Goldman Sachs has entered the World Cup prediction business again, and this time they're backing Spain. According to a report led by chief economist Jan Hatzius, Spain holds a 26% chance of lifting the trophy, with France at 19% and Argentina at 14%. Wall Street has spoken. Football, however, doesn't care.
The model pulling these numbers draws on nearly 20,000 matches played since 1978. It factors in historical performance, scoring talent, team momentum, and geography. There's even a specific warning about Argentina — Goldman flagged what they call "the winner's slump," suggesting back-to-back champions are historically prone to underperforming. Make of that what you will when pricing up La Albiceleste's outright odds.
Goldman missed badly in 2018
Worth knowing before you treat this as gospel: Goldman ran one million simulations ahead of the 2018 World Cup and projected a Brazil vs. Germany final. Brazil went out in the quarterfinals. The actual final was France vs. Croatia, and France won. Goldman had France as their second pick, so they'll claim partial credit — but the headline miss was significant.
Their own economists admit the model is "limited" and acknowledge soccer's "inherent unpredictability." It doesn't account for player injuries, managerial experience, or squad depth in any meaningful way. Jacek Dmochowski, an engineering professor at The City College of New York, put it plainly: this is "a fun exercise" rather than a serious forecasting tool. The model works off a "tiny sliver" of the information that's already priced into betting and prediction markets.
That last point matters. Platforms like Polymarket and Bet365 are currently placing Spain below the 20% mark — lower than Goldman's figure — with France in a similar range. Those markets absorb everything: injury news, squad form, managerial changes, public sentiment. A bank's quantitative model, however sophisticated, is playing catch-up.
What this actually means for the 2026 outright market
Spain's form under Luis de la Fuente has been sharp — Nations League winners, a young squad built around Lamine Yamal and Nico Williams, and genuine depth across the pitch. The 26% Goldman figure isn't outlandish. France, perpetually overstocked with talent regardless of internal drama, at 19% also tracks with where the market sits.
Goldman also broke down Round of 16 probabilities for the three host nations: Mexico leads at 68%, Canada sits at 50%, and the United States trails at 39%. The US number will sting for home fans, but it reflects a squad still searching for a tournament identity.
- Spain: 26% chance to win (Goldman) / below 20% (Polymarket, Bet365)
- France: 19% chance to win
- Argentina: 14% chance to win
- USA Round of 16 probability: 39%
- Mexico Round of 16 probability: 68%
- Canada Round of 16 probability: 50%
Dmochowski's closing thought is the most honest thing in the whole report: "It's impossible to know who was right." That's football. Goldman Sachs knows it. The markets know it. Anyone pricing a World Cup winner 12 months out is operating in educated guesswork — just with better spreadsheets.
