How to read a prediction market page

Eighteen figures, each in one paragraph: nine on a market page, nine on a trader profile.

A prediction market turns a question into a price. On Polymarket each outcome is a share that pays $1 if it happens and nothing if it does not, so a Yes share at 36¢ means traders, with money on the line, put the chance at about 36%. Everything else on a market page describes how much to trust that number: how much money has tested it, how easy it is to trade against, and who is on each side.

See the figures on a live page: the most traded markets or the trader leaderboard.

Market pages

The nine figures on a market page

9 stops

From the price itself to the day it stops trading.

  1. 01

    Yes and No prices

    Each outcome trades as a share that pays $1 if it wins and nothing if it loses. Prices are quoted in cents, and Yes plus No add up to about one dollar.

  2. 02

    Implied probability

    The Yes price read as a chance. A share at 21.5¢ implies 21.5%, but fees, available depth and who participates can affect that price. A market price is not a calibrated forecast or a verdict.

  3. 03

    24h volume

    Dollar value of shares that changed hands in the last 24 hours. High volume means the price is being tested by real money; low volume means a few trades can move it.

  4. 04

    Liquidity

    Reported dollars resting in the order book. The available size on your side, at the prices you would accept, determines what can fill. A large total alone does not guarantee an execution near the quoted price.

  5. 05

    Spread

    The gap between the best bid and the best ask. A tight spread makes entry and exit cheap; a wide spread is a cost paid on every round trip.

  6. 06

    Top holders and concentration

    The wallets holding the most shares on each side, and how much of the public holder list the largest ten control. Concentration shows whether a market is a crowd or a handful of large positions.

  7. 07

    Trade tape

    The public trades, newest first: which wallet bought or sold which outcome, at what price, and when. It is the market's own diary, and every wallet on it links to a trader profile.

  8. 08

    Price history

    Daily closes of the Yes price over the market's life. The range shows how sure or split the crowd has been; the move shows which way it has been changing its mind.

  9. 09

    Close and resolution

    Trading stops at the close time. The outcome is then settled by the resolution source named in the rules. A closed market is not resolved until the venue reports it, so the two states are shown separately.

Trader profiles

The nine figures on a trader profile

9 stops

What a wallet has made, how, and how much of that record Polymarket publishes.

  1. 01

    Rank

    Position on Polymarket's all-time profit leaderboard. The Vultax leaderboard lists 80,000 of those wallets by the same profit figure; Polymarket's ranking also counts wallets outside it.

  2. 02

    Total P&L

    Lifetime profit and loss for the wallet, realized and unrealized combined, as Polymarket's leaderboard reports it. It is a record of what happened, not a forecast of what comes next.

  3. 03

    Volume

    Lifetime dollars traded. Profit divided by volume is profit per dollar traded, not a return on capital: the same money can be traded many times.

  4. 04

    Position value

    What the wallet's open positions are worth at current prices. Zero is shown only when Polymarket reports zero; a value that could not be read stays unavailable.

  5. 05

    Win rate

    Share of settled positions that closed in profit. A high win rate with a small profit usually means many small wins and a few large losses.

  6. 06

    Gains and losses

    Winning markets summed against losing markets. The split shows whether profit came from many small wins or from a few big calls.

  7. 07

    Gains offset by losses

    Total losses as a share of total gains. Lower means less of the profit was given back; a value above 100% means the wallet lost more than it won.

  8. 08

    Markets and settled positions

    How many different markets the wallet has traded and how many of its positions have settled. Breadth alone does not establish skill.

  9. 09

    Recent trades and their dates

    Polymarket lists a wallet's most recent trades, not its whole history. Each figure on a profile carries the time it was read, so an old number is never shown as live.
