Marcus Vale: Ben, I'll tell you how I found out — my phone buzzed during a meeting, I glanced at the screen, saw 'Mark Cuban' and 'Athletics' in the same alert, and I genuinely assumed it was a parody account for about four seconds.
Ben Okonkwo: Okay, same energy — I saw it and my first instinct was to check the date, because it reads like a planted story. But it's real. July 24th, 2026, Harbinger Sports Partners announces a minority stake in the Athletics.
Marcus Vale: Cuban is general partner and president. The fund also has Rashaun Williams, Steve Cannon, Jonathan Mariner. And Mike Ozanian at CNBC puts the check at fifty million dollars.
Ben Okonkwo: Against a reported three-point-eight billion valuation for the Athletics plus the Las Vegas stadium. Which — okay, that math gives Cuban somewhere around 1.3%. That's a rounding error on a franchise.
Marcus Vale: Right, so the real question isn't whether this is smart baseball strategy. It's why a guy who owned 73% of the Dallas Mavericks — sold to Miriam Adelson and Patrick Dumont in 2023, kept 27, and then publicly says the pivot was 'not my choice' — ends up here, buying 1.3% of a team that doesn't have a home yet.
Ben Okonkwo: The 'not my choice' quote is — I mean, that's the contradiction I actually want to pull apart. He executed that sale.
Marcus Vale: He executed it. Signed it. Which means either the conditions of the deal were different than what got reported, or this is a narrative he's constructed after the fact because sitting at 27% minority with Adelson and Dumont running the show turned out to be worse than he expected.
Ben Okonkwo: And the mechanism that makes Harbinger the answer to that problem — that's what I'm not seeing clearly yet.
Marcus Vale: The mechanism missing here — it's not baseball. It's what 27% actually means when Adelson and Dumont are running the operation. You own a piece, you get the appreciation, and that's it.
Ben Okonkwo: Right — and there's a legal filing that makes this concrete. Not the emotional 'not my choice' framing. There's a filing that suggests Cuban was cut out of stadium-adjacent real estate deal flow after the 2023 sale. Meaning, actual economic opportunities tied to the Mavericks footprint — not included.
Marcus Vale: One filing. That's thin.
Ben Okonkwo: It is thin sourcing, I'll grant that. But the structure it describes — that's not unusual. Think about it this way: imagine you sell your share of a family business, your name's still on the door, you still get a dividend check. But when they decide to open a second location, nobody calls you. No seat at that table, no invite to the expansion meeting. That's not estrangement, that's the deal working exactly as written — and Cuban apparently didn't anticipate that part.
Marcus Vale: Okay, that actually — yeah, that reframes it. The 'not my choice' quote isn't about the 73% sale. It's about what came after. The minimal communication with Adelson and Dumont. The exclusion from deal flow. That's the new information.
Ben Okonkwo: Exactly — and once you see it that way, Harbinger isn't a baseball story. It's what you build when you've lost majority control and discovered that 27% buys you nothing operational. Williams, Cannon, Mariner — Jonathan Mariner was CFO of Major League Baseball, he knows how minority stakes actually function — they're constructing a vehicle to aggregate the one thing Cuban can still acquire: financial upside without control requirements.
Marcus Vale: So — and I want to push on this — one filing still isn't a pattern. What would make the structural exclusion argument actually hold?
Ben Okonkwo: A second instance, ideally. Or a disclosed communication breakdown timeline with Adelson and Dumont that we can date. Right now we have a quote, we have minimal contact on record, and we have one filing. That's circumstantial. But the circumstantial case points one direction — and Harbinger is the behavioral evidence. You don't build a PE fund to buy 1.3% of a Las Vegas team that hasn't opened its stadium yet because you love minority positions. You do it because minority positions are suddenly all you have access to.
Marcus Vale: But that behavioral evidence framing — that's actually where the wrong take lives. Because everyone reporting this is calling it a baseball story. 'Cuban gets into baseball.' That's not what happened. Harbinger was founded in 2025 with an explicit mandate: minority stakes, major North American franchises, plural. The Athletics deal is the first disclosed move. This is a fund structure, not a sport preference.
Ben Okonkwo: Right — but does the quote not complicate that? 'We are minority investors looking to make our investors a lot of money.' That's Cuban's own framing.
Marcus Vale: Does that sound like the guy who ran the Mavericks for twenty-plus years? That's not his voice. That's a PE disclosure sentence.
