What the markets expect

Autism 99%

Next is Predict / Prediction at 99%. The venues list this event, but none of their outcomes are matched yet, so prices are shown separately.

Odds by venue

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 1 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "Trump approval rating on October 30?". Autism leads at 99%. Next is Predict / Prediction at 99%. $591K has traded across 28 outcomes on Kalshi and Polymarket. The market is expected to resolve by Oct 31, 2026.

This market will resolve according to Donald Trump's approval rating as reported by RealClearPolling at 5:00 PM ET on October 30, 2026. This market's resolution source will be RealClearPolling's presidential job approval poll average, https://www.realclearpolling.com/polls/approval/donald-trump/approval-rating, specifically the value in the "Approve" column of the "RCP Average" row of the table titled "President Trump Job Approval" as displayed at 5:00 PM ET on the resolution date. Any updates or revisions to the RCP Average published after this time will not be considered, except for corrections of data integrity issues as described below. Changes in the methodology by which RealClearPolling calculates its average will have no bearing on the resolution of this market. In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after the date on which such data is first released to allow for corrections. Data integrity issues refer only to clerical or other similar errors in the underlying data, and do not include cases where RealClearPolling differs from alternative sources. If the RCP Average is unavailable at 5:00 PM ET on the resolution date, this market may remain open until the end of the third calendar day (ET) after the resolution date. If the RCP Average has not been updated by then, the most recent RCP Average published prior to 5:00 PM ET on the resolution date 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.
