ION Teams Up with Coinbase to Support Kalshi’s Event Contracts

ION has teamed up with Coinbase to support event contract clearing for Kalshi. ION provides trading and workflow automation software, analytics and insights, and strategic consulting globally. Coinbase has selected ION’s XTP for Event Contracts to support its work with Kalshi. The solution provides an automated platform for the creation, resolution, and settlement of event-based contracts.

Real-Time Event Contract Processing

ION’s XTP for Event Contracts gives Coinbase the ability to manage event contracts in real time. It lets the company support execution and processing with minimal changes to its existing operational processes. The platform also supports real-time contract design, the onboarding of tens of thousands of accounts per day, and fully automated processing around the clock.

ION, Coinbase, and Kalshi

ION and Coinbase first partnered to support Kalshi’s listing of event contracts in December 2025. The modern architecture of XTP let the three companies accelerate the deployment. ION, Coinbase, and Kalshi worked together on analysis, development, and rollout. XTP handled high-volume activity for Kalshi, including its first one million trades over Super Bowl weekend during the initial rollout.

One Solution

XTP for Event Contracts lets Futures Commission Merchants (FCMs) run event contracts with their ETD and cOTC business through a single solution. The platform includes native reporting, automated settlement, and multiexchange connectivity. It helps FCMs onboard clients quickly, reduce operational work, and scale as trading volumes increase. ION said leading FCMs already rely on XTP. Now, the company is applying the platform’s real-time processing capabilities to the growing prediction market sector.

What Executives Said

Toni Gemayel, Head of Prediction Markets at Coinbase, said the partnership with ION provides the operational infrastructure Coinbase needs as its event contracts business expands. He stressed XTP’s real-time processing as an important capability for handling increasing prediction market volumes and maintaining back-office stability and execution standards.

Max Crowley, Vice President of Business Development at Kalshi, said XTP adds operational risk management and processing capabilities to the offering. He emphasized that safe and regulated markets need more than exchange rules and oversight. They also need strong operational processes.

Samuel Shorthouse, Head of Client Engagement, Cleared Derivatives at ION, said the company is pleased to work with Coinbase and Kalshi as regulated event-based markets expand. He stressed XTP’s real-time capabilities and helping clients manage growing activity. He also said the collaboration shows ION’s support in this emerging market with infrastructure that is secure, scalable, and sustainable.

Wrapping Up

ION’s partnership with Coinbase brings XTP’s automated and real-time processing capabilities to Kalshi’s event contracts. The three companies have already shown the platform’s ability to handle high volumes.
