Polymarket is paying James $15 million a year under the endorsement partnership unveiled Sept. 5, per Front Office Sports.

James signed a two-year, $8 million deal with Philadelphia and is expected to make a little under $4 million from the team this season.

He is an endorser, not an investor. One source described an “ongoing engagement” with social posts and other content deliverables.

Under the deal, James promotes football and other prediction-market categories tied to Polymarket’s platform.

Prediction-market endorsements sit next to league gambling and sponsorship rules — the salary gap is what made the deal headline news.
