Polyscope scans over 2,000 active Polymarket markets for whale trades, probability shifts, volume spikes, and emerging markets — then pushes the signal to Telegram in real time so you never have to babysit a dashboard.
A useful Polymarket scanner should not just dump raw market data in your lap. It should watch the market continuously, filter out low-value noise, and surface the changes that traders actually care about — then deliver those changes where you already are.
That is what Polyscope is built for. It monitors over 2,000 active Polymarket markets across every category — politics, sports, crypto, culture, world events — and detects four types of meaningful movement: whale trades, probability shifts, volume spikes, and emerging markets.
When a condition is met, the scanner fires an alert to Polymarket Telegram alerts with full market context. No dashboard to check. No tab to keep open. No manual scanning through hundreds of markets hoping to spot the move.
The scanner connects to Polymarket's CLOB WebSocket feed and processes every trade event in real time. When a single trade crosses $5K, $10K, or $20K in USD value, a Polymarket whale alert fires immediately with trade direction, dollar size, and order book context. There is no polling delay — detection happens the instant the trade executes.
Every 5 minutes, the scanner snapshots each market's YES probability and stores it in a rolling 2-hour window. When the absolute change crosses 5, 10, or 20 percentage points compared to the oldest active snapshot, a directional alert fires showing the baseline and current value.
The scanner tracks each market's 24-hour trading volume and compares it against the baseline from the rolling snapshot system. When the ratio crosses 2x, 5x, or 10x — and the market clears a minimum $10,000 volume floor — a spike alert fires. This prevents false positives from illiquid noise.
Every 5 minutes, the scanner ranks all active markets by 24-hour volume and compares the current top 20 against the previous cycle. When a market enters the top 20 for the first time, an alert fires with its rank — helping you spot heating-up narratives before they become crowded trades.
Polyscope's scanner combines two data ingestion methods to catch both fast and slow signals:
Real-time WebSocket streaming — For whale trade detection, the scanner subscribes to Polymarket's CLOB WebSocket endpoint and streams every last_trade_price event as it executes. Tokens are subscribed in batches across all active markets. The connection auto-reconnects with exponential backoff if interrupted, so coverage does not drop even during network instability.
Rolling snapshot system — For probability shifts, volume spikes, and emerging markets, the scanner polls Polymarket's API every 5 minutes and stores timestamped snapshots per market. Each cycle compares the current state against the oldest active snapshot in the rolling window (2 hours for probability, baseline for volume). This catches slower but meaningful changes that a real-time stream alone would miss.
The combination means the scanner detects sub-second events (whale trades) and multi-hour trends (probability drift, volume buildup) from the same system. For a full technical breakdown, see the detection methodology page.
Polymarket's website shows you one market at a time. To manually scan for opportunities, you would need to:
That is not a realistic workflow for a human. Polyscope's scanner does all of it automatically and pushes only the signals that cross meaningful thresholds — with order book context, spread data, liquidity depth, and sentiment analysis included in every alert.
The result is a feed that gives you the important moves without the manual labor. You spend your time evaluating signals, not hunting for them.
A raw signal is not enough. Every alert from the Polymarket scanner includes the context a trader needs to evaluate the move:
Smart cooldowns (30 minutes per market per alert type) prevent repetitive spam while still allowing different alert types to converge on the same market. The premium channel filters to only the highest-tier alerts for traders who want maximum signal density.
The scanner surfaces signals. What you do with them depends on your prediction market trading strategy. Common approaches include:
Signal-driven entry. Use whale alerts and probability shifts as entry triggers. When multiple signal types converge on the same market — e.g., a whale buy followed by a probability shift — the conviction for entry is stronger.
Opportunity discovery. Use emerging market alerts and volume spikes to find markets you were not watching. Many profitable Polymarket trades come from markets traders did not know existed until activity picked up.
Risk monitoring. Even if you already hold a position, scanner alerts help you track changes in the markets you are exposed to. A sudden probability shift or whale trade on the opposite side of your position is something you want to know about immediately.
The Polymarket trading course teaches a complete framework for interpreting scanner output and building a repeatable prediction market trading strategy around real-time signals.
