Marble raises $11M seed for AI credit and digital asset trading

Marble, an institutional capital markets firm, launched on November 10, 2026 with an $11 million seed round led by Polychain Capital, according to the company's announcement.

Maven 11, Ripple, Susquehanna Crypto, Lattice, Blockwall Ventures and a group of AI-focused angel investors joined the round. The capital arrives ahead of any product: Marble has not launched anything yet, and its first live offering is slated for January 2027.

Who is running Marble?

Two co-CEOs run the firm, and both come from the institutional side of digital assets. Matt Ballensweig previously served as Global Head of Trading at BitGo. Leon Marshall was formerly CEO of Galaxy Digital Europe.

Polychain Partner Angelo Goepel pointed to the founders' record of "scaling institutional trading and lending across different market cycles." He also framed the opportunity as "a significant opportunity where frontier-market trading meets AI infrastructure credit."

That pairing is the thesis behind the raise. Marble's backers are underwriting two businesses that rarely share a desk: frontier digital asset trading on one side, the private credit financing of AI compute on the other. The first is a fee business tied to execution and custody. The second is a lending book tied to how GPU capacity gets financed.

What does Marble actually build?

Marble organizes around two divisions running on one balance sheet.

Marble Compute builds institutional private credit infrastructure for AI-related needs. It connects lenders with neocloud providers and GPU operators. Neoclouds are newer cloud providers built specifically around GPU compute for AI workloads, and they are the type of counterparty Marble's credit arm is designed to serve.

Marble Markets is the trading side of the house. Its platform is set to span digital assets, real-world assets, prediction markets and computing capacity.

Four markets under one roof is a wide brief for a seed-stage firm, and each leg carries its own operational machinery. Prediction markets settle on events rather than asset ownership. RWAs need an issuance chain and a registrar. Computing capacity requires delivery, not just matching, because a counterparty wants GPU hours rather than screen balances.

• Marble Compute — institutional private credit infrastructure for AI needs, linking lenders with neocloud providers and GPU operators.
• Marble Markets — trading across digital assets, RWAs, prediction markets and computing capacity, with digital asset trading due first in January 2027.

Where does the $11 million go?

The proceeds fund two lines: expanding the team and building out the technology. That includes the trading and custody systems Marble needs to serve institutional clients.

The emphasis on custody says something about who Marble is selling to. A firm pitching to institutional allocators has to keep execution and asset servicing inside structures those buyers can diligence, and Marble's first product in January 2027 is a trading venue rather than a credit book. The credit side, where lender relationships take longer to establish, carries no announced launch date.

When does Marble ship?

Nothing is live today. Initial product launches are anticipated in early 2027.

Digital asset trading is slated to begin in January 2027, making it the first live piece of the Marble Markets offering. The announcement gives no date for Marble Compute, and none for the wider platform beyond the early 2027 window.

What should buyers watch?

Three checkpoints:

• January 2027 — digital asset trading goes live, the first component of Marble Markets.
• Early 2027 — further product launches across the platform.
• No date set — Marble Compute, the AI private credit book, for which the announcement provided no timetable.

The first hard deadline is January 2027, when Marble's trading venue is due to open with its custody arrangements in place. The harder half of the thesis is the credit engine: until a lender signs and a GPU operator draws on a facility, Marble is two executive resumes and $11 million.
