The exchange launched a public REST API endpoint on July 30 that serves up trade volume data organized by category, broken down by day or hour in UTC.\n\nThe key word here is “public.” No authentication required. No API keys, no account creation, no hoops. If you can make an HTTP request, you can pull Gemini’s prediction market volume data.\n\n## Why this matters beyond the technical plumbing\n\nGemini Predictions launched on December 16, 2025, as a CFTC-approved Designated Contract Market, which means it operates under the same regulatory framework as traditional futures exchanges. That distinction allowed it to roll out across all fifty US states from day one.\n\nThe platform initially offered fee-free trading to bootstrap activity. By July 2026, Gemini Predictions has surpassed $24 million in cumulative trading volume and crossed 10,000 active users.\n\nApril 2026 was particularly strong, with trading volume jumping 78% month-over-month.\n\n## The revenue picture and Gemini’s broader momentum\n\nIn Q1 2026, Gemini reported total revenues of $50.3 million, a 42% year-over-year increase. The prediction market product contributed approximately $400,000 of that, with more than 20,000 users engaging with the service during the quarter.\n\nThe platform has also traded over 100 million contracts since launch.\n\nUpdates on July 17 added batch-order APIs and new event categories including FIFA World Cup contracts. Batch orders are a quality-of-life improvement for market makers and algorithmic traders who need to place or cancel multiple orders simultaneously.\n\n**Disclosure:** This article was edited by Editorial Team.
