Altenar, a leading sportsbook provider, has released its latest industry report, World Cup 2026: How Bettors Really Bet, analyzing betting activity across all 104 matches of soccer’s biggest global tournament.
Rather than simply looking at which matches attracted the most bets, the report explores what bettors were actually betting on, how their behavior changed as the tournament progressed, and where the biggest commercial opportunities emerged for operators.
One of the standout findings is the continued rise of Bet Builders, which accounted for 39.6% of all singles bets during the World Cup—almost double the 20.28% recorded at UEFA Euro 2024.
The report takes a closer look at which matchups saw the strongest Bet Builder adoption and what this tells us about the growing role of multi-selection betting in soccer.
The data also reveals a significant increase in stake size as the tournament reached its decisive stages. Average stakes rose from around €3–5 during the group stage to approximately €10–13 in the quarterfinals, semifinals, and final.
The report examines the influence of fame, form, and fan sentiment on betting behavior. In player markets, meanwhile, the biggest names dominated betting interest, with Player Special market turnover reaching approximately 400% of its Euro 2024 level.
These are just some of the findings explored in the document. The full report goes deeper into:
-
stake behavior
-
Bet Builder adoption
-
singles and multiples bets
-
market preferences
-
match-level turnover and bet counts
-

-

-
the relationship between bettor attitudes and tournament outcomes.
This data gives us a clear view of how betting behavior evolved throughout the tournament: from the growing popularity of Bet Builders to the significant increase in stakes around the decisive matchups. This is where the flexibility and depth of Altenar’s sportsbook really come into play.
The ability to support a broad range of markets, respond to changing betting trends, and deliver engaging experiences across different stages of a major tournament gives our partners the tools to capture these opportunities as they emerge.
