Galaxy has launched an over-the-counter prediction markets desk for institutional clients, pushing event-contract trading further into the same infrastructure used for larger digital asset trades.

The company said the service will run through its Global Markets trading desk and is aimed at hedge funds, family offices, and other professional investors. At launch, Galaxy said it will focus on non-sports contracts listed on Kalshi and Polymarket, including economic, political, geopolitical, and other event-driven markets.

The first disclosed trade was a $10 million position with Arca, a crypto-native hedge fund, on Kalshi contracts tied to outcomes around the CLARITY Act. Galaxy said its OTC desk facilitated the trade on a bilateral basis, giving Arca institutional-scale liquidity without routing the order through a retail interface.

The move matters because prediction markets have recently drawn both institutional attention and regulatory pressure. Galaxy is positioning the desk as a way for clients to express views around discrete events while also pairing those positions with hedges in equities, commodities, crypto, or other assets.

For now, the announcement is narrower than a broad public exchange launch. Galaxy is acting as a trading counterparty and facilitator for large clients, not opening a consumer product. But it adds another sign that event contracts are moving from retail prediction platforms toward institutional market structure.
