Seattle’s NBA expansion conversation now has two distinct arena paths attached to the two publicly known ownership proposals.
One Roof Sports and Entertainment, led by Samantha Holloway, has a relationship with Climate Pledge Arena, the existing Seattle Center building that already hosts the Kraken and Storm. BlackSun Private Equity has publicly described a different path: an arena and entertainment district near Marysville in partnership with the Tulalip Tribes, if the NBA awards BlackSun a franchise.
Neither venue path has received NBA approval. The league has not announced an expansion award, a winning Seattle ownership group or a final arena requirement for a future team.
Climate Pledge Arena: the ready-now case
The One Roof case begins with an operating building near downtown Seattle. That matters because a franchise award would require a credible plan for opening night, premium inventory, event operations and local accessibility—not only a long-term rendering.
Samantha Holloway has said that an NBA team could be additive if it is structured correctly. Her group’s connection to the arena creates the most developed venue story in the publicly known Seattle field.
It also leaves a practical question for any rival bidder: whether it would become a tenant at Climate Pledge Arena or build an alternative.
Marysville: the proposed destination model
BlackSun’s concept offers a different proposition. Nick Rathod told The Athletic that the group wants to pair a proposed arena with an entertainment district and a mobility plan for fans traveling to the site north of Seattle.
That vision could create a regional destination, but it also has a more demanding development path. The arena would be a future project, and the group would need to demonstrate transportation, financing, fan access and construction feasibility before it could become a realistic NBA home.
The public reporting has been clear about the distance: the proposed Marysville site is roughly 35 miles from Seattle. That does not make it impossible. It does mean the ease of the fan journey will be one of the plan’s defining tests.
What the NBA is actually evaluating
Arena location is only one part of a bid. The league is also reviewing investor groups, ownership structure and price indications. The reported PJT Partners process is designed to collect exactly that kind of information.
For fans, the key is to separate a plausible plan from a completed outcome. The NBA has not told Seattle it will get a team, and it has not selected a venue. But the emergence of two identifiable arena approaches means the next phase of the Seattle SuperSonics discussion can focus on real tradeoffs: immediate readiness, regional access, ownership depth and the long-term experience a new team would create for Seattle basketball.
