Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. 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 216 days ago. Ages are as of when this page was built.

About this market

Final prediction market prices for "Trump approval Up or Down this week?". Yes last traded at 0.1%. $60K has traded across 1 outcome on Polymarket. The market closed on Mar 21, 2026.

This market will resolve to "Up" if Donald Trump's Silver Bulletin approval rating is higher on March 20, 2026, than on March 13, 2026. This market will resolve to "Down" if Donald Trump's Silver Bulletin approval rating is higher on March 13, 2026, than on March 20, 2026. This market will resolve to 50-50 if Donald Trump's Silver Bulletin approval rating is the same on each date. The data point for the second reference date will only be considered once a subsequent day’s data point has been published, thereby finalizing the value for the second date. If no data point is published for the first reference date, the most recent prior day with a published data point will be used instead. If no data point is published for the second reference date by 12:00 PM ET on the third calendar day after that date, the most recent prior day with a published data point will be used instead. This market's resolution source will be Silver Bulletin's approval rating poll aggregator, https://www.natesilver.net/p/trump-approval-ratings-nate-silver-bulletin, specifically the approval rating indicated by the green trend line for the resolution date. Changes in the methodology by which Silver Bulletin calculates the approval rating will have no bearing on the resolution of this market. If Silver Bulletin's approval rating becomes permanently unavailable, RealClearPolitics will be used. The resolution source reports the rating value to only one decimal point (e.g., 42.8%, 33.9%, etc). Thus, this is the level of precision that will be used when resolving the market.

Questions

What does the consensus price mean?

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%.

How is the payout worked out?

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.

Why do the venues show different prices?

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.

Is a price gap an arbitrage?

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.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
