A free Polymarket screener
PullToPar is a free screener for Polymarket. It reads every open market and turns each one into two tradeable rows: buying YES and buying NO. Both are priced at the real ask rather than the midpoint, then ranked by how fast the trade returns your capital. Free to use, with no paywall.
How it works
Polymarket lists thousands of open markets at any moment. Each has a YES side and a NO side, and either can be the better buy depending on where the price sits. PullToPar splits every market into both directions so you can compare all of them in one table.
Every row is priced at the best ask. That is the lowest price a seller is currently willing to accept, and it is what you would actually pay. Most tools quote the midpoint between the best bid and the best ask instead. Nobody trades at the midpoint. On a market quoting 97c bid and 98c ask, the midpoint flatters the trade by half a cent, and on thin markets that gap can swallow most of the profit.
Rows are then ranked by how quickly the money comes back. A trade returning 14% over three days and one returning 14% over nine months are not the same trade, and sorting by raw return alone hides that completely.
What the numbers mean
Cost is what one share costs in cents. At 87c, $100 buys about 115 shares.
Return is what those shares pay if the outcome happens. Each winning share is worth $1, so $100 at 87c becomes $114.94. Your profit is $14.94, which is 14.9%.
Implied chance is the same number read the other way. A price of 87c means the market as a whole is putting the outcome at roughly 87%. A cheap share with a huge return is cheap precisely because the market expects it to lose.
Spread is the gap between what buyers offer and what sellers ask, shown as a share of your profit. A 1c gap takes about 20% of the profit on a typical high-priced trade; 4c takes about half.
Important: this is not advice
PullToPar does not predict anything. It reports prices published by Polymarket and sorts them using arithmetic anyone can check. It has no opinion on which outcome will occur, and nothing on this site is a recommendation to buy, sell or hold any position.
A ranked list can look like a set of tips. It is not one. The ordering is a calculation on public prices, and the market's own price is the best available estimate of what will happen. A large return is the market telling you an outcome is improbable, not a signal that it is mispriced.
Prediction markets carry a real risk of losing everything you put in. A losing share is worth exactly zero, not a reduced amount. Nothing here accounts for your circumstances, and none of it is financial, investment, legal or tax advice. Make your own decisions, and never stake money you cannot afford to lose.
Prices and calculations are provided as-is and may be delayed, incomplete or wrong. Always confirm on Polymarket before trading.
Common questions
- Is PullToPar free?
- Yes. Every market, every filter and every calculation is free to use, with no paywall and nothing held back behind a paid tier.
- What does PullToPar do?
- It reads every open Polymarket market and turns each one into two tradeable rows: buying YES and buying NO. Each row is priced at the real ask, which is what you would actually pay right now, then ranked by how quickly the trade returns your capital if it wins.
- Why does it use the ask price instead of the midpoint?
- The midpoint is an average of the best bid and the best ask, and nobody can trade at it. If buyers offer 97c and sellers ask 98c, the midpoint says 97.5c but you pay 98c. On a market with a wide spread that difference can be most of the profit, so pricing at the midpoint overstates what a trade is worth.
- What does 'pull to par' mean?
- It is a bond term. A bond bought below face value drifts up toward face value as maturity approaches. A prediction-market share does the same thing: buy at 86c and at resolution it is worth either $1 or nothing.
- Does a high return mean a trade is good?
- No. A high return means the market thinks the outcome is unlikely. A share costing 5c pays 20x if it wins, and the price is telling you it usually will not. Return and probability are two views of the same number, not independent signals.
- Where does the data come from?
- Directly from Polymarket's public API. Prices refresh every 20 to 30 minutes while US markets are active and less often overnight, and the page shows when it last updated and when the next update is due.
- Does PullToPar predict outcomes or give advice?
- No. It reports published prices and sorts them arithmetically. It has no view on which outcome will occur and makes no recommendation to buy or sell anything.
