Seattle NBA Expansion: BlackSun Private Equity and Tulalip Tribes Form Bid

An alternative investment group has emerged in the race to bring an NBA franchise back to Seattle, establishing a partnership with a regional Native American tribe to pursue a potential expansion team. According to reporting by The Athletic, BlackSun Private Equity has joined forces with the Tulalip Tribes to explore stadium development and ownership opportunities in the Pacific Northwest market.

The BlackSun Private Equity and Tulalip Tribes Partnership

The newly revealed coalition centers on a strategic agreement between BlackSun Private Equity and the Tulalip Tribes, whose reservation is located north of Seattle in Snohomish County. While the National Basketball Association has maintained a cautious stance regarding immediate expansion timetables, prospective ownership groups continue to position themselves for the league’s next wave of growth.

Seattle has been without a franchise since the SuperSonics relocated to Oklahoma City in 2008. Arena infrastructure in the city was substantially upgraded with the multi-million-dollar renovation of Climate Pledge Arena, which currently hosts the NHL’s Seattle Kraken and the WNBA’s Seattle Storm. However, an expansion franchise would require a dedicated ownership structure, substantial capital commitments, and formal league approval.

Evaluating the Seattle Expansion Landscape

The entry of the BlackSun and Tulalip Tribes coalition adds another dynamic to a market that has long attracted interest from prospective investors. Previous efforts have similarly sought to harness local tribal partnerships and private equity backing to demonstrate deep regional economic support for a returning franchise.

League officials, including Commissioner Adam Silver, have repeatedly acknowledged Seattle as a premier market for a future team, alongside other prospective cities such as Las Vegas. However, the NBA has consistently maintained that formal expansion discussions will not advance until the league finalizes its upcoming media rights agreements and addresses internal scheduling and structural priorities.

Next Steps for Prospective Ownership Groups

Prospective ownership entities, including the BlackSun and Tulalip Tribes partnership, face a lengthy vetting process dictated by the NBA Board of Governors. The league has not yet established an official application window or timeline for franchise expansion, leaving interested groups to build local infrastructure, secure land, and establish community partnerships in anticipation of a formal league announcement.
