The NBA just received a flood of billion-dollar interest for its European league project, and the league office is no longer speaking in hypotheticals. Momentum has turned into action. Because just hours after the March 31 bidding deadline passed, Mark Tatum stepped forward with a clear update on where things stand and what comes next.

Now, the news: the NBA has officially entered the review phase for its proposed European league after receiving massive interest from investors across the globe. Tatum confirmed the scale of that demand while outlining the league’s next step in narrowing down long-term partners.

And that’s what shifts this from concept to execution. “We have received significant interest from a range of prospective teams and investors for permanent franchise spots in a new league in Europe,” Tatum said via an official press release.

“The level of engagement and the scale of the bids reflect the marketplace’s belief in our proposed model and the enormous, untapped potential for European basketball. We will now review the bids in more detail and shortlist the partners who share our vision and commitment to accelerating the growth of the game across the continent.”

That statement lands with weight because of what just happened behind the scenes. More than 120 prospective investors submitted formal interest in the league, with multiple groups signaling willingness to invest at least $1 billion for permanent franchise spots. However, these submissions were non-binding declarations made under non-disclosure agreements, a standard step in large-scale sports expansion projects.

Meanwhile, the NBA structured these bids around a license model, with expected investments ranging between $500 million and $1 billion depending on market size and long-term value. Advisors including JPMorgan Chase and The Raine Group are now helping evaluate those submissions as the league begins its shortlisting process.

As a result, the timeline is no longer vague. The NBA is targeting an October 2027 launch for a 16-team competition built around 12 permanent franchises and four additional qualifying spots tied to FIBA pathways.

Adam Silver’s Vision Hinges on EuroLeague Partnership

For months, Adam Silver has made one thing clear: the preferred outcome is collaboration with Europe’s existing basketball structure, not a direct takeover. “I think for the betterment of European basketball, the best outcome would be if we came together with the EuroLeague here and that we came up with a systematic approach to growing the game throughout Europe,” Silver said at last month’s Board of Governors news conference in New York.

“That means complementing the country leagues, working together with the EuroLeague and working together with our federation, FIBA.” That context is critical to understanding the current moment. Because while Tatum’s statement focuses purely on investor interest and league formation, the broader picture involves ongoing discussions with the EuroLeague. A joint structure remains a real possibility, with recent reports pointing toward a potential expanded format if both sides align.

At the same time, those discussions come with pressure points. Existing EuroLeague clubs exploring entry into an NBA-backed league would still need to commit to full franchise license fees, which immediately raises the stakes financially and strategically. That creates a natural tension between partnership and leverage as both sides evaluate long-term control of European basketball.

Meanwhile, the NBA has already identified its priority markets. London stands out as a flagship destination due to its global media reach and strong investor backing. Paris brings in ties to Qatar Sports Investments along with a proven major-event infrastructure. Milan connects directly to RedBird Capital and its ownership of AC Milan, offering immediate credibility in one of Europe’s biggest sports economies.

Other major cities like Madrid, Barcelona, Berlin, Rome, and Manchester remain in contention, forming the backbone of a potential continent-wide league footprint.

What separates this moment from past international efforts is scale and intent. Unlike the National Football League, which expanded globally through scheduled games over nearly two decades, the NBA is attempting to establish permanent franchises across Europe from the start.

That approach changes everything. Because now the league must solve structural challenges immediately, including scheduling across continents, governance alignment with FIBA, and the integration or coexistence with EuroLeague systems.

At the same time, the upside remains massive. Franchise fees alone could generate billions, while creating a long-term pipeline for global fan growth and talent development. And that’s why Tatum’s statement carries real weight. This is no longer about whether the NBA will expand into Europe. That phase is already decided.

Now, it comes down to execution. Which investors make the cut, how the EuroLeague responds, and whether partnership or separation ultimately defines the future. Because over the next few months, as bids are reviewed and negotiations continue, one outcome will take shape. Adam Silver is not just expanding the NBA’s reach. He is positioning the league to reshape the structure of international basketball itself.
