About Monster Mash Cash
Americans wagered nearly $167 billion on sports in 2025 through regulated sportsbooks, an 11% increase year-over-year, according to data from the American Gaming Association (AGA).
The blurring line between financial investing and gambling has been accelerated by the rise of prediction markets—exchanges offering event contracts that are federally regulated as financial derivatives. U.S. News found that over 40% of active sports bettors now also participate in sports prediction markets.

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.
“That said, channel checks indicate prediction markets are spending heavily on digital marketing, including app stores and pay-per-click advertising, which could make our forecast look conservative by the end of the season,” EKG concluded.
