The league announced the punishment on Wednesday following an investigation led by an outside law firm that began in September 2025. The probe examined whether a US$28 million endorsement contract between Clippers star Kawhi Leonard and Aspiration Fund Adviser LLC, a company that later filed for bankruptcy, violated league rules.
Alongside Ballmer's one-year suspension and the team fine, the NBA banned president of basketball operations Lawrence Frank for six months and suspended team president of business operations Gillian Zucker for one year. Leonard, a two-time NBA Finals MVP, was fined US$700,000 ($977,000).
The penalties drew an immediate and strongly worded response from the Clippers, who had repeatedly maintained they were innocent. In a statement, the team said it "vehemently rejects" the NBA's findings, describing the investigation as "a heavily biased investigation seeking to justify a predetermined narrative rather than facts and evidence." The Clippers said they will "vigorously challenge these findings and penalties through every avenue available to us."
Earlier in the process, Leonard and Frank expressed confidence they would be cleared. "I think that we're going to be in the clear, so I'm not stressing it," Leonard said in April. Frank said of Ballmer: "If you know Steve and know Steve's integrity, you know there's nothing to it."
The league, however, said it and the players' union had agreed to confirm the penalties as final and binding on all parties. Commissioner Adam Silver said he was "deeply disappointed by the flagrant violations of our rules," adding that "the severity of the penalties reflects the seriousness of the violations."
The league said the outside law firm continues to receive information related to the investigation and "will consider further action as appropriate."
The Clippers also released a letter from Ballmer's attorney, David Kelley, to Silver, in which Kelley described the investigation as "a witch hunt."
Aspiration co-founder Joseph Sanberg was sentenced earlier this year to 14 years in federal prison after pleading guilty to defrauding investors and lenders of at least US$248 million.
