Marble raises $11 million seed led by Polychain Capital
Marble Group raised an $11 million Polychain-led seed for GPU credit and multi-market trading. Its site says the firm still deals only for its own account.
Marble has raised $11 million in seed equity, and that figure is not a GPU loan book. Marble Group said on November 10, 2026 that Polychain Capital led the round, with Maven 11, Ripple, Susquehanna Crypto, Lattice and Blockwall also named, plus other investors and AI-focused angels. The New York firm is building two businesses: Marble Compute, private credit for independent neoclouds and graphics-processing-unit (GPU) operators, and Marble Markets, institutional trading across digital assets, real-world assets (RWAs), prediction markets and compute forwards. In equipment finance, a contracted offtake has never been the same thing as cash already with the lender. Marble's site is stricter than the release. Marble Group, Inc. says it does not currently provide services to the public, buys, sells and holds digital assets only for its own account, and is not registered or licensed with the Securities and Exchange Commission (SEC), the Commodity Futures Trading Commission (CFTC), the Financial Crimes Enforcement Network (FinCEN), the New York Department of Financial Services or any state money-transmission regulator.
The founders
Co-CEOs Matt Ballensweig and Leon Marshall founded Marble. Ballensweig was most recently global head of trading at BitGo, after co-heading trading and lending at Genesis. Marshall was chief executive of Galaxy Digital's European business, with earlier roles at Genesis, Apollo and Trafigura. The site also lists Bridgewater among Ballensweig's earlier stops; the release does not. AlleyWatch's New York funding report for November 10, 2026 records the same $11 million Polychain-led seed and a 2026 founding. Marble Compute is for operators that lack the public-market and large-bank funding open to listed neoclouds, even when customers have committed to capacity. It plans to originate, underwrite and structure financing for lenders, in conventional and on-chain form, judging the equipment, customer credit and the operator's ability to service the debt. Compute forwards would fix a rental price now for capacity delivered later. Single-opportunity funds, then multi-opportunity funds, are subject to applicable regulatory approvals. The compute pages go further, describing private credit secured by GPUs and offtake contracts.
Angelo Goepel, partner at Polychain Capital, said the founders "have built and run institutional trading and lending businesses at scale through multiple market cycles, and they understand market structure from the inside." Chase Lax, chief executive of Susquehanna Crypto, said the firm sees "every day how quickly market structure is evolving." Balder Bomans, chief investment officer at Maven 11 Capital, said Maven 11 had "worked and traded with both Matt and Leon over the years through BitGo and Galaxy." Ripple, Lattice and Blockwall are not quoted. A Ripple investment is not a mandate for Ripple Prime's financing and clearing of Brevan Howard funds. No exchange or custodian has announced a Marble integration. Closer parallels are Luxor's $16 million raise around AI-compute trading, reported on October 28, 2026, and the CFTC compute-derivatives notice this desk has already treated as a manipulation question.
"Two GPU operators can buy identical hardware and raise very different amounts of debt against it. A lender wants to know who's buying the compute, at what price and for how long," said Leon Marshall, co-founder and co-CEO of Marble, in the November 10 release.
The release still sketches a client platform: institutions facing Marble as counterparty, posting assets at participating custodians and brokerages instead of prefunding each trade. Spot, lending and derivatives in digital assets, prediction-market block trades and over-the-counter compute forwards are in development. Tokenised equities and equity swaps come later, again subject to applicable regulatory approvals. Prediction-market structure is still a live question, including Polymarket's decision not to auto-convert existing positions. FinTech Global's November 12 account follows the two divisions. It does not override Marble's notice that approvals, and any client service, may not arrive.
No custodian is named, so collateral is a design, not a live rail. BitGo's purchase of NYDIG's derivatives desk is a different deal, and Galaxy is not an investor here. The $11 million funds the firm. Any loans would sit in funds the release has not launched. Interest logged at marblegroup.xyz is not an onboarded client. For United Kingdom readers, the site limits the promotion to Article 19 investment professionals and Article 49 high-net-worth entities, and it tells retail clients not to rely on it. That is not an authorisation. Until such a fund launches, or Marble obtains a registration it says it lacks, the firm is a proprietary digital-asset book with a project to intermediate compute credit and frontier-market trading. On the company's wording, Marble is not a broker, dealer, exchange or money transmitter.
