Three weeks before the first regular-season game, the useful checks are narrow: confirm the schedule is final, confirm which Kalshi contracts are actually open, and read the settlement rules before committing capital. This guide covers both sides of the 2026-27 NBA tipoff week, pairing the league's official key dates with a Kalshi market snapshot captured September 29, 2026, the same day training camps opened.
Primary sources checked: the official NBA key dates page (updated September 26, 2026), the 2026-27 schedule announcement, the Kalshi market rules and market outcomes pages, and the CFTC filing on Kalshi's regulated exchange status. Everything below reflects that snapshot date, and availability can change after it.
The NBA's key-dates page is the controlling calendar source, and its October 20 start matches the schedule announcement verified in August, so the date is settled on both official pages. The broader season-start overview lives in the earlier season-start market checks; this page is the final countdown checklist. The run-up to tipoff looks like this:
The confirmed slate, all on NBC/Peacock per the official key-dates page:
Final roster cuts land the day before tipoff, so injury news and rotation decisions can break quickly in the 24 hours after the Oct. 19 deadline. Traders with season-long positions should treat opening-night results as one game out of 82, not as a signal about how a champion market settles.
Entering the 2026-27 NBA tipoff week, the KXNBA series showed exactly one open event at snapshot: KXNBA-27, "2027 Pro Basketball Champion", with 30 team markets (KXNBA-27-ATL, KXNBA-27-BOS, and one ticker per franchise). Settlement language follows a single template with the team name swapped in. Rules verbatim, using the Atlanta placeholder: "If Atlanta wins the 2027 Pro Basketball Finals, then the market resolves to Yes."
Four related events were also open, with no market counts pulled this run:
Cup markets get a full treatment in the Emirates NBA Cup schedule and market checks, and the team-by-team champion breakdown sits in the 2027 champion futures guide. This page is static by design: it carries no prices, volumes, or implied probabilities, and current availability must come from Kalshi directly.
Every one of the 30 champion markets lists a close_time of 2029-07-30T14:00:00Z with can_close_early set to true. The close_time field is a trading deadline only. It is not a championship date and not a settlement date. Resolution follows the rules text quoted above, meaning the 2027 Pro Basketball Finals outcome, and markets can close well before any deadline field. One observed detail: the list view showed no mutually_exclusive field for KXNBA-27, so treat that as an API observation rather than a rule claim.
One gap matters for timing analysis: the NBA has not announced 2027 playoff or Finals dates. Any assumption about when a champion market resolves should come from the Kalshi rules text, not from an imagined postseason calendar.

Tuesday, October 20, 2026, per the NBA's official key-dates page, updated September 26, 2026. The start matches the schedule announced in August, so the calendar is final on that point. Rosters are set the day before, October 19 at 5 p.m. ET, and training camps opened September 29, the same day this guide's Kalshi snapshot was captured.
Three games are scheduled, all on NBC/Peacock: Boston Celtics vs. Detroit Pistons at 3 p.m. ET, Philadelphia 76ers vs. New York Knicks at 7 p.m. ET, and Oklahoma City Thunder vs. San Antonio Spurs at 9:30 p.m. ET. Times come from the official NBA key-dates page, which is the source to recheck for any late changes to the slate.
In the September 29, 2026 snapshot, the KXNBA series had one open event, KXNBA-27 "2027 Pro Basketball Champion", with 30 team markets. Also open: KXNBAMVP-27 for MVP, KXNBACUP-26 for the Cup champion, and two Cup qualifier events. Availability changes, so verify current listings and rules on Kalshi before trading.
No. The 2029-07-30 close_time on all 30 team markets is a trading deadline field, not a settlement date, and each market can close early. The rules resolve on the 2027 Pro Basketball Finals outcome, phrased as "If [team] wins the 2027 Pro Basketball Finals, then the market resolves to Yes." Read the live rules text before relying on any date.
