LeBron James has signed on with Polymarket. The deal makes him the newest professional athlete to team up with a prediction market platform.
James will make weekly NFL picks as part of the partnership. The agreement was announced earlier this month.
The Polymarket campaign includes several other retired sports stars. Sue Bird, Reggie Bush, Derek Jeter, Eli Manning, Rajon Rondo, and Richard Sherman all appear in the ad.
Filmmaker Spike Lee is also part of the promotional push. His involvement adds another recognizable name to the campaign.
James previously worked with DraftKings Sportsbook. That earlier partnership put him on the other side of the betting industry.
Three years ago, James spoke out against how online sportsbooks were changing the sport. He said betting was taking some of the integrity out of the game because fans cared more about their wagers than the outcome itself.
His new deal with Polymarket is reportedly worth $8 million over two years. The switch marks a change in tone from his earlier comments.
Polymarket Faces Off With Kalshi
Signing James and the other athletes was a win for Polymarket. The company has trailed rival Kalshi in valuation, trading volume, and athlete partnerships.
Giannis Antetokounmpo has his own deal with Kalshi. His agreement reportedly includes an ownership stake in the company.
Golfer Bryson DeChambeau and soccer star Lionel Messi also serve as Kalshi brand ambassadors. Both deals were announced over the summer.
Kalshi recently struck agreements with five Major League Baseball teams. Those teams are the Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants.
Polymarket, meanwhile, was named MLB’s exclusive Official Prediction Market Exchange back in March. Both companies now hold ties across multiple major sports leagues.
What a Legal Ruling Could Mean
The legal battle between prediction markets and individual states is still playing out. Courts have not settled whether sports event contracts can continue in their current form.
A Supreme Court ruling against these contracts could change the picture for both companies. Deals tied to sports picks and predictions would lose their main function.
Prediction markets would likely continue operating even without sports contracts. But the industry would look much smaller without that business.
For now, both companies continue expanding their reach through athlete endorsements and league partnerships. The outcome of the ongoing legal cases will determine how long that growth continues.
