The latest member of the billionaire club is a slam dunk.

LeBron James, the prolific four-time NBA champion whose business ventures include a multi-purpose entertainment company, is officially a billionaire, Forbes reported Thursday.

James boasts pretax earnings of $1.2 billion, according to Forbes, making him the first active NBA player to reach the billionaire threshold.

The financial outlet says James’ stake in his SpringHill Company — which has produced films such as “Space Jam: A New Legacy” and the upcoming “House Party” — is worth $300 million, and values his multiple pieces of real estate at $80 million.

The Los Angeles Lakers star, who has signed NBA contracts worth nearly $400 over the course of his 19-season playing career, is also said to have $500 million in cash and other investments, while his stake in the Fenway Sports Group is valued at $90 million.

In 2014, James told GQ that the prospect of becoming a billionaire was his “biggest milestone.”

“I want to maximize my business,” James said at the time.

James, 37, has recorded the second-most points in NBA history with 37,062, and the seventh-most assists with 10,045. He won two NBA titles with the Miami Heat, one with the Cleveland Cavaliers, and one with the Lakers.

James also starred in “Space Jam: A New Legacy,” which came out last year.
