Growth of Sports Betting and Prediction Markets Shaping March Madness

Legalized sports betting, although expanding across the country, has seen a slowdown in recent years. Growth in the annual handle on major events like March Madness has moderated, contrasting sharply with the rapid increases of previous years. According to the American Gaming Association (AGA), this year's March Madness is projected to see about $3.3 billion wagered, marking a mild 6% increase from last year. This growth is notably less robust than the approximately 50% annual increases observed over the past three years.

Prediction markets are also emerging as significant players in the betting landscape. HG Gambling Capital estimates around $500 million could be added in bets on prediction markets for the event. However, it's important to note that these markets report volume differently than traditional sports betting handle, making direct comparisons challenging.

Despite these shifts, DraftKings and FanDuel report that prediction markets haven't notably diverted business from traditional sports betting. They attribute the slowing sports betting growth more to substantial wins in the NFL and reduced promotional activity. This year’s March Madness will likely offer further insights into the evolving dynamics of betting markets, particularly in light of the industry's reactions to changes in state legalizations and market preferences.

Last year's NCAA tournament was notably predictable, with all top-seeded teams reaching the Final Four, a rare occurrence that significantly impacted the bookmakers' hold rates. Historically, bookies aim for an 8-12% hold rate, but last year's tournament saw them retaining only about 6%. The expectation for this year again leans towards favorite teams advancing, which might replicate similar betting patterns centered on safer, lower-return bets.

Among specific teams, states like Arizona and Duke have recently been top picks in several sportsbooks, pointing to a possibly top-heavy tournament ahead. Such a setup decreases the likelihood of "Cinderella" upsets that typically offer more lucrative payouts. Sportsbooks, however, are likely hoping for some underdog successes to balance their books.

Moreover, this year’s first-round matchups show all fifth seed teams favored by at least eight points, suggesting a possible continuation of the trend where top teams dominate. This evolving pattern coincides with the NCAA's recent adaptations to Name Image Likeness (NIL) policies, perhaps ushering an era with less parity among college basketball teams. How this will impact the overall excitement and unpredictability of March Madness remains a key focus for both fans and bettors alike.
