All three editorial cases
Central is open by default. Cautious and optimistic remain available as server-rendered details, including the assumptions that produce both endpoints of the displayed range.
Formal exploration, a functioning Seattle arena and visible prospective ownership create a credible path, but expansion, Seattle selection, admission terms and launch timing all remain unresolved. This case gives substantial weight to two-team expansion while retaining meaningful no-expansion, one-slot, staggered-award and delay risk.

Season-opening policy
Each lag estimates readiness after an award. The first-game planning date then moves to the next October 15 opening on or after readiness; a 21-month readiness interval does not imply a game exactly 21 months after the award.
Award-date distribution
Readiness-lag distribution
Exploration fails, narrows to one slot, or moves too slowly often enough that Seattle's pre-2030 path becomes a low-probability tail. This case treats preliminary bid activity and local arena readiness as helpful but insufficient against Board, market-selection, award-timing and post-award execution risk.

Award-date distribution
Readiness-lag distribution
The Board completes a two-team process, Seattle's venue and ownership preparation prove decisive, and the award arrives early enough for a planned season opening before 2030. The case remains below certainty because exploration can still fail and every public source stops short of an award or launch commitment.

This Date in the NBA: January
NBA.com's historical record identifies January 10, 2003 as the final Board award of Charlotte's expansion franchise, distinct from the December 2002 recommendation.
What this does not prove: A single historical award under a different league, media, arena, labor and ownership environment is context only and is not a trained timing calibration.
Date precision: date. Time zone: not listed.
Bobcats Build Inaugural Roster With 19 Picks In Expansion Selection
Charlotte's NBA-operated site records the June 22, 2004 expansion selection that built the inaugural Bobcats roster.
What this does not prove: Historical roster construction shows that draft rules are downstream implementation work; it does not establish current Seattle or Las Vegas rules or timing.
Date precision: instant. Time zone: EDT.
Washington Wizards vs. Charlotte Bobcats game summary
NBA.com's game record identifies Charlotte's November 4, 2004 regular-season opener, 664 days after the January 10, 2003 final Board award rather than the earlier December 2002 recommendation.
What this does not prove: The 664-day interval is one historical example, not a representative sample or evidence that a modern Seattle award would follow the same delivery path.
Date precision: event date. Time zone: not listed.
Frequently Asked Questions and Fast Facts
At retrieval, the arena operator said the building opened in 2021, listed basketball capacity at 18,300, and described it as designed for future NBA basketball and compliant with NBA standards.
What this does not prove: This is an operator assertion, not an NBA inspection, tenant approval, executed team lease, practice-facility plan or league certification.

NBA Board of Governors approves exploration of expansion to Las Vegas and Seattle
The NBA Board authorized formal exploration of potential expansion to Seattle and Las Vegas and retained PJT Partners to evaluate markets, ownership groups, arena infrastructure and economics.
What this does not prove: Authorization to explore is not authorization to expand, does not specify a slot count, and does not award Seattle a franchise.
Date precision: date. Time zone: not listed.
Adam Silver addresses NBA expansion, Kawhi Leonard investigation and more
NBA.com reported Silver's July 14 media remarks that no expansion votes had been taken, discussions remained, prospective groups were pitching plans, and owners still sought a decision by year-end.
What this does not prove: The direct no-vote statement is a July status point, not evidence of unchanged status through September or proof that the year-end objective will be met.

NBA commissioner Adam Silver on league's plan to explore expansion in Seattle and Las Vegas
NBA.com reported Silver saying zero, one or two markets remained possible and that the league hoped to be ready to move ahead by the end of 2026; the article called 2028-29 a speculated inaugural season.
What this does not prove: The end-2026 objective is not binding, zero expansion remained explicit, and the article itself distinguished 2028-29 speculation from a confirmed launch season.
Date precision: displayed time timezone unknown. Time zone: not listed.
NBA announces schedule for 2026-27 season
The NBA's official August 13 release published the 2026-27 regular-season schedule for the existing league and did not establish a Seattle inaugural season.
What this does not prove: A 2026-27 schedule cannot rule out a later Seattle launch and is only a bounded check against claiming a current schedule slot.
Date precision: displayed time timezone unknown. Time zone: not listed.
One Roof Sports and Entertainment Announces Investor Update
One Roof identified Samantha Holloway as majority owner and managing partner, named additional investors, stated it would pursue a Seattle NBA team if expansion proceeds, and announced control of Climate Pledge Arena.
What this does not prove: This first-party ownership statement does not establish an NBA-accepted bid, preferred bidder, committed expansion-fee financing or Board approval.
Date precision: date. Time zone: not listed.
Memorandum of Understanding with Oak View Group
Seattle's arena framework contemplated a future NBA tenant, a Seattle-domiciled team lease and nonrelocation terms, while expecting NBA practice and administration facilities to be off-site.
What this does not prove: The framework is not an executed lease for a selected Seattle NBA franchise and leaves practice, headquarters and league approval work unresolved.
Date precision: month. Time zone: not listed.
Resolution 32198
Seattle Resolution 32198 declared the city's readiness for an NBA team and declared Climate Pledge Arena ready for an NBA team.
What this does not prove: The resolution records municipal policy and readiness claims; it is not an NBA venue inspection, franchise award, tenant lease or operating signoff.
Date precision: year. Time zone: not listed.
Second bidder steps up for Seattle expansion team, wants to build new arena outside city
NBC Sports, citing The Athletic, reported two prospective Seattle groups had made preliminary bids and described a second group's Marysville arena concept; the NBA had not publicly confirmed a Seattle award.

Professional Basketball Club, LLC and City of Seattle Settlement Agreement
The 2008 settlement contains a conditional post-NBA-approval path for specified Seattle basketball intellectual property to transfer to a new Seattle owner on request and subject to NBA rules and approval.
What this does not prove: The agreement is conditional and does not itself establish whether any later assignment or license has been executed; the separate history-sharing provision was tied to an expansion approval within five years.
Date precision: date. Time zone: not listed.
This Date in the NBA: November
NBA.com's historical record says Toronto received a franchise on November 4, 1993 and the Canadian expansion teams debuted in November 1995, roughly a two-year award-to-launch interval.
What this does not prove: Toronto's roughly 729-day interval comes from a different two-country expansion and is context only, not a probability calibration for Seattle.
