Firm names co-founder Josh Gibson as Chief Executive Officer
NEW YORK, Sept. 1, 2026 /PRNewswire/ — Granite River Trading (GRT), a principal digital-asset trading firm, today announced its formal launch, the appointment of Josh Gibson as Chief Executive Officer, and the confirmation of its senior leadership team.
GRT trades its own capital across centralized exchanges, decentralized venues and emerging on-chain markets, with active connectivity to more than 25 trading venues. The firm operates globally, with a distributed team providing continuous coverage across every major trading session. Its activity spans systematic and discretionary strategies, and extends to OTC markets, RWA exchanges and prediction markets. The firm expects its activity to broaden as it scales.
Gibson takes the Chief Executive Officer role, where he will lead the firm’s strategy, commercial growth and global expansion. A co-founder of the firm and a crypto veteran with nearly 20 years of financial-markets experience, he was an early employee at GSR, where he spent five years.
He is joined by a leadership team with deep market-making pedigree. Juan Marquez, Co-Founder and Chief Technology Officer, was previously Head of Engineering at Keyrock, where he led the team behind the firm’s market-making platform. Kalon Jarvis, Head of Trading, has traded derivatives for close to two decades, including senior roles at Auros and Cumberland (DRW), with expertise in algorithmic trading and proprietary strategies.
The launch comes at a point of consolidation across digital-asset trading. GRT has used the period to invest in technology and to add senior talent.
“A lot of firms have pulled back over the past year. We have done the opposite. We are lean, we are well capitalised, and we have been able to bring in people who would not normally be on the market. Digital-asset markets are maturing quickly, and the firms that endure will be the ones with real technology and real discipline behind them.”
— Josh Gibson, Chief Executive Officer and Co-Founder, Granite River Trading
“GRT is built on world-class technology and a disciplined, principal-first approach to trading. We have brought together a team with genuine market-making pedigree, and we are only getting started.”
— Juan Marquez, Chief Technology Officer and Co-Founder, Granite River Trading
“Having traded through several cycles, what stands out here is the discipline. GRT has built the infrastructure to price and execute across venues at scale, and the risk framework to do it consistently.”
— Kalon Jarvis, Head of Trading, Granite River Trading
GRT is actively hiring across business development, trading and compliance as it scales globally. Inquiries: contact@graniteriver.io
