LeBron James signs with Philadelphia 76ers and partners with prediction market Polymarket.

James’s two-year Philadelphia contract includes a player option for the 2027–28 season, allowing him to decide whether to remain with the 76ers after the first two years.
The 76ers’ acquisition of Jaylen Brown reportedly helped make Philadelphia attractive to James, with the team offering a deep roster and an opening at power forward; the article contrasts that fit with alternatives such as Miami and Minnesota.
James had reportedly earned more than $580 million from NBA contracts before joining Philadelphia, putting his veteran-minimum deal in the context of his unusually large career earnings.
Polymarket declined to comment on the reported agreement, while a representative for James did not immediately respond to requests for comment.
The deal comes as prediction-market competitors intensify their sports marketing: Kalshi featured former NFL running back Marshawn Lynch in an advertisement and counts NBA star Giannis Antetokounmpo among its investors, while sports-focused Novig released a provocative campaign featuring actress Sydney Sweeney.
LeBron James took a dramatic pay cut to join the Philadelphia 76ers on a two-year veteran-minimum deal worth about $7.9 million, but he's making up for it elsewhere. Daily Mail reports James signed with prediction-market company Polymarket for roughly $15 million annually—nearly four times his NBA salary—to create social-media content and sports promotions.
The Polymarket partnership marks a striking reversal from James's earlier warnings about gambling and sports integrity. The deal joins a wave of sports-marketing spending by prediction-market companies competing for attention, featuring Derek Jeter, Eli Manning, and Rajon Rondo alongside James.
James left the Los Angeles Lakers after his career earnings topped $580 million, according to USA Today. The 76ers' roster depth—highlighted by their acquisition of Jaylen Brown—made Philadelphia the most attractive destination. The deal includes a player option for 2027–28, letting James decide his future after year two.
At 39 years old, James prioritized winning over salary. A veteran minimum pays only $3.9 million for 2026–27, a fraction of what supermax contracts offer. Yet USA Today notes this may be the best value contract in league history—James remains one of basketball's elite players despite the reduced pay.
Total Pro Sports reports the Polymarket deal pays James $15 million per year—roughly four times what the 76ers pay him. Neither Polymarket nor James's representatives confirmed the partnership details. The arrangement requires him to promote prediction markets through social media, ads, and sports-focused content.
Prediction-market companies are competing fiercely for sports fans' attention. Kalshi featured former NFL running back Marshawn Lynch in ads and counts NBA star Giannis Antetokounmpo as an investor. The sports-focused Novig released a provocative campaign with actress Sydney Sweeney.
James previously warned that gambling undermines sports integrity. Yet his Polymarket deal puts him at the center of prediction markets—largely unregulated platforms that some critics say expand risky wagering access. The partnership highlights a growing tension between athlete influence and responsible sports betting.
Prediction markets operate in legal gray zones in many states. Critics worry these platforms could fuel problem gambling, particularly among younger fans who follow celebrity endorsers. James's $15 million paycheck raises questions about whether athlete endorsements prioritize short-term earnings over long-term harm.
