LeBron James has moved on from a partnership with DraftKings to a new deal with Polymarket reportedly worth $15 million, according to the source. The deal underscores a broader cultural shift that sees top-tier athletes and high-profile celebrities routinely promoting legal sports betting and prediction platforms to millions of consumers.
Celebrity Endorsements and the Normalization of Betting
Top athletes and entertainers including Tom Brady, Kevin Hart, Jamie Foxx, Derek Jeter, Sydney Sweeney, Charles Barkley, Shaquille O’Neal, Eli Manning, Timothée Chalamet, Jon Hamm, and Spike Lee have appeared in advertisements for sports books like DraftKings, FanDuel, and BetMGM, as well as prediction markets such as Kalshi and Polymarket. Mark Gottlieb, executive director of the Public Health Advocacy Institute at Northeastern University in Boston, said that these celebrity endorsements are inherently deceptive in how they normalize online gambling as a fun and safe product.
This marketing approach draws direct comparisons to mid-20th-century tobacco campaigns. During that era, cigarette companies paid sports heroes and movie stars—including Ronald Reagan, Ted Williams, Willie Mays, Mickey Mantle, Joe DiMaggio, Joe Louis, and Bob Cousy—to portray smoking as part of a happy and healthy lifestyle. Gottlieb noted that online gambling platforms are deploying that exact same tactic to capture new customers and secure their loyalties.
The Expansion of Legal Wagering Across States
The current landscape of digital betting accelerated following the U.S. Supreme Court’s 2018 decision to lift a federal ban on sports wagering. Since that ruling, 39 states and the District of Columbia have approved online sports betting. This widespread legalization has enriched a consortium of three powerhouse industries, uniting sportsbooks, prediction markets, professional sports leagues, and major sports media networks.
Recent data indicates that more than half of men aged 18 to 49 currently maintain an account with an online gambling platform. Concurrently, calls to gambling addiction helplines have increased nationwide. Unlike traditional wagers on game winners or point spreads, modern platforms utilize artificial intelligence and league statistics to offer microbets. These allow users to wager throughout a game on granular details like the velocity of an individual pitch, increasing the speed and intensity of the experience.
Public Health Concerns and Psychological Risks
Medical professionals caution that the rapid expansion of digital wagering carries severe psychological and financial consequences. Dr. Timothy Fong, an addiction psychiatrist and co-director of the UCLA Gambling Studies Program, emphasized that problem gambling can cause extreme harm, noting that financial loss frequently leads to profound emotional pain, shame, and embarrassment. While athletes in the 1950s often worked offseason jobs due to modest salaries, contemporary sports stars command massive fortunes, yet they continue to lend their star power to platforms that present gambling without any mention of financial loss, psychological harm, or family disruption.
