EuroLeague Expands to 24 Teams: Phone Lines Open, Equity Locked

"The phone lines are open." Chus Bueno, a senior EuroLeague executive, said that in an interview published midweek. He was talking about the NBA, about the possibility of sitting down, about a marriage whose price both sides already know. It sounded like a man who has shut the door but is still keeping his foot in it.

On October 6, 2026, EuroLeague rejected a cooperation proposal from the NBA. The terms sit in a drawer, and Bueno confirmed they will stay there. Three weeks later, the phone lines were still open. Four weeks later, the league announced a plan to expand to 24 teams with up to eight new long-term licences, with the identities to be named in mid-November 2026.

Three items, all inside one quarter. Read separately, they are three press releases. Read together, they are a balance sheet — and every balance sheet has a fold in it.

Minimum fact table — compiled from Chus Bueno's remarks (EuroLeague) and the expansion plan announced in October–November 2026:

• Target: 24 teams; up to 8 new long-term licences; identities announced in mid-November 2026. • Share of licence holders that are financially self-sustaining: 40%; target of a majority within 5 years. • Ownership structure: 13 shareholder clubs; 10-year franchise agreements. • Equity: more than 80 million euros per position, forfeited in full on exit. • Potential competitor: NBA Europe, launching in 2027. • The NBA proposal was rejected on October 6, 2026; its terms remain undisclosed.

I have followed EuroLeague for more than a decade, mostly through Final Four nights and summer payroll reports. Based on my experience tracking these games, this league has never announced a figure without attaching a condition. This time the condition sits elsewhere: the question is no longer who gets in, but who pays for the seat, and with what kind of right.

The line is open, the door is bolted

EuroLeague runs like a miniature shareholders' corporation. Thirteen clubs hold the power, signed to ten-year franchise agreements, with each equity position marked above 80 million euros and forfeited entirely if a club walks. Beyond the lost equity, an exiting club faces contractual penalties, potential damages claims from the remaining clubs, and a re-entry price set by the league itself at the moment of return. Four layers of cost, none of them published with a number attached.

The internal financial picture is not flat either. Only 40 percent of licence holders balance their own books; the rest live on owner subsidy. If the denominator is the 13 shareholders, that is roughly five clubs — meaning eight clubs are spending somebody else's money to play elite basketball. The goal of a "sustainable majority within five years" is therefore a financial target, not a sporting one.

Outside, the NBA Europe project is scheduled for 2027. Bueno himself has warned about fragmentation: two leagues fighting for the same slot, the same broadcaster, the same viewer wallet. To someone who reads balance sheets for a living, that warning sounds like a confession about position.

The 46-round problem

Expanding to 24 teams sounds like good news. On the calendar, it is an awkward arithmetic problem. A double round-robin at 24 teams produces 46 rounds; against an 18-team baseline, the equivalent is 34 rounds. A gap of roughly one third of the fixtures. A single round-robin drops to 23 rounds, which shrinks the inventory sold to broadcasters — the opposite of why you expand.

So 24 teams forces a format redesign: conferences, a play-in, or asymmetric scheduling. Each option carries a competitive-integrity cost, in a league already criticised for licence-based entry. The core insight sits here: expansion is a commercial fix dressed as sporting news, but its real binding constraint is the calendar — more games means more revenue, and more games also means colliding with domestic leagues and FIBA national-team windows.

At the labour-market level, 24 teams means roughly 30 to 35 percent more roster slots at the elite European tier. The mechanics are simple: supply of slots rises, and the marginal price of a competent rotation player rises with it. The real threat NBA Europe poses is not taking the stars — those left for America long ago — but draining the mid-tier wage band, the segment where European clubs historically held a cost advantage. And at 46 rounds, the load lands on exactly the players who must also play for national teams, dragging soft-tissue injury risk and load-management pressure from the players' union behind it.

Four layers of cost for one walkout

Contracts have exit clauses; cash flow does not. The 80-million-euro equity mark serves a dual function: it is a paper asset and it is a fence. If all 13 clubs hold that valuation, the collective internal mark lands around one billion euros or more. I have to be explicit: that is an inference from one ambiguous sentence, unverified, and an internal mark is not a realised transaction price. Data series do not lie, but the people arranging them do.

Ten-year franchises, plus contractual penalties, plus forfeited equity form a deliberate poison pill. Its primary function is anti-defection. And it exists because the NBA threat is real, not because the clubs are spontaneously loyal.

The most expensive undisclosed term

Across the whole plan, the one unanswered question is whether the eight new licences come with equity. Two scenarios, two opposite outcomes.

If the new seats carry no equity, EuroLeague becomes a two-tier structure: the 13 shareholders keep control, the newcomers sign long-term deals and pay for a place inside the ecosystem. Power intact, media inventory up, and the 40 percent target finally has a funding source.

If the new seats do carry equity, the 13 incumbents are diluted, and the 80-million mark loses its footing — because it was priced on a closed circle of thirteen. When the door opens to newcomers, the incumbents' value has to be re-marked. That is why I expect the mid-November list to arrive with a term sheet attached, not just a list of names.

The blind spot in the official story

The official story is tidy: the league grows, the door opens, the dialogue continues. The blind spot is that an open phone line is leverage, not reconciliation. Every call from the NBA raises the value of staying in EuroLeague — provided those staying believe leaving would cost more. The 80-million figure was published to do exactly that, aimed at clubs quietly taking meetings with American partners.

There is a more serious blind spot. The two things the NBA cannot replicate in Europe are qualification earned through domestic-league merit and a single-site Final Four. If EuroLeague pushes its calendar to 46 rounds, colliding with domestic leagues and FIBA windows, it erodes precisely those two shields in order to chase more inventory. The concrete mechanism behind Bueno's "loss of value" sits at the broadcaster: an NBA Europe schedule that dodges EuroLeague midweek slots forces European networks into a two-subscription model. Two subscriptions, one viewer wallet. A product that loses its differentiation has to compete on capital — and on that field, the opponent comes from New York.

After every deal, there is a shadow somebody tries to hide in the cost sheet. Here the shadow is the denominator behind the 40 percent: 40 percent of thirteen, of twenty, or of twenty-four? Three denominators, three very different degrees of difficulty, and only one of them makes the five-year target feasible.

The next domino

I do not predict the future; I only read the balance sheet ahead of time. Three variables will surface in mid-November 2026: the entry fee, the equity rights, and the competition format for the 24-team season. If a shareholder club leaves within the next 18 months, the 80-million mark turns from a deterrent into a precedent — and every ten-year franchise agreement in the European basketball market will need re-pricing. If nobody leaves, expansion is simply the only way to keep the phone lines open without anyone having to pick up.
