How does Polymarket Trade choose which markets to show on the homepage?

Short answer

Polymarket Trade's homepage surfaces markets that are actively contested and liquid, prioritizing questions where the odds are closer to even and real trading volume is present. Markets that have already drifted toward near-certain outcomes, or that attract little trading activity, are ranked lower or filtered out entirely. The goal is to show you markets where the outcome is still genuinely uncertain and where other traders are actively participating.

What to know

Prediction markets become most useful and informative when they are still being actively debated by traders. A market sitting at a very high or very low probability means most participants have already formed a consensus, which reduces both the informational value and the trading interest. Polymarket Trade's ranking logic reflects this by treating price distance from 50% as a signal that a market may be past its most interesting phase.

Liquidity is the other major factor. A market can appear contested on paper but have almost no real trading behind it, which means prices are unreliable and filling an order at a fair price is difficult. Volume and order book depth act as quality signals, helping the homepage filter toward markets where prices reflect genuine disagreement among enough participants to be meaningful.

The homepage also groups markets by category, allowing the selection logic to work within topic areas like politics, economics, sports, and technology. This means a contested, liquid market in a quieter category still has a path to visibility rather than being crowded out entirely by one dominant topic.

Finally, recency and event timing play a role. Markets tied to events that are approaching or currently unfolding tend to attract more attention and trading, which naturally lifts their ranking signals. Markets for events that resolved long ago or that have distant end dates with little current news context tend to rank lower.

Key points

• Markets with odds closer to 50/50 are ranked higher because they signal genuine uncertainty and active disagreement among traders.
• Markets with higher trading volume and deeper order books receive priority as a quality signal for price reliability.
• Near-decided markets, where probability has moved toward a very high or very low value, are deprioritized because informational value and trader interest both tend to drop.
• Category grouping ensures a variety of topics appear rather than a single popular category dominating all homepage slots.
• Event timing and recency influence ranking, with markets tied to upcoming or developing events naturally generating more trading activity.
• The system filters toward markets where a new participant can realistically trade at a fair price, not just markets that look interesting in name only.

How it compares

• Traditional news headlines: editors choose what is newsworthy based on judgment and audience interest. Polymarket Trade's ranking is driven by market data, so what appears is shaped by where actual trading is happening, not by editorial selection.
• Opinion polls: polls sample a fixed group at a point in time. A prediction market homepage reflects continuous, real-money updating by many independent participants, and the homepage ranking responds to that activity level in near real time.
• A generic market list sorted by newest: sorting purely by creation date would surface inactive or already-decided markets alongside active ones. The homepage ranking avoids this by weighting activity and odds position, not just when a market was created.
• Sportsbook odds boards: a sportsbook shows lines set by the house. Polymarket is a peer-to-peer market, so prices emerge from trader behavior, and the homepage amplifies the markets where that behavior is currently richest.

FAQ

Why would a market with extreme odds, like 95% or 5%, not appear on the homepage?

When a market has moved far from even odds, most traders have already reached a consensus view, which means there is less active debate and usually less volume. The homepage favors markets where the question is still open, so extreme-odds markets tend to rank lower unless they are generating unusually high trading activity.

Does the homepage show every category equally?

The homepage aims to provide variety across categories rather than letting one topic consume all visible slots. A category with strong markets will be well represented, but the system also creates space for contested, liquid markets in other categories to appear.

Can a low-volume market appear on the homepage if its odds are near 50/50?

Volume and liquidity matter alongside odds. A market that looks contested on price alone but has thin trading is less useful to participants because prices may not be reliable and orders may be hard to fill at fair terms. Both factors together determine ranking.

Does the homepage change throughout the day?

Market activity fluctuates, and ranking signals like volume and odds move in real time as trades happen. A market gaining sudden attention due to breaking news or a major trade will naturally improve its ranking signals, while one going quiet will gradually fall back.

Are all Polymarket markets eligible to appear, or is there a curation step?

The homepage reflects active, open markets that meet basic criteria like accepting orders and having meaningful liquidity. Markets that have closed, are no longer accepting trades, or have resolved are excluded from homepage consideration regardless of their historical activity.

How is this different from a watchlist or personalized feed?

The homepage is a general discovery surface based on market-wide signals like volume and odds position. It is not personalized to any individual user's history or preferences. A watchlist, by contrast, is curated by the user based on their own interests.
