Kalshi Markets Scraper: Live Odds, Weather Markets & Price History

Get live odds for any Kalshi prediction market as clean JSON, CSV or Excel. It covers elections, economics (Fed rates, CPI, jobs), crypto (Bitcoin, Ethereum), sports, weather, AI, companies and more.

Data comes from Kalshi's official public API. There's no login, no API key, no browser and no proxies, which is why runs are fast (usually a few seconds) and don't break when the website changes.

• Order book (orderbook): yes and no price levels with sizes, up to 100 levels deep.

How to use it

Find markets by keyword: keywords: ["bitcoin", "fed", "election"]

Whole categories: categories: ["Economics", "Crypto"]

Exact tickers: seriesTickers: ["KXBTCD"], eventTickers: [...] or marketTickers: [...]. Pair these with an Apify schedule to build a watchlist that updates every few minutes.

Weather markets: set mode: "weather", cities: ["NYC", "Chicago", "Miami"] and weatherType: "high". This covers 144 temperature and rain series worldwide, not just a handful of US cities.

Resolved markets for backtests: status: "settled" returns each market's final result.

Filters:

• minVolume, minVolume24h, minOpenInterest
• minProbability / maxProbability (e.g. only markets priced 5–95%)
• closesWithinHours
• onlyWithQuote

Combo (multi-leg) markets are hidden by default.

Example input

{
  "keywords": ["fed"],
  "status": "open",
  "minVolume": 1000,
  "includePriceHistory": true,
  "historyInterval": "1d",
  "historyLookbackDays": 30,
  "maxItems": 100
}

Pricing

You pay per market returned, and maxItems caps what a run can cost. Price history and order books are included at no extra charge. You also pay nothing for markets that your filters drop.

Use cases

• Traders and quants: track odds, spreads and liquidity; export history for backtests; watch weather brackets before settlement.
• Researchers and journalists: see what the market implies about elections, rates, inflation or company events.
• Dashboards and alerts: schedule a run, then pipe the results to Google Sheets, Slack or a webhook with Apify integrations.

FAQ

Is this allowed? Yes. It only reads Kalshi's public market data API, which Kalshi publishes for exactly this purpose. It doesn't log in or place orders.

Why is a probability sometimes missing? Very new or illiquid markets may have no bid, ask or last trade yet. Use onlyWithQuote to skip them.

Something's wrong or missing? Open an issue on the Issues tab, and it'll be fixed quickly.
