Kalshi Markets Scraper - Prices, Volume & Odds

Get Kalshi prediction markets with current yes/no prices, volume and open interest, as clean rows ready for a spreadsheet, a dashboard or an AI agent.

The Actor reads Kalshi's public market data API. No API key and no login are needed. With the default settings it reads every open market (around 150,000) in about half a minute and saves the most traded ones.

What you can do with it

• See the most active markets right now, across all categories or in one.
• Track implied probabilities for elections, Fed decisions, weather, sports or crypto over time by scheduling the Actor.
• Find markets by keyword and export them with prices and volume.
• Pull every strike of one event or one series, for example all temperature ranges of a city.
• Download settled markets with their results for backtesting.

• Prices are in US dollars per contract, from 0 to 1. A yes price of 0.26 means the market prices the outcome at about 26%.
• midPrice is the midpoint of the yes bid and ask. It is null when one side of the book is empty.
• volume, volume24h and openInterest are numbers of contracts.
• result is filled for settled markets (yes or no).
• url links to the series page on kalshi.com.

Good to know

• Sorting needs a full read. With a sort order the Actor reads all matching markets before saving the top ones, about 30 seconds for all open markets. Use seriesTickers or eventTickers, or set sortBy to none, when you want a faster run.
• Closed and settled markets go back years. For those, narrow the run with seriesTickers; a single run reads at most 80,000 events.
• Multi-leg combo markets are not included.
• This Actor reads market data only. It does not place orders and does not access accounts.
• The data comes from Kalshi and is provided as-is. It is not financial advice.
