France Tops World Cup Prediction Markets as Knockout Stage Gets Underway

As the 2026 FIFA World Cup enters its knockout phase, prediction market data reveals a clear consensus among bettors: France is the most likely nation to lift the trophy. Both Polymarket and Kalshi — representing decentralized and regulated markets respectively — place France at the top of their winner odds, with Argentina nipping at their heels.

On Polymarket, France commands a 23% implied probability of winning the tournament, while Argentina sits just one percentage point behind at 22%. Spain follows in third place with 11%, England holds fourth at 10%, and Brazil rounds out the top five with a 6% chance. Over on Kalshi, the US-regulated exchange, the ranking is identical at the top: France leads at 20%, with Argentina at 16%.

Combined, France and Argentina absorb over 45% of all winning predictions on Polymarket alone — a concentration that effectively frames the competition as a two-team contest in the eyes of the betting public. France enters the knockout rounds as the statistical front-runner, while Argentina, the reigning world champion, continues to attract confident backing from those who believe Lionel Messi and his squad can defend the title.

This pattern is consistent with earlier observations from analysts tracking money flow throughout the group stage, where capital was noted to cluster around a handful of elite national teams. Kalshi also made headlines prior to the tournament after partnering with ADI and PredictStreet to expand regulated soccer betting options for users in the United States.

Beyond the wagering landscape, the 2026 edition has already made history in terms of fan attendance. FIFA has officially confirmed that cumulative stadium attendance has exceeded 3.6 million spectators — a record for any World Cup in history. The milestone was made possible in part by the tournament's expanded three-nation hosting arrangement across the United States, Canada, and Mexico, which allowed for a significantly larger number of venues.

Fan token markets have also responded to the tournament's energy. Digital tokens linked to national teams surged at the conclusion of the group stage, driven by heightened supporter engagement. Prediction platforms like Polymarket and Kalshi have simultaneously benefited from increased mainstream visibility, using the World Cup as a vehicle for broader brand recognition.

Looking further ahead, FIFA is reportedly weighing another structural expansion. According to Sports Business Journal, the governing body is internally discussing a move to a 64-team format by 2038. The current 48-team setup, debuted at this very tournament, already tested the logistical capabilities of its host nations considerably.

For cryptocurrency market participants, the World Cup cycle carries an additional layer of intrigue. Historical analysis has shown that Bitcoin has tended to post above-average returns during FIFA World Cup years, a pattern tied to the sport's four-year calendar. Whether that correlation holds true in 2026 remains to be seen as the knockout rounds progress and the field narrows toward a champion.
