France’s 2-0 defeat against Spain on July 14, 2026, relieved the accounts of American bookmakers by absorbing their last major liability. Meanwhile, prediction platforms were raking in record volume, without needing the right prediction to win. Has the World Cup definitively validated the future of predictive markets compared to traditional betting?
In brief
- Spain eliminated France 2-0 in the semi-final on July 14, 2026, removing the bookmakers’ strongest exposure on the winner.
- Polymarket accumulated $4.28 billion in volume in its winner’s market, and Kalshi more than $1.22 billion.
- Kalshi, Polymarket and Polymarket US generated $44.8 billion in volume in June 2026, up 75% from May.
Bookmakers were avoiding France defeat as their worst-case scenario
When a bettor bets on the favorite and the favorite loses, the house pays nothing on this ticket: this is the elementary mechanics of a bookmaker, and it explains why the elimination of France came as a deliverance.
In the winner’s market, DraftKings and BetMGM told Front Office Sports that the French team represented their last and biggest liability in contention, while FanDuel said they attracted the most money of the teams still in the race before kickoff. The opening of the subject intersects with a broader phenomenon: the recent association of OpenAI with Kalshi for the World Cup, which placed predictive markets at the heart of the event.
The concentration of risk went beyond the simple encounter. BetMGM revealed that 94% of stakes in its qualifying market were counting on France qualifying for the final. Kylian Mbappé, the competition’s most popular goalscorer at DraftKings and BetMGM, saw bets on him against Spain outnumber those on any other player by a ratio of five to one.
These data, compiled by Bitcoin.com Newsemanate from operators’ statements to Front Office Sports. The striker and his team left without having scored a single goal.
The operators have not communicated the dollar amount of the liabilities wiped out by the Spanish victory, which prohibits any conversion into a verified profit. The betting spread, however, meant that losing tickets on France and failed bets on Mbappé remained in the bookmakers’ accounts, while winnings on Spain and other victorious outcomes had to be paid out.
Polymarket and Kalshi cash in on volume, not good prognosis
Prediction platforms operate on a radically different principle from that of betting houses. Their users exchange yes/no contracts with each other, and the exchanges collect fees rather than retaining each customer’s losing position.
France disappeared from the tournament, Polymarket and Kalshi therefore mainly benefited from the activity generated by the tricolor course, not from the feat of Spain. The same dollar can also change hands several times before settlement, which makes the volume of predictive markets not comparable to the stake made with a bookmaker.
The numbers give the measure of the phenomenon. Polymarket’s winner’s market generated approximately $4.28 billion in traded volume, and Kalshi’s topped $1.22 billion.
Polymarket rules specify that a team contract is immediately set to “No” as soon as it becomes impossible for the team to win the tournament, making the semi-final lost by France the trigger for settlement of its current contracts.
France had become the consensus favorite well before the semi-final. On July 5, 2026, it was trading at 35.4% implied probability on Polymarket, with over $94.5 million in team-specific volume, while Kalshi was pricing it at a near-identical 35.5%. This earlier shot shows massive trader confidence before Spain broke its streak.
World Cup propels predictive markets to new levels
The competition has already broken all industry records and transformed football into the most sustainable liquidity event in the history of predictive betting. Kalshi, Polymarket and Polymarket US accumulated $44.8 billion in trading volume in June 2026, an increase of 75% compared to May, driven by the continued influx of World Cup bettors.
The gap between the two models has never been more visible: bookmakers won because the public backed the wrong favorite, while exchanges benefited from traders continuing to buy and sell uncertainty, no matter which side they chose.
This dynamic reveals a structural divide in the betting sector. On the one hand, the traditional house bets on the imbalance of odds and captures the loss of bettors; on the other, the exchange charges for the flow and ignores the sporting result.
The 2026 World Cup undoubtedly marks the transition from predictive markets to the rank of real financial infrastructure, in the same way as regulated exchange platforms which are now aiming for record valuations.
In short, the elimination of France relieved the bookmakers’ accounts without changing anything in the trading model, which increased their volume over the course of uncertainty. The Spanish shock reminded us that the two industries do not bet on the same risk: one on the prognosis, the other on the movement. The 2026 World Cup will above all leave the predictive markets established as major players, like Kalshi which is now targeting a record valuation of 40 billion dollars.
