Kambi World Cup Report 2026: Bet Builder doubles to 35% of tickets as player props take over the sportsbook

Kambi’s World Cup Report 2026 shows Bet Builder doubled to 35% of all tickets on its network, live Bet Builder jumped from 3% to 22% of in-play bets, and 65% of builders now carry at least one player prop.

Key takeaways:

• More than 100 million bets and over €1 billion in Turnkey Sportsbook turnover passed through Kambi’s World Cup book, with operator trading margin at 18% and 100% platform uptime throughout the tournament.
• The Spain–Argentina final alone generated more than one million unique bet combinations — the most complex single-match book Kambi has ever traded.
• Bet Builder doubled its share of tickets to 35% of all bets (17% in 2022). Users of the product placed 3.3 times as many bets as non-users, and 72% of builders now carry three or more selections.
• Live Bet Builder rose from 3% to 22% of in-play tickets. Live builder users placed 2.4 times as many live bets and covered 2.2 times as many live matches.
• Player props sat inside 65% of Bet Builders, up from 25% in 2022. Shots on target was the leading pre-match prop (48% of those tickets) and the leading live prop (42%).
• Nearly one in four Kambi-network bettors were first-time customers during the tournament and contributed 13% of turnover; 27% of newcomers used a bonus on their first ticket, while 17% of newcomers had already bet a non-World Cup event before the final.

Special report.- Bettors on Kambi’s global network placed more than 100 million wagers across the 104 matches of the 2026 FIFA World Cup, generating over €1 billion in Turnkey Sportsbook turnover as Spain beat defending champions Argentina 1-0 after extra time in the 19 July final at MetLife Stadium. Kambi’s World Cup Report 2026, compiled from more than 60 Turnkey partners, shows why the tournament mattered commercially: Bet Builder doubled its share of tickets to 35%, live Bet Builder rose from 3% to 22% of in-play bets, and 65% of Bet Builders now carry at least one player prop, up from 25% in 2022. Nearly one in four customers placed their first wager on the Kambi network during the competition, and those first-time tickets accounted for 13% of tournament turnover.

The report is the supplier’s fullest public readout of how demand actually behaved once the expanded 48-team, 39-day tournament was over. It sits alongside Kambi’s Q2 results, which put operator trading margin for the full World Cup at 18%, average turnover per match about 20% higher than in 2022, and platform uptime at 100%. Partners’ GGR on the event was described on the earnings call as three times the 2022 level.

This instalment of Focus Gaming News’ World Cup coverage uses that dataset to answer a narrower question than who lifted the trophy: what did customers actually bet, and which products turned a five-week spike into something operators can keep?

How large was World Cup betting on the Kambi network?

More than 100 million bets flowed through Kambi’s Turnkey Sportsbook alone. That figure excludes the additional volume on Odds Feed+. The final itself produced more than one million unique combinations. Semi-finals had already cleared 700,000 unique combinations per match.

Commercial context matters because the fixture list was longer, not just louder. FIFA staged 60% more matches than in 2022. Kambi still reported higher average turnover per match and a higher average stake. Americas partners generated 57% of global network turnover during the Q2 portion of the tournament, against 38% at the 2022 World Cup — a reminder that kick-off times that were awkward for Europe were a feature, not a bug, for a geographically spread book.

Acquisition was not a side-effect. Almost one in four bettors on the network were new to Kambi during the World Cup, and they contributed 13% of turnover. The matches most likely to be a customer’s first ticket were Spain–Argentina in the final, Norway–England in the quarter-finals, Brazil–Morocco and Mexico–South Africa in the group stage, and France–Sweden in the round of 32.

How much did Bet Builder grow at the 2026 World Cup?

Bet Builder accounted for 35% of all World Cup bets in 2026, against 17% in 2022. The number of Bet Builder tickets doubled. Users who touched the product placed 3.3 times as many bets as those who did not.

Combination size moved with volume. Average pre-match Bet Builder selection size rose from 2.9 to 3.5. Bets with three or more legs were 72% of Bet Builder tickets, up from 55%. The mix by number of selections:

• Two selections: 45% in 2022, 28% in 2026
• Three: 25% to 24%
• Four: 13% to 19%
• Five: 7% to 11%
• Six or more: 10% to 18%

That is a higher-margin book, provided the pricing and risk engine can stand the combinability. Mid-tournament Kambi figures put pre-match Bet Builder turnover 3.6 times higher than in 2022, which is consistent with fewer two-leg tickets and a thicker average stake.

