Prediction markets are splurging on ad campaigns featuring A-listers\u2014and the approach is starting to rankle some observers. On Wednesday, sports trading platform Novig released a video of actress Sydney Sweeney appearing nearly nude while promoting the company\u2019s sports-only offering ahead of the NFL season opener. The advertisement swiftly drew scrutiny of prediction markets\u2019 marketing tactics and efforts to increase user engagement on their platforms.<\/p>\n

\n

The advertisement came a day after Polymarket enlisted basketball star LeBron James for a star-packed football-season commercial featuring other prominent athletes, including Eli Manning and Derek Jeter, along with entertainment figures such as filmmaker Spike Lee and model Emily Ratajkowski.<\/p>\n

\u201cSelling gambling by selling sex. Society is crumbling before our eyes,\u201d one user wrote of Novig\u2019s promotion.<\/p>\n

\u201cDamn, I can\u2019t believe LeBron is a sellout now,\u201d another user wrote in response to Polymarket\u2019s ad.<\/p>\n

\n

LeBron’s Polymarket deal knocks him out of GOAT contention. The title stays with Michael Jordan, a man untainted by the allure of sports gambling.<\/p>\n

The celebrity advertising push comes as prediction markets expand rapidly across the United States, despite a contentious legal and regulatory fight. The platforms let users buy and sell contracts on outcomes ranging from sports and politics to pop culture, often with just a few clicks. Their rapid growth has intensified scrutiny over whether sports-related contracts should be treated as federally regulated financial products or gambling under state law.<\/p>\n

To sustain that momentum, prediction market companies are pouring money into high-profile marketing campaigns. Kalshi and Polymarket\u2014two of the sector\u2019s largest players, each valued at roughly $20 billion\u2014have spent heavily to recruit celebrities to promote their platforms. Because sports-related contracts account for a large share of activity on their platforms, the companies have timed major campaigns around the start of major sports seasons.\u00a0<\/p>\n

In the lead-up to the World Cup, soccer\u2019s biggest international tournament, Kalshi ran ads featuring Argentina captain Lionel Messi alongside teammates Nicol\u00e1s Otamendi and Rodrigo De Paul as part of a commercial partnership with the country\u2019s national football federation. The platform also featured Luka Modri\u0107, captain of Croatia\u2019s national team, in a separate campaign.<\/p>\n

Before that, Kalshi also enlisted Oscar-nominated actor Timoth\u00e9e Chalamet for a series of ads set in mundane places, including a dentist\u2019s office and a music store.<\/p>\n

The marketing push comes as prediction markets confront mounting uncertainty over their legal future. In August, the Ninth Circuit ruled that Nevada could enforce its gambling laws against Kalshi\u2019s sports-event contracts, rejecting the company\u2019s argument that federal commodities law preempted state oversight.\u00a0<\/p>\n

With appellate courts now divided, the dispute over who gets to regulate the fast-growing industry could reach the Supreme Court as early as next year.<\/p>\n<\/div>\n
