LeBron James will earn $15 million a year from Polymarket, nearly four times his 76ers salary, after $270 million in trading tied to his future, amid New York legal scrutiny.

Key Points:

  • James' Polymarket agreement pays $15 million annually, nearly four times his expected 2026-27 salary with the Philadelphia 76ers.
  • James is an endorser, not an investor, and his promotional work will focus on football rather than basketball.
  • New York sued Polymarket in September, alleging the platform operates an illegal, unlicensed gambling business in the state.

Polymarket Deal

Front Office Sports reported that LeBron James will receive $15 million annually from Polymarket under an endorsement agreement whose full length has not been disclosed. One source described it as an “ongoing engagement” with multiple “deliverables,” including social media posts and other content. James is an endorser rather than an investor.

The payment dwarfs his NBA salary. He signed a two-year, $8 million contract with the Philadelphia 76ers in Jul. and is expected to earn slightly less than $4 million from the team during the 2026-27 season.

James was already a major subject on prediction markets before the endorsement, giving the partnership an unusual connection to trading tied directly to his career. Contracts on where he would play next generated more than $270 million in volume this summer, including more than $45 million on Polymarket, The Athletic reported.

The agreement will focus on football, not basketball. There is no evidence it violates NBA rules or involved the 76ers, while Derek Jeter and Eli Manning also have smaller Polymarket endorsement agreements, Front Office Sports reported.

NBA Rules

The legal dispute extends beyond James. New York Attorney General Letitia James sued Polymarket on Sept. 24, accusing the company of operating an illegal, unlicensed gambling business in the state. The lawsuit seeks to stop Polymarket from operating as an unlicensed gambling business in New York and asks for fines, forfeiture of alleged illegal gains and restitution.

Prediction markets operate under federal regulation, while traditional sports betting is generally regulated by individual states, creating an active dispute over who has authority over sports-event contracts. New York is challenging that model.

NBA Commissioner Adam Silver has said players may own limited stakes in prediction-market and gambling companies, with investments capped at 1%, although LeBron James' arrangement is an endorsement rather than an investment. San Antonio Spurs star Victor Wembanyama has taken a harder public position, saying, “I will never do that,” and adding, “Honestly, I think it's very sad to see some players promote it.”

Polymarket's sports push predates the James deal. The company had already secured partnerships with MLB and the NHL, while the NBA had not announced a similar agreement and the NFL had resisted such ties.
