EuroLeague expansion: The €4.3B gamble, and the NBA card

While everyone is looking at transfer windows and blockbuster contracts, a quiet meeting in Milan could change the entire map of European basketball. The shareholders' assembly of ECA (EuroLeague Commercial Assets) has taken place, hosted by Armani Olimpia Milan. There may have been no plays on the court, but the numbers discussed here are hotter than any scoreboard. According to La Gazzetta dello Sport, the main topic was not just expanding the league to 24 teams but also the emergence of a new beast: the NBA. The NBA Board of Governors has held discussions about buying a stake or partnering on investment in the EuroLeague. At the same time, 11 potential investors have submitted binding offers totaling up to €700 million to join the league. That's a shock for those used to seeing the EuroLeague as an open league, not a closed brand. I remember 2026, when I once rushed to believe a transfer rumor and paid the price. Since then, I never read any single-source story without checking a second source. With this news, my source still stops at La Gazzetta – a reputable sports paper, but there has been no official confirmation from ECA or the NBA. So let's put it in an ice water bath, wait for the fever to subside, and analyze. One thing is certain: The ECA assembly is not just a routine meeting. The presence of ECA CEO Chus Bueno and club-shareholder representatives indicates a larger strategy than simply increasing the number of teams. If the goal is to value the EuroLeague at €4.3 billion by 2027, with total expected investment over five years above €3.2 billion, then European basketball's owners clearly no longer see this as a fringe league. Look at the financial structure. €700 million from 11 applicants means an average of about €64 million per seat. But that's only the entry ticket. If the €4.3 billion valuation is achieved and split among 24 teams, each team could be worth more than €170 million. That's far ahead of the brand value of most current EuroLeague clubs, which still rely on sponsorship and broadcast revenue from fragmented national markets. This is the blind spot that most articles miss. People see €700 million and immediately think of a super-rich league. But to reach such growth, media and commercial revenues must skyrocket. Otherwise, investors will eventually realize they paid too much for a market still constrained by domestic calendars and an unstable model. This story is no different from a major transfer: there are buyers, sellers, and force majeure clauses. Contracts have hundreds of clauses, but the real value lies in cash flow. If the NBA truly gets involved, it could create a parallel path to the EuroLeague's independent plan, turning those €700 million offers into a bargaining weapon. ECA might tell the NBA: 'If you don't come, we still have 11 other investors.' That's a classic, effective tactic. On the sporting side, expanding to 24 teams would increase fixture density, forcing coaches to rotate deeper squads. But that's a matter for the future. For now, European basketball's decision-makers are playing a different game, not on the floor but at the negotiation table. And that game, I believe, will determine an entire generation of players. The lesson I've learned over many years in this craft: Hot news goes cold, but lessons are expensive. And the truth doesn't need breaking broadcast. We need one more source. Until ECA officially announces something, treat this story as a signal for market structure analysis, not a final verdict.
