LeBron James took the smallest contract of his career this summer to chase one more championship in Philadelphia. The strangest money in his life right now isn't in that contract — it's in the endorsement he signed with Polymarket, and this week that deal stopped being a business story and became a controversy.
Polymarket has removed a market from its international platform that let users bet on whether any of the seven Cornell fraternity members accused in a gang-rape lawsuit would be charged with a felony sex crime. According to the New York Post, the company pulled the market after the Post sought comment, as backlash from sexual-assault advocates mounted. Before it came down, the market had drawn roughly $451,633 in trading volume, with traders pricing the chance of charges at about 28 percent, Front Office Sports reported.
Advocates did not stop at the company. The nonprofit I Have The Right To and attorney Cheyenne Hunt publicly pressed Polymarket's celebrity endorsers — a roster that includes James, Derek Jeter, Eli Manning, Sue Bird, Reggie Bush and Richard Sherman — to denounce the market and reconsider their deals. Hunt called the market "dehumanizing, disgusting, and dangerous" and asked the company's ambassadors whether they really wanted to be associated with it. A petition urged the endorsers to sever their relationships with the platform entirely. Representatives for the athletes did not immediately respond to requests for comment, according to Front Office Sports. On Tuesday, Sporting News published an explainer of James's contract with the platform, and screenshots of it were circulating widely on Facebook — a sign of how quickly the story has moved from the business pages to the fan conversation.
The deal: $15 million a year, no equity, football only
The deal at the center of it was reported last month. Front Office Sports reporters Ryan Glasspiegel and Ben Horney reported on September 16 that James had signed a multiyear endorsement agreement with Polymarket worth a reported $15 million a year. The structure matters: James is an endorser only, with no equity in the company, and his promotional work focuses on football rather than basketball — the same posture his previous betting partnership took. His deal with DraftKings expired this summer.
Now put that number next to his basketball money. In July, James signed a two-year, $8 million contract with the Philadelphia 76ers that pays him roughly $3.9 million this season — the smallest deal of his professional life, and a small fraction of the money he commanded at his peak. Spotrac puts his career on-court earnings at $581.4 million, so this was never about needing the money. Philadelphia's cap sheet is crowded with star salaries, and James's discount was part of the fit. But the arithmetic still startles: a prediction-market company is paying him about four times what the 76ers pay him to play basketball.
The loop: the platform profited from bets on his decision, then hired him
There is also a loop here that makes league executives uneasy, and it's worth stating plainly. This summer, as James's free agency became the sport's biggest guessing game, Polymarket reportedly took in more than $43 million in wagers on his next destination, according to Front Office Sports reporting. The platform profited from the world's speculation about his decision. Now it pays him to promote the platform. Nothing about that arrangement was secret, and endorsement deals between athletes and betting companies are now routine across sports. But the sequence — the market on his future first, the paycheck second — is exactly the kind of entanglement critics point to when they ask how close is too close.
Not everyone around the league sees a scandal. Draymond Green told Front Office Sports reporter Olivia Arciniega that criticizing players for signing these deals while the leagues themselves hold betting partnerships is "hypocritical." His point, paraphrased, is that players are being singled out for doing at an individual level what their leagues already do at an institutional one — and that the outrage tends to land on the famous faces rather than the structures that invited them in.
He's not alone — the prediction-market ad war has arrived
James is hardly alone in this economy, and the rivalries are already absurd. Giannis Antetokounmpo is not merely an endorser but a shareholder in Kalshi, Polymarket's chief rival, while earning $58.5 million this season with the Miami Heat. On opening night, Dillon Brooks fronted a Kalshi advertisement for a fictional "King Blocker 9000" that openly mocked James. Two of the most famous players alive are now paid by competing prediction markets — one owns a piece of his, one rents his fame to his — and the ad war between the platforms is being fought with their faces.
A note of transparency from us: Polymarket is one of the market sources carried on our Vegas Board, where we track prices from multiple sources for readers who follow that world. We cover this platform because it is news; we list its markets because readers use them. Both things are true at once, and readers deserve to know it.
What happens next is an open question. James and his camp have not publicly addressed the Cornell market, and the advocates' campaign is aimed squarely at changing that. The endorsement itself runs multiple years, and the league's rules — which permit players to promote prediction markets so long as they stay away from their own sport's markets — currently allow it. For now, the math remains the story. The most famous basketball player on earth took a pay cut to chase a ring, and the company paying him four times his salary to lend it his name just learned, in public, that in the prediction-market business the product is the questions you choose to ask.
