Live prediction market odds for "Trump announces Canada tariff decrease by...?". December 31 leads at 64.5%. Next is October 31 at 15%. $6K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.
This market will resolve to "Yes" if Donald Trump, the White House, or any Cabinet member publicly and officially announces a tariff decrease on Canada between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". Any tariff decrease which is officially announced within the market's time frame will qualify, regardless of if/when the change goes into effect. The announced replacement of an existing tariff on Canada with a tariff of a lower rate will qualify, but the replacement of an existing tariff with a tariff of an equal or higher rate will not qualify. The announced removal of a relevant existing tariff will also qualify. A qualifying announcement must be made by Donald Trump, through an official White House publication or communication, or by a White House official authorized to speak on behalf of Donald Trump or the White House, including members of the Cabinet. A global/blanket tariff on all imports which does not specifically name Canada will not qualify. Announcements, notices, publications, or actions issued solely by federal departments or agencies, including U.S. Customs and Border Protection, the Department of Commerce, the Office of the United States Trade Representative, or the U.S. International Trade Commission, do not qualify on their own, unless they are announced by members of the Presidential Cabinet. This includes updates or amendments to the Harmonized Tariff Schedule, customs rulings, implementation guidance, changes to product coverage or exclusions, and antidumping or countervailing duty determinations. Such agency-level actions do not qualify merely because they implement or exercise authority delegated by Donald Trump or the White House. The relevant tariff change must itself be the subject of a qualifying announcement by Donald Trump or the White House within the market's time frame. A qualifying announcement must be a declarative statement of the U.S. government's present implementation of, previously-unannounced prior implementation of, or definitive decision to implement a tariff decrease against Canada. A qualifying announcement must clearly and unambiguously identify a relevant tariff decrease. Statements that merely allude to, reference, or describe such a change in tariffs, without clearly communicating it, do not qualify. A qualifying announcement must be made through official channels. Statements made incidentally or informally in a context not intended for official communication do not qualify. An announcement by Donald Trump, the White House, or the Cabinet that the United States accepts or agrees to an agreement, framework, or roadmap that includes a commitment to a tariff decrease qualifies only if (i) all parties whose acceptance is required for the agreement to take effect have accepted the agreement, or (ii) the announcement independently communicates a qualifying tariff decrease as a present and decided position of the United States, not contingent on acceptance by any other party. The following do not qualify as official announcements: Anonymous, unattributed, or leaked statements not confirmed by Donald Trump, the Cabinet, or the White House through a qualifying announcement; Statements by persons other than Donald Trump, the Cabinet, or White House officials authorized to speak on behalf of Donald Trump, the Cabinet, or the White House; Third-party speculation, analysis, or predictions that the United States will announce or implement such a policy; Satirical, fabricated, hacked, or impersonated communications; Statements that describe a prospective, contingent, probable, or conditional implementation of such a policy rather than announcing a present and decided position. Once a qualifying announcement is made, this market will resolve to "Yes" regardless of whether it is later reversed, or whether a tariff decrease is ever actually implemented. Resolution will be based on official information from Donald Trump, members of the Cabinet, or the White House.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
