The number that led every report was $12.5 billion. The number that will decide the outcome is 17.8% - the Buss family's remaining stake in the Los Angeles Lakers, and the only block in the capital structure whose sale requires three separate parties to agree.
A franchise sale at this scale is not one transaction. It is a stack of consents running in series, and money clears exactly one of them.
What is agreed, and what is not
Mark Walter agreed to sell a majority interest in the Lakers to Joshua Kushner and Bob Iger at a reported valuation of about $12.5 billion, per Sportico. Walter had acquired control himself at a reported $10 billion - agreed in June 2025 and announced by Guggenheim on 25 June 2025 - which was a record at the time.
That transaction is a separate matter from the fight now in front of a judge. The dispute concerns the Buss family's remaining minority stake, reported at 17.8%. One note of caution on that figure: reporting on the 2025 transaction described the family as retaining roughly 15%, while reporting on the current sale consistently cites 17.8%. The two numbers may reflect different instruments or different measurement dates, and neither has been confirmed here against a filed document. Every valuation below should be read with that caveat attached.
Control is not ownership
The mechanism most coverage skips is NBA governorship, and without it none of this makes sense.
Each NBA club designates a governor to represent it before the Board of Governors. Governorship is conferred through the league's own approval process, not by the capitalisation table. This is why a minority holder can be a franchise's controlling owner - Jeanie Buss has held that role while the family's equity has been a minority interest - and why buying a majority of the equity does not automatically deliver control of the club.
Any transfer of control requires approval from the other clubs under the NBA constitution, whose full text is not public. What is not in doubt is that the league is a distinct consent, held by parties who are not in the courtroom, and that it is unbound by whatever a California probate judge decides. Sportico's coverage makes the point directly: the sales process 'will ultimately require NBA approval.'
The trust against the order
Two instruments govern the 17.8%, and they were never drafted to be read together.
The first is a 2017 California court order. Jeanie Buss's counsel, Adam Streisand, argues that under it she remains the Lakers' controlling shareholder and that no sale can proceed without her consent.
The second is the family trust, which per CNBC and Sportico requires approval from all three co-trustees - Jeanie, Janie and Joey Buss - before the stake can be sold.
In August, Jeanie Buss petitioned Los Angeles Superior Court to block her five siblings - Jim, Johnny, Janie, Joey and Jesse - from voting to sell, to remove Janie and Joey as co-trustees, and to hold the siblings in contempt, alleging violation of the 2017 order and of the trust's express provisions. Those are allegations in a pleading. They have not been tested, no ruling has issued, and no hearing date has been publicly reported as of 14 September.
The siblings' case, made properly
The reflexive framing casts five siblings cashing out against one defending the family legacy. The other side of it is stronger than that framing allows.
Five of six beneficiaries want to convert an illiquid minority interest into cash at the highest valuation the asset has ever carried, at a moment when a willing buyer is at the table. A trust exists to serve its beneficiaries. Read literally, a unanimity requirement hands any single co-trustee a permanent veto over a multi-billion-dollar asset - and a co-trustee who also holds the operating role has interests in that asset that the other beneficiaries do not share. Courts are not uniformly enthusiastic about readings that produce indefinite deadlock against the majority of beneficiaries.
The sharpest version of the siblings' distinction concerns scope: the 2017 order addressed governance of the franchise, not a later sale of a minority equity interest to a third party. If that distinction holds, the order does not reach this transaction at all and the trust provision is the only question. Sportico's legal analysis treats the interaction of the two instruments as the live issue rather than a formality, which is the correct read.
What the disputed block is actually worth
Nobody has put the two numbers side by side, and the comparison is the whole point.
- At the current deal's reported $12.5 billion valuation, a 17.8% stake implies roughly $2.2 billion.
- At the $10 billion valuation on Walter's 2025 acquisition, the same 17.8% implied about $1.78 billion.
- The difference - on the order of $445 million - is what the contested block gained in valuation terms between the two transactions.
So the block at the centre of the litigation represents under a fifth of the headline figure. It is the smallest consequential position in the structure. It is also the only one that cannot move without three signatures, and the only one attached to the governorship. The control premium in this deal sits on the stake that is hardest to sell.
What each outcome actually produces
If the court sides with Jeanie Buss, the 17.8% stays where it is. Kushner and Iger would close on Walter's majority position while holding a franchise whose governor controls a block they cannot buy - an arrangement that works only for as long as the parties want it to.
If the court sides with the siblings, the stake moves and the governorship question goes to the league regardless. The Board of Governors would then be deciding not merely who owns the Lakers but who speaks for them.
Either way, the league consent is the last gate and the least discussed. A California court can determine who may sell what. It cannot determine who the NBA will accept as a governor, and the two questions are answered by different people under different rules.
The lesson generalises past the Lakers. In closely held sports franchises, the operative documents are usually a trust instrument, a court order from an earlier family dispute, and a league constitution - three texts written at different times by different drafters for different purposes, none anticipating the others. A price, however large, resolves none of that. It only establishes what the parties are arguing over.
