[Sources: LeBron James' Contract with Polymarket Worth $15 Million Annually, Focuses on Promoting American Football] According to Front Office Sports, Polymarket's newly announced partnership with LeBron James will pay James $15 million annually, surpassing his earnings from playing for the 76ers. Sources indicate that James is not an investor in Polymarket but serves solely as a spokesperson. The exact duration of the agreement remains unclear. Additionally, this is described as an 'ongoing collaboration' involving multiple 'deliverables' (such as social media posts and other content). Under the agreement, James' promotional focus will be on American football rather than basketball. In July of this year, James signed a two-year, $8 million contract with the 76ers.
