Who this guide is for
US adults who can already see a Polymarket card and now need to read the last traded price on that card — the last match that already printed — before they buy. Official market-book stats name lastTradePx. If the live card says Last or Last trade, follow that word. This is not how to read volume, not how to read liquidity, not how to read Yes/No prices, and not how to read price history. Those pages are the tape amount, the sitting size, the cents-as-chance display, and the chart. This page is only the last print on one card. Then we link out. Polymarket is the only live outbound on this page.
Where last price lives on the card
Official Browse Markets names current Yes and No prices on each card — not Last. Official Markets BBO API names lastTradePx. Official Place a Trade does not reprint a Last chip on the swipe we checked. If the live app uses a different label, follow that label — we will not invent one.
Open one card — last price is the last match on that ticket
Official Browse + Place a Trade
Official Browse Markets: each tile shows the market question, the current Yes and No prices, and a resolution date. Official Place a Trade: tap any market to open it. That opened ticket is where you look for the last matched print if the live screen shows one. Official Browse Markets does not list Last price on the tile. We will not invent a home-screen Last chip those pages do not print. If the sports desk is hidden where you live, stop.
Official US retail help does not reprint a Last header
Action, not an invented tab
Official Place a Trade, Official Browse Markets, Official Prices & Market Data, and Official Glossary do not reprint a retail column or tab labelled Last, Last price, Last trade, or Last print on the swipe we checked. We will not invent one. The action is: on that opened ticket, look at the most recent matched price that sits with the market if the live app prints it. If the live control is labelled Last, Last trade, Last price, or something else — or is missing — use the live screen, then still read the BBO. Official Website vs App: US residents do that in the Polymarket US app.
API lastTradePx is a field name — not a phone chip we will paste on
Official Markets BBO API
Official Markets BBO API names lastTradePx as the last trade price, plus currentPx, bestAsk, and bestBid. Official market-book stats name lastTradePx and lastTradeQty as the price and quantity of the most recent trade. Official Valuation API names LAST as last traded price on those valuation endpoints. Those are published field names. Official Place a Trade does not reprint them as a Last chip. We will not paste an API field onto the US swipe as if the retail page printed that menu.
If the live card says Last or Last trade, use that live word
Action, not an invented header
Hard rule: if official US help names the field, we name it. Official market-book stats name lastTradePx. Official Time & Sales names Last Price and Last Quantity on the exchange tape — that is a report, not a confirmed phone header. Official Browse Markets names current Yes and No prices, not Last. If the live US card already prints Last, Last price, Last trade, or Last print, follow that live label. If no such word is there, the action is still: find the most recent match on the opened ticket, then check whether the BBO still sits there.
Official US docs · lastTradePx named · no invented Last chip · follow live labels
Last price is not volume, liquidity, or the Yes/No quote
Official How are Polymarket odds determined? reprints the last match when orders fill. Official Prices & Market Data is the live BBO you can take. See how to read Yes/No prices for the display — this page does not repeat that cents walk.
Last price is a completed match — history
Official lastTradePx + odds FAQ
Official market-book stats: lastTradePx is the most recent trade. Official How are Polymarket odds determined?: prices update whenever a buy or sell is matched. A last-price stamp is that print. It already happened. It is not a hold, not a sportsbook lock, and not a promise the next swipe pays the same cents. We do not reprint a live last.
The Yes/No number on the tile is a display — the BBO is the trade
Official Browse + Prices & Market Data
Official Browse Markets shows current Yes and No prices on the card. Official Prices & Market Data: a market order fills at the best available price on the other side right now — the BBO. Official Spreads: you buy at the ask. Official Glossary: the BBO is the tightest pair at the top of the book. A last print can sit one number; the best ask can sit another. How to read Yes/No prices is the cents-as-chance read. This page is only the last match.
Last price is not volume, and it is not liquidity
Two other stamps
How to read volume is how much has already traded — the tape amount. How to read liquidity is how much size is sitting on the book now. Official Glossary: size is contracts available at a price; liquidity is how much of that size is there to trade. A last print can be 40¢ after a busy tape or after a thin tape. Neither stamp is the last match, and the last match is neither stamp. We link those walks instead of cloning them.
Last print = history · Yes/No tile ≠ the ask · volume / liquidity stay linked
Why a small order still might not fill at the last price
Official Liquidity is posted size now. Official Price Impact is why a thin clip walks. A last print does not refill that book.
A small clip can still miss the last print
Official Liquidity + Price Impact
Official Liquidity: posted size is what can trade at a level before the next price is touched; treat the displayed price as dynamic, especially in live sports. Official Price Impact: if a clip is larger than the size sitting at the best price — or if that clip has already been lifted — the rest walks. Official Glossary: slippage is the gap between the price you expected and the price you received. The last print is what someone else already paid. It is not the size still waiting for you.
Thin versus the last print is the usual miss
Official Spreads + Liquidity
Official Prices & Market Data: a tight spread means the market is liquid; a wide spread means fewer people are trading. Official Liquidity: size can vanish late in a quarter, in overtime, after a score or injury, or when the result looks decided. A last print from a minute ago can sit next to an empty best ask. A one-contract swipe still pays the ask that is there now, not the print that already left. How to set an order size is typing that clip. This page does not clone it.
