📊 Kalshi Prediction Markets Scraper

🚀 Export Kalshi prediction markets data in seconds. Structured records direct from the public api.elections.kalshi.com endpoint to CSV, Excel, JSON, or XML.

🕒 Last updated: 2026-05-29 · 📊 12 fields per record · Public REST API · Kalshi prediction markets

The Kalshi Prediction Markets Scraper turns the api.elections.kalshi.com public REST endpoint into a clean, structured dataset. It calls the endpoint with the parameters you supply, parses the JSON, and flattens each record into one row.

Dataset coverage depends on the upstream source. All field names are clean snake_case / camelCase, numeric strings are auto-cast to numbers, and upstream rate-limit notes are surfaced as a clean error record instead of crashing your pipeline.

📋 What the Kalshi Prediction Markets Scraper does

• Calls the public api.elections.kalshi.com endpoint.
• Parses the JSON response and flattens each record into a clean row.
• Casts numeric fields to numbers so they import cleanly into Excel and BI tools.
• Surfaces upstream rate-limit or error notes as a single-row error record instead of crashing.
• Exports as CSV, Excel, JSON, JSONL, XML, RSS, or HTML.

💡 Why it matters: The raw Kalshi prediction markets JSON is verbose and hard to consume in spreadsheets. This actor normalizes the payload into one row per record so the data drops straight into pandas, BigQuery, or a Google Sheet.
