Marble, a new institutional capital markets firm launched on November 10, 2026, has raised an $11 million seed round led by Polychain Capital. Maven 11, Ripple, Susquehanna Crypto, Lattice, Blockwall Ventures and AI-focused angel investors also participated. The company is co-led by Matt Ballensweig, formerly Global Head of Trading at BitGo, and Leon Marshall, formerly CEO of Galaxy Digital Europe. Marble is organized into Marble Markets and Marble Compute. Marble Markets plans to offer institutional access to digital assets, real-world assets, prediction markets and computing capacity, including spot, lending and derivatives trading, prediction-market block trades and over-the-counter compute forwards. Marble Compute is developing private-credit infrastructure connecting lenders with neocloud providers and GPU operators through traditional and on-chain credit structures, including funds, special-purpose vehicles, loan syndications and on-chain vaults. Marble has not launched products yet. Initial launches are anticipated in early 2027, with digital-asset trading scheduled to begin in January. The funding will support hiring and the development of trading and custody systems for institutional clients.