A last print is not a floor and not settlement
Official Settlement + Slippage
Official Market Settlement and Official Prices & Market Data: a winning contract settles at $1.00 and a losing contract at $0.00. Official Price Slippage: markets stay open until the outcome is confirmed, even if the result looks certain; liquidity can thin on the side already priced as likely. Official How are Polymarket odds determined?: Polymarket US does not set prices. A last print at 90¢ is not a locked $1, and a last print at 10¢ is not a locked zero. Nothing here is investment advice.
Official Liquidity · last print ≠ resting size · thin book slips · no live last
This is not limit price, share, order size, or open orders
People mash “what just printed” into “what I should type.” Official US docs do not. How to set a limit price is the cents you enter. How to read a share is the unit. This how-to does not clone either.
This is not how to set a limit price
Print ≠ the cents you type
How to set a limit price is the cents you will pay or sell at on a new order. Official Glossary: a limit that does not cross rests; a marketable limit fills at the best available price shown. The last print is someone else’s completed match. Typing that same number does not make it your fill if the book has moved. Leave the typing walk on its own URL.
This is not a share, an order size, or your open orders
Leave those how-tos linked
How to read a share is one Yes/No unit that pays $1 or $0. How to set an order size is how many of those units one new order asks for. How to read open orders is the resting list you already have working. Official Glossary: an open order is waiting on the book to be filled. None of those pages is the last public print on the card. We link them instead of reprinting the click path.
This is not the chart, and it is not your trade history
One print ≠ the series
How to read price history is the chart and the last-trade series on the ticket. How to read trade history is your past fills. Official Time & Sales is the exchange tape (Last Price, Last Quantity) — a report, not a phone tab we invent. This page stops at the single last-price figure on the card. If you wanted the whole tape or your own History row, those are later walks.
Last ≠ limit · share / size / open orders stay linked · chart / your history stay linked
How to read last price on a card
-
Step 1
Open one card in the Polymarket US app — not a tweet and not the chart how-to
Find the market, then look at a single tile. Official Website vs App: US residents browse and trade in the Polymarket US app, not on polymarket.com. Official Browse Markets: the card shows the question, the current Yes and No prices, and a resolution date. Official Place a Trade: tap the market to open it if you need the last match on the opened ticket. If the sports desk is hidden where you live, stop. How to read Yes/No prices is the cents on that tile. This page is only the last print.
-
Step 2
Read the last traded price if public docs or the live card label it
Official market-book stats name lastTradePx as the most recent trade, plus lastTradeQty for that clip. Official Markets BBO API names the same lastTradePx field. Official Time & Sales names Last Price on the exchange tape. Official Place a Trade does not reprint a retail header labelled Last, Last price, or Last trade on the swipe we checked. If the live card already uses one of those words, follow that live label. If the last print is blank, do not treat the Yes/No display as that print.
-
Step 3
Treat last price as history — then still check the BBO and posted size
Official How are Polymarket odds determined?: prices update whenever a buy or sell is matched. Official Prices & Market Data: a market order pays the best available price on the other side right now. Official Spreads: you buy at the ask. Official Liquidity: posted size is the clip that can still fill. A last print can sit far from that ask. A small order still might not fill at the last price if that size is gone. We do not reprint a live last or a live ask.
-
Step 4
Do not mash this stamp onto volume, liquidity, or the Yes/No quote
How to read volume is how much has already traded. How to read liquidity is size sitting now. How to read Yes/No prices is the displayed cents as a chance. How to read price history is the chart. This page is only the last match on the card. If you skip those other lines, you have not read the ticket.
-
Step 5
Then leave share, order size, limit price, and open orders on their own pages
How to read a share is the $1 / $0 unit. How to set an order size is how many units you ask for. How to set a limit price is the cents you type. How to read open orders is your resting list. Event contracts can settle at zero. Trade only what you can afford to lose. Nothing here is investment advice.
Blocked and contested states
Reported unavailable as of June 2026: Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada and Ohio. That list is not a promise it stays still — litigation around sports event contracts in particular can narrow or shift access. If you are in a listed state, do not treat a last print as a fill on the assumption the desk is open. If you are in Florida or another green-light state, still confirm the ticket appears and still accepts orders before you send money.

What you will not get from this page
A dollar welcome match, a paste-this promo code, an invented Last / Last trade / Last print tab Official Browse Markets does not print, a live last or a live ask, a cloned volume / liquidity / Yes-No / price-history walkthrough, a newsletter form, or claim buttons for Kalshi, DraftKings, FanDuel, Underdog, Sleeper, PrizePicks, Hard Rock or BetRivers. We could not verify a standing official US welcome bonus on Polymarket’s own terms. Other publishers’ partner codes are theirs; we do not copy them. The honest user-facing line is still US access via CFTC-regulated QCEX — official market-book stats name lastTradePx as the most recent trade, official Browse Markets prints current Yes and No prices not Last, official help does not reprint a Last chip we invent, that print is not volume and not liquidity, a small order still might not fill at the last price if size is gone, and if the live card prints Last or Last trade, use that live word.
