A useful sports-contract check starts with the official schedule, then matches that event to the exact contract ticker and rules. Traders should not infer a deadline, settlement outcome, or probability from kickoff time alone. Current prices and availability must be checked directly on Kalshi.
Update, September 10, 2026: the opener is complete. The Seattle Seahawks beat the New England Patriots 13-10 on Wednesday, September 9, 2026, in the season-opening game that kicked off at 8:20 p.m. ET on NBC and Peacock. This page documents the pre-game contract checks alongside the verified result and the finalized Kalshi settlement status.
Primary sources checked: the official NFL Week 1 schedule, the NFL kickoff announcement, the dated Kalshi opener event, the CFTC filing for Kalshi, and the ESPN final scoreboard entry used for the September 10 result recheck.
The live NFL schedule identifies New England as the visitor and Seattle as the host. Seattle was identified in the earlier league announcement as the defending Super Bowl LX champion and kickoff host. That announcement preceded the opponent reveal, so the live Week 1 schedule controls the matchup.
The league can change scheduling details. Readers should recheck the official NFL schedule rather than treating this static page as a permanent schedule feed. The broader season calendar is covered separately in the 2026 NFL season start and kickoff guide.
The official schedule contained 16 Week 1 games when checked on September 2. Times below are ET and should be verified against the live NFL page before making a contract decision.
The NFL Football Operations calendar lists Kickoff Weekend as September 9, 10, 13, and 14. It also separately identifies the September 10 game at Melbourne Cricket Ground.
Kalshi's public API showed 32 open events across the first two weeks in the KXNFLGAME series. Filtering that dated response to September 9, 10, 13, and 14 produced 16 Week 1 events with 32 active nested market objects, two for each game.
This was a point-in-time result from September 2, 2026. It does not establish current availability, liquidity, prices, reader eligibility, or future contract status. Those details must come from Kalshi directly.
For the Patriots-Seahawks opener, the exact event contained two active team-outcome markets at the snapshot:
These are team-specific outcome contracts, not one generic NFL market. The primary rules in the dated response state that each side resolves Yes only if its named team wins the professional football game originally scheduled for September 9, 2026.
The secondary rules also addressed a tie and whether a postponed game begins within 48 hours. Traders should read the exact live event rules because this guide does not infer settlement, expiration, or trading deadlines from those provisions. Kickoff time is not automatically the contract close time.
Recheck on September 10, 2026: the two opener markets are no longer active. Kalshi's public API shows KXNFLGAME-26SEP09NESEA-SEA finalized with result Yes and KXNFLGAME-26SEP09NESEA-NE finalized with result No, with a recorded close time of 2026-09-10T03:28:38Z, which is 11:28 p.m. ET on September 9, after the game had started. This recheck records settlement status only. It makes no claim about prices, volumes, payouts, or any other Week 1 market.
The CFTC filing page listed KalshiEX with status “Designated” when checked on September 2, 2026. That regulatory listing does not approve a particular sports contract, establish availability for a reader, or validate a trading decision.

The game kicked off Wednesday, September 9, 2026, at 8:20 p.m. ET. The September 10, 2026 recheck shows the final score: Seahawks 13, Patriots 10, per ESPN's final scoreboard. Readers should confirm scores and remaining Week 1 details on the live NFL schedule.
As of September 2, 2026, the event ticker was KXNFLGAME-26SEP09NESEA with nested market tickers KXNFLGAME-26SEP09NESEA-SEA and KXNFLGAME-26SEP09NESEA-NE. The September 10, 2026 recheck shows both markets finalized: Seattle Yes, New England No. Dated API status does not describe any other event or market.
The September 2 event snapshot contained secondary rules addressing a tie, a postponement that starts within 48 hours, and a game that does not start within that window. This summary is not a substitute for the operative text. Traders should read the current event rules and should not infer close or settlement timing from kickoff.
No. The September 2, 2026 API snapshot only recorded the contract status returned at that moment. It does not establish later availability or access for a particular reader or jurisdiction. Check Kalshi directly for current status, account eligibility, exact rules, and fees before placing an order.
