The NBA wants to export American game-night polish to Europe. The problem, the league told investors this week, is that some European arenas are not set up to receive it.

At Sportico’s Invest New York conference on Tuesday, deputy commissioner Mark Tatum named crowd atmosphere as a specific concern as the league moves toward launching NBA Europe in October 2027, according to Eurohoops.

“In some of those games, you wouldn’t feel comfortable bringing your family,” Tatum told the conference. “We want to replicate the NBA experience over there while maintaining the culture and the sporting culture and the passion that they have.”

European basketball’s loudest halls, from Belgrade to Athens to Istanbul, are part of the sport’s identity on the continent. Softening them for a US-style broadcast product is one of the cultural fault lines of the project.

Tatum’s 16-team blueprint

The structure Tatum sketched out is a 16-team league with 12 permanent franchises sold to investors and four spots reserved for clubs that qualify through sporting merit. Franchise entry fees have been reported as high as $1 billion.

A list of target cities circulated by The Sports Encounter in October included London, Manchester, Paris, Lyon, Madrid, Barcelona, Milan, Rome, Berlin, Munich, Athens, and Istanbul. The map pointedly puts flags in the UK and France, two markets where top-flight European basketball has no real incumbent.

Tatum has previously said the project is “in the final stages” ahead of launch, with bids going through the NBA Board and FIBA, he said at an investor update in June.

The EuroLeague question

Pressed on why European clubs would switch allegiance, Tatum reached for a football comparison, arguing that the current system behaves like a closed league and that European clubs want the kind of open-competition dream embodied by football’s Champions League.

The target of that line is the EuroLeague, basketball’s current elite club competition, which operates on a licensing model that guarantees selected clubs a place each season. Tatum said the arrangement has left those clubs pouring tens of millions of dollars into teams whose underlying franchise values do not grow, and that they are looking for a new economic partner.

Negotiations with the EuroLeague have continued in parallel. Tatum has said the NBA is “prepared to proceed regardless” if no agreement is reached, he told Yahoo Sports in late October.

No founding clubs confirmed

Despite a year of signaling, no specific founding franchises have been announced. Tatum has repeatedly said there is no timeline for that reveal. Ownership groups publicly linked to the project include Luka Doncic’s BC Roma venture and Tony Parker’s ASVEL.

Infrastructure is a second pillar of the pitch to investors. New or upgraded arenas, Tatum argued, would host 30 to 40 home basketball nights per club and spend the rest of the year on concerts, conferences, and other events.

The next concrete milestone is the formal naming of founding clubs, which Tatum has said will come at some point before the October 2027 tip-off.
