Prediction Markets Chase World Cup Betting Boom as Volumes Race Toward Record Territory

With the opening match still days away, prediction markets have already accumulated nearly $2bn in wagers on who will lift the World Cup trophy, a level of activity that would have seemed improbable only a few years ago.

The surge reflects both the growing influence of prediction-market platforms and the unprecedented scale of this year’s tournament. The expanded World Cup, which begins in Mexico on Thursday, will feature 48 teams and 104 matches, creating the largest football competition ever staged and, potentially, the most heavily wagered sporting event in history.

Polymarket alone has attracted more than $1.8bn in trading volume on its outright winner market. Kalshi, its US-focused rival, has generated roughly $120mn in betting activity on the same outcome. Combined, the two platforms are approaching $2bn in volume more than five weeks before the final is played.

The figures underline how rapidly prediction markets have moved from a niche financial curiosity into a significant force within global gambling. Once primarily associated with elections and economic forecasts, these platforms are increasingly positioning themselves as alternatives to traditional bookmakers, offering users the ability to trade contracts linked to sporting outcomes rather than place conventional fixed-odds bets.

For operators, the 2026 World Cup presents an opportunity unlike any previous tournament.

Analysts at Macquarie estimate that total betting turnover linked to the World Cup could exceed $50bn across all gambling channels this year, representing a 43 per cent increase compared with the tournament held in Qatar in 2022. Industry executives have described the competition as the largest betting opportunity ever created, a claim driven not only by football’s global popularity but also by the expanded format’s additional 40 matches.

More matches mean more opportunities to wager. Every group-stage fixture creates dozens of possible markets, from final results and goals scored to increasingly specific predictions surrounding individual players and in-game events.

Prediction-market operators have spent recent months preparing for the influx of attention.

Polymarket has pursued partnerships with sports media companies, including OneFootball, which plans to integrate the platform’s odds directly into coverage and match streams during the tournament. The strategy reflects a broader push to place prediction markets alongside traditional sports content rather than treating them as a separate product.

Kalshi has taken a more consumer-facing approach. The company launched its World Cup campaign with advertising featuring football manager José Mourinho and has introduced promotions ranging from giveaways to tickets for the final in New York. It also intends to display live odds updates on digital billboards across the United States as the tournament unfolds.

A Market Driven by Incentives as Much as Predictions

Yet a closer examination of the trading activity reveals that prediction markets do not always function in the way casual observers might expect.

The most heavily traded national team on Polymarket is not among the tournament favourites. It is Uzbekistan.

That statistic initially appears baffling. Uzbekistan’s chances of winning the World Cup are priced at approximately 0.01 per cent, making the country one of the longest shots in the field. Despite those odds, trading volume connected to an Uzbek victory has exceeded $58mn.

The explanation appears to have less to do with footballing confidence and more to do with the mechanics of the platform itself.

Polymarket rewards users who provide liquidity to its markets, encouraging traders to buy and sell positions even when they have little conviction about the underlying outcome. Trading records indicate that many participants who contributed to the large Uzbek volume have already closed their positions, suggesting the activity was driven primarily by reward incentives rather than genuine expectations of a historic championship run.

The phenomenon highlights one of the unique characteristics of prediction markets. Unlike traditional sportsbooks, where wagers are generally held until settlement, prediction-market participants often behave more like traders, opening and closing positions in response to price movements, incentives and market dynamics.

As volumes continue to grow, regulators and law-enforcement agencies have increasingly focused their attention on the sector.

Polymarket has already faced scrutiny over a range of markets extending beyond sports. Critics have questioned the ethics of allowing users to speculate on geopolitical conflicts and sensitive real-world events. Authorities have also investigated allegations that some traders attempted to influence the outcomes of markets directly.

One of the most unusual cases emerged in April, when a bettor was suspected of interfering with temperature measurement equipment at Paris-Charles de Gaulle Airport in an effort to affect the outcome of a weather-related market. Separately, US prosecutors are pursuing multiple cases involving alleged insider trading connected to contracts offered on the platform.

The controversies have done little to slow growth.

Instead, operators appear increasingly confident that demand for prediction markets will continue expanding, particularly around major sporting events. In recent weeks, companies regulated by the US Commodity Futures Trading Commission have used the agency’s self-certification process to introduce a wider range of football-related contracts. These include markets tied to team scoring totals, individual player performances and goals scored within specific time windows.

The result is a rapidly expanding menu of wagers that increasingly resembles the offerings traditionally associated with major sportsbooks.

Not every company, however, is benefiting from the surge in interest.

ADI Predict Street, the Abu Dhabi-based platform selected by Fifa in April as the organisation’s official World Cup prediction-market partner, has so far failed to attract meaningful trading activity. On the eve of the tournament, total volume across all of its World Cup-related markets remained below $100,000.

That contrast illustrates how concentrated the industry has become. While newer and smaller operators attempt to gain a foothold, most of the money continues to flow toward a handful of established platforms that have already built large communities of active traders.

For now, attention remains fixed on the weeks ahead. With more than a month of football still to come and billions already committed, prediction-market operators are heading into the tournament expecting record-breaking activity. Whether that enthusiasm translates into sustainable growth after the final whistle is another question. But before a ball has been kicked, the World Cup has already become one of the biggest tests yet for an industry determined to turn global sporting events into tradable financial markets.
