Polymarket New Markets Scraper & Exporter
Scrape newly listed Polymarket markets by category, including event titles, market questions, outcome prices, and start/end dates. Export to CSV, Excel, or JSON in one click.
How It Works
This exporter calls Polymarket's public Gamma API to load new markets for the selected category. Results are flattened into a clean table for export.
Each row includes the event context plus market-level fields like question text, outcome prices, and end dates.
