A new contender has entered Seattle's race to bring back the SuperSonics, and it comes with a twist nobody saw coming: an arena built not in the city, but 30 miles north on Tulalip Tribes land near Marysville. BlackSun Private Equity says it can assemble $8.1 billion for the expansion franchise, with the tribe providing the site through a partnership the company describes as central to its pitch.
BlackSun's arrival, first reported by The Seattle Times, makes it the second publicly known Seattle bidder alongside One Roof Sports and Entertainment, the group that already operates Climate Pledge Arena and owns the Kraken under a public-private partnership, according to the same report. One Roof remains the front-runner in talks about a potential Sonics return, per the Times, but BlackSun's entry adds a genuinely different model to the mix — one built around tribal land, tribal revenue-sharing, and a suburban arena rather than a downtown one.
BlackSun's chief global strategy and communications officer, Nick Rathod, told the paper that the bid is being built differently from the beginning. Rathod previously worked in the administration of President Barack Obama, the Times reports, and the firm is led by CEO Atonn Muhammad, who played walk-on football at the University of Miami in the early 1990s.
How the Tulalip Arena Plan Would Actually Work
The plan calls for the team to initially play as a tenant at Climate Pledge Arena — the $1.15 billion, privately funded downtown venue that reopened in October 2021 with seating for 18,300 basketball fans — while BlackSun builds its permanent complex on tribal-owned land near Marysville, per the Times. The Tulalip Tribes have confirmed discussions with BlackSun and, according to the Times, the two sides are in the final stages of a partnership agreement. BlackSun has also announced Native World Sports as a partner, a group that says its goal is advancing tribal participation in professional sports and entertainment.
The Tulalip reservation already hosts one of the region's largest sovereign commercial developments. Quil Ceda Village, chartered in 2001, was the first consolidated borough established on tribal trust land anywhere in the United States and spans 495 acres, according to a Wikipedia entry on the village that notes it already hosts the Tulalip Resort Casino and Seattle Premium Outlets. BlackSun says it wants tribal nations to serve not just as landowners but as leaders and potential team owners, aiming to make the Sonics an economic and cultural engine for the whole region — a franchise, the company says, that belongs to the entire Pacific Northwest.
The Commute Problem Nobody Can Ignore
The elephant in the room is I-5. Seattle-to-Everett commutes take an hour or more during peak travel times, per the Times report, and separate local reporting from AMP Properties Group NW pegs the 33-mile corridor between downtown Seattle and the Tulalip reservation at 60 to 90 minutes or longer during weekday rush hour and major events. That is a tough sell against a franchise culture that, per the Times, generally prefers downtown locations — the Sacramento Kings and Detroit Pistons both moved from suburban sites into downtown arenas, while the Golden State Warriors relocated from Oakland to San Francisco. The Times also notes exceptions: the Los Angeles Clippers built Intuit Dome 11 miles from downtown in Inglewood, and Dallas is reportedly seeking to build its own venue outside the city core.
NBA ownership rules add another layer of difficulty. League requirements mandate a single controlling owner holding at least 15 percent of a franchise, the Times reports, while a private equity fund like BlackSun's can hold up to 30 percent of the investment under NBA rules — a ceiling separately confirmed in Front Office Sports reporting on league bylaws, which also notes no single fund can exceed 20 percent on its own. NBA rules also cap the number of individual investors in an ownership group at 25, according to the Times.
Building the War Chest and the Résumé
BlackSun says the $8.1 billion figure would be assembled through a consortium including high-net-worth individuals and other investors, and the company expects to add more backers, including some with local ties, before the process advances. The firm's financial muscle traces back to its Mega Fund I, which secured $1 billion in capital in August 2026 toward a $7 billion target, according to Pulse 2.0, which reported that Dubai-based Greenstone Equity Partners was appointed as placement agent to raise capital from Middle Eastern sovereign and institutional investors.
This is not BlackSun's first swing at NBA ownership. Muhammad told the Times the firm participated in discussions around the sale of the Boston Celtics roughly two years earlier, and Pulse 2.0 reported that BlackSun made a $6 billion offer for the Celtics in 2024 before losing out to a rival $6.1 billion purchase group. The company's advisory board leans on star power too — Dallas Mavericks head coach Jason Kidd, Pro Football Hall of Famer Lawrence Taylor, and boxing champion Roy Jones Jr. are all listed among its high-profile executive and advisory figures, per reporting from The Washington Post.
Why Seattle, and Why Now
BlackSun says it chose Seattle over Las Vegas as the stronger strategic market for its bid, framing the effort as an attempt to bring the Sonics home nearly two decades after the team moved to Oklahoma City following the 2008 season. Whichever group wins, the winning bidder automatically reclaims the Sonics name, logos and green-and-gold trade dress at no cost under Section 6 of the 2008 settlement between the city and the team's former ownership — a provision Hoodline detailed earlier this year alongside the roughly $7 billion to $10 billion expansion fee range now under discussion.
The NBA has not commented on either the Seattle or Las Vegas ownership proposals specifically, according to the Times, and league officials expect a decision on expansion to Seattle, Las Vegas or both before the end of 2026. The NBA Board of Governors is set to meet again in New York this month for further expansion talks, with Commissioner Adam Silver expected to provide another update on the process. BlackSun says it plans to engage elected officials, community leaders and fans before any major decisions move forward.
