Kalshi Markets Scraper

What does Kalshi Markets Scraper do?

Kalshi Markets Scraper returns live Kalshi prediction market data: yes and no bid and ask prices, last traded price, volume, open interest, liquidity, and open, close and expiration dates. Filter by category, market status or a keyword to pull only the markets you care about, whether that is election odds, Fed rate calls, or weather and sports contracts. Pricing is per result, so a filtered run only charges for the rows you actually get.

Data source

Data comes straight from Kalshi's public trade API (api.elections.kalshi.com/trade-api/v2/events), the same JSON feed the Kalshi site itself calls, so prices and volume are as fresh as the exchange.

Why use it?

• Track prediction market odds for elections, economic data releases, or news events as a leading indicator.
• Feed a spreadsheet or dashboard with live contract prices and volume without hand copying from the site.
• Screen markets by category or keyword to build a watchlist, for example every Fed rate or weather market.
• Replace manually checking the Kalshi site for price moves with a scheduled run that lands in a database or Sheet.

How to use it

1. Open the Actor and set the category, status or keyword filters, or leave them blank for the most active open markets.
2. Click Start. Download results as JSON, CSV or Excel, or read them through the API.
3. Add a Schedule and an Integration (Slack, Google Sheets, webhook) to get price updates automatically.

Input

Field	Description
category	Only return markets in this category (Politics, Sports, Crypto, and so on). Leave blank for all categories.
status	Market status: open (trading now), closed (awaiting settlement), settled (final result) or unopened (scheduled). Defaults to open.
keyword	Only return markets whose title or subtitle contains this text. Leave blank for no filter.
seriesTicker	Only return markets in one series, for example KXELONMARS. Leave blank for all series.

Pricing

Pay per event: a small fee when a run starts, then a fixed price per result returned. You only pay for records that pass your filters. Set maxResults to cap any run.

Limitations

• Read only: order book depth beyond best bid and ask, and any account or trading data, are not included since those require a login.
• Category and status use the values Kalshi assigns to each market, so a market Kalshi has not tagged with a category will not match a category filter.
• Keyword matching is a plain text search over the market title and subtitle, not a full text search across market rules.

FAQ

Is this legal? The Actor reads market data Kalshi's public API publishes for any visitor without a login and stores only that market data. You are responsible for how you use the data.
