Coinbase Taps ION's XTP for Kalshi Prediction Market Clearing
Coinbase has chosen ION's XTP for Event Contracts platform to handle clearing for Kalshi's prediction market products. This deal is part of Coinbase's infrastructure support for what it calls the world's largest prediction market as event-based trading continues to scale.
XTP for Event Contracts is a fully automated, real-time environment designed for creating, resolving, and settling contracts tied to real-world outcomes. For Coinbase, this platform means processing event contracts in real time with minimal disruption to current back-office workflows.
The three firms have been working together since December 2025, when Coinbase and ION first teamed up to help Kalshi list event contracts. ION attributes the relatively fast rollout to XTP's architecture and joint work among the companies on analysis, development, and deployment.