Live Bet Builder followed the same path faster. It was 5% of Bet Builder tickets in 2022 and 14% in 2026. As a share of all live bets, it went from 3% to 22%. The report records a seven-fold increase in the number of live Bet Builder bets; earlier trading updates put live Bet Builder turnover up ten-fold. Both point in the same direction: in-play is no longer a 1X2 and totals board.

Which player props and selections dominated Bet Builders at the 2026 World Cup?

The 2022 hierarchy was still recognisable — full-time result, total goals, both teams to score, corners — but player shooting markets jumped the queue.

Top Bet Builder selections in 2026, with 2022 rank in brackets:

• Player shots on target (6)
• Full time (1)
• Total goals (2)
• Player to score (5)
• Both teams to score (3)
• Total corners (4)
• Player shots (20)
• Player to score or assist (not ranked in 2022)
• Total cards (9)
• Total corners by home team (8)

Player shots on target was also Kambi’s largest pre-match Bet Builder market by turnover during the tournament, at one point generating twice the turnover of the match-winner market. The share of pre-match turnover coming from anything other than match winner rose from 57% to 63%.

That is the structural shift the report is really documenting. The World Cup still sells winners. It now sells more of the moments around them.

Did live betting change as the tournament progressed?

Yes. Live remained the engagement engine, and the customers who used it were sticky.

Kambi’s stage-by-stage retention split shows that a large share of live bettors either stayed through every later round or at least came back for the next one. Drop-off existed — it always does once a favourite is eliminated — but the live cohort did not behave like a group-stage tourist class. Latin America posted the highest live share of bets at 23%, with Europe at 19% and both North America and the rest of the world at 20%.

The matches with the highest live share of tickets were not a simple list of the most famous names. They were matches that refused to end on 90 minutes:

• Spain vs Argentina (final): Spain controlled the contest; Emiliano Martínez made 11 saves; Ferran Torres scored in extra time
• Switzerland vs Colombia (round of 16): 0-0, Switzerland 4-3 on penalties
• Germany vs Paraguay (round of 32): extra time and penalties, Paraguay 4-3
• England vs Argentina (semi-final): England led 1-0, Argentina scored in the 85th minute and in stoppage time
• Norway vs England (quarter-final): 1-1 after 90, Jude Bellingham in extra time

In the four matches that reached penalties, live engagement outpaced elapsed time in the first period of extra time and from the spot. The commercial implication is blunt: a live book that suspends, lags or thins out its market list in extra time is abandoning the minutes when customers are most willing to bet.

The Spain–Argentina final chart makes the same point in another way. Ticket flow stayed alive through the long half-time, jumped at hydration breaks, and spiked again before extra time and in the extra-time interval. Single bets still dominated the stack, but two-, three- and four-leg tickets rode the same peaks.

Live Bet Builder users themselves were a distinct segment:

• They averaged three selections per live builder
• They placed 2.4 times as many live bets
• They wagered on 2.2 times as many live games
• They were 46% of live bettors, 22% of live bets and 12% of live turnover

High user share, lower turnover share is the recreational fingerprint: more tickets, smaller average stake, more sessions.

Why did player props move to the centre of the book?

Because the audience was watching players, not just nations, and because those markets are now combinable.

Player-prop users placed 3.4 times more bets and wagered on 2.4 times more matches than non-users. Sixty-five per cent of Bet Builders contained at least one player prop. In 2022, that figure was 25%.

Top pre-match player props by share of player-prop tickets:

• Player shots on target — 48%
• Player to score — 18%
• Player to score or assist — 8%
• Player shots — 7%
• Player to score at least X goals — 5%

Top live player props:

• Player shots on target — 42%
• Player to score — 19%
• Player shots on target in the first two minutes — 7%
• Player shots — 6%
• Scorer of the goal at full time — 6%

Shots on target is the product story of the tournament. It is frequent enough to feel live, specific enough to feel personal, and liquid enough to sit inside a builder without killing the price. Kambi had flagged that pattern before kick-off; the full dataset confirmed it.

Turnover still clustered around a short list of names. Top players by turnover: Kylian Mbappé, Lionel Messi, Harry Kane, Lamine Yamal, Erling Haaland, Luis Díaz, Michael Olise, Jude Bellingham, Cristiano Ronaldo, Ousmane Dembélé. Group-stage snapshots had already shown how concentrated that demand can be — Haaland, Messi, Kane, Mbappé and Ronaldo each accounting for 40–60% of player-prop turnover in the matches they actually played. Auto-sub, which moves a prop onto the replacement if a player is withdrawn, is now part of how operators keep those tickets alive rather than void.

Retention followed the product. At every knockout stage, Bet Builder users and player-prop users were more likely than the average customer to bet the next round. From the group stage, overall retention into the next stage sat at 54%; Bet Builder users were at 61% and player-prop users at 64%. The gap persisted through the round of 32 (73% and 74% against 65% overall) and the quarter-finals (68% and 69% against 61%).

