Kalshi Prediction Markets Scraper

Scrape Kalshi prediction markets by status, event ticker, or series ticker, up to a million per run. Every market comes with its ticker, category, prices, volume, and settlement data. No login or API key. Export to CSV, JSON, Excel, or XML.

Kalshi's official API needs an account, API keys, and rate limits that slow down research. This reads the public market feeds directly, filtered by status, event ticker, or series ticker, and returns each match in one fixed schema. Get clean, structured prediction market data for trading, research, or analytics without the setup.

Who uses itWhat they scrape Kalshi for
Quantitative tradersBuild datasets of open markets to backtest prediction market strategies
Market researchersTrack which events are being traded and how prices move over time
Data journalistsPull current market prices and volumes for stories on event probabilities
Risk analystsMonitor settlement data and closed markets to evaluate historical accuracy

What it does

This Actor collects Kalshi prediction markets by status, event ticker, or series ticker, and returns each one as a flat row.

  • ๐Ÿ“Š Status filter: collect only open, closed, or settled markets in a single run.
  • ๐ŸŽฏ Event ticker filter: narrow to a specific event like KXPRES for targeted analysis.
  • ๐Ÿ”— Series ticker filter: pull all markets within a series for cross-market comparison.
  • ๐Ÿ“ฆ Bulk collection: set maxItems up to 1,000,000 to grab the entire market universe.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with Kalshi data

๐Ÿ“ˆ Backtest trading strategies.

A quant trader pulls all settled markets with their final prices and settlement values to evaluate how often the favorite won and whether a strategy would have been profitable.

๐Ÿ“ฐ Track event probabilities.

A data journalist scrapes open markets for a major election or economic release, then exports the current prices to chart how implied probabilities shift day by day.

๐Ÿ” Monitor market liquidity.

A risk analyst collects open markets filtered by series ticker to compare bid-ask spreads and volume across related events, flagging thin markets before taking a position.

๐Ÿงช Build research datasets.

A market researcher runs the Actor daily on open markets and stores the JSON output to analyze which categories attract the most trading activity over a month.

Troubleshooting

Why am I getting no results?

Check your filters. If you set status to 'open' but all markets are closed or settled, the Actor returns nothing. Try clearing the eventTicker and seriesTicker fields, or switch status to 'closed' or 'settled'.

The run stops before reaching maxItems.

The Actor stops when there are no more markets matching your filters. Lower maxItems or broaden your filters to collect more.

Some fields are empty in the output.

Not all markets have every field populated. For example, settled markets may have settlement data while open markets do not. Empty fields are normal and reflect the source data.

I get an error about invalid ticker.

Tickers are case-sensitive. Verify the exact ticker on Kalshi's website and enter it without spaces. If the ticker is correct, the market may no longer exist.

The run is slow.

Large maxItems values take longer. Reduce maxItems or narrow your filters to speed up the run. The Actor processes markets sequentially to avoid rate limits.

FAQ

QuestionAnswer
Do I need a Kalshi API key?No. This Actor reads the public market feeds directly, so you do not need to register an app or manage API keys.
What data does each market row include?Each row includes the market ticker, event and series tickers, category, status, current prices, volume, and settlement data when available. The exact fields are shown in the sample output.
Can I scrape only open markets?Yes. Set the status filter to 'open' and the Actor will return only markets that are currently open for trading. You can also choose 'closed' or 'settled'.
How do I filter by a specific event?Use the eventTicker input field. For example, entering KXPRES will return only markets tied to that event ticker.
What is a series ticker?A series ticker groups related markets under one identifier, such as all markets for a particular election or economic release. Use the seriesTicker field to pull all markets in that series.
How many markets can I collect in one run?You can set maxItems up to 1,000,000. The Actor will stop after collecting that many markets, or when no more match your filters.
What output formats are supported?The Actor exports to CSV, JSON, Excel, and XML. Choose the format when you run it or in your storage settings.
Is the data real-time?The Actor reads the current public feeds at the time of the run, so prices and volumes reflect the latest available data. Run it on a schedule to keep your dataset fresh.
Can I use this for commercial trading?Yes, the data is public and the Actor is designed for traders, researchers, and data teams. You are responsible for complying with Kalshi's terms of service.
Does this Actor also scrape Polymarket?No, this Actor only scrapes Kalshi. If you need both platforms, consider the Polymarket + Kalshi Arbitrage Finder actor in the Apify Store.
