Manifold Prediction Markets Scraper
Scrape prediction market data from Manifold Markets by search query or chronological list, up to a million markets per run. Each market comes with its current probability, volume, liquidity, close date, and resolution status. No API key required. Export to CSV, JSON, Excel, or XML.
Manifold Markets is a platform where users create and bet on the outcome of any future event, from politics to tech. Tracking these markets manually is slow, and the official API requires authentication and coding. This Actor reads the public market feeds directly, letting you collect thousands of markets filtered by status, sorted by score or liquidity, and enriched with full descriptions on demand.

Troubleshooting
Why am I getting no results for my search query?
Try a broader or shorter search term. Manifold's full-text search matches against market titles and descriptions, so a very specific phrase may return zero results. Also check that your status filter is not too restrictive.
The run is taking a long time to finish.
If you enabled 'Fetch full descriptions', the Actor makes one extra API call per market, which slows things down. Disable this option for faster collection, or reduce the maximum number of markets.
Why do some markets have missing probability or volume?
Newly created markets may not yet have any trades, so probability and volume can be zero or null. This is expected behavior and reflects the market's actual state on Manifold.
I am getting fewer results than my maxItems setting.
The Actor stops when it runs out of markets matching your filter and sort criteria. If you are searching for a niche term or using a restrictive filter like 'Closing today', the total available markets may be less than your requested maximum.
Can I scrape a specific market by URL?
This Actor is designed for bulk listing and search, not single-URL scraping. Use search mode with a unique keyword from the market title to isolate a specific market.
FAQ
| Question | Answer |
|---|---|
| Do I need a Manifold API key to use this scraper? | No. This Actor reads the public market feeds directly, so no API key, registration, or authentication is required. |
| What data does each market row contain? | Each row includes the market title, current probability, volume, liquidity, creator name, close date, resolution status, and the market URL. If you enable full descriptions, the complete body text is also included. |
| Can I search for specific topics? | Yes. Switch to search mode and enter a keyword like 'election', 'AI', or 'crypto' to find markets matching that term in their title or description. |
| How do I get only markets that are closing soon? | Use the filter dropdown and select 'Closing today', 'Closing this week', or 'Closing this month' to narrow results to markets with imminent close dates. |
| What is the difference between list mode and search mode? | List mode returns markets in chronological order from the main feed. Search mode performs a full-text query across all markets and returns the most relevant matches. |
| How many markets can I collect in one run? | You can set the maximum up to 1,000,000 markets per run. The Actor will paginate through results until it reaches your limit or no more markets are available. |
| Does fetching full descriptions slow down the run? | Yes. Enabling full descriptions makes one extra API call per market to retrieve the body text, which increases total run time. Leave it off for faster collection of summary data. |
| Can I filter by market resolution status? | Yes. The filter dropdown lets you select Open, Closed, or Resolved markets, or show all markets regardless of status. |
| What export formats are supported? | You can export your dataset in CSV, JSON, Excel, or XML format from the Apify platform. |
| Can I sort markets by liquidity or volume? | Yes. The sort dropdown includes options for liquidity, score, newest, subsidy, popularity, resolve date, and close date. |
