What is Book of Gold?
One of the proposals could be voted on next week by the city council and would directly affect the city’s clubs.
The meeting brought together 40 professionals from the clubs’ legal, communications and marketing departments, as well as executives from companies in the betting sector. Club officials are concerned about the financial impact of the measures, which could impact sponsorship contracts signed with betting companies.
One of the main concerns is Bill 560/2025, which is currently making its way through the council. The proposal prohibits advertising by betting companies at events in the city of São Paulo. This applies to events organised by public or private entities, whether for-profit or non-profit.
How to play Book of Gold
“Customers seek personalised experiences, extensive player proposition bets and the ability to build highly customised wagers in real time,” Lamb says. “Meeting these modern expectations through manual trading is no longer realistic at scale.”
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.
About Book of Gold
In April, Interactive Games LLC, a unit of Cantor, sued DraftKings and Flutter Entertainment’s FanDuel, alleging the two largest domestic online sportsbook operators infringed on its patents. That suit arrived a decade after Interactive Games brought similar litigation against the sports wagering giants, which was challenged by both companies.
In the suit brought earlier this year, the Cantor unit accuses the two gaming companies of infringing on five of its patents and requested an undisclosed amount of financial damages.
Interactive Games was once a part of Cantor Gaming, which no longer operates. That entity was familiar with controversy, enduring allegations of money laundering and nearly losing its Nevada license in 2018. The parent company sold the business in 2019.
