Election night is not resolution day
The US midterms are four weeks out and the chamber-control markets are among the busiest anywhere. The date on the market and the date it pays can be months apart, and the rules say exactly why.
The US midterm elections are on Tuesday 3 November. Four weeks out, markets on which party controls each chamber, on individual Senate races and on ballot measures are live and active, and they will get busier every day until polls close.
An evaluation opened this week runs straight through election night. That makes it worth being precise about something most people only discover afterwards: the night the results come in and the moment a market actually pays are different events, and they can be a long way apart.
Your Call evaluations trade Polymarket, so the example below is that venue’s Senate control market. Nothing here is a view on who will win.
The date on the market is not the payout date
The Senate control event shows an end date of 4 November at 04:59 UTC, which is 11:59pm Eastern on election night. It is natural to read that as when the question is settled.
The rules underneath say otherwise. Paraphrasing them closely:
- A party controls the Senate if it wins a majority of the voting seats. At an even split, the party holding half the seats plus the vice presidency controls it. If that is still ambiguous, control follows the party of the member chosen as President pro tempore.
- Every November election scheduled as of 31 October counts, and runoffs count even if they are held after November.
- A member-elect who switches party or leaves before Congress organises is counted under the party they were elected as.
- Independents count toward a party if they caucus with it or announce that they will. If that is still unknown by 4 January at 11:59pm Eastern, they count toward nobody.
- The resolution sources are official state election authorities, the US Congress, and a consensus of credible reporting.
Read those as a list of reasons the market might not settle on the night. A runoff and a caucus deadline are both written into the contract, and each pushes the earliest possible answer later.
This has happened before
The runoff clause is not hypothetical. Georgia requires a majority to win, and its state government lists 1 December 2026 as the general election runoff date. Georgia has a US Senate seat on the ballot this year.
In the 2020 cycle, control of the Senate was not settled until Georgia’s two runoffs on 5 January 2021, two months after election day. A market written the way this one is would have stayed open the whole time.
We do not know whether anything like that happens this year. Nobody does. What can be known now is that the contract allows for it.
Called is not certified
On election night, news organisations project winners. Those projections are not official results; states count, canvass and certify over the following weeks, and close races can go to recounts. This market names official authorities and a consensus of credible reporting as its sources, so a clear outcome may resolve well before certification. A close one may not.
After a proposed outcome, settlement on this venue runs through an oracle with a challenge window, and a dispute escalates to a vote that takes days rather than hours. What the resolution criteria decide covers that process in full.
Why it matters more inside an evaluation
The window is shorter than the question. A 30-day evaluation opened today ends around 4 November. A position in an event that stays open into December or January cannot settle inside your window. Whatever it contributes has to come through its mark, or through closing it early into whatever book exists at the time — and closing does not reset that event’s cap. Every event contributes at most 0.5% of account size toward the 10% Equity Growth Target, so the resource that runs out is the number of events that actually finish. The Double Time add-on extends the window to 60 days, but it does not make a runoff happen sooner.
Eligibility is its own check. Markets must resolve within 60 days to be eligible. Whether a particular election market meets that is something to confirm on the platform before you size, not something to assume from the date on the tile. We are not going to guess how any specific market is classified.
Election night is one trading day. The daily drawdown limit is 3% of account size and resets at 5PM Eastern. Polls close across the country from the early evening onwards, and returns arrive for hours after that. The whole night, from the 5PM reset on 3 November to 5PM on 4 November, lands inside a single daily limit, and every limit is measured on live equity.
Open profit on the night is not safe. Marks on race markets swing as counties report, and the maximum drawdown trails your equity high-water mark, which never locks. A position that runs up on early returns and gives it back by morning has moved your floor permanently. Crypto volatility and a drawdown that counts open profit works through the same mechanic with numbers.
Race markets move together. Individual seats are separate events to the per-event cap. A national swing moves many of them at once. Twenty events is not twenty risks is the piece to read before building a book of them.
Spreads widen when it matters. On a fast night, books thin out and the displayed price can switch from the midpoint to the last trade. The number on the tile explains why the figure you see may not be one you can trade.
The short version
Read the resolution rules before election night, not after it. On this market they name a runoff clause, a January caucus deadline and three resolution sources, and any of them can put the payout weeks after the result looks obvious. Inside a fixed evaluation window, a correct view that settles too late never reaches settlement at all — only its mark does, and the mark is the part that swings.
