pretending nobody recognizes him. Despite being two years younger than fellow Gen Z superstar Mbappé, the Manchester City striker doesn’t seem to carry the same weight of expectations as his world soccer compatriots. This man is doing photoshoots with cowboy hats and wearing shirts that say “y’all can kiss my Dallas.”

It’s probably why the world can’t get enough of him.

Estadio Azteca

The Estadio Azteca, the home of Mexican soccer, delivered one of the most breathtaking scenes in this World Cup.

The stadium is a historic site not just in Mexico but also in World Cup history. It also made for some great memes. Mexico hosted the World Cup for the third time and, for the first time ever, won all three group-stage games. The vibes coming off El Tri and its fans were at an all-time high — probably the only thing higher than the altitude at Estadio Azteca, which became a running joke all tournament long.

While the rest of the world was watching the World Cup on Sunday evening, mathematician Levent Alpöge casually announced on X that he had used Anthropic’s Fable 5 to disprove the Jacobian conjecture.

This Tweet is currently unavailable. It might be loading or has been removed.

The Jacobian conjecture is a long-standing open problem in algebraic geometry that’s bedeviled highly accomplished mathematicians for almost 90 years. It was included in “Smale’s problems,” a list of unresolved math problems put forward by mathematician Stephen Smale in 1998.

But that proved no obstacle for Fable 5, Anthropic’s latest frontier AI model. (You may remember Fable 5 as the public version of Claude Mythos Preview, the AI model that Anthropic says has such advanced cybersecurity capabilities that it was too dangerous for public release.)

Alpöge is part of Harvard’s Society of Fellows, and his Linkedin profile notes an affiliation with Anthropic. We’ve reached out to Anthropic with questions about Alpöge’s work.

Meanwhile, for those of us who don’t understand polynomial functions from n-dimensional space, the question is: Does this represent a major breakthrough in artificial intelligence, or mathematics, or neither?

“This did not cause me to update my priors about what AI can and can’t do,” professor and mathematician Andrew Blumberg told Mashable. “This is exactly the kind of thing I would expect AI to be able to do. If there was a counterexample that was concise and easy to state that people haven’t found because it’s a pain to search through all this stuff, AI will find it.”

Blumberg, who has a joint appointment in mathematics and computer science at Columbia University, is involved in the First Proof project, an effort to test the capabilities of frontier large language models in solving research-level mathematics. So, it’s safe to say he understands mathematics and AI better than most of us.

‘You want to learn something from the answer’

Providing a counterexample to the Jacobian conjecture is still a significant achievement for AI in mathematics, Blumberg notes. But he also says there’s a big difference between providing a positive proof for a major math problem and providing a single counterexample that disproves it. Here’s the metaphor Blumberg used to explain.

“Suppose that Moses came down from the mountain with tablets, and on the tablet was written, ‘Cancer can be cured.’ Would you care? You don’t just want the answer to the question. You want to learn something from the answer. And the reason Smale thought this problem was important is because he thought that if we solved it, we would understand more things about the about the way nature is structured.”

In other words, Blumberg says, “this counterexample tells us essentially nothing. It’s just, you know, there are a lot of polynomials, and it’s hard for people to check them all, but it’s not hard for machines.”

The Jacobian conjecture isn’t the only math problem AI has tackled in recent months. OpenAI announced in May an “internal model” had disproved the Erdős unit distance conjecture, a central conjecture in discrete geometry.

However, in that case, the result was more productive, Blumberg says. That’s because OpenAI didn’t just provide a counterexample — but a disproof of the problem itself.

“The disproof there already has led to interesting things because experts in the area unpacked what was going on in the disproof and then used it to do other things,” Blumberg says.

And that’s not necessarily the case with the Jacobian conjecture counterexample, he adds — while conceding he’s not expert enough to see if there’s something special about the structure of the counterexample that we can learn from. “But it’s not in and of itself interesting.”
