Event Contracts is ION's latest extension to its flagship XTP solution, offering a fully automated, real-time platform for the creation, resolution, and settlement of event-based contracts. It provides Coinbase with the ability to confidently support execution and processing of event contracts in real-time with minimal impact to existing operational processes while supporting real-time contract design capability, onboarding of tens of thousands of accounts per day, and fully automated 24/7 processing.

ION and Coinbase partnered to support Kalshi's listing of event contracts in December 2025. XTP's modern architecture has enabled the adoption of an accelerated deployment timeframe through three-way collaboration between ION, Coinbase and Kalshi, who worked to expedite analysis, development, and rollout. During the initial rollout, XTP demonstrated its ability to support high-volume activity for Kalshi, including processing its first one million trades over Super Bowl weekend.

XTP for Event Contracts provides Futures Commission Merchants (FCMs) with a unique opportunity to run event contracts alongside existing ETD and cOTC business in a single solution, thanks to native reporting, automated settlement, and multiexchange connectivity. The result is fast onboarding, low operational lift, and seamless scaling as the volume grows. Already relied upon by leading FCMs, XTP now brings the same robustness and real-time processing to the fast-growing prediction market sector.
