How it resolves

The rules, word for word as Polymarket publishes them:

This market will resolve to "Oil < $85; R Senate" if oil is less than $85 at the close of trading on November 2, 2026, and the Republican Party wins control of the United States Senate in the 2026 United States midterm election. This market will resolve to "Oil < $85; D Senate" if oil is less than $85 at the close of trading on November 2, 2026, and the Democratic Party wins control of the United States Senate in the 2026 United States midterm election. This market will resolve to "Oil ≥ $85; R Senate" if oil is greater than or equal to $85 at the close of trading on November 2, 2026, and the Republican Party wins control of the United States Senate in the 2026 United States midterm election. This market will resolve to "Oil ≥ $85; D Senate" if oil is greater than or equal to $85 at the close of trading on November 2, 2026, and the Democratic Party wins control of the United States Senate in the 2026 United States midterm election. Oil price: The oil price component will be determined based on the Close price for the Active Month of ICE Futures Europe WTI Crude Futures (denoted by Pyth as "CLL") for the November 2, 2026 trading day. For a standard full trading session, the closing price refers to the Pyth "Close" value of the 1-minute candle corresponding to the final minute of regular trading hours on the primary exchange. Closing prices will be used exactly as published by Pyth, without rounding. If the Active Month contract does not trade at all during the relevant trading session, or if the listed date is not a trading day under the applicable trading-hours schedule, the oil price component will be determined based on the Close price for the most recent prior trading day. For the purposes of this market, trading days will be determined according to the applicable trading hours schedule for the underlying market (See: "Trading Hours" at https://www.ice.com/products/213/WTI-Crude-Futures). The trading session for a given business day typically begins at 8:00 PM ET on the prior calendar date, except for the session dated Monday, which begins at 6:00 PM ET on the preceding Sunday, and where modified by holiday or other special hours (See: https://www.ice.com/holiday-hours). The Active Month is the nearest listed contract, except during that contract's final three trading sessions. At the open of the third-to-last trading session, the next listed contract becomes the Active Month. Each contract's last trading day will be determined by ICE Futures Europe per the WTI Crude Futures contract specification (generally the 4th US business day prior to the 25th calendar day of the month preceding the contract month, or five US business days prior if the 25th calendar day is not a US business day). The last trading day for each contract is posted at https://www.ice.com/products/213/WTI-Crude-Futures/expiry. For example, if the last trading session for the nearest listed contract is the session for Monday the 20th, the next listed contract would become the Active Month at the start of the trading session for Thursday the 16th (8:00 PM ET on Wednesday), assuming a standard trading calendar. If the specified day has no valid Pyth Close value for the 1-minute candle corresponding to the end of regular trading hours on the primary exchange, the market will use the last valid Pyth price achieved during the regular trading hours of the primary exchange as the effective closing price. If no valid Pyth price exists for that trading day due to a system outage, data failure, or other disruption, the official close price published for the Active Month WTI Crude Oil Futures contract by ICE Futures Europe will be used to determine the closing price for that day (See: https://www.ice.com/report/10 with "T-West Texas Intermediate Light Sweet Crude Future" selected). In the event of a contract specification change, feed change, or similar structural modification affecting the underlying market during the listed time frame, this market will resolve based on adjusted prices as displayed on Pyth. The resolution source for the oil price component will be Pyth, specifically the "Close" value for the relevant 1-minute candle for the Active Month WTI Crude Oil Futures contract by ICE Futures Europe available at https://app.pyth.com/explore?search=CLL. Historical 1-minute candles may be accessed by appending a Unix timestamp (seconds) to the Pyth chart URL using the "t=" parameter. Senate: A party wins control of the United States Senate if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the party that wins control of the chamber is the party that wins half of the voting seats and holds the Vice Presidency. If the outcome remains ambiguous after applying the above criteria, the chamber will be deemed controlled by the party with which the first selected President Pro Tempore of the Congress that convenes after the specified election is affiliated. The following rules govern the counting of seats for determining which party wins control of the chamber. All regular and special Senate elections that determine representation in the upcoming 120th Congress and are scheduled to take place in November 2026 as of October 31, 2026 are included. Runoffs for qualifying elections will determine attribution of the relevant seat, even if they take place after November 2026. Vacant seats for which no election or special election to fill the seat is scheduled to take place in November 2026 as of October 31, 2026 will be treated as held by the party affiliation of the most recent member to hold that seat. For seats contested in the specified election, seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected. For seats not contested in the specified election, seats

How results are settled:

Polymarket markets are typically settled through UMA's optimistic oracle: a result is proposed after the event, can be disputed during a challenge window, and is final once undisputed or decided.

How to read these odds

A share of each outcome costs its chance in cents and pays $1 if it happens, so 75% means about 75¢ a share and roughly 1.34x back if right. On a ladder of dates or levels each rung is its own yes/no market, so the prices don't add up to 100%. Guides: reading Polymarket odds, odds to probability, glossary, how election odds work.
