The shift means that rather than spending their time pricing and managing established markets, traders can now apply their expertise where human judgement has the greatest value, including developing and testing new products. AI removes many of the practical limits on what can be offered and priced, and manages the resulting scale and complexity. The result is greater efficiency for Kambi and a better service for its partners and their customers.

“To this point, sportsbook product creation has largely been guided by a trading department’s ability to profitably price and risk-manage certain bet offers,” Lamb says. “AI trading lifts those limitations, while also enabling that existing human expertise to be leveraged more effectively.”

The 2026 tournament demonstrated why Kambi believes this total integration of AI is necessary. Sportsbooks are no longer built primarily around match results and traditional pre-match markets. Bettors increasingly expect to construct wagers around individual players and specific moments within a game.

Operators must maintain permanent mechanisms for age verification, self-exclusion, voluntary time and wagering limits, and information on the user’s own gambling behaviour. Self-exclusion must be effective with all authorised operators. 

The text also prohibits bets placed using credit cards, the use of predictive models to identify moments of greater vulnerability, and platform design mechanisms that hinder a conscious decision to stop betting, leave the service, or activate limits and blocks. Operators must maintain permanent alerts about compulsive gambling, indebtedness and asset loss, and adopt verifiable protocols for identifying risky behaviour.  

The proposal establishes criteria for classifying products according to their potential for harm. Among the characteristics considered are instantaneous or short-lived results, continuous repetition at short intervals, use of random mechanisms to determine the outcome, intermittent rewards, near-miss incentives, incentives to recover losses and features that make it difficult to stop betting or induce successive, impulsive, or increasingly valuable bets.

At the same time, prediction market operators are facing regulatory tussles in the US. State regulators are moving to shut down the firms under gambling laws. The companies say their contracts should be regulated at the federal level as derivatives. 

However, the sector has grown substantially despite such disputes. Bernstein predicted in April that annual prediction market volume could reach $1 trillion by 2030. The research estimated volume was around $51 billion in 2025 and could grow to around $240 billion in 2026. 

The partnership with Yahoo Finance wraps up as prediction markets push for broader distribution across financial media, sports, and entertainment platforms. For Polymarket, the loss of the Yahoo Finance hub is one distribution channel, but other partnerships remain intact.
