The Winklevoss exchange adds batch order APIs, World Cup markets, and watchlist tools as its prediction platform crosses $24M in trading volume
Gemini’s prediction markets platform is getting a serious upgrade. The crypto exchange has rolled out batch order APIs, dedicated FIFA World Cup contracts, and watchlist functionality for its Predictions product.
The headline addition is the batch order API. It lets users place or cancel up to 20 orders in a single authenticated request. Instead of manually submitting trades one at a time, power users and automated strategies can fire off an entire book of positions in one shot.
The platform also added watchlist tools, letting users track specific contracts without actively trading them. Real-time pricing has been baked in alongside dedicated category pages for the 2026 FIFA World Cup, giving the upcoming tournament its own market hub within the app.
An AI-powered feature called the Command Center arrived in an October 2026 update. It delivers personalized market intelligence and portfolio signals directly inside the app.
The Predictions platform works on a simple structure: yes/no event contracts, settled in USD at either $1 or $0. Every contract price is a market-implied probability. A contract trading at $0.65 means the crowd thinks there’s roughly a 65% chance the event happens. All orders are limit-based, keeping execution predictable.
Gemini Predictions launched on December 16, 2025, available across all 50 US states via iOS and web, with Android support added afterward. The exchange operates the platform under regulatory oversight from the Commodity Futures Trading Commission.
By early 2026, the platform had crossed 10,000 active users and more than $24 million in cumulative trading volume. Gemini also dropped trading fees for an initial promotional period. The batch order API documentation was last updated on July 17, 2026.
