Holders should be aware of two key structural mechanics. First, the resolution deadline specifies September 30, 2026, but includes a 14-day extension clause if an ambiguous announcement occurs near the cutoff, allowing adjudication to extend into October 2026. Second, while official government announcements are the primary source, distinguishing between formal diplomatic agreements and unilateral policy shifts or preliminary negotiation frameworks requires interpretation. If the official statements leave room for doubt, resolution falls back on a consensus of credible news reporting and the totality of available information evaluated after the 14-day observation window.

Market explained before close
This market measures whether the United States and Canada announce a diplomatic agreement to lower US tariffs on Canada by September 30, 2026.
How it resolves
The market resolves to Yes if an official diplomatic agreement between the United States and Canada to lower, revoke, suspend, or cancel pending US tariffs on Canada is announced by September 30, 2026, at 11:59 PM ET. Both countries must issue clear declarative statements accepting the same qualifying agreement, either jointly or through separate announcements; references to ongoing negotiations or unconfirmed prospective deals do not qualify. The market resolves to No if no qualifying agreement is announced by the deadline. If an announcement occurs but its status is ambiguous, resolution may be delayed up to 14 calendar days after the last country's announcement to assess definitive confirmation or the totality of information. Resolution is determined by official information from the governments of the United States and Canada and a consensus of credible reporting.

Resolution rules at close
This market will resolve to “Yes” if a diplomatic agreement between the United States and Canada to lower US tariffs on Canada is announced by September 30, 2026, 11:59 PM ET. A diplomatic agreement to lower US tariffs on Canada refers to an official agreement, treaty, deal, or substantially similar diplomatic instrument that commits or obligates the United States to lower any tariffs on Canada, or includes the lowering of US tariffs on Canada as part of its stated terms. Any reduction, revocation, or suspension of US tariffs on Canada, or the canceled or suspended implementation of previously announced tariffs not yet effective, mutually announced as part of a diplomatic agreement, will qualify as lowering tariffs. All listed countries must announce their acceptance of the same qualifying diplomatic agreement. A joint announcement will qualify, as will separate announcements from each entity of its own acceptance of an agreement which, taken together, directly indicate that all the listed countries accepted the same agreement. Separate announcements of individual policies will not qualify if the policies are not announced as part of a diplomatic agreement. Each announcement must be a declarative statement that clearly and unambiguously communicates acceptance of an agreement. Statements that reference ongoing negotiations or a prospective agreement, or that allude to or express support for an agreement without confirming acceptance of the agreement, do not qualify. A qualifying announcement need not reference the agreement by name or use specific terminology, provided it clearly communicates acceptance of an agreement. Whether announcements from the listed countries represent a diplomatic agreement and whether such an agreement qualifies will be primarily determined through the announcements themselves. Where an announcement is made by all listed countries but, based on the announcements, it remains ambiguous whether the announcements represent a qualifying diplomatic agreement between the countries or whether the agreement qualifies, this market will remain open until either i) definitive confirmation that the announcements represent a qualifying diplomatic agreement between the listed entities is achieved through further announcements from the listed countries or a consensus of credible reporting or ii) 14 calendar days (ET) have passed after the date that the last country made their first potentially qualifying announcement. If this period would extend past the end date, this market will remain open to allow for 14 full calendar days to pass. If, at the end of the fourteenth calendar day, no definitive confirmation has been achieved, the announcements will be adjudicated based on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information. The resolution sources for this market will be official information from the governments of the United States and Canada and a consensus of credible reporting.
