NBA salary cap probe nears conclusion as investigators interview Leonard, Ballmer and Aspiration executives

NBA investigators have conducted interviews with LA Clippers star Kawhi Leonard, his business adviser Dennis Robertson, team owner Steve Ballmer, and executives from the now-defunct green banking company Aspiration. The inquiries form part of a probe into allegations that the franchise circumvented the salary cap to compensate Leonard through a sponsorship arrangement with the financial firm.

Commissioner Adam Silver confirmed the investigation is in its advanced stages, stating the league is close to concluding the matter. Silver emphasised that the outcome will clarify the regulatory environment for the Clippers and the other 29 NBA teams, though he did not provide a specific timeline for the final announcement. The probe was initiated in September 2025 following reports citing internal documents regarding Ballmer’s personal investment in Aspiration and subsequent sponsorship deals involving the team and Leonard.

Publicly, the Clippers and Ballmer have maintained their innocence, denying any evidence of wrongdoing. However, sources indicate that some team officials have grown frustrated by the difficulty of proving their innocence regarding a violation they assert they did not commit. Despite their certainty of innocence, there is uncertainty surrounding the final outcome and whether the league’s richest owner will face sanctions.

Under the 2023 collective bargaining agreement, penalties for salary cap circumvention can include fines of up to $7.5 million, forfeiture of draft picks, voiding of player contracts, or suspensions of up to one year for team personnel. The National Basketball Players Association (NBPA) is expected to vigorously oppose any punishment, particularly if it involves charges of negligence or conflict of interest, which sources describe as legally complex.

The NBPA’s resistance stems from the fact that NBA teams are prohibited from having knowledge of player sponsorship deals outside of the team, per the NBA Operations Manual. Punishing the team for a conflict of interest is also viewed as a "slippery slope" given other instances of separate sponsorships between teams and players. If the team disputes a lesser punishment, it may seek the intervention of a system arbitrator appointed by the NBA and NBPA.

Sources suggest Commissioner Silver is focused on ensuring the outcome is perceived as fair by other owners to avoid setting a worrying precedent. The league’s legal team, Wachtell, is expected to deliver a final report, and Silver is reportedly prepared to accept the findings if they do not support clear evidence of guilt, prioritising the stability of the league’s governance over public pressure.