Which teams and matches generated the most betting turnover at World Cup 2026?

Top teams by turnover:

• Argentina
• France
• Spain
• England
• Colombia
• Brazil
• Belgium
• Germany
• Morocco
• United States

Top matches by turnover:

• Spain vs Argentina (final)
• England vs Argentina (semi-final)
• France vs Spain (semi-final)
• Switzerland vs Colombia (round of 16)
• Norway vs England (quarter-final)
• France vs Morocco (quarter-final)
• Spain vs Belgium (quarter-final)
• Argentina vs Switzerland (quarter-final)
• France vs England (third-place match)
• Mexico vs England (round of 16)

The list is not identical to the first-bet list. New customers arrived on narrative fixtures and host-adjacent ties; the heaviest turnover sat where elite teams, extra time and star forwards overlapped. Switzerland–Colombia as the fourth-highest turnover match is the tell: a round-of-16 penalty shootout can out-earn a tidy quarter-final if the live product holds.

Altenar’s separate World Cup 2026 readout, published the same week as this report cycle, pointed in the same direction from another supplier’s book: Bet Builders at 39.6% of singles, versus 20.3% at Euro 2024, and player-special turnover roughly four times the Euros level. The Kambi numbers are not an isolated house view.

How did promotions and first-time bettors behave?

New World Cup customers used a bonus on their first bet more often than in 2022: 27%, up from 21%. Across bonus types, the mix shifted.

• Any bonus: 21% in 2022, 27% in 2026
• Free bet: 12% to 16%
• Profit boost: 2% to 6%
• Odds boost: 7% to 3%
• Second chance (not offered in 2022): 2%

Free-bet demand clustered on Luis Díaz, Harry Kane, Cristiano Ronaldo, Vinícius Júnior and Mbappé. Boosts clustered on Mbappé, Kane, Vinícius, Messi and Ronaldo. Kambi also treats Auto-Sub and Early Settlement as product features rather than campaign bonuses — a distinction operators should keep when they compare “promo cost” across suppliers.

Promotions helped the front door. They do not explain why Bet Builder and prop users came back after their team was knocked out. That is a product and content problem, not a free-bet problem.

What filled the gaps when the football stopped?

Esoccer. Since Kambi rebuilt the vertical in 2023, it has become a top-five sport on the network by number of bets, behind football, horse racing and basketball.

The report’s match-day charts for the England–Argentina semi-final and the Spain–Argentina final show the same shape: activity in the pre-match window, a dip once the real game kicks off, a spike at half-time, another after the final whistle. In the final, the extended half-time made the substitute product even more visible. Esoccer is not competing with live football. It is selling the dead air around it.

The same logic applies off the pitch. During the tournament, 39% of existing World Cup bettors struck at least one non-World Cup wager. Among World Cup newcomers, the figure was already 17% before the final, with traffic leaking into Wimbledon, the NBA Finals, MLB and other football. Cross-sell is how a 39-day event becomes a 12-month customer.

What should sportsbook operators learn from World Cup 2026 betting data?

Three operational conclusions sit on top of the vanity numbers.

First, combinability is no longer a differentiator. It is table stakes, and the World Cup rewarded books that could offer player props inside both pre-match and live builders without long suspensions. Kambi’s first fully AI-traded World Cup is the infrastructure story underneath that: more than 60% of network bets in 2026 were already on offers priced and traded by AI, according to SVP Trading Simon Noy, speaking to Focus Gaming News before the tournament. The final still needed humans on the risk desk. The million combinations did not.

Second, retention is a product attribute. Bet Builder and player-prop users returned at higher rates at every stage. If an operator’s World Cup P&L is built only on match-winner margin in the group stage, it is leaving the expensive customers on the table.

Third, the calendar after 19 July is part of the event. Esoccer, tennis, basketball and domestic football are how first-time World Cup tickets become accounts. Kambi’s own network already saw 17% of newcomers betting off-tournament before the closing ceremony. That number should be a KPI, not an anecdote.

Oliver Lamb, Kambi’s SVP Trading, framed the report as a template rather than a souvenir: the growth in Bet Builder before and during matches, and the rise of shots-on-target as a default leg, are trends that will travel into club competitions. That is the test. A World Cup can inflate any metric. The question is whether the same customers still want a three-leg builder on a Saturday in November.

None of this removes the usual duties around safer gambling. A book that makes it frictionless to stack four player legs in the 118th minute is also a book that needs session tools, reality checks and affordability controls that work at the same speed as the trading stack. The report does not quantify harm. Operators still have to.
