NBA star LeBron James announced on X that he had visited Polymarket’s headquarters and was preparing to partner with the prediction market platform. A video showed him selecting the sports category from options including crypto, economics, culture, weather and esports, suggesting the collaboration may focus on sports. The reported deal would be Polymarket’s first partnership with an individual NBA player. Existing plans call for a broader campaign next week focused mainly on American football. James’ previous DraftKings contract has ended, while about $273 million has been traded in a prediction market concerning his potential move, and some fans have criticized the partnership.
