Marble launches with $11 million seed led by Polychain to finance GPU operators and neoclouds

Nov 10, 2026
Founded by former BitGo and Galaxy executives, Marble is building private credit for independent AI cloud and GPU operators and a trading platform that includes compute forwards.

New York-based Marble launched with an $11 million seed round led by Polychain Capital, the company said. Maven 11, Ripple, Susquehanna Crypto, Lattice and Blockwall also participated.

Former BitGo trading executive Matt Ballensweig and Leon Marshall, former CEO of Galaxy Digital's European business, founded Marble and serve as joint CEOs. Its Marble Compute business will originate, underwrite and structure private credit financing for independent AI cloud providers and GPU operators.

Marble is also building an institutional platform for spot trading, lending and derivatives across digital assets, prediction markets and compute capacity. Its plans include compute forwards that let operators agree today on a rental price for capacity they deliver later. Subject to regulatory approvals, Marble intends to finance these deals through single-opportunity funds.
