In 2018 the US Supreme Court struck down the federal law that had kept sports betting largely confined to Nevada, and states began to legalise it one by one. Within a few years, betting had moved into the sporting venues themselves. A retail sportsbook opened at Capital One Arena in Washington in 2021, and other stadiums and arenas followed in the states that allow it.

Why this matters to marketers

Stadiums have long been a favourite setting for mobile promotions, with fans entering draws for seat upgrades using their phones. Sportsbook operators now work in that same setting, with very high stakes for accurate customer data, so they have become unusually good at things other marketers often do poorly.

Three habits worth noting

  • Location checks. Mobile betting apps must confirm that the user is inside a permitted state or zone. Fan apps can use a much lighter version of the same idea, offering seat-side extras only to those actually in the venue.
  • Identity at sign-up. Sportsbooks must verify who their customers are. Few fan promotions need that, but they could learn from how smoothly the good apps guide users through a long form.
  • Timing. Odds and offers change by the minute around a live game. Fan messages sent at half-time or right after a big play get attention that a next-day email will not.

What not to copy

Betting promotions face strict rules on who may be targeted and how, and they get a good deal of public scrutiny. Fan marketing often involves families and younger audiences. Keep the two clearly apart: a draw for a signed shirt at a family game should not be mixed with a betting offer, and organisers should check any sponsor's activity against league and state rules.

Data you can actually use

For an event marketer, the real lesson is about the moment of capture. A sportsbook knows that the fan who is engaged during a game is its best prospect. So does a sponsor with a tap-to-enter sign on the walkway. Keep the form short, send the follow-up during the excitement and then measure what those fans went on to do.
