LeBron James' newest business deal is reportedly bigger than his NBA salary this season.
Front Office Sports reported that Polymarket is paying James $15 million per year under its recently announced partnership with the 76ers star. The report says James is not an investor in the prediction-market company. He is being paid as an endorser, with one source describing the agreement as an ongoing engagement built around multiple deliverables, including social media posts and other content.
That number stands out because James' current playing contract is modest by his standards. He signed a two-year, $8 million deal with Philadelphia in July, putting his expected 2026-27 salary at a little under $4 million. If the Polymarket figure is accurate, the endorsement pays him nearly four times what the 76ers will pay him this season.
The basketball angle is not the only strange part. According to FOS, James is expected to focus on promoting football, not basketball, as part of the deal. That fits the timing. Prediction-market platforms are pushing hard for attention around the start of football season, and Polymarket used a celebrity-heavy commercial to announce the campaign.
Derek Jeter and Eli Manning also appeared in that commercial and are reportedly being paid through smaller endorsement deals than James. The spot included several other public figures, including Spike Lee, Reggie Bush and Alexandra Daddario, though FOS reported it was not clear which participants had long-term deals and which were paid only for the commercial.
Polymarket declined comment to Front Office Sports, and a representative for James did not immediately respond to the outlet. That leaves the reported salary as the cleanest piece of information available, but not a fully public contract breakdown. The length of James' agreement also remains unclear.
The deal lands in the middle of a bigger sports-business fight. Polymarket and Kalshi already have official relationships in major leagues outside the NBA. Polymarket is MLB's exclusive prediction-market partner, while Kalshi is recognized under MLB's integrity framework and has been able to make team-level deals. Both companies are also official NHL partners.
The NBA has not formally moved that far yet. FOS reported that the league is closing in on prediction-market agreements, while the NFL remains more resistant. That matters because James is not just any endorser. He is still one of the NBA's most visible players, and his paid push for a prediction-market company arrives before the league has fully planted its own flag in the category.
There is also a regulatory cloud over the industry. Prediction markets are regulated federally, but they have drawn lawsuits and challenges because sports-event contracts can look very similar to sports betting, which is usually handled state by state. Attorneys general in New Jersey and Nevada, other states and several Native American tribes have been part of that broader pushback. The central legal question could eventually reach the Supreme Court.
For James, the immediate takeaway is simpler. His NBA contract with Philadelphia is no longer the biggest annual check tied to his name this season. If FOS' reporting holds, Polymarket is paying him like a centerpiece of its sports push, even while the NBA is still deciding exactly how close it wants to get to prediction markets.
