Prediction market interfaces look simple, but the useful signal is in the relationship between price, volume, liquidity, and event design. This guide explains how to read those signals so you can interpret odds more carefully and use Polyguana's rankings as a faster starting point.
On Polymarket, a YES share priced at 65 cents implies the market currently assigns roughly a 65% probability to that outcome. If the event resolves true, the share settles at $1.00. If it resolves false, it settles at $0.00. That makes the displayed price both a tradeable asset and a live estimate of collective belief.
This is why prediction markets are so intuitive once you know the mapping: 30 cents means 30%, 50 cents means 50%, and 82 cents means 82%. You are not reading sportsbook-style odds or a payout multiplier. You are reading a probability that is constantly updated by buyers and sellers.
A 65% market is not a promise that the event will happen. It means that if the market were well calibrated across many similar cases, outcomes priced around 65% should resolve true about sixty-five times out of one hundred. The difference matters. Good forecasting is about calibrated confidence, not absolute certainty.
Volume tells you how much real money has interacted with a market. In general, higher-volume markets are more reliable because more participants have had the chance to express a view, challenge stale assumptions, and correct obvious errors. A quiet market can still be right, but it is usually easier to push around and harder to trust.
Context matters, though. One burst of volume around a breaking headline is different from steady turnover over several days. When you use Polyguana, compare recent flow with longer-run participation. A market that is both active now and consistently liquid over time is usually a stronger information source than a market that only spikes once and then goes dormant.
Mispricing often shows up when closely related markets disagree in ways that cannot all be true at once. If one contract implies a candidate has an 80% chance to win a state, while a broader election basket implies the opposite directional story, something may be stale, thin, or simply underfollowed. Cross-market comparison is one of the fastest ways to generate hypotheses.
Another signal is when the last traded price looks dramatically different from the current midpoint or from comparable markets. Outliers can appear because a small order hit an empty book, because the market has not updated in a while, or because new information has only reached one side of the order book. The right response is not to assume free money. It is to check volume, spread, and freshness before trusting the print.
The bid is the best price someone is willing to pay right now. The ask is the best price someone is willing to sell for. The gap between them is the spread. Tight spreads usually mean the market is liquid and the displayed price is actionable. Wide spreads mean the visible odds may be more fragile than they look.
Depth answers a different question: how much size can trade near the current quote? A market can have a tight top-of-book spread but still be shallow, meaning a moderate order would move the price sharply. That is why experienced traders read depth together with spread. Good execution quality is about both.
The rankings table is designed to help you move from browsing to analysis faster. Start with the default sort for the mode you are in. Pulse is best for discovering what the market is reacting to now. Trader is best when you care about volume, liquidity, spreads, and fast execution quality. Analyst is better when you want to compare probability context, timing, and market structure more deliberately.
When you scan the top markets table, look at four things together: the price, the recent change, the 24-hour volume, and the quality or liquidity indicators. That combination tells you whether a move is both meaningful and tradable. If a market looks interesting, open the detail view, inspect the history, then compare it against related events instead of treating one price in isolation.
Once you know how to read the odds, the next step is understanding how Polymarket trading works and how Polyguana ranks those markets.
