“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.
