The Crypto Tape – Cross-Asset Trading with Kaledora Fontana Kiernan-Linn of Ostium

Kaledora Fontana Kiernan-Linn co-founded Ostium in 2022 with a thesis that crypto-native traders would eventually want to trade traditional assets, on-chain, from their existing wallets. Three years later, the numbers are speaking for themselves. Ostium did nearly $6 billion in gold volume in the second half of 2025, with gold running at roughly ten times the volume of Bitcoin on the platform.In this episode of The Crypto Tape, Frank Chaparro sits down with Kaledora to discuss the macro-driven shift in trader behavior, why prediction markets are creating the next wave of active traders, and what it takes to build a product that earns the trust of traders moving serious size without ever feeling like a toy.They also get into the $10 trillion CFD market Ostium is targeting and the platform’s approach to scaling.
