LeBron James announced a new partnership with Polymarket with a short post on social media over the weekend.

Polymarket describes itself as the world's largest predictions market.

Giannis Antetokounmpo announced a partnership with Polymarket competitor Kalshi earlier this year.

James is the first NBA player to sign with Polymarket. It is not clear exactly what his role entails.

It was reported last week that the NBA is finalizing multiple predictions-market partnerships ahead of this upcoming season.
