Prediction markets are quickly becoming the financial product that everyone wants a piece of. ION, the trading technology provider, is partnering with Coinbase to support the trading of Kalshi’s event contracts, adding another layer of infrastructure to a market segment that has been growing at a pace few anticipated even a year ago.
The move connects ION’s exchange and clearing technology with Coinbase’s consumer-facing platform, which announced its own partnership with Kalshi back in December 2025. Together, the pieces form a supply chain for event contracts: Kalshi provides the CFTC-regulated marketplace, ION supplies the trading plumbing, and Coinbase offers the storefront where millions of users can place bets on real-world outcomes starting at just $1.
How the pieces fit together
Coinbase first revealed its Kalshi integration during its “System Update” livestream on December 17, 2025. The plan was straightforward: embed event contracts directly into the Coinbase app, covering categories like elections, sports, and economic indicators. Nationwide availability across the US was targeted for late January 2026, with Coinbase Financial Markets handling the brokerage side of the operation.
ION’s role sits further upstream. The company launched its XTP for Event Contracts solution, a platform designed to automate the trading and clearing processes that prediction markets require. The initial rollout happened in December 2025 through a partnership with Wedbush Securities, which allowed for rapid deployment of event-based trading infrastructure. The full product launch followed on April 29, 2026.
For Coinbase, this fits squarely into its “everything exchange” strategy. The company has been vocal about wanting to move beyond pure crypto trading, and event contracts represent a natural expansion. They’re regulated, they appeal to both casual and serious traders, and they create a reason for users to open the app even when Bitcoin is trading sideways.
Kalshi’s explosive growth trajectory
The timing of these partnerships isn’t accidental. Kalshi has been on a tear. The platform reached a cumulative notional volume of $34.5 billion by late January 2026, a figure that would have seemed absurd just two years prior when prediction markets were still fighting regulatory battles in US courts.
Kalshi reportedly raised $1 billion at an $11 billion valuation amid the surging interest in event-driven trading.
Kalshi’s CFTC-regulated status gives it a significant advantage in this environment. While crypto-native prediction platforms operate in regulatory gray zones, Kalshi plays by the same rules as futures exchanges. That makes it a comfortable partner for companies like Coinbase and ION, which have their own compliance obligations to manage.
Why infrastructure matters more than you think
ION’s XTP platform is designed to compress that timeline by providing off-the-shelf technology that exchanges and brokers can deploy without building from scratch.
The partnership with Wedbush Securities is particularly telling. Wedbush is a well-established broker-dealer with deep roots in traditional finance. Its willingness to serve as the initial deployment partner for ION’s event contract technology signals that Wall Street incumbents see real revenue potential in this space, not just novelty.
Coinbase has signaled that it plans to expand liquidity sources for event contracts beyond Kalshi over time.
