What is Book Of Monsters?

A survey by Fullstory, a behavioral data analytics company, says that amid the evolution of yes/no exchanges, 60% of bettors said prediction markets are altering how they use sportsbooks with 35% admitting that they’ve reduced usage of traditional sports wagering platforms as access to sports event contracts increased.

“Consumers are being presented with more options for how they can participate in online gaming, creating a more competitive landscape where a seamless digital experience is increasingly becoming part of the value proposition,” said Jason Wolf, president of Fullstory, in a statement. “The brands that understand how consumers are navigating, comparing, and engaging with their platforms in real-time can identify where friction is getting in the way of trust and retention.”

A quarter of respondents said they use both prediction markets and sportsbooks depending on the event they’re considering wagering on. While the 35% reduced use figure may sound like a warning shot to gaming companies, a variety of other studies and surveys indicate that when bettors can choose between a sportsbook and an all-or-nothing exchange, they frequently opt for the former.

Industry consultant Jari Vähänen, formerly a senior executive at Veikkaus, estimated the entire business could be valued at up to €4.5 billion following the liberalisation of the market.

Veikkaus is adjusting to a partial liberalisation of Finland’s gambling market under the new Gambling Act, which was ratified in January 2026. 

From July 2027, the company will lose exclusivity over betting and iCasino products, which will become licence-based, while retaining exclusive rights for lottery games, scratchcards, slot machines and physical table games.