Ben Okonkwo: Hm. So either he means it — genuine repositioning — or it's the only publicly defensible frame when you've lost majority control and you're pitching LPs.
Marcus Vale: Picture a retired NBA coach who buys into a gym franchise. He's not running morning drills. He owns a percentage of the lease. That is the structure Cuban is inside now. Williams is the architect — he's the founder and CIO, Atlanta Falcons minority owner, met Cuban through Shark Tank. Cannon is CEO, vice chairman of AMB Sports and Entertainment. Mariner ran CFO for all of Major League Baseball. Cuban is general partner and president of a vehicle built by operators who know exactly what minority passive looks like.
Ben Okonkwo: No, that's — okay, that's the structure, but the load-bearing assumption is whether fifty million dollars against a three-point-eight billion valuation is the access fee you're describing, or whether it's actually just... a small-cap sports investment that happens to have Cuban's name attached.
Marcus Vale: No. 1.3% is not a yield play. Nobody writes a fifty-million-dollar check for 1.3% of a franchise that hasn't opened its stadium — 2028 is the target — because the dividend math works. You write that check because you want the seat.
Ben Okonkwo: And that valuation — the three-point-eight billion — that's entirely Ozanian's reporting, not a disclosed number. Which means the whole access-fee argument rests on an unconfirmed denominator. That's the part I'd watch very carefully as 2028 approaches.
Marcus Vale: Frankly — the Las Vegas comparison to the Golden Knights and the Raiders is doing a lot of work in Rashaun Williams's pitch, and I think that comparison breaks faster than anyone's acknowledging. We'll get there.
Ben Okonkwo: Right — but the comparison breaks in a specific way. Williams cites the Golden Knights, 2017, and the Raiders, 2020. Both correct. Both worked. But those franchises landed in a city with no major professional sports infrastructure. Pent-up demand, nowhere to direct it. The Athletics are arriving third. That market has already been claimed.
Marcus Vale: Third franchise, totally different ask.
Ben Okonkwo: And baseball attendance is — I mean, it's a different product. Hockey and football are event sports, sixty-odd home dates. MLB is eighty-one. Sustaining that in Las Vegas against a stadium that doesn't open until 2028 is the actual mechanism Williams has to prove, and he hasn't.
Marcus Vale: And nobody will defend the three-point-eight billion publicly. Ozanian reported it. Harbinger hasn't confirmed it. So the valuation the whole thesis rests on is an unconfirmed number against a stadium that doesn't exist yet.
Ben Okonkwo: Now add Shea Langeliers and Mark Leiter Jr. — both heading into season-ending surgeries right now, at the exact moment Cuban's fund is buying in. The on-field product is shaky.
Marcus Vale: Wait — both of them? At the same time?
Ben Okonkwo: Both. Season-ending. And Cuban has no operational lever — passive minority, limited governance rights, no disclosed exit path from a PE sports fund. If the product underperforms going into 2028, he can't call the clubhouse.
Marcus Vale: So the watch list is three things: does the stadium actually open in 2028, does Harbinger announce a second franchise deal — because that's what proves this is a real fund and not a Cuban vanity vehicle — and does Las Vegas actually sustain baseball attendance past opening weekend.
Ben Okonkwo: The second deal is the signal I'd weight most. One acquisition proves nothing about the thesis. A second one, different sport, different city, means Williams built something that works without Cuban as the anchor. That's when the valuation argument either holds or it doesn't.
Marcus Vale: But the thing is — even that second deal signal, I hit the same wall. Cuban ran the Mavericks hands-on for over two decades. Twenty-plus years of calling the shots. And now the best case is: the Las Vegas stadium opens in 2028, his fifty million appreciates, Harbinger has a proof-of-concept. That's the win. He still can't call the clubhouse.
Ben Okonkwo: Right — and the worst case is the stadium struggles, he holds an illiquid position with no operational lever to pull, and 'not my choice' stops being a quote and becomes, I don't know... a permanent condition.
Marcus Vale: That's actually the question I don't have an answer to. Is this him learning to live with it — or is this the waiting room before he finds somewhere he can own the majority again?
Ben Okonkwo: I don't know. I genuinely don't.
Marcus Vale: Neither do I. Which is — frankly, that's a weird place to end up after all of it.
Ben Okonkwo: Good conversation, though. Appreciate the thinking.
