Polymarket

Query prediction market data from Polymarket's public API (no auth required).

Quick Start

# Top markets by 24h volume
python3 scripts/polymarket.py --top

# Search markets
python3 scripts/polymarket.py --search "trump"

# Get specific market by slug
python3 scripts/polymarket.py --slug "will-trump-win-the-2024-election"

# List events (grouped markets)
python3 scripts/polymarket.py --events

Script Location

skills/polymarket/scripts/polymarket.py

API Endpoints

The script uses gamma-api.polymarket.com:

  • /markets - Individual markets with prices, volumes
  • /events - Event groups containing related markets

Output Format

Markets show: question, Yes/No prices (as percentages), 24h volume, total volume.

Interpreting Prices

  • outcomePrices are 0-1 representing probability
  • Price of 0.65 for "Yes" = market thinks 65% chance of Yes
  • Higher volume = more liquid, more reliable signal
