Steve Ballmer's Aspiration Problem Just Got a Whole Lot Messier, and the NBA Investigation Is Already Talking

The NBA's investigation into whether the LA Clippers circumvented the salary cap through a sketchy endorsement deal with Aspiration just moved into a new phase, and it's not looking good for Steve Ballmer. Attorneys for the league submitted a letter to a federal judge detailing how thoroughly the Aspiration co-founder cooperated with the probe, laying out evidence that could reshape what we know about how this whole thing went down.

The Cooperation That Changes Everything

David Anders, the attorney leading the NBA's investigation, made it crystal clear in an April 17 letter to U.S. District Judge Stephen V. Wilson that Joseph Sanberg, co-founder of the now-defunct green banking company, sat for two in-person interviews and handed over documents. Anders wrote that Sanberg provided "information that was relevant to our investigation" and that his cooperation "substantially assisted our investigation, including our ability to develop a more complete understanding of key events."

Here's the thing: Anders specifically noted that Sanberg's information lined up with what the NBA already had. "In all our dealings with Mr. Sanberg, both directly and through his counsel, he provided information that was consistent with our review of contemporaneous documents and other evidence," Anders wrote. No backroom deals, no promises made in exchange for the help. Just clean cooperation.

What This Was Actually About

Back in September 2025, podcaster Pablo Torre reported using internal documents that Kawhi Leonard's $28 million sponsorship deal with Aspiration was designed to circumvent the salary cap. Torre's reporting showed that Ballmer had personally invested $50 million in Aspiration seven months before Leonard's deal came through. Now Sanberg is facing sentencing April 27 in federal court downtown Los Angeles after pleading guilty to two counts of wire fraud for defrauding investors out of $248 million. Each count carries a maximum of 20 years in prison.

This letter from the NBA's lead investigator is the league's first public statement about the probe, and it signals that the investigation has teeth. With Sanberg cooperating fully and the timeline clear, the dominoes are falling fast for Ballmer's Clippers.
