Granite River Trading Enters Digital Asset Market with Veteran Team

The firm operates globally with a distributed team providing continuous coverage across every major trading session. Its activity spans systematic and discretionary strategies, extending into OTC markets, real-world asset exchanges, and prediction markets. Josh Gibson, who spent five years at GSR, leads the firm’s strategy and commercial expansion alongside co-founder and Chief Technology Officer Juan Marquez, formerly of Keyrock. The leadership bench is completed by Head of Trading Kalon Jarvis, a veteran of Auros and Cumberland.

While many competitors retreated over the past year, Granite River Trading utilized the market downturn to invest in infrastructure and recruit senior talent. The firm currently maintains a lean, capitalized structure designed to capitalize on the increasing maturity of digital-asset markets. As the company scales its global operations, it is actively expanding its workforce across business development, trading, and compliance divisions.
