Marble Compute develops private credit financing for independent neoclouds and GPU operators. These companies provide computing capacity for AI workloads but often have fewer financing options than larger publicly traded cloud providers.

Marble connects institutional lenders with these operators through traditional and on-chain credit opportunities. Its underwriting process evaluates equipment, the creditworthiness of contracted customers and the operator's ability to repay debt.

The business also plans to offer compute financing products, including forwards that allow operators to agree on rental prices for computing capacity they will deliver in the future.

Why the Funding Matters

Marble plans to use the funding to expand its team, particularly through senior hires from trading firms, exchanges and AI infrastructure companies.

The investment will support the development of its two businesses. Marble Compute is working to improve financing access for independent AI cloud providers and GPU operators, while Marble Markets is building trading infrastructure for institutions across several asset classes.

Who founded Marble?

Marble was founded in 2026 by Matt Ballensweig and Leon Marshall. The company is headquartered in New York City.

"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. "We're bringing buyers, operators and lenders together so operators can secure customers for their capacity, lock in pricing on the share they want to hedge and raise financing against those cash flows.

Market and Business Growth

Marble is targeting two areas of the capital markets: financing for AI infrastructure and institutional trading across emerging asset classes.

Marble Compute aims to connect institutional capital with smaller neoclouds and GPU operators that need financing to expand their infrastructure. Its proposed financing model will consider equipment, customer contracts and repayment capacity.

Marble Markets is developing products across digital assets, prediction markets and computing capacity. Its longer-term plans include tokenised equities and equity swaps, subject to applicable regulatory approvals.

What Happens Next?

Marble plans to expand its team with experienced hires from financial markets and AI infrastructure businesses.

It will continue developing private credit products for independent computing operators and its institutional trading platform. Some planned products, including tokenised equities and certain financing structures, will depend on applicable regulatory approvals.
