Marble announces its formation and completion of a $11 million seed round led by Polychain Capital
Marble announced today that it has officially been formed and has completed a $11 million seed round, led by Polychain Capital, with participation from venture capital firms and strategic investors including Maven 11, Ripple, Susquehanna Crypto, Lattice, Blockwall and others, as well as some individual investors focused on the AI sector.
Through its two core businesses, Marble provides capital and liquidity to frontier markets worldwide. Among them, Marble Compute is focused on building an institutional-grade private credit system for AI infrastructure, connecting institutional lenders with Neoclouds and GPU operators that are driving the construction of AI infrastructure; Marble Markets is building an institutional trading platform covering digital assets, real-world assets (RWA), prediction markets and computing power markets.
Marble was co-founded by Matt Ballensweig and Leon Marshall, who also serve as co-CEOs. Ballensweig previously served as global head of trading at BitGo, where he was responsible for building and leading its institutional trading business, and earlier co-led Genesis’s trading and lending business. Marshall previously served as CEO of Galaxy Digital’s European business and also worked at Genesis, Apollo and Trafigura. Marble said it will continue expanding its team in the coming months and plans to bring in senior talent from leading trading firms, trading platforms and AI infrastructure companies.

Marble was co-founded by Matt Ballensweig, former global head of trading at BitGo, and Leon Marshall, former CEO of Galaxy Digital’s European business; both have experience in Genesis’s trading and lending business. In the statement, Polychain Capital partner Angelo Goepel emphasized that the two have cross-cycle institutional trading and lending operating experience, and said this would help the company pursue both institutional frontier-markets trading and AI infrastructure credit opportunities.
Marble Compute provides private credit to mid-sized independent Neoclouds and GPU operators, which often struggle to obtain financing from large banks or public markets even when they already have customer commitments to buy computing power. The company plans to connect institutional lenders through both traditional structures and on-chain credit, and to assess equipment, customer credit and operators’ debt-repayment capacity. Marble Markets plans to offer spot digital assets, lending and derivatives, block trading in prediction markets and computing-power forward contracts, and may also involve tokenized stocks after regulatory approval in the future.
On the capital side, this round is a seed round, and the funds will mainly be used for team expansion and infrastructure buildout. The investor lineup includes crypto-native firms (Polychain, Maven 11), payments and infrastructure (Ripple) and market makers (Susquehanna Crypto), matching the company’s positioning. Compared with earlier crypto credit firms, Marble is shifting collateral from crypto assets to AI computing hardware and cash flow supported by customer contracts.
This model aims to fill the financing gap for mid-sized operators in AI infrastructure while extending institutional trading infrastructure into emerging markets such as prediction markets and computing power. In the short term, attention should be paid to the actual financing rollout with Neoclouds and the progress of the trading platform launch; in the medium term, it will depend on the stability of computing-power contract performance and the regulatory and operational complexity of multi-asset collateral. Key metrics to watch are the size of the first credit transactions, institutional client onboarding and business progress at the next financing round.

Institutional private credit and trading platforms can simultaneously provide financing and liquidity tools for the same emerging market, such as AI computing power.
Former crypto trading and lending executives moving into AI infrastructure credit reflect a shift in collateral from crypto assets to contract-backed physical/cash-flow assets.
