The contract’s price has not been static. It has ranged from 8.5% to 60.0% over its trading history. The last day brought a move of -9.5 pts percentage points. Currently at 10.0%, the probability reflects a market that sees both outcomes as plausible. Resolution hinges on a formal test. The market settles as 'Yes' if, by Jan 1, 2027, a general tariff increase specifically on Canadian imports goes into effect. This means the start date set by legislation or executive order has passed without being paused or rescinded. Only tariffs that explicitly target Canada count; a new universal levy would not suffice. The general tariff rate must surpass the level that existed when the market launched, with item-specific exceptions disregarded. Resolution sources are official Trump administration announcements, supplemented by credible open-source consensus if needed. The hard deadline of Jan 1, 2027 is the central factor. Any concrete action—such as signed executive orders or the passage of a tariff start date—that meets the criteria could swing the price decisively. Equally, the absence of such action by the cutoff would settle the contract at zero. The price thus responds to the formal conditions alone, not to broader trade sentiment.
A general tariff increase on Canadian imports must go into effect—meaning its announced start date passes without being delayed or suspended—by the market’s deadline. The increase must be above the rate in place when the market launched and target Canada specifically.
No. The market requires the tariff to explicitly single out Canada. A broad new levy on all imports would not satisfy the condition, even if it raised the effective rate on Canadian goods.
A tariff only counts if it is actively in effect. An announcement alone, or a tariff that has been delayed or suspended before its start date, does not qualify. The market looks for the start date to have passed without interruption.
It is the base rate applied across all imports, ignoring item-specific exceptions. For example, compounding a new Canada-specific surcharge on top of an existing global baseline would produce the relevant rate. The market compares this rate to the one prevailing at creation.
