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.
The result for customers was more choice, shorter suspension periods and faster bet acceptance. For operators, those improvements can support both customer retention and profitability.
While simulations and validation exercises had helped Kambi prepare for the traffic and operational demands of the 2026 World Cup, testing could not establish how performance would compare with the wider market once the football began.
