Polymarket data
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.
Sort by volume, OI, liquidity/depth, spread, and holder concentration.
Find the highest-volume, deepest, and most concentrated active markets.
Use curated public context while the JSON API remains protected from anonymous traffic.
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.
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 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.
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.

Prediction Market News shows active Polymarket markets with liquidity, total volume, 24 hour volume, midpoint, spread, depth, open interest, holder count, top holder share, and freshness timestamps.
The site uses public Polymarket Gamma, CLOB, and Data API responses through a Cloudflare REST snapshot ingestion pipeline.
The launch baseline refreshes market snapshots on a scheduled Cloudflare Worker cadence and displays freshness timestamps on metric rows so stale data is visible.
