Balance of power, both chambers
5 separate Polymarket markets; YES prices sum to 100.6, bar widths scaled to 100.Race board
Every Senate, governor and House race market recorded by Kresmion, closest to 50 first, then by volume. Dem YES is shaded blue above 50 and amber below. A race with one stored leg shows n/a for the other: the legs are separate markets and one is never derived from the other. 7d is the Dem leg, or the named leg where no party leg is stored. Depth 1% is the bid / ask dollar depth within 1% of the mid from an order book recorded in the last 6 hours, n/a otherwise; a side reads in spread when 1% of the mid is narrower than the gap to that side's best quote (a low-priced leg), so no order can rest inside the band. A race whose last capture is older than 90 minutes shows its capture time. Markets listed on the venue and recorded by Kresmion; races the venue has not listed are absent.

Market depth: price impact of a $1k and $10k order
Average fill, distance from the best level and the taker fee, walked through the latest recorded Polymarket order book. Ask side takes offered YES shares, bid side takes resting bids. Fee in bps of stake at the average fill, fee / stake = rate x (1 - price). Books older than 6 hours are not used.

Seat counts, popular vote and other midterm markets

Method and sources
- YES means the contract pays out if the outcome in the market's own resolution rules occurs. Each price is the YES mid in percent.
- Capture: chamber-control markets about every 5 minutes, race markets on a slower rotation of under an hour (measured September 26, 2026). Each card shows its capture time.
- 24h and 7d changes compare the current price with the recorded price at that lookback, and are left blank when the nearest recording is not close enough to the label.
- Depth uses the latest recorded order book (top price levels per side) and the market's published fee schedule; books older than 6 hours are not used.
- Sources: Polymarket gamma and CLOB APIs. Methodology.
Questions
What do the numbers on this board mean?
Each number is the YES price of a prediction market, in percent, as recorded by Kresmion from the venue. A Senate control price of 62.5 for the Democratic leg means that contract traded around 62.5 cents per dollar of payout at capture time. It is a market price, not a Kresmion estimate or forecast.
Why can the Democratic and Republican prices add up to more or less than 100?
Each party leg is a separate market with its own order book, fees and traders, so the two YES prices are quoted independently. Kresmion shows both as recorded and never derives one leg as 100 minus the other.
How often is this board updated?
The chamber-control markets are captured about every five minutes and the race markets on a slower rotation of under an hour, as measured on September 26, 2026. The page itself is rebuilt at most once a minute. Each card shows its capture time in UTC.
Is this financial advice?
No. Kresmion reports prediction-market prices as market data for research context. Nothing on this page recommends any position.
Cite this data
Kresmion stores the venue's YES price on a fixed capture schedule. The figures here are those stored prices, the differences between them and walks of the recorded order book, not a Kresmion estimate.
