The research firm estimates that by 2035, financial derivatives, including event contracts linked to commodities, cryptocurrencies and stocks, will account for 49% of turnover on yes/no exchanges, topping sports to become the largest volume driver.

“We expect new products such as KPI markets, which allow users to trade a single corporate metric, such as production, deliveries, or subscriber growth, rather than the stock price itself,” observe the analysts. “Further, perp futures are expanding from crypto to commodities and single stock perps.”
Some exchange operators already filed plans to introduce KPI-linked event contracts. Those derivatives would be tied to metrics such as corporate earnings or, in more nuanced cases, Apple iPhone shipments or Tesla deliveries — just two examples — in a given quarter.

Kambi’s path to the 2026 World Cup began with its initial investment in AI trading technology in 2021. The platform was deployed at scale during the Qatar 2022 tournament and fully embedded within its trading operations by 2024.
By 2026, the technology had already been tested across several seasons of top-level competitions including the Premier League and Champions League. AI now trades more than 70% of bets across Kambi’s network, including all football and tennis.
The 2026 World Cup was therefore the culmination of five years of development that had embedded AI throughout Kambi’s trading operations.
