Next is June 30, 2027 at 16%. The venues list this event, but none of their outcomes are matched yet, so prices are shown separately.
Consensus blends each venue’s last price, weighted by how much has traded there. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 7 min ago. Ages are as of when this page was built.

Live prediction market odds for "Canada becomes EU Associate Member by...?". December 31, 2027 leads at 23.5%. Next is June 30, 2027 at 16%. $13K has traded across 4 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 1, 2027.
This market will resolve to "Yes" if Canada and the European Union sign or formally adopt a written diplomatic instrument that establishes an associate membership or equivalent status for Canada in relation to the European Union by the specified date, 11:59 PM ET. Otherwise, it will resolve to "No". An instrument establishes an associate membership or equivalent status if it is described in its own text as establishing associate membership, associate member status, or an equivalent formulation. Proposals, invitations, statements of intent, negotiations, or action by only one side do not qualify. Existing or sector-specific trade, defence, research, or mobility arrangements alone do not qualify. Unless the written instrument is formally adopted without signature as described below, the instrument must be signed by both Canada and the European Union (either as an institution or as a composite of its member states). Both parties must either sign the same document or sign individual documents that substantively and directly indicate acceptance of the same underlying instrument, regardless of minor formatting, wording, or translation differences between the signed versions. Both physical signatures and officially-issued electronic signatures will qualify as signatures. If the written instrument is recognized by Canada and the European Union as not requiring signature for execution, formal adoption of the instrument by both parties without signature will qualify. Formal adoption may be established by official actions, including: (i) an official joint statement announcing that Canada and the European Union have adopted, approved, executed, concluded, or otherwise finalized the instrument; (ii) mutual official confirmation that the same published instrument has been agreed to, adopted, approved, executed, or concluded by both parties; (iii) adoption, approval, or endorsement through an official resolution, ministerial decision, executive decision, or equivalent institutional act, where that act is the mechanism by which the relevant party adopts the instrument; or (iv) an exchange of official diplomatic notes or letters confirming acceptance of the same instrument. Whether an instrument qualifies will be primarily determined by its officially released text. A qualifying instrument must be signed or formally adopted by both Canada and the European Union by the specified date, 11:59 PM ET. If such an instrument is signed or formally adopted by that time, but the complete text has not been released within 28 days of adoption, official and definitive announcements from Canada and the European Union regarding the text, or a consensus of major news agencies of record, may be used to determine whether the instrument qualifies. If, on the specified date, the text of such an instrument has not been released and genuine material ambiguity remains as to whether it satisfies this market's requirements, settlement may be postponed to allow for 28 calendar days after the date of adoption to pass pending release of the text. Once a diplomatic instrument has been signed or formally adopted without signature by both Canada and the European Union and confirmed to satisfy the requirements of a qualifying written diplomatic instrument, this market's condition is met, regardless of whether the instrument later enters into force, is ratified, receives legislative or treaty consent, or is subsequently repudiated, withdrawn from, or not implemented by Canada or the European Union. The primary resolution sources for this market will be official information from Canada and the European Union and the officially released text of an instrument; however, a consensus of credible reporting may also be used.
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.
