How to Read an End Date on Polymarket (US 2026)

Official Browse Markets: each market shows the market question, the current Yes and No prices, and a resolution date. That is the named retail clock on the tile. Official Place a Trade: tap any market to open it. Look at that same date on the opened card. We will not invent a home-screen chip labelled “End date,” “Close date,” “Ends,” or “Last trade” those pages do not print. If the sports desk is hidden where you live, stop.

Official Markets API names endDate and describes it as the market end date. It also names startDate and a closed flag. Official Events & Markets gives the event a start time. Those are record fields and a contest clock. They are not a retail tab labelled End date or Close date on the swipe we checked. A developer field is not a button we invent.

Official Market Rules include a Resolution Timeframe: when the outcome is evaluated. Teaching examples include “results available at 11:59 PM ET on the end date” and “if the event does not occur by 11:59 PM ET.” Those are published teaching lines, not a sports-game lock we reprint as tonight’s rule, and not a Close date chip on the browse card. Scroll the rules on the opened ticket if you need that window. If the block is blank or you do not understand it, do not click.

Hard rule: if official US help names the field, we name it. Official Browse Markets names resolution date. Official Markets API names endDate. Official Market Rules use “end date” in teaching copy. Official Place a Trade does not reprint End date, Close date, Ends, Closing, End time, or Last trade on the swipe we checked. If the live US card already prints End date, Close date, Ends, Closing, or Resolution date, follow that live label. If no such word is there, the action is still: read the printed date on the card, then see whether the book is still Open.

Official Market Resolution: markets stay open until the event is over, then resolve after the official result is publicly confirmed. Official Sports FAQs apply the same game-level rules to pregame and in-game trading unless a sport-specific section says otherwise. Official Prices & Market Data: Open means the market is still accepting orders. The date on the card is the scheduled end stamp — it is not automatically “the book just died.” Read the date, then still look at whether orders are accepted.

Official Prices & Market Data names Halted (trading has been stopped) and Expired (the market has ended and settled). Official “Can I sell early?”: you can close a position while the market is still open. After the book prints closed, that early exit is gone. We do not reprint a live countdown. If the card still shows a future date and the book is already Halted or Expired, the live state wins over the calendar.

A league schedule, a recap, or a kickoff we would type here is not the trading rule on this ticket. Official Trading Hours name a weekly Thursday 2:00–6:00 AM ET maintenance window for the exchange — that is desk downtime, not this market’s end date. Official Events & Markets start time is when the contest is scheduled to begin. How to check when a market ends is the fuller clock (start time versus last trade versus pay). This page is only the date printed on the card.

Official Market Rules keep Resolution Sources in the rules — who or what confirms the outcome. Official Market Resolution grades from the specific sources listed in the rules. The date on the card does not name a league, a wire, or an official result. How to read a resolution source is that grader. This page does not clone it. A calendar stamp is not “the tweet already settled this.”

How to sort markets by ending soon is a browse reorder — putting nearer dates first on the home-screen pile, or scanning many cards if there is no sort chip. This page is one card’s printed date. Reordering the list does not read this stamp. Reading this stamp does not hide basketball or put tonight first. Leave that sort on its own URL.

How to read a share is one Yes/No unit that pays $1 or $0. How to read a series winner is who takes the listed series, not tonight’s game. How to read a voided or canceled market and how to read a disputed resolution are what happens after the usual Yes/No grade waits or changes. This page stops at the date on the card. We link those walks instead of reprinting them.

Official Place a Trade: tap the market, pick Yes or No, enter a dollar amount or Max, review, and swipe. Reading the date happens one step earlier — on the card. It does not spend cash, rest a limit, or lock a price. Official Events & Markets: a market settles at $1.00 or $0.00 only for the contracts you hold. A future-looking date is not a reason to swipe without reading the sentence.

Official Events & Markets: one event can hold several Yes/No tickets. A moneyline, a player prop, and a longer sentence can sit under the same logos and still show different resolution dates. If you only read the headline, you can buy a ticket whose printed end is a different night than the game you thought you were on.

Official Market Clarification (on that other page) still says read the rules before you trade. This page’s cut is narrower: if the card has no date, the date contradicts the live Open / Halted / Expired word, or you cannot map the stamp to a real calendar day, stop. We will not invent a 2026 kickoff or a minute-count to fill the blank.
