Coinbase, Ion Boost Prediction Market Trading with Kalshi Partnership
Ion, the trading technology provider, has partnered with Coinbase to enhance the trading of Kalshi's event contracts. This move is part of a larger trend in the financial industry where prediction markets are gaining popularity.
The partnership connects Ion's exchange and clearing technology with Coinbase's consumer-facing platform, which integrated Kalshi's event contracts in December 2025. Kalshi provides the CFTC-regulated marketplace, while Ion supplies the trading plumbing, and Coinbase offers the storefront for users to place bets on real-world outcomes.
Kalshi has experienced explosive growth, with a cumulative notional volume of $34.5 billion by late January 2026. The platform's CFTC-regulated status gives it an advantage over other prediction platforms operating in regulatory gray zones.
