Player propositions were included in 65% of Bet Builders, up from 25% in 2022. Meanwhile, player shots on target became Kambi’s second-largest pre-match betting offer by turnover, while other popular selections included a player to score or assist.

AI also helped Kambi reduce the delay between a customer selecting an in-play bet and being able to place it. Its dynamic live delay technology enables it to set bespoke live delay on an individual bet level, optimising the UX and alleviating friction. Across the Premier League and World Cup, Kambi reduced live betting delay by more than 40% between August 2025 and July 2026.
