Marble raises $11M seed led by Polychain to finance AI compute and run institutional trading

Marble has launched with an $11 million seed round led by Polychain Capital. Maven 11, Ripple, Susquehanna Crypto, Lattice and Blockwall joined, alongside AI-focused angels.

Marble is a capital markets firm led by co-founders and co-CEOs Matt Ballensweig, previously global head of trading at BitGo, and Leon Marshall, former CEO of Galaxy Digital's European business.

It runs two units. Marble Compute originates, underwrites and structures private credit for independent neoclouds and GPU operators, through traditional and on-chain credit, looking at equipment, the creditworthiness of their customers and each operator's ability to service debt. Marble Markets is building institutional trading in digital assets, prediction market block trades and over-the-counter forwards on computing capacity.

"A lender wants to know who's buying the compute, at what price and for how long," Marshall said.
