World Cup kicks off: Host nation Mexico secures first victory, prediction markets set to face a "watershed moment"

```

The 2026 USA-Canada-Mexico World Cup has officially kicked off. This globally watched sporting event not only ignited fan enthusiasm, but also stirred up waves in the prediction markets.

On Thursday, host Mexico defeated South Africa 2–0 at Azteca Stadium, marking the opening of this year’s tournament. Investment firm Bernstein released a report stating that this World Cup is expected to become the largest single catalyst in the history of online sports and prediction markets, with relevant transaction volumes possibly reaching $10 billion.

Bernstein characterizes this World Cup as a “potential watershed moment” for prediction markets, believing the tournament will accelerate growth momentum for platforms like Kalshi and Polymarket, as well as provide an important expansion window for prediction market businesses of mainstream financial platforms such as Robinhood and Coinbase.

Mexico Wins Opening Match, Three Red Cards Add Drama

The opening match of this World Cup was held at Azteca Stadium in Mexico City. Mexico secured an easy 2–0 victory over South Africa thanks to Julian Quinones’ early goal and Raul Jimenez’s header in the second half.

The match was far more dramatic than the scoreline suggests. South African player Sphephelo Sithole received a red card for a tackle early in the second half, followed by teammate Themba Zwane who was also sent off after VAR intervention. Mexico’s Cesar Montes was expelled before the final whistle for preventing a scoring opportunity. The three red cards made the opening match tense and somewhat overshadowed what should have been a festive atmosphere.

Despite this, the enthusiasm of the home fans was undiminished. Mexico’s coach Javier Aguirre told reporters after the match: “This game could have ended 4–0. We didn’t play well, but the fans are happy. This is the beginning of the World Cup—we’ve overcome our nerves, got the three points, and now we need to focus on the next match.”

Historic “Firsts”: Largest World Cup Officially Begins

This tournament set several historical records. It is the first World Cup to expand to 48 teams, the first to be jointly hosted by three countries, and Azteca Stadium is hosting the opening match for the third time—a record.

This edition has a total of 104 matches, about 60% more predictable matches than previous tournaments. Mexico has broken a 96-year World Cup curse, ending a streak of seven opening matches without a win, achieving its own “first.”

Mexico will face South Korea next on June 18 in Guadalajara, while South Africa will play the Czech Republic in Atlanta the same day.

$10 Billion Bets: Prediction Markets Face Key Catalyst

Off the pitch, Wall Street is closely watching another set of numbers. Bernstein analysts predict the World Cup will drive over $3 billion in incremental volume, and boost broader consumer transactions on sports prediction platforms up to $10 billion.

Bernstein notes that data from relevant platforms already show an obvious upward trend ahead of the tournament opening. DraftKings disclosed this week that consumer transaction volume in May grew 24% month-on-month to $1.3 billion, with total transaction volume growing 34% to $3.1 billion, continuing nearly three months of rapid growth.

“We have always believed that prediction markets represent a new way of monetizing sports engagement, rather than a disruptive threat to traditional platforms,” Bernstein analysts wrote. “Kalshi and Polymarket have rapidly expanded in California, Texas, Georgia, and Florida. We believe the World Cup will create accelerated customer acquisition opportunities for other platforms, pushing the overall market toward $1 trillion in transactions by 2030.”

Robinhood and Coinbase Leverage World Cup for Prediction Markets

Mainstream financial and crypto platforms are taking this World Cup as a key opportunity to expand their prediction market business.

According to Decrypt, Robinhood launched World Cup event contracts developed by Rothera—an independent CFTC-licensed prediction market exchange, and Robinhood invested in it together with Susquehanna International Group.

Coinbase, meanwhile, is offering World Cup contracts through its partnership with Kalshi. Coinbase previously revealed that after its prediction market product launched in early 2026, annualized revenue exceeded $100 million in just two months.

User data from prediction market platform Myriad shows that Spain is currently seen as the favorite to win, with an 18% chance, followed closely by France at 17%.
