It’s widely believed that all-or-nothing exchanges are carving out significant niches in states, such as California and Texas, where sports betting is prohibited, but there’s also emerging consensus that the prediction market threat to sportsbooks is easing.
A major advantage for traditional sportsbook operators is their ability to aggressively fund customer acquisition and retention bonuses. As EKG points out, prediction markets have “less ability to be generous with bonuses” because users trade against one another rather than against the house.
That creates a stark contrast during peak football season when traditional sportsbooks spend heavily on promotions. Offers ranging from $350 to $365 from major operators make the $25 to $50 promotional matches typically seen on prediction markets appear modest by comparison.

Unlike regulated sportsbooks, prediction markets allow customers between the ages of 18 and 21 to trade on sports-event contracts. Craig Carton, a sports talk host with WFAN 660 AM in New York, criticised the athletes for their endorsement of Polymarket. Carton, a recovering compulsive gambler, opined that the “unregulated” gambling markets are driving Americans into bankruptcy and kids out of school. Regulated books prohibit those under 21 from betting on their platform, leading Carton to question the celebrities for promoting the company.
