Polymarket Monitor

Track prediction market prices, volume, and liquidity on Polymarket using the Gamma API and CLOB API.

When to Use

Use this skill when the user asks about:

Trending or popular Polymarket markets

Current price or probability for a prediction market

Volume or trading activity on a market

Order book depth or liquidity for a specific outcome

New or recently created prediction markets

Price movements or volume spikes on Polymarket

Key Concepts

Price = Implied Probability: A contract at $0.65 means 65% implied probability

Token ID: Each outcome (Yes/No) has a unique token ID used by the CLOB API

Condition ID: The unique identifier for a market (question) in the Gamma API

CLOB: Central Limit Order Book — where bids and asks are matched

Operations
