Polymarket data

Polymarket data for liquidity, depth, volume, open interest, and holders

Polymarket data is most useful when price is paired with liquidity, order book depth, open interest, volume, and holder distribution. Prediction Market News makes those metrics crawlable, filterable, and visible with freshness timestamps.

Market screener

Sort by volume, OI, liquidity/depth, spread, and holder concentration.

Rankings

Find the highest-volume, deepest, and most concentrated active markets.

LLM context

Use curated public context while the JSON API remains protected from anonymous traffic.

Liquidity and order book depth

Liquidity alone can be misleading, so the screener pairs headline liquidity with spread and resting depth near the midpoint. This helps separate active markets from markets where the displayed price is hard to trade.

Open interest and volume

Volume shows trading activity, while open interest helps identify markets with real capital locked in net positions. The Polymarket data pages show both so analysts can spot heavily traded but thinly backed markets.

Holder concentration

Holder count and top-holder share help users understand distribution risk. A market with a high top-holder share can behave differently from one with broad participation.

LLM-readable market facts

Core Polymarket data appears in server-rendered HTML and a JSON API so search engines and LLM tools can extract current market facts without relying on client-side JavaScript.
