🥇 Tier 1: The Dominant Leader

• December 31 (66%): Currently commanding the highest probability, December 31 is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 66¢, signaling a high degree of market conviction. This contract alone has generated $43.7K in volume.

🥈 Tier 2: The Primary Challengers

• November 30 (38%): Positioned as the most viable alternative, November 30 maintains a 38% chance of resolving true. Its “Buy Yes” shares currently trade at 38¢.
• October 31 (6.7%): Sitting in third place with a 6.7% probability, the market shows measured skepticism toward October 31, treating it as an outside wildcard unless momentum shifts.

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 August 31, 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 cancelled 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.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome December 31 currently trades at 66%, but our AI places its Fair Value at just 52.6%. This creates a large negative EV Gap of -13.4%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies October 31 as the premium value opportunity on the board. While the market only assigns it a 6.7% trading probability, our AI’s Fair Value assessment sits at 14.8% — yielding an impressive +8.1% EV Gap.
