Export to JSON, CSV or Excel, or call it from the API. $2 per 1,000 results. No login, no API key, no browser.

The first and only Gemini Predictions scraper on Apify.

Why use it

• All of Gemini Predictions at once. Gemini's own list stops at 1,000 events, so this actor reads every category and merges them. A full run covers 1,200+ live events.
• Ready-to-use prices. Best bid, best ask, last trade, and an implied probability (the bid/ask midpoint) for every outcome, plus Gemini's buy and sell prices for both Yes and No.
• Results too. Switch to settled markets to get the winning side, the settlement value and when it resolved. Useful for backtests and calibration studies.
• Spreadsheet friendly. One row per outcome by default, or one row per event with outcomes nested.
• Fast and cheap. Reads Gemini's public API directly, so a full run takes under a minute.

What you can use it for

• Compare venues: line Gemini prices up against Polymarket, Kalshi or sportsbooks to find price gaps.
• Trading research: track how probabilities move into an event, and backtest on settled results.
• Dashboards and newsletters: show live odds for elections, games, Fed decisions and crypto prices.
• AI agents: give an agent a current read on what markets expect, through the Apify API or MCP server.
